A complete hardware and software solution for fully-featured digital cable, satellite and terrestrial system, it is based around a powerful, programmable embedded microprocessor core, allowing manufacturers to develop and rapidly evaluate system designs and test application software. This programmability is the key to maintaining flexibility and reducing risk. Application software can be easily modified to meet changing requirements, so highly featured and differentiated STB designs can be brought quickly to market. It also allows flexible handling of graphics, so manufacturers can implement menus, electronic program guides and the sophisticated graphics-based features expected by today's users. Sophisticated hardware is supported by a full suite of software, developed in partnership with customers to meet real-world needs and provide the reliability required for consumer electronics products. 1999 May 05 5 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept 2.2 Reference design goal 2.3 2.3.1 Benefits KEY SYSTEM BENEFITS OM5721 The Philips STB concept STB5660 is a reference design of a complete hardware and software solution intended for the digital satellite receiver Set-Top Box market. This reference design addresses the potential customer base who is targeting the new world of digital media broadcasting. The reference platform for a Set-Top Box combines the key ICs, the SAA7214 transport MPEG source decoder and the SAA7215 AVG decoder/video encoder, and the software to run a Set-Top Box. As in many cases a platform is a stepping stone from which evolution and specification enhancements can be launched. The first reference design of the platform contains the necessary functions which demonstrate the performance and capabilities of the system. Enhancements in the ICs as well as for SW modules will be released during the lifetime of the platform. The convention which has been used is that backwards compatibility is guaranteed within the platform (STB5000 range). The main objectives are: * Firstly providing this complete system, greatly reduces the required investments needed in scarce design resources, and helps customers focus on building a position and responding quickly to the market demand * Secondly, an advantage of the reference design approach is that the system consisting of complex functions realized in silicon and software can be validated in tangible results * Thirdly, to create a stable platform from which customized solutions can be derived faster. It is expected that in the coming years the market will grow in all segments, satellite, cable and terrestrial; and that the captive broadcasters gradually open up their system, focusing more on the services rather then the contents of the box. Their service role at the beginning is to create the market by having box content, then it will change towards the real core service activities bringing content and new services to the home. This changing behaviour of the service providers calls for the semiconductor providers to offer competitive solutions, enabling the future dreams of the service providers. This implies that in order to plan the evolution of the Set-Top Box functionality, one must be positioned and in control of the whole system. * STB5660 offers a good compromise between flexibility, performance and integration of functions which leads to a very attractive price/performance offer * The SAA7214 performs the descrambling, demultiplexing and control of the STB while the SAA7215 performs the media processing functions such as MPEG2 audio video and graphics processing. The communication between the two ICs as well as the memory partitioning and management have been designed so that a true unified memory concept can be implemented with no performance degradation. * Within the STB family of products, HW and SW footprints will be maintained to ensure the maximum possible reuse of resources * Philips offering the most comprehensive portfolio of ICs combined with our well known technological capabilities brings the best on a complete system level. This in combination with our local technical support centres gives the customer a fast and secure inroad to the new field of emerging technology. 2.3.2 KEY IC BENEFITS * SAA7214 incorporates a low cost high performance 32 bits MIPS processor with 4 kbytes instruction cache and 1-kbyte data cache. In addition a 4-kbyte second-level cache, designed for SW optimization but can also be used for `last minute' CPU intensive software patches is offered to software developers, boosting application performance. * A flexible hardware/software partitioning and optimization for DVB TS demultiplexing has been designed targeted to Canal+ specification. This partitioning makes parsing of incoming stream in hardware, in order to off-load the processor and makes most of the processing from system memory by the MIPS processor, which leaves to software developers the freedom to allocate the right priority at the application level for MPEG system data handling. * All required DVB/MPEG2 system services are covered by SAA7214, such as full DVB descrambling, section filtering with 32 PIDs handled in hardware and more if required in software, TS/PES filter for maximum flexibility in the service handling and edition (time base discontinuity) 1999 May 05 6 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept * In terms of interfaces, the SAA7214 interfaces with basic STB peripherals such as UART, smart card interface, IEEE 1284, but also with the next generation high speed interfaces such as IEEE 1394 * SAA7214 is able to control with a high speed clock (40.5 MHz) DRAMs, Flash, EEPROM and is able to control the SAA7215 as a memory mapped device with a maximum sustained rate of 40.5 Mbytes/s, which enables fast graphic update in the second SDRAM * SAA7215 has a scalable memory architecture: 16 Mbits for low-end and 32 Mbits for mid/high-end applications. Furthermore, there is a full decoupling of MPEG processing and graphics/CPU control buses and control, which offers a high bandwidth and low latency for CPU when accessing the graphics memory. * SAA7215 features 5 independent graphics planes that can address all the known digital TV video and graphics requirements: - Background: where still pictures can be displayed in the background - Foreground: where broadcast graphics and the user interface can be displayed - Video: where still or moving video is displayed - Cursor: implemented in hardware to offer fast responses times. OM5721 * Graphics are processed internally in high resolution RGB 4 : 4 : 4 format which provides the best quality in graphics rendering as well as for mixing with video in 4 : 2 : 2 format * A dedicated Data Manipulation Unit (bit block transfer type) offers very fast block move and data manipulation during the transfers. This can be used to perform scaling of graphics, transfers from 4 : 2 : 0 to CLUT or RGB formats, or fast block move in MPEG or graphics SDRAMs. * SAA7215 offers flexible scaling features, including letter box conversion that is now becoming a needed features for broadcasters * Two independent mixed video/graphics and video-only signal paths are implemented and allow software disabling of the user interface for recording on VCR * Integrated digital video encoder with Y/C, CVBS and RGB outputs reduce the Bill of Materials (BOM) and also the board space, while still offering the possibility to have access to the YUV digital bus through CCIR-656 interface. * SAA7215 is ready for future audio features such as AC-3 or high fidelity LPCM audio, such as requested by the world-wide DVD standard, but also for high-end STB in the USA. SAA7215 processes LPCM audio data and can interface gluelessly with an external multi-channel audio decoder such as the SAA2505, through IEC 958 interface. 1999 May 05 7 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept 3 BLOCK DIAGRAM OM5721 handbook, full pagewidth GENERAL SOFTWARE RESOURCES FEATURE DEMONSTRATION APPLICATION APPLICATION LAYER FRONT PANEL COMMS PSI PROCESSING TELETEXT PROCESSING SATELLITE FRONT-END GRAPHICS LIBRARY IEEE 1394 OPERATING SYSTEM ABSTRACTION (OSA) SYSTEM CONTROL LAYER REAL-TIME KERNEL (RTK) AV DECODER SMART CARD FLASH FRONT PANEL DEBUG NVM MSP IEEE 1394 IEEE 1284 SDD BROAD SUPPORT PACKAGE (BSP) SATELLITE TUNER PLATFORM LAYER I2C-BUS PARALLEL I/O LNB UART DRIVERS FCE047 Fig.1 Software block diagram. 1999 May 05 8 This text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here in _white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here inThis text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader. white to force landscape pages to be ... 1999 May 05 handbook, full pagewidth Philips Semiconductors STB5660 (Set-Top Box) STB concept EEPROM 32 KBYTES x8 TUNER I2C-BUS EEPROM 256 KBYTES x8 DRAM 2 MBYTES FLASH 2 x 2 MBYTES TSA5512 I TDA8060 SD1288MK2 Q TDA8044 SDD SAA7214 TMIPS 1394 L + PHY BUFFERS RGB IEEE 1394 IEEE 1284 RS232 9 FRONT PANEL CONTROL AV MICRO 87C524 PES LR UDA1320 DAC SCART SAA7215 TMIPS SVHS (Y+UV) AUDIO UART CVBS smart card TDA8004 TDA8004 16-MBIT VIDEO/ GRAPHICS RAM 16-MBIT GRAPHICS/ CPU DATA RAM smart card FCE046 Product specification OM5721 Fig.2 Hardware block diagram.

SAA7214 receives transport streams through a versatile stream input interface capable of handling both byte-parallel and bit-serial streams, in various formats, supporting data streams up to and including 13.5 Mbytes/s (108 Mbits/s). The stream data is first applied to an on-chip descrambler incorporating DVB descrambling algorithms, on the basis of 6 control word pairs stored in on-chip RAM. Demultiplexing is subsequently applied to the stream, to separate up to 40 individual data streams. The demultiplexer section includes clock recovery and timebase management. Program Specific Information (PSI), Service Information (SI), Conditional Access (CA) messages and private data is selected and stored in external memory, for subsequent off-line processing by the internal R3000 microcontroller core.

Typical parts are Real-time operating system functionality, C-library and debug components. 5.3 System Control layer * Real-time kernel * Board support package * Operating system abstraction package. 5.1.2 APPLICATION LAYER Part of the System Control layer provides functionalities which are a compound of device driver functionality. Examples of the system control layer components are teletext, which uses the TS/PES package a part of MSP device driver and the AVG device driver. Also the front-end satellite component is a functional layer component, it uses the LNB device driver, the Satellite Tuner device driver and the TDA8044 device driver. 5.4 Platform layer * Feature demonstration application. 5.1.3 SYSTEM CONTROL LAYER * Graphics library * PSI processing * Front panel communications * 1394 * Satellite front-end component * Teletext processing component. 5.1.4 PLATFORM LAYER * MPEG System Processor (MSP) * Audio/Video/Graphics device driver * Front Panel device driver * Flash Memory device driver * Non-Volatile Memory device driver * Debug UART device driver * IEEE 1394 device driver * Smart Card device driver * IEEE 1284 device driver * LNB device driver * Satellite Tuner device driver * TDA8044 device driver. 5.1.5 I/O DEVICE DRIVERS The platform layers consists of set of platform drivers each controlling a Set-Top Box functionality that is implemented in hardware. Examples of a Set-Top Box functionality are video decoding, audio decoding and section filtering. It is possible that more than one platform driver can control a physical hardware component (IC) if this component provides a set of Set-Top Box functions. The interface of a platform driver consists of generic set of functions. It is the intention not to directly specify hardware interface functions but MPEG/DVB related functions. In this way future generations of controlled hardware use the same sub-set of interface functions. Some platform drivers do not directly interface with the hardware but use an I/O platform driver. Platform drivers are not allowed to communicate with each other. If communicating is required between platform drivers it is under control of a component located in the functional layer. The I/O platform drivers provide the functions when a device driver does not directly have access to the hardware. Examples of I/O device drivers are an I2C-bus device driver and an UART device driver. * Parallel I/O device driver * I2C-bus device driver * UART device driver. 1999 May 05 12 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept 5.5 Application layer 5.5.3 TUNING MENU OM5721 This layer has been limited only to demonstrate the possibilities that can be implemented at the application layer. 5.5.1 TOP LEVEL MENU 5.5.3.1 Transponder setup The transponder can be setup automatically or manually. Selecting the automatic option gives the user the possibility to sweep the band over a particular frequency range at all symbol rates. All transponders found will be logged and stored to NVM. The sweep can be started by pressing the start button via the user controls. Selecting the automatic network option will give the user the possibility to sweep the band over a particular frequency range at a user defined symbol rate. The Network Information Table (NIT) from the first transponder found will be read and the services known in this NIT will be logged and stored to NVM. Table 4 ITEM Source Program setup OPERATION The source of the transport stream can be selected between tuner and stream server. In Tuner mode the ability to change the selected transponder is available. Shows the current transport stream and the possible audio PIDS for the selected service. The service can be selected and the audio PID chosen. Main menu options: * Installation menu * Tuning menu * Feature demonstration menu. 5.5.2 INSTALLATION MENU The installation menu is used to select the board configuration options. The selected options are stored to NVM. Table 3 Board configuration options CONFIGURATION OPTION On/off DiSEqC LNB and Single or Dual band; note 1. Pin 16 control (RGB or composite video signalled). Allows selection of 16 : 9 or 4 : 3 TV screen. ITEM LNB setup Video standard PAL or NTSC; default PAL. SCART Display Note 1. With non-DiSEqC LNBs the control is simply by 14/18 V switching for polarity and in the case of a Dual band the use of 22 kHz signal (no modulation) selecting the High Band. With DiSEqC LNBs the control is by sending DiSEqC commands via modulation in the 22 kHz signal. (This means DiSEqC level 1). Listing Selecting the manual option provides the user with the ability to enter additional transponder data, or to adjust transponders found with an auto setup. To add a transponder the correct frequency, symbol rate, polarisation and Forward Error Correction (FEC) rate are required. 1999 May 05 13 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept 5.5.4 Table 5 FEATURE DEMONSTRATION MENU Screens highlighting the main features of the Philips SAA7214/SAA7215 chip-set. FEATURE OM5721 SCREEN Audio Audio routing and Dual channel Mute Balance Beep LPCM demonstration Audio routing options; mono, stereo, LL, RR. Dual channel options; Channel 1, Channel 2, both (1-L, 2-R). Sound muted Control via a text box for left/right balance Control of the volume, frequency and duration; the beep can then be heard. Show the possibility of decoding Linear Pulse Code Modulated (LPCM) audio samples. This besides the decoding of normal MPEG audio although both cannot be not done at the same time. This feature is for example used to play uploaded audio samples. A command is given when the audio and video decoding is running. This command will start the demonstration. The function itself will play about 1 second of LPCM audio and will continue with normal MPEG audio and video decoding afterwards. IEEE 1394 IEEE 1394 disable Smart card Smart card PC download PC download When selected, the MPEG board will wait for the download of a bit map picture, via the IEEE 1284 port. Upon completion of the download the picture will be displayed, the progress of the download is also displayed. A service scrambled using the default keyword will be descrambled upon insertion of a Smart card which contains authorization to use the default keyword. I/O of IEEE 1394 traffic can be disabled. IEEE 1394 will carry on relaying any IEEE 1394 between the two IEEE 1394 ports. Also choose between input/output of data into systems. MIPS performance MIPS Performance Block copy This will show the MIPS performance in drystones under the current setup. To show a fast block copy, a bit map picture is copied across the screen. This function is also supported in hardware but handling this in software makes the function more flexible. The actual copying is executed in the SAA7215 hardware by the DMU. Software however has to upload the picture, initialize and start the DMU with correct parameters. The cost however compared to the hardware tiling is processor and memory use. Graphics Text and Drawings Fast transfer Planes demo Fade Tiling Hard-edge wiping Soft-edge wiping 1999 May 05 A combination of different fonts and line drawings to demonstrate colour depth and resolution capabilities. Fast transfer feature; via IEEE 1284. Demonstration of the different graphics layers, by displaying quarter screen video over a MPEG I frame background with superimposed text and cursor. Combination of video and graphic layers showing fading in and out of the graphics layer. One smaller picture is displayed multiple times in a user selectable rectangle. Two pictures in one plane, overlapping each other where the user can move and select the pictures Two user selectable and movable pictures in two planes, with transparency in the pictures. 14 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept OM5721 SCREEN Anti-flickering FEATURE The anti-flickering demonstration highlights the functions available in the SAA7215 to reduce the line flickering in graphics regions. During this demonstration, 2 graphics regions are displayed. One with anti-flickering and one without. The contents of the bit map in the regions is one that shows flickering without anti-flicker measures active. Video and audio decoding are still active and visible during the demonstration. A picture of the running video is grabbed and displayed 14 of its original size as a 16-bit, bit map on a graphics plane. The picture data of an I or P picture is copied from a frame store to SDRAM2 memory. During the copy the format of the data is converted from 4 : 2 : 0 format to 4 : 2 : 2 and converted into the graphics memory bit map format. Then the picture is displayed on the screen. The demonstration runs continuously. It displays the running video while a graphics region 14 of the screen size is in the top left corner. This graphics region is showing the I- and P-pictures of the running video. Grab frame store to OSD and scale 14 continuously location Scale 19 of 16 bit per pixel graphics location Menu Scaling Cut-out This demonstration shows a 16 bit /pixel bit map in an OSD region on the screen. This picture will be scaled to a factor 14 and 19 of the original size and displayed on the screen, after the original is removed. The scaling is done by using a software routine that executes a DMU program. During the demonstration, audio and video is playing. During all the demonstrations, graphics regions with menu bars and buttons are visible for control of the demonstration. Display of 16 : 9 video on a 4 : 3 display by cutting out 4 : 3 centres and panning/scanning. This demonstration shows the pan/scan control via the left/right cursor keys. This function would usually be under control from data in the transport stream. Display of 16 : 9 video on a 4 : 3 display using letter-boxing. Allows a window to be selected using the cursor; the video will then be resized to fit the selected window. Letter-box Continuous horizontal, vertical steps Video control Video control Teletext Teletext Debug Event logging Scan, freeze, play, stop Switch on and off of the VBI insertion by using a graphics region in VBI lines. User enabled event logging provided via the RS232 debug socket. 1999 May 05 15 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept 6 DEVELOPMENT ENVIRONMENT 6.2 How to get started OM5721 This chapter describes how you can develop your own STB5660 application, what environment you need. What hardware and software interface the system provides. It answers the question what you need to start developing your application. In addition it will tell you what you will receive with the system that gets you on your way and shorten development time and reduce the costs involved. 6.1 Summary of the STB5660 kit When you receive the STB5660 development system it will offer you a complete Set-Top Box system with all needed documentation for development. This will give you a `plug and play' solution to test and develop a system based on this platform. 6.1.1 THE HARDWARE The first day you receive the system you can hook up a satellite dish or transport stream (DiSEqC or not), a TV, connect power to the system and it will start with the FDS program. This demo gives you a menu driven interface to the system. You can test and experiment with all main features of the system. See how fast the On-Screen Display functions, try out the IEEE 1394 interface to a similar board, look at window tests, try out teletext, etc. This will give you an understanding of the system and its possibilities. 6.3 Hardware interface with the STB5660 This consists off a satellite front-end board, a front panel with the display and IR-receiver, a main board, smart card unit, the remote control and all cables needed to make the necessary connections. On the main board you will find a programmed EPROM and Flash memory. 6.1.2 THE SOFTWARE Besides the dish and the TV (SCART, SVHS, CCIR 656 YUV) there is an interface to IEEE 1394, SPDIF (multi-channel audio decoder, to a PC via RS232 and IEEE 1284 (Centronics), a debug socket (ROM emulator, I/O), JTAG connector (boundary scan testing), smart-card unit and a remote control. To use a ROM emulator there is an I/O connector on the main PCB where an extension board fits on the debug connector. This extension gives you access to two footprints for 1-Mbyte ROMs. 6.4 Software interface with the STB5660 You will receive not only the binary executable, but also all source codes in C, header files and documentation files. The software will include the complete Application Programmers Interface (API) for all components on the board, except for IEEE 1394, which will be a subset of the standard. This API will offer a developers logical services like audio, video, graphics, descrambling, etc. Together with this you will get the Feature Demonstration Application (FDS). This is an application that will show you the key features of the system. 6.1.3 DOCUMENTATION In the following way you can interface to the system to develop and debug your own application. Connect a PC (or other development system) with a ROM emulator to extension board on the debug connector, compile the supplied source code and load the executable in the ROM emulator. Connect the RS232 debug port to the PC and run a terminal program, this will give you a debug screen. If you don't have a ROM emulator you can use the parallel port (IEEE 1284) of the Set-Top Box. There is a loader program embedded in the EPROM of the system which allows development without ROM emulator. The maximum possible memory configuration consists of a boot ROM (256 kbytes) with the loader program, 2 Mbytes fast DRAM as scratch memory, 32 kbytes NVM for channel data storage, 4 Mbytes Flash memory to store the program and 4 Mbytes SDRAM video memory. The boot Chip Select can be switched between boot ROM and Flash memory. Of course a smaller configuration is possible, just leave the memory footprints open. Here you will find the user manual and programmers reference for all major parts of the system like the SAA7215 (AVGD chip), the SAA7214 (MPEG2 descrambler demultiplexer chip), and the satellite front-end module (OM5718). 6.1.4 TEST REPORTS These are included to prove the system maturity. You will see the reports of the API tests and the reports concerning the extensive In-System-Test. The latter is done to prove the chip-set in a complete system environment, a customer like set-up, customer use based on our experience with previous end-customers. 1999 May 05 16 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept 6.5 Running `Hello world' OM5721 We have supplied a small program which is called `Hello world' to help you start developing you own software. How can we get the supplied `Hello world' application running if we work with the a PC and a ROM emulator? Connect the emulator to the STB5660 board via the extension board. Then connect the PC RS232 port to the STB5660 RS232 port. The program is running pSOS as the read-time software. You need the pSOS libraries to build the software. Compile the platform layer (drivers), the Board Support Package and the `Hello world' program. Load the executable in the ROM emulator and start the program. You will see the `Hello world' text on the debug window. You are now ready to start writing your own application, with help from the programmers reference documentation and user guide. 1999 May 05 17 Philips Semiconductors Product specification STB5660 (Set-Top Box) STB concept 7 CONTENTS LIST FOR STB5660 Delivery list for the STB5660 system ITEM 1.
