| DVXPLORE CODEC DVD-QUALITY VIDEO RECORDING AND PLAYBACK FOR CONSUMER PCS KEY FEATURES The DVXPLORETM codec from C-Cube Microsystems is the industry's first single-chip MPEG-2 and DV consumer codec, delivering DVD-quality video recording and playback for consumer applications. The DVXPLORE codec enables exciting new content creation and PC/TV applications for the home, based on DVDquality video recording. For the first time, PC manufacturers can offer consumers DVD-quality video recording and frame-accurate MPEG-2 editing, turning PCs into complete DVD recording and content creation stations. Manufacturers can incorporate sophisticated digital video recording features, such as automatic television program recording using an electronic program guide (EPG), into consumer PC/TV products. Digital recorder applications can provide time-shifting capabilities such as instant replays of broadcast programs. As a result, manufacturers and applications developers can use the codec to establish DVD-quality (MPEG-2) video as a standard data type on consumer PC and PC/TV platforms. The DVXPLORE codec leverages C-Cube's highly flexible DVx video compression and decompression architecture to provide an unprecedented range of capabilities that aren't limited to a single video format. PC users can acquire video from analog, DV, or MPEG sources and edit it with frame accuracy to create MPEG-2 videos that play back on any MPEG-2 or DVD decoder. Employing MPEG-2 compression, users can extend recording time tenfold compared to Motion JPEG (M-JPEG) or DV solutions. They can also use the codec to address low-bandwidth applications such as MPEG-1 video for websites and email. SIX KEY FUNCTIONS ON ONE CHIP The versatile DVXPLORE codec provides these six key functions: * MPEG-2 Encoding: PCs can record DVD-quality video using C-Cube's advanced, highly reliable PerfectViewTM encoding algorithm. * Dual-Stream MPEG-2 Decoding: Two MPEG-2 data streams can be decoded simultaneously to provide frameaccurate editing of MPEG-2 video. Hardware rendering of special effects (fades, wipes, or dissolves) enables realtime preview of the edited video. * Realtime DV to MPEG-2 Transcoding: Users can convert digital video from consumer DV camcorders to MPEG-2 video, enabling playback on any MPEG-2 or DVD decoder. The all digital conversion process delivers DVD quality while minimizing the storage requirements for captured video. * DVD Decoding: Hardware DVD video decoding provides the highest video quality with minimal host CPU requirements. The DVXPLORE codec performs full decoding of CSS-encrypted MPEG-2 video and subpicture streams. * MPEG-1 Encoding: Users can take advantage of MPEG-1 video capture for low-bandwidth Internet and intranet video applications such as live "webcams," video clips on websites, and video email attachments. * Single Stream DV Codec: The DVXPLORE codec also allows users to capture and edit video in native DV format. In conjunction with a software AC-3 decoder running on the host processor, The DVXPLORE codec provides C-Cube's market-tested DVD playback feature set: MPEG-2 decoding, subpicture decoding, PCM audio, A/V synchronization, and SecureViewTM CSS copy protection. CONSUMER VIDEO EDITING With the DVXPLORE codec, personal video content creators get WYSIWYG ("what you see is what you get") simplicity. Hardware acceleration for dual-stream decoding and video postprocessing lets users perform seamless MPEG editing in realtime using C-Cube's revolutionary FAMETM (Frame Accurate MPEG Editing) technology. FAME allows users to implement special effects on the fly, and accomplish A/B roll transitions across frames such as fades and dissolves. Because the DVXPLORE codec records and edits the video in MPEG-2 format, all files can easily be stored on an ATAPI hard disk. KEY FEATURES AND BENEFITS DVD-QUALITY VIDEO The DVXPLORE codec delivers MPEG-2 video to consumer PCs, allowing full-screen DVD-quality video recording and playback at consumer prices. The codec runs downloadable microcode that lets it operate as both a DVD-quality digital video recorder (encoding) and player (decoding). C-Cube's patented PerfectView encoding algorithm produces superior images using a number of techniques--including multilayer motion estimation, variable bit-rate encoding, inverse telecine, and optimal bit allocation--that work together to improve encoding efficiency and picture quality. DV VIDEO CAPTURE AND TRANSCODING The DVXPLORE codec is a forward-looking solution that supports DV-format digital camcorders as well as conventional analog camcorders. This feature is especially desirable as consumers increasingly turn to digital video cameras and consumer PCs come equipped with an IEEE 1394 "Firewire" interface. The DV to MPEG-2 transcoding capability creates video files that are playable on any MPEG-2 or DVD decoder. Transcoding also saves disk space by increasing compression 5 to 10 times.

In addition, PC and set-top hybrids will be able to offer DVD-quality video recording, authoring, and storage in one box. EASY PC INTEGRATION The DVXPLORE codec's PCI bus interface allows easy integration with PCs. It takes advantage of bus mastering to minimize CPU utilization and maximize bus throughput. The codec also supports output of uncompressed video to a dedicated PC video port for display on the PC's monitor. The highly compressed MPEG video streams (2 to 10 Mbps) created by the codec can easily be transferred to and from standard PC ATAPI hard disk drives, eliminating the need for expensive SCSI hard disk drives. Personal Content Creation with DVXPLORE INTERNET-READY VIDEOS The codec's MPEG encoding capability creates MPEG-1 videos that are perfect for low-bandwidth Internet and intranet applications. For example, users can go beyond banners and still photos to create video content for a website, including live "webcam" images. They can also use video email software to add life to their mail attachments. TARGET APPLICATIONS The DVXPLORE codec makes it possible to record, edit, author, and archive DVD-quality video on the PC. It enables a wide range of end-user applications, including: * Intelligent TV applications with high-quality smartrecording * Digital VCRs with timeshifting * Consumer video editing * DVD playback * Personal content creation * Internet/intranet video creation * Video email INTELLIGENTTV APPLICATIONS With a DVXPLORE codec on board, PC/TV products have the power to deliver a wide range of video recording and interactive viewing options. For instance, viewers can: * Automatically record TV shows by selecting items on an electronic program guide * Use time-shifting features such as realtime rewind, pause, and fast-forward to manipulate live broadcasts * Simultaneously access the Internet while recording or viewing a program * Interact with broadcast TV programs and conduct searches in the same way they can interact with a program on a DVD disc * Make use of an application that monitors closed-caption material in the Vertical Blanking Interval (VBI) for key words that will automatically trigger recording TV Tuner NTSC Decoder 8MB EXTENDED RECORDING TIME DVXPLORE variable bit-rate (VBR) technology lets users record hours of DVD-quality video on DVD-RAM, PC hard disks, or other media. For example, users can store up to one hour of video per gigabyte of storage capacity. This makes high-quality video recording economical and practical on consumer PCs.
