TW5866 supports up to 9d1 of h.264 video encoding, 8d1 of h.264 video decoding, or 4d1 h.264 full duplex codec. in addition, TW5866 supports motion jpeg encodi ng and video preview through bt. 656 interfaces and pci interfaces. TW5866 can be used in low cost h.264 hardware compression pci card to support either 8 - channel with a single chip, o r 16 - channel with two chips. it can also work with two external tw2866 to support 16 - cif h.264 compression. TW5866 can also be used in embedded dvr applications as an av front - end chip working with display mux capable socs. TW5866 integrates 8 a/v decod ers. it takes 8 cvbs analog inputs fed into eight internal high quality ntsc/pal video decoders . in addition, it has 2 digital bt. 656 / 1120 interfaces, running up to 108 /148.5 mhz, capable of receiving up to 8 d1, 2 720p / 1080i / 1080p hd video sources. when used as d 1 input, the digital interface takes mu lti - channel video signal from external video decoders , such as tw2866 / tw2867. this allows the TW5866 to support a total of 16 d1 video channels. all the sd / hd video streams are fed into h.264 encoder, mjpeg encoder for compression, and to pci interface and digital 656 output interface for preview purpose s . the h.264 decoded stream from the on - chip video decoder is fed through two bt.656 / 1120 playback interfaces to drive the exter nal display p rocessors. the bt. 656 playback interfaces runs up to 108 mhz and is capable of delivering multi - channel byte - interleaving or field/frame interleaving format for total of 8 d1 playback channels . TW5866 supports functions per channel , such as motion detectio n, night detection, and blind detection engine for channel alarm notification. it features triple scalers per channel for each of the h.264 encode, mjpeg, and pci preview paths. each of these scalers is independently configurable. TW5866 also features per channel osds an d motion adaptive de - interlacer . TW5866 supports 8 - channel of motion adaptive 2d de - interlacers and 2d noise reduction. TW5866 integrates a h.264 baseline level 3 compliant encoder capable of performing up to either 9 d1 equivalent video enc oding (225 fps for pal and 270 fps for ntsc), 8 d1 decoding, 17 channel g.726 adpcm hardware audio encoder with one channel for two way audio communication, and one channel adpcm audio decoding. the h.264 video encoder supports dual - bitstream compression f or both local storage and network streams. it also features a motion jpeg encoder for up to 25 frames per second shared among all video channels. TW5866 provides pci interface for external cpu control and bitstream upload. the pci interface runs at 33 or 66 mhz the external cpu can access the internal meta - data associated with each h. 264 channel for video analytic purpose s . analog video decoder 8 cvbs analog inputs fed into 8 sets of video decoder a ccept all ntsc(m/n/4.43) / pal ( b/d/g/h/i/k/l/m/n/60) st andard s with auto detection integrated video anal og anti - aliasing filters and 10 - bit cmos adcs for each video decoder high performance a daptive 4h comb filter s for all ntsc/pal standards if compensation filter for improvement of color demodulation color t ransient improvement (cti) automatic white peak control programmable hue, saturation, contrast, brightness and sharpness proprietary fast video locking system for non - real - time application noise reduction to remove impulse noise digital input ports bt. 656 two bt. 656 port s at up to 108 mhz interfaced with 2 external tw2866s byte - interleaving supports 4 channels multiplexing with each channel of interlaced d1 at 60/50 fps bt. 1120 two bt. 1120 ports to support external hd video sources of 720p / 1080i / 1080p format at 74.25 / 148.5 mhz one cascade input supporting cascade of multiple TW5866 chips. this is pi n shared with one playback port pre - processing per channel triple h igh performance down scaler s of each channel scale independently for h.264 , jpeg and pre view output per channel motion detect or with 16 x 12 cells per channel night / blind detections per channel noise reduction and de - interlacing to convert interlaced video into progressive before compression per channel osd for information overlay single bo x 1 - bit per pixel text 2 - bit per pixel text or mask 12 - bit per pixel bitmap
