Techwell 9D1 H.264 CODEC with 8-Channel A/V Decoder TW5866 TW5866 is a H.264 CODEC solution with integrated 8-channel analog A/V decoders. 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 encoding 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, or 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 decoders. 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 MHz, capable of receiving up to 8 D1, 2 720P / 1080i / 1080p HD video sources. When used as D1 input, the digital interface takes multi-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 purposes. The H.264 decoded stream from the on-chip video decoder is fed through two BT.656 / 1120 playback interfaces to drive the external display processors. The BT.656 playback interfaces runs up to 108 MHz and is capable of delivering multi-channel byteinterleaving or field/frame interleaving format for total of 8 D1 playback channels. TW5866 supports functions per channel, such as motion detection, 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 and motion adaptive de-interlacer. TW5866 supports 8-channel of motion adaptive 2D de-interlacers and 2D noise reduction.

The H.264 video encoder supports dual-bitstream compression for 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.
