Overview: 5D1 H264 Encoder with 4-Channel A/V Decoder & 12 Channels External VD Inputs for Security Applications TW5864B1
TW5864 is a H.264 encoder solution with integrated 4-channel analog A/V decoders. TW5864 can be used as a low cost single chip solution for 4-channel H.264 hardware pression PC cards, or 16-channel cards by using additional external TW2866 chips. There are 3 versions of TW5864 that can support no external video decoder (TW5864A), 4 channel external video decoders (TW5864B), and 12 channel external video decoders (TW5864C). TW5864 can also be used in embedded DVR applications as an AV front-end chip with H264 encoding capability. It can work with existing H.264 hardcore or DSP based CODECs. In existing H264 CODECs, performance may be limited due to limitation in both memory bandwidth and hardware resources. With the H.264 encoder built in at the front-end, the number of encoding channel supported scales with number of TW5864 chips used.
