5D1 H264 Encoder with 4-Channel A/V Decoder and
12 Channel External VD Inputs for Security Applications FN7961
Rev. 1.00
Jan 10, 2012 The 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
compression 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 …
