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 108/148.5 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 byte-
interleaving 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.
TW5866 integrates a H.264 baseline level 3 compliant
encoder capable of performing up to either 9 D1 equivalent
video encoding (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 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. 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 purposes.
Analog Video Decoder

accept all NTSC(M/N/4.43) / PAL
(B/D/G/H/I/K/L/M/N/60) standards with auto detection
