Multichannel H.264 Audio/Video Codec
TW2819
Features
TW2819 is a high performance and cost effective
multi-channel H.264 codec solution designed for
the security surveillance market. It is capable of
receiving and encoding maximum 16 channels
standard definition (SD) or 960H (WD) video. It
can also support up to 8 channel high definition
(HD) 720p or 4 channel 1080p encode. It supports
D1/WD1/720p/1080p decode also up to 4
channels. Each video channel can be
independently controlled in terms of encode/
decode mode, frame rate, bit rate, and resolution.
