Multichannel H.264 Audio/Video Codec
TW2819
The 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
(WD1) video. It can also support up to 8-channel high definition
(HD) 720p or 4-channel 1080p encode. It supports
D1/960H/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.
Applications
