Introduction
The VCX-4400-E and the -ER are the chassis versions of the Core Tec stand-alone VCX-
4400 MPEG-4 IP product series. These units are fully compatible with the “-ER” card cage
versions of the product series.
The VCX-4400 Digital Video Codec system consists of a video encoder and a Core Tec
decoder pair providing the capability for one-way end-end transmission of compressed digital
video in IP packets at data rates in the 64kbps to 3.5 Mbps range.
The system employs MPEG-4 encoding. The encoding-decoding process is applied to an
NTSC (or PAL) video input, selected in software.
The video encoder converts the video to a serial signal, which is multiplexed with any
data sub-channels present. The stream is then formatted into a series of IP packets sent to the
network through a standard Ethernet connection.
Modification to video format and resolution, data sub-channel characteristics, and basic
IP parameters are achieved through one of the following means:
a)
a Hyper Terminal accessible menu
b)
Telnet through the Ethernet connection
c)
Watchdog CCS
The video decoder receives the IP packets, separates the video data from the data sub-
channels, and converts the video data to analog form, providing an NTSC (or PAL) output.
The units feature two bi-directional data sub-channels (programmable for RS-232 or RS-
422). Data bits are multiplexed with the digital data stream.
