Introduction
The VCX-2400-E and VCX-2400-D are the chassis versions of the Core Tec stand-alone VCX-
2400 MPEG-2 IP product series. These units are fully compatible with the “-R” card cage versions of the
product series.
The VCX-2400 Digital Video Codec system consists of a video encoder/decoder pair providing
the capability for one-way end-end transmission of compressed digital video in IP packets at data rates in
the 1.2 to 6.0 Mbps range.
The system employs MPEG-2 MPEG2 standard ISO/IEC 13818-2 (ITU-T H.262) encoding. The
encoding-decoding process is applied to an NTSC (or PAL) video input, selected in software.
The video encoder converts the analog video to a serial digital 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 of video format and resolution, data sub-channel characteristics, and basic IP
parameters is achieved through one of the following means:
a) A Terminal Program
b) Telnet through the Ethernet connection
c) Core Tec Watchdog software
d) Web Interface (only available for VCX-2400-E)
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.
