Using the VideoEdge IP Encoder with Intellex IP

This application note explains the tradeoffs inherent in using IP video and

provides guidance on optimal configuration of the VideoEdge IP encoder with

Intellex IP. The VideoEdge IP Encoder is a high performance video encoder

capable of serving multiple video streams at 4CIF resolution and up to 30 images

per second per stream. The VideoEdge IP Encoder is the first video encoder

using American Dynamics Active Content Compression (ACC) that is compatible

with the Intellex IP Digital Video Management System. The new combination of

Intellex IP, Network Client and VideoEdge IP Encoder provides a powerful new

solution for security applications.

IP Video Basics

IP video uses Ethernet to transmit the video information from the IP encoder (or

IP camera) and the Intellex IP unit. To accomplish this, first the analog video

signal is digitized in the encoder and then compressed using the ACC

compression algorithm. The VideoEdge IP uses a Digital Signal Processor (DSP)

to perform the compression and network functions. Once the image data is

compressed it is treated just like any other digital information on the network and

is transported across the network using the TCP-IP protocol. Once it is received

by the Intellex IP the digital video information is decompressed (so that it can be

displayed live locally or with Network Client) and then selected frames are

recompressed for storage. One new capability available with the VideoEdge IP

Encoder is that the live image display rate can be different than the image record

rate. The live rate is configured on the IP Sources setup screen in Intellex IP and

the record rate is set up on the Rate setup screen on the Intellex IP. The record

rate is limited to be less than or equal to the live rate. Compressing and

decompressing the digital video is a significant load on the DSP in the encoder

and the CPU in the Intellex IP.
