Digital Distribution of Video

Objective

A growing number of institutions need to distribute video-based information widely and cost-effectively within their organisations. Examples can be found in applications such as teaching, video conferencing and financial trading rooms.

The overall objective of the PROVIDE project was to demonstrate the feasability of distributing text and graphics-based video images in a digital, compressed format using standard local area network technology.
A growing number of institutions need to distribute video based information widely and cost effectively within their organizations. Examples can be found in applications such as teaching, video conferencing and financial trading rooms. The feasibility of distributing text and graphics based video images in a digital, compressed format using standard local area network technology has been demonstrated. In order to implement a cost effective prototype system, it was necessary to research, develop and deliver the following:
assessment of existing data compression algorithms and development of, where necessary, new ones for the encoding and decoding of digitized text and graphics based video images;
the design and development of a versatile image-processing 'engine' capable of implementing the selected encoding/decoding algorithms;
integration of the resulting components into a prototype systems and achievement of real time video distribution with minimal image degradation and acceptable encoding/decoding delay within the data rate which a local area network (LAN) environment can support.
