Study of Potential Standardization of Motion Video Teleconferencing Systems Operating at 1.544 MBPS

摘要

The purpose of this effort was to study the feasibility of establishing Federal Standards for digital, color, motion codecs operating a 1.544 Mb/s for use in video teleconferencing systems. The objective of the study was to identify and quantify, where feasible, those parameters which require standardization in order to achieve interoperability and compatibility in digital motion video transmission for teleconferencing systems. The methodology employed in the study included the following key elements: 1. Survey the industry to determine the manufacturers of digital, color, motion codecs operating at 1.544 Mb/s, 2. Solicit information about the codecs from the individual vendors. 3. Tabulate, study, and analyze the data received from the vendors about their products, 4. Compare key characteristics and parameters of the various codecs, and 5. Investigate existing digital, color, motion systems and compare the codec characteristics desired by the Government with those submitted by the vendors.
