Hardware trials for verifying recommendation H.261 on p × 64 kbit/s video codec

摘要

ISDN deployment around the world is providing a good opportunity for realizing the long awaited visual telephone service. A worldwide unique video coding standard plays another essential role in achieving that goal. This paper highlights the hardware trials and their results which verified the recently established draft Recommendation H.261 for the sub-primary rate (64 kbit/s-2 Mbit/s) video coding. These trials were succesfully conducted in and among several countries using Flexible Hardware which is a test bed for verification and the optimized CCITT specifications.
