ISMA Tackles Fast Channel Change

SAN FRANCISCO -- Responding to the industry's need for fast IPTV channel changes, ISMA has begun work on a new specification addressing instantaneous and reliable channel tune-in and continues to solicit industry input on the topic. Fast channel change was identified as a vital Quality of Experience issue potentially affecting consumer adoption of IPTV at the recent Summits that ISMA held to discuss the state of open standards in the industry.

Companies that are not currently members of ISMA are invited to participate in the development of the new channel change specification as one-time auditors at the ISMA 23rd Member Forum, to be held Dec. 6 and 7 in Cupertino, Calif., at Apple Computer. Internet Streaming Media Alliance members at the participant level can contribute to the ongoing work prior to the forum through the Alliance's technical committee. The working draft, "Fast Channel Changing in RTP," is now available for free download at the Alliance's Web site, www.ISMA.tv.

"There is a general myth in the industry that RTP channel change is slow and erratic in principle," said Nikolaus Farber of Fraunhofer IIS and the ISMA technical chair. "But with the correct deployment, RTP is one of the most stable and effective technologies for IPTV, including fast and accurate channel tune-in," he said.
