Video Compression That's Future Proof
|09 февраля 2009|
The ability to reduce video bandwidth needs has become critical as the demand for video skyrockets among consumers and businesses alike. A new study from TNS and the Conference Board shows that, since 2006, the number of U.S. households watching TV programming online has nearly doubled.A front page New York Times story warns of the threat posed by “video road hogs” which are jamming up the Internet by users uploading and downloading videos. At the same time, traditional TV viewing has not decreased; rather, users are demanding more and higher-quality content. In 2007, Stan Schatt of ABI Research, a leading broadcast industry research firm, warned, “Cable providers are going to get killed on bandwidth as HD programming becomes more commonplace.” All media delivery platforms, whether satellite, broadcast TV, IPTV, Internet video, and wireless all face the same challenge: lack of video bandwidth.
Broadcast International has developed CodecSys video compression technology to break the video bandwidth barrier. CodecSys is a family of ultra-high performance, video compression solutions, built on the industry’s first “future-proof” open software architecture. The CodecSys software suite ranges from market-specific solutions, such as H.264 encoding for the IPTV and Internet video markets, to the industry’s first Video Operating System (VOS), supporting multiple codecs and providing advanced transcoding capabilities for video re-purposing and media management.
The bandwidth crisis will be particularly severe in the U.S., which has dropped from fourth to 15th place on the broadband ranking maintained by the Organization for Economic Cooperation and Development. Michael Kleeman, a senior fellow at the Annenberg Center for Communication at the University of Sourthern California, has cited video compression as a technology critical to the resolution of the bandwidth crisis.
There is no question that better video compression technology would take the pressure off the Internet — especially as more and more users want to upload video to sites like YouTube and MySpace, in order to share experiences. At present, many content providers are forced to use proprietary streaming solutions that do not solve the fundamental problems associated with Internet video and thus have unsatisfactory quality. IP networks impose packet loss on data, which can severely impede the quality of a compressed video and audio stream with interdependencies and can impair sound synchronization.
Most current solutions offer only a 25 percent reduction in bandwidth at best, with compromised picture quality. Even new fiber initiatives such as those from Verizon and AT&T will be challenged to deliver the quantity and quality users are going to demand.
