IBM ASPERA STREAMING FOR VIDEO WITH FASPSTREAM FOR NEAR-LIVE AND LIVE VIDEO STREAMING
Live and near-live streaming of broadcast quality video content (10 - 50 Mbps) over IP networks with small start-up delays and glitch-free experiences have traditionally required expensive and specially-provisioned infrastructure. Traditional distribution systems use live satellite feeds from the streaming source or dedicated terrestrial networks with heavy quality of service to ensure low latency and low packet loss rates so as to not degrade the play out quality. In recent years, advances in broadcast quality video compression have also made it possible to distribute lower bit rate versions through web streaming over consumer broadband bandwidths (1-10 Mbps), but even at these bit rates, providers have relied heavily on global content distribution networks (CDNs) to stream the video content from the network edge to the consumer. These CDNs allow the user to take advantage of low round-trip latency and relatively low packet loss rates or a better quality user experience. Note that lower bit rate transcoding does not eliminate the need to ingest a high quality stream to transcoders, which may be remote from the source. DOWNLOAD
