In one embodiment, a method comprises receiving a stream of transport packets encapsulating media packets, and generating a reference to the point-of-interest media packet relative to the location of the point-of-interest within the transport packet stream. The reference is generated for each media packet that is identified as a point-of-interest.

In conventional HTTP-based adaptive streaming (HAS), a video source is encoded at multiple levels of constant bitrate representations, and a client makes its representation selections according to the measured network bandwidth. While greatly simplifying adaptation to the varying network conditions, this strategy is not the best for optimizing the...

In recent years, the technology for video delivery over the Internet is shifting towards a new paradigm: HTTP-based adaptive streaming (HAS). An HAS client receives video contents on a segment by segment basis via standard HTTP GET requests. It can dynamically change the rate and quality of the video in the presence of time-varying bandwidth change...

Today, the technology for video streaming over the Internet is converging towards a paradigm named HTTP-based adaptive streaming (HAS). HAS comes with two unique flavors. First, by riding on top of HTTP/TCP, it leverages the network-friendly TCP to achieve firewall/NATS traversal and bandwidth sharing. Second, by pre-encoding and storing the video...

Channel-change times in multicast-based IPTV distribution networks are often slow compared to analog video networks where the channel change is almost instant. One way to overcome these relatively slower channel change is server-based channel-change acceleration based on the rapid acquisition method standardized by the IETF. Concerns about potentia...
