摘要： A technique for managing the streaming of digital video content to multiple clients involves identifying an attribute of a content element that is streamed to a client and selecting a protection mechanism for the content element as a function of the attribute, wherein the protection mechanism enables streaming of the content element to the clients in the event of a resource failure. In an example, the identified attribute is an indication of the popularity of the content element (e.g., as measured by the number of active streams), such that the protection mechanism is selected as a function of the popularity of the content element. In an embodiment, protection mechanisms that offer a higher level of protection are selected for the more popular content elements and protection mechanisms that offer a lower level of protection are selected for the less popular content elements.

摘要： A technique for streaming digital video content to multiple clients involves establishing a logical group of IP-connected stream servers, generating state information at multiple stream servers within the logical group, sharing the state information amongst stream servers in the logical group, and using the shared state information to respond to resource failures within the logical group. By sharing state information within the logical group of stream servers, stream servers with the shared state information can quickly take over the active streams from a failed stream server within the logical group. The quick transition of responsibility from one stream server to another enables the streaming network to provide continuous streaming of digital video content to the viewer without interruption.

摘要： A technique for transitioning streamed digital video content between stream servers involves identifying a transition identifier that indicates a point at which streaming of the digital video content transitions from a first stream server to a second stream server and then transitioning the streaming from the first stream server the second stream server at a point in the digital video content that corresponds to the transition identifier. For example, the first stream server stops streaming the digital video content at a point in the digital video content that corresponds to the transition identifier and the second stream server starts streaming the digital video content at a point in the digital video content that corresponds to the transition identifier.

摘要： In one embodiment, a network device analyzes an encoded stream to identify a timing value included in a packet before a splice point. Next, the device determines a difference between identified timing value and a timing value included in a packet of the encoded segment to be spliced. In conjunction with splicing, the network device formats timing values of packets according to the determined difference, which improves play out of the spliced stream.
