摘要： An implementation is described herein, which facilitates a fast channel change by receiving and decoding a unicast acquisition media stream that corresponds to a soon-to-be-requested target multicast media stream. It does this before requesting the target multicast media stream of the new channel. Once the transmission of the unicast stream is caught up with the multicast stream, this implementation splices from the unicast acquisition stream to the target multicast media stream.

摘要： Described herein is a technology facilitating the presentation of digital video streams. An implementation, described herein, reduces the effective start-up delay in the presentation of the first frames of the video content that occurs when a system tunes into a video stream by streaming at least an additional stream parallel with the main multicast stream. The alternative parallel stream having offset start points from the main multicast stream to more quickly provide a picture in response to a tuning command. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

摘要： Media data is distributed across multiple devices and is locatable using a hashing function and a hash table. The media data is partially replicated based on popularity thereof. In a described implementation, a media data block is locatable by hashing a media data indicator to produce a media data hash value that maps to a bin of the hash table. The bin is associated with at least one device that stores and/or with a sender that is capable of sending to clients the media data blocks mapping thereto. Each bin may have primary and secondary roles. Devices holding primary roles store all of the media data blocks mapping to a bin. Devices holding secondary roles replicate the media data blocks mapping to the bin that are also within a top predetermined popularity percentage. Popularity is determined based on numbers of clients currently requesting a particular media data portion.

摘要： Media data is distributed across multiple devices, and decentralized media data dissemination architecture is formed. Multiple respective senders are associated with multiple respective distributed portions of the media data. Multiple schedulers are associated with clients and are capable of scheduling the sending of media data thereto. Schedulers formulate send requests that stipulate particular media data portions and designate destination clients. These send requests are transmitted to the multiple senders in accordance with the associated respective distributed portions in conjunction with the stipulated particular media data portion of each send request. The senders are capable of sending the stipulated particular media data portions of the send requests to the designated destination clients without routing through the schedulers. In a described implementation, a sender and a scheduler are present on each device of the multiple devices.
