Embodiment Construction

[0012] Aspects of the invention provide a method of bandwidth saving using social networking in a VOD system. In an embodiment, the VOD server system is capable of proactively delivering VOD content items to requesting users as well as social networking friends of users sharing common distribution nodes. In such an embodiment, VOD content items can be multicast, and no additional access network resources are required for this purpose, thereby saving significant system bandwidth, reducing load on the access network, and facilitating more efficient use of system resources .

[0013] Thus, aspects of the invention can improve customer satisfaction in situations where a customer knows his friend is watching a movie and decides to go see the same movie. In a conventional VOD system, the movie must then be requested from the VOD server, which in turn requires finding out the bandwidth required to serve the client, which may involve significant delays and, depending on the current l...

Abstract

A method for using social networking information in a video on demand (VOD) system operated by a server provider to save bandwidth is disclosed. In the VOD server system, a request for a VOD content item is accepted from a first client system associated with a user of the VOD system. Gets a list of the user's social network friends. A node sharing group that determines a list of social network friends. The node sharing group includes the first client system and zero or more client systems sharing the distribution nodes of the VOD server system with the first client system. A video delivery start message is sent by the shared distribution node to each client system in the shared group of nodes.

Description

Background technique [0001] Video on Demand (VOD) generally refers to technology that allows a client device end user to select video content or other content from a source, such as a central server, for viewing on an appropriate end user display device such as a television (TV) or computer monitor field. One type of VOD system is a "streaming" VOD system in which video content or other content is streamed from a source to an end-user client device, and once the content is streamed from the source to the end-user client device through an appropriate network connection, the Browse to get started. Another type of VOD system is a "download" VOD system in which the content is initially downloaded to a video processing device such as a set-top box before end-user viewing begins. In general, almost all download VOD systems and many streaming VOD systems allow the end user to pause, fast forward and rewind the content, as well as browse the content at any time. [0002] A VOD serv...
