摘要:
A multimedia-on-demand peer-to-peer device acting as a receiving peer includes a local cache memory device adapted to store a multimedia prefix. Local storage of the multimedia prefix allows rapid commencement of playback of the requested multimedia program without substantially loading the streaming capacity of an associated server device. The storage of multimedia prefixes in local cache memory of the receiving peer device can take place during periods of relatively low network loading so as to optimize network and server scheduling. Included is a method and apparatus for performing admission control in a peer-to-peer multimedia-on-demand system. The admission control system determines if there is sufficient system capacity to support a new request from a peer-to-peer device acting as a client in light of the presence of stored multimedia prefixes at the peer-to-peer device acting as a receiving peer device, among other factors.

A method is described including receiving a streamed leading content sub-clip, determining a set of needed content sub-clips, locating one of the set of needed content sub-clips and downloading the located content sub-clip. A system for providing content-on-demand is described having a peer, a server and a tracker. The tracker may be co-located with the server. The peer includes means for receiving a streamed leading content sub-clip, means for determining a set of needed content sub-clips, means for locating one of the set of needed content sub-clips and means for downloading the located content sub-clip.

A method and apparatus are described comprising detecting a playback operation, determining a target playback point for the playback operation and detecting a sub-clip type into which the target playback point falls. The method and apparatus also receive a streamed leading sub-clip, determine a set of needed sub-clips, locate one of the set of needed sub-clips and download the located sub-clip.
摘要:
In one embodiment of the present invention, a method includes locating at least one transmitter on at least one movable camera for transmitting a signal detectable by receivers located in fixed positions for distance measurements of the camera with respect to the receivers for location processing of the distance measurements. The method can further include detecting out of range measurements from collected range measurements based on receivers in known locations as an indication of the movement of a transmitter responsive to signals from the transmitter.

摘要:
A method and apparatus for performing admission control in a peer-to-peer video-on-demand system are described including determining if there is sufficient bandwidth to support leading sub-clip streaming for a new request from a video playback device, determining if there is sufficient bandwidth to admit the request without sacrificing quality of service for existing requests, accepting admission of the new request if both determining acts are positive and rejecting admission of the new request if either of the determining acts are negative. Also described is an apparatus for providing content to a video playback device in a peer-to-peer video-on-demand system including an admission control unit and a data engine component.
