A method is described for streaming video data within a network, wherein the video data includes a sequence of frames. The method includes encoding the sequence of frames and generating a plurality of substreams from the encoded frames in this embodiment. Each of the plurality of substreams is assigned an identifier, and each substream includes a common encoded frame and a non-overlapping portion of the encoded sequence. The non-overlapping portion of the encoded sequence of each substream is selected from the encoded frames based on the identifier of the respective substream. The method also includes transmitting the plurality of substreams to a receiver in an embodiment.

Distributed transcoding of video frames for transmission in a communication network

A system for enabling streaming video to a mobile client includes a plurality of fixed node peers linked to the mobile client via one or more networks as well as a video source linked to fixed node peers and configured to provide streaming video data representing a video presentation to each of the fixed node peers. A decoder assembly associated with each of the fixed node peers is configured to decode the streaming video data and to transcode a portion of the decoded streaming video data for transmission to the mobile client. A video substream manager and interleaver on the mobile client is provided for receiving the transcoded output of the decoder assemblies of the fixed node peers and reconstructing the video presentation on a screen of the mobile client.

Enhanced video streaming to mobile clients

A method for streaming audio data in a network, the audio data having a sequence of samples, includes encoding the sequence of samples into a plurality of coded base bitstreams, generating a plurality of enhancement streams, and transmitting the coded base bitstreams and the enhancement bitstreams to a receiver for decoding. Each of the enhancement bitstreams is generated from one of a plurality of non-overlapping portions of the sequence of samples.

Method and system for distributed audio transcoding in peer-to-peer systems

Distributed cache algorithms and system for time-shifted, and live, peer-to-peer video streaming

Packet-based delivery of video content is facilitated using a peer-to-peer network. According to an example embodiment of the present invention, a packet-based video stream is passed over a peer-to-peer network, with the packets in the stream scheduled and delivered in accordance with a priority assigned to the packets; this priority is based upon a determined or estimated effect that the packet will have upon video quality at a recipient peer. In some applications, the packets are temporally spaced to mitigate congestion and/or distortion of video associated with congestion in the delivery of the packets.

Video communications in a peer-to-peer network

The embodiments of the invention relate to application-layer multicasting, particularly to reduction of join/attachment latency of a node when joining a multicast group, by providing to a joining node a flat peer list and a preferred peer list which contains candidate node entries with recent available bandwidth information.
