摘要:
A method of responding to requests using stream processing can include receiving a server request from a server, wherein the server is configured to generate the server request responsive to a client request, and generating a request identifier associated with the server request. The method can include, responsive to the server request, sending a stream processing request derived from the server request to a first stream processing node. The stream processing request can include the request identifier. Responsive to receiving a create response message including a stream processing result and the request identifier from a second stream processing node, the stream processing result can be correlated with the server request. A write response message specifying the stream processing result can be sent to the server.

A network node is provided for use with a broadband data provider facility, and the first and second subscriber groups, the broadband data provider facility being operable to provide first and second service group provider data. The network node includes a network access device and a downstream configuration component. The network access device converts the first and second service group provider data into first and second service group network access data, respectively. The downstream configuration component receives a configuration instruction, the first and second service group network access data and, based on the configuration instruction, provides the first service group network access data to the first subscriber group and the second service group network access data to the second subscriber group. The downstream configuration component further receives a second configuration instruction and, based on the second configuration instruction, provides the first service group network access data to the first and second subscriber groups.

摘要:
A transcoder (110) for transcoding a basic representation of a videostream into one or more arbitrary representations is disclosed. The transcoder comprises: a receiver (112) adapted for receiving the basic representation and at least one frame information set comprising one or more frame information packets; a decoder (114) adapted for decoding the basic representation; a re-encoder (116) adapted for selecting at least one frame information set and for selecting one or more frame information packets from this at least one frame information set for forming an arbitrary representation. The re-encoder is adapted for extracting coding information from the frame information packets, and for re-encoding the decoded basic representation using the coding information thereby obtaining the one or more arbitrary representations.
