Video stream transmitting method for video surveillance system, involves sending request to store video stream at coordinator node and receiving selected virtual channel number from node, where request comprises identifier of source node

摘要

The method involves sending a request for storing an initial video stream at a coordinator node, where the request comprises an identifier of a source node. A selected virtual channel number is received from the coordinator node. Data packets of the initial video stream are transmitted over the selected virtual channel, where the video stream constitutes a packet header (PH) and a record header (RH) that have an information representing the source node and the type of data to be transmitted. Independent claims are also included for the following: (1) a method for storing a video steam multiplexed over a transmission channel of a communication network (2) a method for reading a video stream among a set of stored and multiplexed video streams (3) a device for transmitting an initial video stream through a communication network (4) a device for storing a video steam multiplexed over a transmission channel of a communication network (5) a device for reading a video stream among a set of stored and multiplexed video streams (6) a data medium readable by a computer system and including computer program instructions for implementing a video steam transmitting method (7) a computer program stored in a data medium and having instructions for implementing a video steam transmitting method.
