摘要

The present invention relates to a device for receiving a multiplexed stream specified by the DVB-SI standard comprising at least one main stream comprising a first PAT table identifying at least one first PMT table containing at least the list of elementary streams of an audiovisual service currently being broadcast and intended to be reproduced in real time. The device determines in the content of the first PMT table a descriptor listing identifiers of elementary streams constituting a secondary stream. The secondary stream transmits at least one audiovisual document in PUSH mode without any time constraint. The device receives the audiovisual document by using the data included in the descriptor and records it so as to reproduce it later. The present invention also relates to the method of generating the multiplexed stream and the devices able to implement the method.
