Method for transmitting information stream corresponding transmission system transmitter receiver and computer product
First Claim
1. Method for transmitting on a set of communication channels (Cj) at least an information stream (V, A, D) assembled in access units (Vtn, Atn, Dtn) with associated respective meta-information, characterised in that for the transmission of said set of channels (Cj) said at least one information stream (V, A, D) is arranged in packets, each packet comprising at least a segment of one of said access units (Vtn, Atn, Dtn) of said at least one information stream (V, A, D) and a header (H);
- said header (H) comprising;
a first set of fields (HS), which represents the meta-information associated to said at least one segment of said access unit (Vtn, Atn, Dtn) of said at least one information stream (V, A, D), and a second set of fields (HG) comprising general validity fields, independent from said at least one information stream (V, A, D).

Abstract
An information stream with video (V), audio (A) and data (D) components assembled in access units (Vtn, Atn, Dtn) with associated respective meta-information is transmitted on a set of communication channels (Cj), such as different lines of a mobile communication network. The stream is arranged in packets each of which contains at least a segment of access unit and a header (H). The header (H) in question comprises a first set of fields (HS), which represents the meta-information associated to the related access unit(s), and a second set of fields (HG), comprising general validity fields, independent from the information stream. Typically, these are fields that convey the following information: number (PN) of the packet in the order of transmission, identifier (CH) of the channel that carries a particular stream, length (L) of the data packet as well as check, for instance of the checksum type (CK). Preferably, the latter field is related to all the data of the header (H), except the check field itself.
