摘要： 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.

摘要： At least one camera station (1, 2), which is usually mobile, is provided in order to generate television picture signals. These picture signals are coded in coded digital form so as to produce a coded digital signal at output (62) whose bit rate can be selectively varied. The camera station (1) is associated with at least one mobile telephony channel (41, 42, ... , 4n) which can be selectively activated in order to provide a transmission capacity which is available at that moment. The coded signal is transmitted, selectively adapting its bit rate to the transmission capacity available at that moment. The number of mobile telephony channels (41, 42, ... , 4n) that can be activated can also be selectively increased in order to increase available transmission capacity.
