Abstract:
A method of formatting a signal for broadcast transmission to remote receivers comprising the steps of:receiving a service comprising at least a first service component and a second service component each selected from the group consisting of audio, data, static images, dynamic images, paging signals, text, messages and panographic symbols; andgenerating a broadcast channel bit stream frame by appending a service control header to said service to dynamically control reception of said service at said remote receivers, said service control header comprising service control data, said service comprising an overall bit rate of K bits per second, said overall bit rate corresponding to n multiples of a minimum bit rate of L bits per second, said frame having a period of M seconds, said service having n.times.L.times.M=n.times.P bits per frame, said frame comprising n.times.P bits for said service and n.times.Q bits for said service control header, wherein K, n, L, M, P and Q are numerical values, respectively;providing said service control header with first service component control data for dynamically controlling the reception of said first service component at said remote receivers; andproviding said service control header with second service component control data for dynamically controlling reception of said second service component at said remote receivers;wherein at least one of said first service component control data and said second service component control data comprises at least one of a plurality of fields comprising a service component length field, a service component type field, an encryption field, a program type field and a language field, wherein said service component length field indicates the bit rate of the corresponding one of said first service component and said second service component, said service component type field indicates which of a plurality of signals is contained in the corresponding one of said first service component and said second service component, said encryption field indicates which of a plurality of encryption methods is used to encrypt the corresponding one of said first service component and said second service component, said program type field indicates which of a plurality of programs is transmitted via the corresponding one of said first service component and said second service component, and said language field indicates in which of a plurality of languages the corresponding one of said first service component and said second service component is generated.
