An apparatus and a method for transferring an audio/video/data service from a transmission end to a reception end over a radio interface. The audio/video/data service includes one of audio information, video information and data. The radio interface includes a plurality of subchannels and a plurality of carriers for transmitting the audio/video/data service and at least one information channel. The audio/video/data service is divided into a set of files, wherein the set of files forms a service ensemble. A parameter group is associated with and describes each corresponding one of the files. Each of the files, along with a corresponding parameter group is placed onto one of the subchannels. A placement indicator and a corresponding parameter group is placed on the at least one information channel. The subchannels and the at least one information channel are multiplexed into a plurality of transmission frames which are digitally modulated for transmission to the reception end over the radio interface using the plurality of carriers. The reception end receives the plurality of carriers and demodulates, from the carriers, the transmission frames, separating the subchannels and the at least one information channel. Information received from the at least one information channel is used for separating the parameter groups from the subchannels. The parameter groups are used for forming a selective service by combining and processing substantially only desired files.

[ I claim:] [1.] A method for transferring an audio/video/data service comprising at least one of audio information, video information and data from a transmission end to a reception end over a radio interface comprising a plurality of subchannels and a plurality of carriers for transmitting said audio/video/data service and at least one information channel,said method comprising, at said transmission end:dividing said audio/video/data service into a set of files, each file of said set of files containing audio/video/data information, wherein said set forms a service ensemble, and associating with each of said files a parameter group for describing each of said files;placing each of said files onto a corresponding one of said subchannels, placing a corresponding parameter group onto said corresponding one of said subchannels and placing an indication concerning placement of each of said files and said corresponding parameter group onto said at least one information channel;multiplexing at least said subchannels and said information channel into a plurality of transmission frames which are digitally modulated; andsending said digitally modulated transmission frames to said reception end over a radio interface using multiple carriers;said method further comprising, at said reception end:receiving said multiple carriers, demodulating from said multiple carriers, said plurality of transmission frames and separating, from said transmission frames, at least said subchannels and said at least one information channel;using information received from said at least one information channel for separating said parameter groups from said subchannels; andusing said parameter groups for forming a selective service by combining and processing substantially only desired ones of said files, whereby ones of said files not needed for selective service will not be further processed.
