摘要:
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.
