发明名称 TRANSMISSION AND RECEPTION OF TELEVISION PROGRAMS AND AN ADDITIONAL DATA SERVICE
摘要 <p>A method and arrangement are disclosed for transmitting television programs via a plurality of channels, and an additional data service, for example, an Electronic Program Guide, via a selected television channel. While processing and displaying the program guide, prior art television receivers cannot continue the reproduction of a currently received TV program because the program is generally transmitted via a different channel. The invention provides a solution to this problem by duplicating a signal component representing, for example, the audio contents of the various television programs in said selected television channel. This allows customers to keep up with the service they were watching before, and to immediately return to the program if something of interest appears to happen. The invention is particularly applicable in Digital Video Broadcast (DVB) systems where each channel can accommodate a plurality of TV programs.</p>
