Abstract (en)
[origin: EP0238988A2] In this system, an identification byte (DI) is set if one or several transmitted programs are data-reduced in their transmission. If the identification byte (DI) is set, a decoder for data expansion is switched on in the receiver. If there is no decoder, the channel is muted. <IMAGE>
