Abstract
A digital broadcast sending/receiving system includes a digital broadcast sending apparatus and a digital broadcast receiving apparatus. The digital broadcast sending apparatus multiplexes the audio data and video data of a broadcast program into the transport stream together with preselection control information which controls preselection information image facilitating program preselection, and sends the transport stream to the digital broadcast receiving apparatus. On receiving the transport stream, the digital broadcast receiving apparatus extracts the preselection control information, and reproduces a preselection screen on a display in which the preselection information image is superimposed on the video image of the broadcast program. The digital broadcast receiving apparatus receives from the viewer specification of a program to be preselected. The digital broadcast receiving apparatus stores information on the preselected program, and reproduces the preselected program in accordance with the stored information.
