ABSTRACT:
A broadcast signal includes an information table (EIT) or an application information table (AIT) which includes a descriptor. The descriptor includes image data representative of a thumbnail image to be displayed within an electronic program guide (EPG). A decoder decodes the EIT or AIT from a broadcast signal, and an application manager displays the thumbnail image within an EPG to indicate that a channel scheduled to carry a broadcast program is also scheduled to carry broadcast data simultaneously.
