Abstract
A virtual channel table for broadcasting protocol and a method for broadcasting by using the virtual channel table includes identification information identifying and permitting discrimination of active and inactive channels contained in the virtual channel table. At a receiver, the virtual channel table transmitted from the transmitting side is parsed, thereby determining whether the current received channel is an active or inactive channel.

A digital television (DTV) receiver, comprising:
- receiving means for receiving a digital broadcast signal including a virtual channel table, the virtual channel table including identification information identifying a channel as being one of an active and an inactive channel;
- a section filter for detecting the identification information in the virtual channel table and providing an output indicating whether the channel is the inactive channel;
- and
- a user interface module for receiving the output of the section filter and controlling display of the channel when the channel is selected by the user and the channel is determined to be inactive,
- wherein said inactive channel is a channel that is not presently carrying a broadcast program;
- however, the same inactive channel is scheduled to carry a broadcast program at a predetermined later time from a broadcast station without local viewer interaction.
