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.
Claims5
A method of processing a digital broadcasting signal in a digital television receiver, comprising:
- demodulating a digital broadcasting signal including program and system information protocol (PSIP) data including a virtual channel table (VCT), and outputting demodulated PSIP data,
- wherein the VCT includes a predefined data field which is set to zero for an inactive channel,
- wherein the 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 broadcasting station without local viewer interaction;
- and
- processing display of the corresponding virtual channel,
- wherein when the virtual channel is currently inactive, the receiver is capable of skipping over the virtual channel while a user is surfing,
- wherein the VCT further includes a table_id field,
- wherein the VCT further includes a version_number field,
- wherein the VCT further includes a short_name field,
- wherein the VCT further includes a program_number field, and
- wherein the PSIP data further includes a System Time Table (STT).
