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.

BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to a virtual channel table for a broadcast protocol and a method of broadcasting using the same.
Discussion of the Related Art Generally a program and system information protocol (hereinafter, referred to PSIP) of an advanced television systems committee (hereinafter, referred to as ATSC) standard for digital television broadcasting contains a virtual channel table (VCT).
The PSIP typically contains an electronic program guide (EPG) and system information (SI). The PSIP is defined as the protocol of the ATSC standard for terrestrial and cable digital television broadcasting, which parses encoded messages by using a moving picture experts group-2 (MPEG-2; ISO/IEC 13818-1) system to thereby provide various kinds of information on the broadcast programs. This ATSC standard is described in "Program and System Information Protocol For Terrestrial Broadcast and Cable", ATSC
Document A/65, 23 DEC 1997.

As mentioned above, since the information on an inactive channel is contained in the. virtual channel table, = the digital television receiver can determine whether the virtual channel currently received is an active channel or an inactive channel by parsing only the virtual channel table. For example, if the value of the program number . 15 field "program number" in the virtual channel table is "0", .if the value of the information on the inactive channel defined by assigning a predetermined bit in the reserved = field is "0", or if the service location descriptor field "service location descriptor" is not contained in the .virtual channel table, the major channel number field "major channel number"= and the minor channel number field "minor channel number" defined in the bit stream syntax of the virtual channel table currently transmitted can be used to determine that the current virtual channel is an inactive =
