Abstract:
A digital television (DTV) receiver includes a receiver to receive a digital television signal including a plurality of extended text table (ETT) instances that appear in transport stream packets with common PID values, the ETT instances having common table ID values, each ETT instance comprising a section header and a message body, the section header containing a table identification (ID) extension field that serves to establish uniqueness of each ETT instance, the message body containing an extended text message (ETM) which provides detailed descriptions of a virtual channel or an event associated with each ETT instance, wherein the section header further contains a protocol version field indicating a protocol version and a section syntax indicator field indicating a section syntax indicator, a demodulator to demodulate the digital television signal and an identifier to identify at least one pertinent ETT instance from the plurality of ETT instances.

Abstract:
A digital television (DTV) signal for use in a DTV receiver includes an extended text table (ETT) which includes a header and a message body. The header includes a table identification extension field which serves to establish uniqueness of the ETT, and the message includes an extended text message (ETM). If the ETT is an event ETT, the table ID extension field includes an event identification which specifies an identification number of an event associated with the ETT. On the other hand, if the ETT is a channel ETT, the table identification extension field includes a source identification which specifies a programming source of a virtual channel associated with the ETT. A section-filtering unit included in the DTV receiver is able to use table identification extension fields of a plurality of ETTs for section-filtering a pertinent event or channel ETT from the ETTs.
