ABSTRACT:
A digital television (DTV) receiver and a decoding method are discussed. According to an embodiment, the DTV receiver includes: a receiving unit for receiving a digital broadcasting signal including a plurality of extended text tables (ETTs) that appear in transport stream packets having common PID values, each ETT comprising a section header and a message body, wherein the section header contains a table identification extension field that serves to establish uniqueness of each ETT, and wherein the message body includes an extended text message (ETM) which provides detailed descriptions of a virtual channel or an event associated with each ETT; and a program and system information protocol (PSIP) decoder for detecting the table identification extension field to determine uniqueness of each ETT and detecting at least one pertinent ETT from the plurality of ETTs using the determined uniqueness of each ETT.
