Abstract
Official abstract text for this publication.
A 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 last section number field indicating a last section number, 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.
