DIGITAL TELEVISION SIGNAL, DIGITAL TELEVISION RECEIVER, AND METHOD OF PROCESSING DIGITAL TELEVISION SIGNAL |
摘要 |
A method of processing a digital television (DTV) signal in a DTV receiver, the method includes receiving 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, wherein the ETT instance further contains a CRC 32 field, demodulating the digital television signal, and identifying at least one pertinent ETT instance from the plurality of ETT instances. |

1. A method of processing a digital television (DTV) signal in a DTV receiver, the method comprising:
receiving 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 private indicator field, wherein the ETT instance further contains a CRC 32 field; demodulating the digital television signal; and identifying at least one pertinent ETT instance from the plurality of ETT instances. |
