Abstract
A method for identifying extender text tables of an electronic program guide in a DTV is disclosed. In the present invention, the extender text tables are identified by processing an ETT section in the same manner as other tables using a value capable of identifying the extender text table sections. Particularly, an event_id is input in a table_id_extension within ETT sections, so that the ETT sections can be identified at a receiving or a transmitting party without parsing the ETT sections.
Claims19
A method of processing a broadcast signal in a digital television (DTV) receiver, the method comprising:
- receiving a broadcast signal comprising a plurality of extended text tables (ETTs) that appear in transport stream packets having common PID values, wherein each ETT comprises a section header containing a table identification (ID) extension field which serves to establish uniqueness of each ETT, wherein each ETT further includes a message body containing an extended text message (ETM) which provides detailed descriptions of a virtual channel or an event associated with each ETT;
- and
- detecting at least one pertinent ETT by section-filtering the plurality of ETTs using the table ID extension field included in the section header of each ETT.
A digital television (DTV) receiver comprising:
- a section-filtering unit for receiving a broadcast signal having a plurality of extended text tables (ETTs) that appear in transport stream packets having common PID values, each ETT including a section header containing a table identification (ID) extension field which serves to establish uniqueness of each ETT,
- wherein each ETT further includes an extended text message (ETM) which provides detailed descriptions of a virtual channel or an event associated with each ETT, and
- wherein the section filtering unit detects at least one pertinent ETT by section-filtering the plurality of ETTs using the table ID extension field included in the section header of each ETT.
A method of processing a broadcast signal in a digital television (DTV) receiver, the method comprising:
- receiving a broadcast signal comprising a plurality of program and system information (PSIP) tables that appear in transport stream packets having common PID values, wherein each PSIP table comprises a section header containing a table identification (ID) extension field which uniquely identifies each PSIP table;
- and
- detecting at least one PSIP table by section-filtering the plurality of PSIP tables using the table ID extension field included in the section header of each PSIP table.
A digital television (DTV) receiver comprising:
- a section-filtering unit for receiving a broadcast signal having a plurality of program and system information protocol (PSIP) tables that appear in transport stream packets having common PID values, each PSIP table including a section header containing a table identification (ID) extension field which uniquely identifies each PSIP table,
- wherein the section-filtering unit detects at least one pertinent PSIP table by section-filtering the plurality of PSIP tables using the table ID extension field included in the section header of each PSIP table.
