Embodiment Construction

[0044] The method for establishing the event keyword table of the present invention and the method for program search using the table will be described below with specific embodiments.

[0045] In order to better understand the present invention, the structure of the EKT is first described here, and the structure of the EKT is described here according to the provisions of the PSIP protocol in the ATSC standard. The EKT, like other tables in the PSIP, is also conceptual It is divided into several segments and packaged according to the Mpeg-2 standard for transmission to the user terminal by the TS stream. The following table 1 is the grammatical structure of the segment in the event keyword table:

[0046] Syntax Bits Format

[0047] event_keyword_table_section(){

[0048] table_id 8 0xDB

[0049] section_syntax_indicator 1 '1'

[0050] private_indicator 1 '1'

[0051] reserved 2 '11'

[0052] section_length 12 uimsbf

[0053] source_id 16 uimsbf

[0054] reserved 2 "11"...
