selection_category_name_text()
– A data structure containing a multiple string structure which specifies the genre category name; e.g., “Rugby.” Text strings are formatted according to the rules outlined in Section 6.10. The displayed string for the genre category name shall be limited to 24 characters or less. dcc_state_location_code – This 8-bit unsigned integer in the range 79 to 99 specifies the State or Territory to be added. The integer values specifying new States or Territories shall be those assigned by the ATSC. dcc_state_location_code_text() – The name of the new State or Territory in the format of a multiple string structure (see Section 6.10). state_code – An 8-bit unsigned number in the range 0 to 99 that identifies the State, Territory or Offshore (Marine Area) to which the county information to follow applies. state_code shall be coded according to State and Territory FIPS number codes according to ANSI INCITS 31- 2009 [7]. dcc_county_location_code – This 10-bit unsigned integer in the range 1 to 999 specifies a county within the state identified in state_code . Values for dcc_county_location_code shall be coded according to ANSI INCITS 31 [7]. dcc_county_location_code_text() – The name of a new county in the format of a multiple string structure (see Section 6.10). dccsct_descriptors_length – Total length of the descriptor list that follows (in bytes). dccsct_descriptors() – Zero or more descriptors, as appropriate, may be included. CRC_32 – This is a 32-bit field that contains the CRC value that ensures a zero output from the registers in the decoder defined in Annex A of ISO/IEC 13818-1 “MPEG-2 Systems” [13] after processing the entire DCC Selection Code Table section. 6.9 Core Descriptors Table 6.25 lists descriptor tags along with their names, and shows the use of each when the relevant table section listed is present in the transport stream. Table 6.25 indicates all the core descriptors, their tags, and their allowed locations in the PSIP tables. The service_location_descriptor() shall always be present in the terrestrial VCT (shown with an “S”). Table 6.25 does not specify the rules governing whether or not a particular descriptor must be present in any given situation. When used, some descriptors shall be in each indicated location (shown with an “M”). Some descriptors also may be present in a second location within either the terrestrial or the cable case (shown with an “O”). Asterisks mark the tables where the descriptors may appear without restrictions. 66 ATSC A/65:2013 Program and System Information Protocol 7 August 2013 Download 4.82 Kb. Do'stlaringiz bilan baham: |
