Info

36 duration: A 24-bit field containing the duration of the event in hours, minutes, seconds. format: 6 digits, 4-bit BCD = 24 bit. EXAMPLE 3: 01:45:30 is coded as "0x014530". running_status: This is a 3-bit field indicating the status of the event as defined in table 6. For an NVOD reference event the value of the running_status shall be set to "0". free_CA_mode: This 1-bit field, when set to "0" indicates that all the component streams of the event are not scrambled. When set to "1" it indicates that access to one or more streams is controlled by a CA system. descriptors_loop_length: This 12-bit field gives the total length in bytes of the following descriptors. CRC_32: This is a 32-bit field that contains the CRC value that gives a zero output of the registers in the decoder defined in annex B after processing the entire private section. 5.2.5 Time and Date Table (TDT) The TDT (see table 8) carries only the UTC-time and date information. The TDT shall consist of a single section using the syntax of table 8. This TDT section shall be transmitted in TS packets with a PID value of 0x0014, and the table_id shall take the value 0x70.

It specifies the number of bytes of the section, starting immediately following the section_length field and up to the end of the section. UTC_time: This 40-bit field contains the current time and date in UTC and MJD (see annex C). This field is coded as 16 bits giving the 16 LSBs of MJD followed by 24 bits coded as 6 digits in 4-bit BCD. EXAMPLE: 93/10/13 12:45:00 is coded as "0xC079124500". DVB BlueBook A38
37 5.2.6 Time Offset Table (TOT) The TOT (see table 9) carries the UTC-time and date information and local time offset. The TOT shall consist of a single section using the syntax of table 9. This TOT section shall be transmitted in TS packets with a PID value of 0x0014, and the table_id shall take the value 0x73.
