Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Time-controlled method the first embodiment flow process of Digital Television of the present invention as shown in Figure 1, it can comprise:
Step 101: the TDT Time and Date Table in the analyzing atransmission stream and TOT Time Offset Table.The set-top box searching programs, the service information list in the analyzing atransmission stream is obtained TDT Time and Date Table and TOT Time Offset Table in the code stream, and it is resolved.
TDT Time and Date Table provides current date, time, and the time and date list structure is as follows:
The semanteme of time and date section is:
Table identifier table_id:0x70.
Duan Yufa designator section_syntax_indicator:1 bit field is answered reset.
Segment length section_length:12 bit field, front two are put " 00 ".The byte length of this section that its expression begins from the next byte of this field.
UTC(Coordinated Universal Time, Coordinated Universal Time(UTC)) time UTC_time:40 bit field comprises with UTC and MJD(Modified Julian Day, Modified Julian Date) the form current time and the date that represent.The front 16 bit representation MJD date codes of this field, all the other 24 by 4 BCD(Binary-Coded Decimal, binary-decimal code) coding, represent 6 numerals.
Example: 93/10/1312:45:00 is encoded as " 0xc079124500 ".
Reserve reserved: when term " reserved " uses in the clause of definition coded bit stream, represent that this value is in ISO(International Organization for Standardization in future, International Standards Organization) might be used to during the standard expanded definition.
Reserve and use reserved_future_use: when term " reserved_futre_use " uses in the clause of definition coded bit stream, represent that this value is in ETSI(European Telecommunications Standards Institute in future, ETSI) might be used to during the standard expanded definition.
TOT Time Offset Table provides and current time, date and local zone time skew relevant information.The TOT Time Offset Table list structure is as follows:
Table identifier table_id:0x73.
Duan Yufa designator section_syntax_indicator:1 bit field is answered reset.
Segment length section_length:12 bit field, front two are put " 00 ".The byte length of this section that its expression begins from the next byte of this field.
UTC time UTC_time:40 bit field comprises the current time and the date that represent with UTC and MJD form.The front 16 bit representation MJD date codes of this field are pressed 4 BCD codings, are represented 6 numerals for all the other 24.
Example: 93/10/1312:45:00 is encoded as " 0xc079124500 ".
Descriptor length of the cycle descriptors_loop_length:12 bit field is pointed out the total byte length of the descriptor that begins from the next byte of this field.
The CRC_32:32 bit field.Comprised CRC(Cyclic Redundancy Check, cyclic redundancy check (CRC) code) value, crc value is a kind of check value.
Reserve reserved: when term " reserved " uses, represent that this value might be used to during the iso standard expanded definition in future in the clause of definition coded bit stream.
Reserve to use reserved_future_use: when term " reserved_futre_use " uses, represent that this value might be used to during the etsi standard expanded definition in future in the clause of definition coded bit stream.
