Abstract
The reception method including: a step of recovering (18) a transport packet TS, the transport packet TS conveying a SI/PSI table, and the SI/PSI table including a version field; and a step of reading (20) the value of the version field of the SI/PSI table conveyed by the transport packet TS, is characterized in that it includes: a step of comparison (22) of the read value of the version field of the SI/PSI table with a recorded value; and in the case where the read value is different from the recorded value: a step of recovery (30) of the whole of the SI/PSI table; and a step of recording (32) the read value in place of the recorded value.
Claims6
A method of reception, by a DVB-H handheld digital television receiver (4), of a DVB digital television transport stream comprising transport packets TS, said reception method comprising:
- a step of recovering (18) a transport packet TS, the transport packet TS conveying a SI/PSI table, and the SI/PSI table comprising a version field;
- and
- a step of reading (20) the value of the version field of the SI/PSI table conveyed by the transport packet TS,
- characterized in that it comprises:
- a step of comparison (22) of the read value of the version field of said SI/PSI table with a recorded value;
- and
- in the case where the read value is different from the recorded value:
- a step of recovery (30) of the whole of the SI/PSI table,
- a step of recording (32) the read value in place of the recorded value;
- and
- a step of recovering, in a predetermined period of time, following succeeding SI/PSI service information tables.
A device for receiving a DVB digital television transport stream comprising transport packets TS, said reception device comprising:
- means for recovering (8) a transport packet TS, the transport packet TS conveying a SI/PSI table, and the SI/PSI table comprising a version field;
- and
- reading means for reading (10) the value of the version field of the SI/PSI table conveyed by the transport packet TS;
- characterized in that it comprises:
- means for comparison (14) of the read value of the version field of said SI/PSI table with a recorded value;
- means for recovery (16), in the case where the read value is different from the recorded value, of the whole of the SI/PSI table;
- means for recording (12), in the case where the read value is different from the recorded value, the read value in place of the recorded value;
- and
- means for recovering, in a predetermined period of time, in the case where the read value is different from the recorded value, following succeeding SI/PSI service information tables.
