Receiving method, receiving device, and transmission and reception system

A receiving method used by a receiving device which receives a first data unit in which data making up an encoded stream is stored, the first data unit storing a plurality of second data units, the receiving method comprising:

• receiving (i) the first data unit, (ii) first time information indicating a presentation time of the first data unit, and (iii) identification information indicating that at least one correction-requiring second data unit is possibly included in the first data unit;
• and
• determining whether or not the at least one correction-requiring second data unit is included in the first data unit indicated by the received identification information, wherein
• the at least one correction-requiring second data unit is a second data unit that requires correction,
• the at least one correction-requiring second data unit is presented at a presentation time that requires correction or decoded at a decoding time that requires correction, and
• the at least one correction-requiring second data unit is positioned in a presentation order of presenting the plurality of second data units so as to be positioned after a head second data unit positioned at a head in the presentation order of presenting the plurality of second data units.

A transmitting device which transmits a first data unit in which data making up an encoded stream is stored, the first data unit storing a plurality of second data units, the transmitting device comprising:

• a processor;
• and
• a non-transitory memory having stored thereon executable instructions, which when executed, cause the processor to perform:
• generating first time information indicating a presentation time of the first data unit, based on reference time information received from an external source;
• and
• transmitting (i) the first data unit, (ii) the generated first time information, and (iii) identification information indicating that at least one correction-requiring second data unit is possibly included in the first data unit,
• wherein
• the at least one correction-requiring second data unit is a second data unit that requires correction,
• the at least one correction-requiring second data unit is presented at a presentation time that requires correction or which is decoded at a decoding time that requires correction, and
• the at least one correction-requiring second data unit is positioned in a presentation order of presenting the plurality of second data units so as to be positioned after a head second data unit positioned at a head in the presentation order of presenting the plurality of second data units.

A receiving device which receives a first data unit in which data making up an encoded stream is stored, the first data unit storing a plurality of second data units, the receiving device comprising:

• and
• a non-transitory memory having stored thereon executable instructions, which when executed, cause the processor to perform:
• receiving (i) the first data unit, (ii) first time information indicating a presentation time of the first data unit, and (iii) identification information indicating that at least one correction-requiring second data unit is possibly included in the first data unit;
• and
• determining whether or not the at least one correction-requiring second data unit is included in the first data unit indicated by the received identification information, wherein
• the at least one correction-requiring second data unit is a second data unit that requires correction,
• the at least one correction-requiring second data unit is presented at a presentation time that requires correction or which is decoded at a decoding time that requires correction, and
• the at least one correction-requiring second date unit is positioned in a presentation order of presenting the plurality of second data units so as to be positioned after a head second data unit positioned at a head in the presentation order of presenting the plurality of second data units.
