Abstract
A receiving apparatus and method, and a transmitting apparatus, and method capable of improving a reproduction quality in a state where a packet loss occurs. The transmitting apparatus including a memory and an electronic processor communicatively connected to the memory. The electronic processor is configured to encode a data unit, generate a data packet by packetizing the data unit that is encoded, generate a time information packet by packetizing information indicating a decode and a display time relative to the data unit, and generate a stream by multiplexing the data packet, the time information packet, and identification information to identify the data unit.
Claims20
A transmitting apparatus comprising:
- a memory;
- and
- an electronic processor communicatively connected to the memory, the electronic processor configured to
- receive a data signal,
- encode a data unit supplied by the data signal,
- generate a data packet by packetizing the data unit that is encoded,
- receive a time signal,
- generate a time information packet by packetizing information indicating a decode and a display time relative to the data unit, the time information packet based on time information supplied by the time signal, and
- generate a stream by multiplexing the data packet, the time information packet, and identification information that identifies an association between the data unit and the time information packet,
- wherein the time information packet is separate from the data packet.
A transmitting method performed by a transmitting apparatus, the method comprising:
- receiving, with an electronic processor of the transmitting apparatus, a data signal;
- encoding, with the electronic processor, a data unit supplied by the data signal;
- generating, with the electronic processor, a data packet by packetizing the encoded data unit;
- receiving, with the electronic processor, a time signal;
- generating, with the electronic processor, a time information packet by packetizing time information indicating a decode and a display time relative to the data unit, the time information packet based on time information supplied by the time signal;
- and
- generating, with the electronic processor, a stream by multiplexing the data packet, the time information packet, and identification information that identifies an association between the data unit and the time information,
- wherein the time information packet is separate from the data packet.
A receiving apparatus comprising:
- a memory;
- and
- an electronic processor communicatively connected to the memory, the electronic processor is configured to
- demultiplex a data packet including a data unit that is encoded, a time information packet including time information that is indicative of a decode and a display time relative to the data unit, and identification information that identifies an association between the data unit and the time information from a stream,
- extract the data unit that is encoded from the data packet;
- restore the time information from the time information packet,
- associate the data unit that is encoded with the time information based on the identification information, and
- generate a second data unit by decoding the data unit that is encoded,
- wherein the time information packet is separate from the data packet.
A receiving method performed by a receiving apparatus, the method comprising:
- demultiplexing, with an electronic processor of the receiving apparatus, a data packet including a data unit that is encoded, a time information packet including time information that is indicative of a decode and a display time relative to the data unit, and identification information that identifies an association between the data unit and the time information from a stream;
- extracting, with the electronic processor, the data unit that is encoded from the data packet;
- restoring, with the electronic processor, the time information from the time information packet;
- associating, with the electronic processor, the data unit that is encoded with the time information based on the identification information;
- and
- generating, with the electronic processor, a second data unit by decoding the data unit that is encoded,
- wherein the time information packet is separate from the data packet.
