Abstract
This data reception apparatus includes a first buffer capable of retaining a received packet at least in units of error correction blocks and a first controller that requests a transmission apparatus to retransmit a lost packet in the error correction block retained in the first buffer and performs processing of recovering the lost packet, and reads, from the first buffer, the error correction block at a point of time at which each of a plurality of particular data correction-allowed times different from each other elapses, performs error correction on each error correction block read at each point of time, and outputs each error correction result.
Claims20
A data reception apparatus, comprising:
- processing circuitry configured to receive, from a data transmission apparatus through a network, two series of packets of data at two different transmission delays, wherein
- the two series of the packets include a first series of the packets and a second series of the packets,
- the first series of the packets is transmitted to an audio/video (AV) switcher for switching the first series of the packets to be transmitted back to the data transmission apparatus, and
- the second series of the packets is transmitted to an AV interface for playback.
A data transmission apparatus, comprising:
- processing circuitry configured to transmit, to a data reception apparatus through a network, two series of packets of data at two different transmission delays, wherein
- the two series of the packets include a first series of the packets and a second series of the packets,
- the first series of the packets is transmitted to an audio/video (AV) switcher for switching the first series of the packets to be transmitted back to, and received by, the data transmission apparatus, and
- the second series of the packets is transmitted to an AV interface for playback.

- transmitting, by a data transmission apparatus to a data reception apparatus through a network, two series of packets of data at two different transmission delays, wherein
- the two series of the packets include a first series of the packets and a second series of the packets,
- the first series of the packets is transmitted to an audio/video (AV) switcher for switching the first series of the packets to be transmitted back to, and received by, the data transmission apparatus, and
- the second series of the packets is transmitted to an AV interface for playback.
A system, comprising:
- a data transmission apparatus;
- and
- a data reception apparatus, wherein
- the data transmission apparatus is configured to transmit, to the a data reception apparatus through a network, two series of packets of data at two different transmission delays,
- the data reception apparatus is configured to receive the two series of the packets,
- the two series of the packets include a first series of the packets and a second series of the packets,
- the first series of the packets is transmitted to an audio/video (AV) switcher for switching the first series of the packets to be transmitted back to the data transmission apparatus, and
- the second series of the packets is transmitted to an AV interface for playback.
