Sony patents communication system that reports error correction failures
Sony has been granted a patent for a communication device that checks for data errors during transmission. If the system cannot fix a corrupted data packet, it creates a new report packet containing details about the failure and sends it back to the sender.
In the filing’s own words
To solve a problem related to error correction. A communication apparatus includes: a PHY that receives a first transmission signal conforming to a predetermined communication protocol from a communication partner apparatus and performs error correction on a plurality of first packets included in the first transmission signal; and a LINK that separates the plurality of first packets after error correction and generates a second packet including error correction impossible information of the first packet on which the error correction has not been correctly performed, and the PHY transmits a second transmission signal including the second packet to the communication partner apparatus.
What exactly they claim (claim 1)
1. A communication apparatus comprising: a physical layer (PHY) that receives a first transmission signal conforming to a predetermined communication protocol from a communication partner apparatus and performs error correction on a plurality of first packets included in the first transmission signal; a link layer (LINK) that separates the plurality of first packets after error correction and generates a second packet including error correction impossible information of at least one of the plurality of first packets on which the error correction has not been correctly performed, wherein the PHY transmits a second transmission signal including the second packet to the communication partner apparatus, the plurality of first packets includes at least one of an application packet or a first operation, administration, and maintenance (OAM) packet, the second packet includes a second OAM packet, the LINK includes an OAM unit that decodes the first OAM packet and generates the second OAM packet, the first OAM packet includes an error detection code, and the PHY detects an error in the first OAM packet on a basis of the error detection code and outputs an error detection signal; and a number-of-times storage unit that stores a number of times of detection of an error of the first OAM packet by the OAM unit for each transmission unit of the first transmission signal, wherein the second OAM packet includes information of the number of times stored in the number-of-times storage unit.
