Abstract
Provided is an image data communication method. The method comprises generating encoding data by encoding image data, generating recovery data by using the encoding data, generating packets by packetizing the encoding data and the recovery data, and transmitting the generated packets. The generating of the recovery data comprises dividing the encoding data into a plurality of fragmented data, and generating the recovery data by performing an XOR operation on at least two fragmented data among the plurality of fragmented data.
Claims20
An image data communication method comprising:
- generating encoding data by encoding image data;
- generating recovery data by using the encoding data;
- generating packets by packetizing the encoding data and the recovery data;
- and
- transmitting the generated packets;
- wherein the generating of the recovery data comprises:
- dividing the encoding data into a plurality of fragmented data;
- and
- generating the recovery data by performing an XOR operation on at least two fragmented data among the plurality of fragmented data.
An image data communication method comprising:
- receiving a plurality of packets and at least one recovery packet;
- determining whether a missing packet exists among the plurality of packets;
- performing a missing packet recovery by using the plurality of packets and the at least one recovery packet when the missing packet exists, so as to recover the image data;
- and
- performing decoding on the plurality of packets when the missing packet does not exist, so as to recover the image data,
- wherein the missing packet recovery is performed by using an XOR operation on at least one packet among the plurality of packets and the recovery packet.
An image data communication device comprising:
- a first encoding unit configured to encode an image signal to output the encoded signal as a first down signal;
- a second encoding unit configured to receive the first down signal, perform missing packet recovery encoding on the first down signal to output the encoded signal as a second down signal;
- a packetizing unit configured to receive the second down signal, packetize the second down signal to output the packetized signal as a third down signal;
- and
- a transceiver configured to receive the third down signal to transmit the received signal to an external device,
- wherein the missing packet recovery encoding further comprises dividing the first down signal into a plurality of first fragmented data, performing an XOR operation on at least two fragmented data among the plurality of first fragmented data to generate first recovery data, and outputting the plurality of first fragmented data and the first recovery data as the second down signal.
