Abstract
An electronic device includes a NACK buffer configured to temporarily store first packets and second packets, and processing circuitry configured to generate a plurality of frames, which include reference frames depending on decoding of another frame and non-reference frames independent of decoding of another frame, based on hierarchical predictive (P) coding, generate the first packets forming the reference frames and the second packets forming the non-reference frames, based on the plurality of frames, transmit the first packets and the second packets to an external device, receive a NACK request indicating retransmission target packets that have failed to be received by the external device, determine to not retransmit at least some of the retransmission target packets corresponding to the NACK request.
