Abstract:
1. A communication control apparatus for performing communication by transmitting/receiving a plurality of packets included in a plurality of image frames through a network, the communication control apparatus comprising: a transmitter; a processor; and a memory device storing instructions which when executed by the processor, cause the processor to operate with the transmitter to: (a) for at least one of the plurality of packets included in a subsequent image frame, determine if encoding parameters of the subsequent image frame are different from encoding parameters of a previous image frame, the previous image frame including at least one packet which was previously transmitted; (b) if the determination is that the encoding parameters of the subsequent image frame are different from the encoding parameters of the previous image frame, add a main header to the at least one packet included in the subsequent image frame, the main header including the encoding parameters of the subsequent image frame; (c) if the determination is that the encoding parameters of the subsequent image frame are not different from the encoding parameters of the previous image frame, do not add the main header to the at least one packet included in the subsequent image frame; and (d) transmit the at least one packet included in the subsequent image frame, wherein if the main header is not added to the at least one packet included in the subsequent image frame, the at least one packet included in the subsequent image frame is transmitted without the encoding parameters of the subsequent image frame.
