Abstract:
An error control method for video bitstream data used in wireless communication, comprising the steps of:(a) partitioning video bitstream data into units of information items having certain characteristics and encoding the video bitstream data; (b) calculating a checksum of each partitioned unit of the encoded video bitstream data for controlling errors in each partitioned unit of the encoded video bitstream data; (c) constituting a packet, in which each checksum calculated in the step (b) is added to the encoded video bitstream data and transmitting the packet through a wireless communication channel; and (d) receiving the packet transmitted in the step (c) and checking whether there is an error in each partitioned unit of the encoded video bitstream data through the checksum of each partitioned unit of the encoded video bitstream data.
