Abstract
A method and computer program product for performing error control of video bitstream data encoded according to a data partition technique used in communication through a wireless channel. The method includes 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 for controlling errors in each partitioned unit of the encoded video bitstream data, (c) constituting a packet, in which each checksum calculated in a 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. According to the above method, it is possible to effectively detect the errors of the respective partitioned video bitstream data items and to use partial data without abandoning the entire video bitstream packet when errors occur in a specific portion of the video bitstream data by calculating the CRCs of the respective partition regions of the video bitstream data encoded according to a data partition technique.
