ABSTRACT:
In a video decoding method, the video data to be decoded is arranged in a first unit, which first unit includes a plurality of second data units, and each of which second data unit includes an information on a status of the second data unit. First, it is determined whether the status information in a current second unit is invalid or not. If it is determined that the status information in the second unit is invalid, the status information is changed into another one among a set of possible status information to decode the video data from the current second unit to a last second unit in a current first unit on the basis of the changed status information. Afterwards, if the decoding of video data from the current second unit to the last second unit in the current first unit was successful for none of the possible status information, a flag representing an encoding scheme of the video data is changed such that the flag indicates that the second unit is encoded in an inter-frame mode. Then, the video data from the current second unit to the last second unit in the current first unit is decoded according to the changed flag. Finally, the video data from the current second unit to the last second unit in the current first unit is replaced with those in a previous frame if the decoding of the video data in the step (d) was unsuccessful.
