摘要： A decoding device is suitable for a context-based adaptive binary arithmetic coding (CABAC) technique and allows a real-time decoding of high-definition video. The CABAC decoding device allows a simultaneous performing since determination according to multiple conditions is based on logic circuits when the device is formed in hardware. Additionally, when one macro block starts to be decoded, the device reads and stores information about neighboring macro blocks at a time from a memory. Therefore, the device does not need to access the memory at every operation and this improves the overall decoding speed.

摘要： Provided are a method and device for storing video on the basis of a variable bit allocation to variably control a buffer size. Also provided are video encoding and decoding apparatuses using the same. The device divides a video image to be stored into a plurality of first basic blocks, checks pixel values of second basic blocks for each of the divided first basic blocks, and allocates bits to each of the first basic blocks according to a difference between maximum and minimum values of the checked pixel values. Also, the device compresses and stores pixel information about the first basic block in the allocated bits, and then de-compresses the compressed pixel information according to the maximum and minimum values for each of the first basic blocks.
