ABSTRACT:
A method and an encoder (1001) are disclosed for encoding an input bitstream derived from a block of coefficients relating to video data. Leading zeros and tailing zeros are determined and removed (4050, 4070) from the input bitstream. Parity bits are generated (60) for bits remaining in the input bitstream. An encoded bitstream (1032) is then generated, where the encoded bitstream (1032) comprises the number of leading zeros, the number of tailing zeros, and the parity bits.
