This paper proposes a new variable-to-fixed length arithmetic coding (VFAC) with error detecting capability. It achieves VF coding by inserting the internal state of the decompressor into compressed data. The internal state represents the offset of the sub-interval corresponding to the decompressed symbol and is also used for error detection. Convolutional operations are applied to encoding and decoding for improving error control capability. Proposed VFAC is evaluated by theoretical analysis and computer simulations. Simulation results show that more than 99.3% of errors occurring in a codeword can be detected
