Video compression using context-based adaptive arithmetic coding

A new entropy coding scheme for video compression is presented. Context models are utilized for efJicient prediction of the coding symbols. A novel binary adaptive arithmetic coding technique is employed to match the conditional entropy of the coding symbols given the context model estimates. The adaptation is also employed to keep track of non-stationary symbol statistics. Our new approach has...

Multialphabet Arithmetic Coding at 16 MBytes/sec

We present the design and performance of a non-adaptive hardware system for data compression by arithmetic coding. The alphabet of the data source is the full 256-symbol ASCII character set, plus a non-ASCII end-ofle symbol. The key ideas of our system are the non-arithmetic representation of the current interval width, which yields improved coding e ciency in the interval-width update, and a r...

Random Chaotic Arithmetic Coding for Video Compression and Encryption

Submitted: Sep 7, 2013; Accepted: Nov 6, 2013; Published: Nov 10, 2013 Abstract: This paper studies the joint video compression and encryption, which gains good attention in past couple of years due to its reduced computational complexity. In this paper, we present a multimedia data encryption scheme based on arithmetic coding, which we refer to as Random Chaotic Arithmetic Coding (RCAC). In RC...

Error Correcting Arithmetic Coding for Robust Video Compression

In this paper we present a novel error correcting arithmetic co/decoder, based on forbidden symbol detection and maximum a posteriori estimation. The error correction goal is obtained by means of a sub-optimal metric-first search technique that exhibits attractive performance in terms of error recovery and decoding complexity. The proposed technique is able to compress the input data and at the...

Arithmetic Coding for Data Compression

Arithmetic coding provides an e ective mechanism for removing redundancy in the encoding of data. We show how arithmetic coding works and describe an e cient implementation that uses table lookup as a fast alternative to arithmetic operations. The reduced-precision arithmetic has a provably negligible e ect on the amount of compression achieved. We can speed up the implementation further by use...
