Patent

CA 2554143

The present invention relates to a digital signal coding/decoding apparatus for video compression coding and compressed video data transmission. The invention provides a digital signal coding apparatus for partitioning a digital signal into predetermined units for compression coding, comprising: an arithmetic coding unit for compressing, by arithmetic coding, the digital signal partitioned into the units, wherein said arithmetic coding unit multiplexes information representing an arithmetic coding status, occurring when a given transmission unit has been coded, into data constituting a subsequent transmission unit. Utilizing the present invention a high degree of error resiliency is ensured.
