Abstract:
1. A video image coding apparatus, comprising: image dividing means for dividing an input video image signal into a plurality of image divisions; a plurality of coding sections for individually compression encoding the plurality of image divisions outputted from said image dividing means; multiplexing means for multiplexing the plurality of compression encoded data from said coding sections to reconstruct compression encoded data and outputting the compression encoded data as a compression stream; and coordinated coding control means for receiving some or all of coding parameters, image status parameters and coding result parameters which are extracted from said plurality of coding sections, adjusting the parameters to be used for compression encoding by said coding sections in a control period or under a control condition determined in advance, and supplying the parameters to said plurality of coding sections in order to achieve coordinated coding between the coding sections; wherein said coordinated coding control means determines basic coding control parameters based on parameters such as a bit rate and an image size, and supplies the determined basic coding control parameters to said image dividing means, said plurality of coding sections and said multiplexing means; and wherein said coordinated coding control means evaluates coding situations of said plurality of image divisions with parameters supplied thereto over a communication bus, calculates coding control parameters and supplies the calculated coding control parameters over said communication bus.
