摘要

The video decoder is configured to decode a plurality of video frames subdivided into one or more slice sets.DecoderTo select the mode of operation for the decoding of slicesNo prediction of video content of the current frame based on the video content of the previous frameUsing the independent encoding modeOr there is a pixel block prediction based on one block of pixels in the previous frameUsing single prediction modeOr there is a pixel block prediction based on pixels of two or more blocks of one or more previous framesUsing bidirectional prediction modeIndicates whether the slice has been encoded.Slice type information is evaluated.The video decoder includes an arithmetic decoder for providing a decoding binary sequence based on the encoding representation of the binary sequence.The arithmetic decoder is configured to determine the first source statistics using the first estimate parameter and to determine the second source statistics using the second estimated parameter.Arithmetic DecoderBased on the first source statistics (at)Based on the second source statisticsIt is configured to determine the combined source statistics.Arithmetic DecoderBased on the binding source statisticsUsed to map encoded representations of binary sequences to decrypted binary sequencesThe distance subdivision is configured to determine one or more range values.
