1. the equipment for decoding to video, described equipment comprises:

  • Receiver, is configured to receive the bit stream of the information of the final coefficient positions comprised about transform block;

    Arithmetic decoder, be configured to by performing based on contextual arithmetic decoding described bit stream, obtain the prefix bits string of the final coefficient positions among the information about final coefficient positions, and when described prefix bits string is greater than predetermined value, obtain suffix bits string according to bypass mode from described bit stream;

    Inverse binaryzation device, be configured to perform to described prefix bits string the prefix that inverse binaryzation obtains inverse binaryzation according to blocking binaryzation scheme, and according to regular length binaryzation scheme, the suffix that inverse binaryzation obtains inverse binaryzation performed to described suffix bits string;

    Symbol reconstructor, is configured to the symbol by using the suffix of the prefix of inverse binaryzation and inverse binaryzation to rebuild the final coefficient positions of instruction transform block,Wherein, be by using the size of context index and the transform block determined based on binary digit index to perform based on contextual arithmetic decoding.
