TH131500B - Internal prediction mode selection for visual coding By using CA, ABC - Google Patents

Abstract

For blocks of video signal information The video encoder can give the signal Video signal decoder By using an adaptive binary coding process with The context is fundamental (CA, ABC), an internal prediction mode that is chosen by the code word which has been Transmission to a modified internal prediction mode index This video decoder can Carry out context-based adaptive binary coding processes (CABAC) to calculate the code word, which is signaled by the image signal encoder, defines an indexed internal prediction mode that is modified according to the code word. Set the mode that Nya will go on. As possible, based on context Sends the modified pre-mode index to the index. Of the internal prediction mode by comparing the index of the modified internal prediction mode With the mode index of the most probable mode And define the internal prediction mode that has been Select, which will be used to encode blocks of video signals with an index of the internal prediction mode as the basis
