摘要： Provided are a method and apparatus for determining a block mode using bit-generation probability estimation in motion picture coding. In H.264 video coding for Internet protocol (IP)-television (TV), the method and apparatus first determine whether or not a current block mode is a skip mode or a direct-prediction mode using bit-generation probability estimation, thereby reducing the amount of computation. By minimizing the amount of computation for determining a block mode, it is possible to increase an encoding rate and also minimize deterioration in image quality.

摘要： The present invention relates to a method for a video encoder to determine an inter mode. The video encoder selects first search modes by using optimized inter mode information of a correlation macroblock having the same position as a current macroblock in a previous frame, in order to determine the inter mode. The video encoder compares a rate-distortion cost of the correlation macroblock and a rate-distortion cost of the mode that is selected as the minimum cost mode from among the first search modes, and determines whether to terminate an inter mode determination process early. When the early termination condition is satisfied, the video encoder determines the search mode having the minimum rate-distortion cost from among the first search modes as the optimized inter mode of the current macroblock, and terminates the inter mode determination process early. When the early termination condition is not satisfied, the video encoder selects second search modes to additionally perform an inter prediction process, and determines the corresponding search mode having the minimum rate-distortion cost as the optimized inter mode of the current macroblock.

摘要： The present invention relates to a method for a video encoder to determine an inter mode. The video encoder selects initial candidate modes by using inter mode information of a previous frame so as to determine the inter mode, estimates a macroblock having the greatest correlation with a current macroblock in the previous frame, compares the rate-distortion cost of the corresponding macroblock and the rate-distortion cost of the selected mode from among the initial candidate modes, and determines whether to terminate the inter mode determination process early. When the early termination condition is satisfied, the video encoder determines the candidate mode having the minimum rate-distortion cost from among the initial candidate modes as the inter mode of the current macroblock, and terminates the inter mode determination process early. When the early termination condition is not satisfied, the video encoder additionally performs an inter prediction process by selecting additional candidate modes, and determines the candidate mode having the determined minimum rate-distortion cost as the inter mode of the current macroblock.
