Problems solved by technology

[0012] Although encoding in this way can compress encoded video data with high image quality and high compression rate, it does not take into account the decoding capability of the decoder
When the computing power of the decoder is insufficient, it will make it impossible for the decoder to decode the video data smoothly.

Embodiment Construction

[0041] The first embodiment of the present invention is an encoder that further adjusts the amount of decoding calculation according to known encoding parameters, which are generated from video data, that is, figure 1Encoding parameters 120 are shown. This embodiment can process sub-pixels, so applicable compression standards include H.264 compression standard, MPEG2 compression standard, and MPEG4 compression standard. figure 2 is the dynamic estimation and mode decision unit of the encoder (corresponding to figure 1 A schematic diagram of the dynamic estimation and mode decision unit 121). As shown in the figure, the dynamic estimation and mode determination unit includes an estimation unit 201 , a parameter generation unit 203 , an addition unit 205 and a complexity calculation unit 207 . The estimation unit 201 is used to receive the video data 200 and calculate the first encoding parameter 202 according to the video data 200, wherein the video data 200 is figure 1 The...

Abstract

The invention relates to a coder for adjusting the code calculation, relative method and computer readable medium, wherein the coder comprises parameter generator, summing unit, and complexity calculator, while it can adjust the code calculation via the first code parameter; the first code parameter is generated by video data; the method and computer readable medium comprise that: the parameter generator generates image quality parameters; the summing unit sums the first code parameter and image quality image to generate the second code parameter; the complexity calculator via the second coding parameter calculates out the complexity, to generate the third code parameter and refresh parameter; the parameter generator via refresh parameter refreshes the image quality parameter; the coder uses the third code parameter to code video.

Description

technical field [0001] The present invention relates to an encoder and a method for adjusting the amount of decoding calculation, more specifically, an encoder and a method for adjusting the amount of decoding calculation according to the complexity of decoding. Background technique [0002] In recent years, the transmission capacity of digital communication media including cable TV, satellite, Internet, etc. has increased rapidly. Although increasing in capacity, these transmission capacities are still too small for the transmission of uncompressed high-quality video data. In today's increasingly strong demand for multi-channel, mobile video, high-quality video, and high-resolution video, the growth rate of digital communication media capacity is far from meeting the needs of these high-quality video data. [0003] In addition to continuous breakthroughs in transmission capacity, research and development of more efficient video compression solutions is another solution. T...
