Abstract

The invention discloses an image data processing method, apparatus and system. The method comprises the following steps: a first processing device receives first image data transmitted by a first transmission channel and second image data transmitted by a second transmission channel, wherein the first image data are initial image data output by the first processing device or a second processing device, and the second image data are image data obtained by processing encoding and decoding processing on the initial image data; the first processing device obtains a first transmission time of the first image data in the first transmission channel, and a second transmission time of the second image data in the second transmission channel; and the first processing device obtains the transmission time of the second transmission channel according to the first transmission time and the second transmission time. By adoption of the image data processing method, apparatus and system, the technical problem that the transmission delay obtained by the image processing method in the prior art contains a system delay error is solved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a method, device and system for processing image data. Background technique [0002] In the real-time image codec transmission system, in order to comprehensively evaluate the performance of the system, it is necessary to test the system, for example, compare the image data received by the encoder with the image data output by the decoder to obtain the peak signal-to-noise ratio (Peak Signal to Noise Ratio, referred to as PSNR), structural similarity (Structural Similarity Index, referred to as SSIM), so as to test the compression quality index of the codec; count the number, length and time information of the network data packets during the transmission of the system, and compare the encoding The compression capability of the encoder is tested; the difference between the time when the initial image data enters the encoder and the time when the decoder outputs the image dat...
