Method and device for reconstructing video time sequence

Abstract

The invention provides a method and device for reconstructing a video time sequence. The method for reconstructing the video time sequence comprises the steps that video data is acquired; the video data is written into a memory, wherein a first in first out memory is adopted as the memory; and the video data written into the memory is read from the memory according to a set standard time sequence while the video data is written into the memory, and a standard video time sequence corresponding to the video data is obtained. By adopting the technical scheme, the non-standard video time sequence can be converted into the standard video time sequence meeting the standard time sequence requirements, the utilization rate of the non-standard video time sequence is increased, and video source waste is avoided.

Description

technical field [0001] The present invention relates to the technical field of video transmission, in particular to a method and device for reconstructing video sequence. Background technique [0002] According to the regulations of the Consumer Electronics Association (CEA) and the Video Electronics Standards Association (VESA), video data should be transmitted in the form of standard video timing, so that the video data can be displayed correctly at the receiving end. data. [0003] In the process of video data transmission, it often happens that the timing of vertical synchronous field signals and effective data line signals of video data is not standard, resulting in the transmitted video data not meeting the video timing standards stipulated by CEA or VESA. When the video data receiving end receives non-standard video timing, it cannot display correctly, so it considers the received non-standard video timing as useless information, and discards the received video data....

Problems solved by technology

[0003] In the process of video data transmission, it often happens that the timing of the vertical synchronous field signal and the effective data line signal of the video data is not standard, resulting in the transmitted video data not conforming to the video timing standard stipulated by CEA or VESA

When the video data receiving end receives non-standard video timing, it cannot display correctly, so it considers the received non-standard video timing to be useless information, so it discards the received video data

In the above processing process, the use of non-standard video timing is directly abandoned, resulting in a huge waste of video resources
