Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the present invention clearer, the various embodiments to be described below will refer to the corresponding drawings, and these drawings constitute a part of the embodiments, which describe various possible implementations of the present invention. kind of embodiment. It is to be understood that other embodiments may be utilized or structural and functional modifications may be made to the embodiments set forth herein without departing from the scope and spirit of the present invention.

[0026] In an embodiment of a video deinterleaving method provided by the present invention, as figure 1 shown, including the following steps:

[0027] S1. Receive video images P0, P1, P2, P3, P4, ... P(m+1); that is, a received video file can be divided into m+1 half-frame pictures, where P0 (even), P1 ( Odd), P2 (even), P3 (odd), P4 (even), ... P(m+1) are arranged in order of even and odd.

[0028] S2. Set virtual...

Abstract

Provided is a video de-interleave method comprising steps of: S1, receiving video images P0, P1, .., and P(m+1); S2, setting virtual images P0', P1', .., and Pm'; S3, calculating pixel moving direction from Pn to P(n+1); S4, obtaining the moving vector point Tn = Pn*k+P(n+1)*(1-k) of the Pn' with component synthesis of the Pn and the P(n+1), and obtaining an image Pn' with a formula Pn'= PnP(n+1)+Tn; S5, delivering the image Pn' to a display buffer area to be displayed; and S6, determining whether n is equal to m+1, n = n+1 and returning to S3 if not and ending the method if yes. The video de-interleave method resolves a problem of converting interlaced video signals into progressive video signals to be outputted, enables video display to be close to a real effect, decreases resource occupied by a CPU, and enables the CPU to process other tasks while processing images.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a video deinterleaving method. Background technique [0002] In order to resist interference in communication systems, channel coding techniques are often introduced, such as Hamming coding, cyclic codes, convolutional codes, etc. However, the error correction capability of channel coding such as Hamming coding is very limited, especially when there are continuous burst errors, its error correction capability is very limited. Therefore, in order to increase the anti-interference ability of the system and give full play to the advantages of channel coding, interleaving technology is introduced. The core idea of ​​interleaving is to disrupt the order of the original information symbols. If there is a relatively strong burst interference at a certain moment , when continuous bit errors are caused, due to the introduction of interleaving technology, the bit errors can ...
