Embodiment Construction

[0040] In the present invention, the encoding device obtains the original video frame sequence that needs to be encoded; uses the original video frame sequence to perform arithmetic operations between frames, compresses redundant information, obtains encoded information, and combines the encoded information and the arithmetic operation information between frames Of course, the arithmetic operation information is not necessarily sent to the decoding device, it is possible to pass the standard agreement in advance, that is to say, the encoding uses a fixed arithmetic operation rule, and the decoder knows this rule; The coding device obtains the coding information; and restores the original video frame sequence through the arithmetic operation information and coding information obtained from the coding device or pre-agreed with the coding device.

[0041] The present invention will be described in detail below in conjunction with specific embodiments.

[0042]In the embodiment of...

Abstract

The invention discloses one visual data compression method, which comprises the following steps: coding device gets original visual frame sequence; using all original visual frequency frame for computation to compress redundant information to get codes information and to send the information to the decoding device; decoding device gets coding information from coding device; through coding device getting the preset computation information and to restore original visual frequency sequence from coding device.

Description

technical field [0001] The invention relates to the technical field of video coding, in particular to a video data compression method. Background technique [0002] Digital TV, new generation mobile communication, broadband network communication and household consumer electronics technology are booming into high-tech industrial clusters, and their commonality is focused on multimedia information processing technology with video and audio as the main content, especially data compression technology. High-efficiency video coding technology is the key to realize high-quality, low-cost multimedia data storage and transmission. Now commonly used encodings include MPEG (Moving Picture Experts Group, Moving Picture Experts Group) 2 / MPEG4 / H.264, etc. The encoding technologies used mainly include predictive encoding, transform encoding, vector quantization encoding, etc. These video encoding standards and related technologies are in the Industry has been widely used. [0003] The vi...
