Embodiment Construction

[0022] The following examples will be used in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0023] A fast encoding method in the video encoding of the present invention specifically optimizes the predictive encoding steps of the encoder, and its basic principle is to decide whether to quickly skip the intra-frame prediction module based on the encoding information after the inter-frame prediction, thereby reducing the computational complexity Encode with the accelerated encoder, such as Figure 5 As shown, it specifically includes the following steps,

[0024] Step (1), information acquisition. It is responsible for obtaining some basic coding information of the coded block where the inter-frame prediction is located. Among them, the basic coding information includes but not limited to:

[0025] 1) Q...

Abstract

The invention discloses a fast coding method in video coding. The method comprises the following steps: after performing inter-frame prediction on each frame of video content by an encoder, obtainingvarious encoding information according to inter-frame prediction; judging whether intra-frame prediction needs to be skipped or not in a self-adaptive mode, if it is determined that intra-frame prediction needs to be skipped, directly performing the next encoding step. The prediction template is simplified, the encoding steps are reduced, and therefore on the premise that encoding performance losses are hardly caused, the computation complexity of the encoder is reduced, and the encoder is accelerated.

Description

technical field [0001] The invention relates to a fast coding method for video coding frames, in particular to an accelerated optimization algorithm for prediction technology in a video coder, and belongs to the technical field of video coding. Background technique [0002] With the continuous development of multimedia digital video applications and the continuous improvement of people's demand for video cloud computing, the data volume of the original video source makes the existing transmission network bandwidth and storage resources unbearable. Therefore, the compression of video signal has become one of the hot spots of academic research and industrial application at home and abroad. Video compression, also known as video coding, aims to eliminate redundant information between video signals. So far, domestic and foreign standardization organizations have successively formulated a variety of different video coding standards. The mainstream video coding standards all adop...
