AI Technical Summary

Problems solved by technology

The video transcoding algorithm is mainly researched on video coding standards before HEVC such as H.264, MPEG-2, etc. Due to the different framework structure, the original video transcoding algorithm is not suitable for the current requirements and framework, so it needs to be proposed A New HEVC Video Transcoding Framework and Fast Transcoding Algorithm

Embodiment Construction

[0086] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0087] Such as figure 1 Shown, a kind of video multi-channel transcoding method based on HEVC comprises the following steps:

[0088] Step 1: Use video transcoding technology to decode the input video code stream to obtain the reconstructed video stream file and save its depth information and mode information;

[0089] Step 2: Encode the reconstructed video stream file through three encoders with different parameters to obtain three video streams, namely the first R1, the second R2 and the second R3;

[0090] Step 3: Use the classifier trained by the machine learning boosting algorithm to make preliminary predictions on the depth and mode information of each video stream, and use the preliminary prediction results, the information of the decoder and the encoding information of multiple video streams to sequentially analyze the video streams of each chan...

Abstract

The present invention discloses an HEVC (high efficiency video coding)-based video multi-channel transcoding method. According to the method, relationships between coding units and prediction units in the high-bit-rate original video streams of a decoding end and the low-bit-rate output video streams of a plurality of coding ends are analyzed; the relationships between the coding units and prediction units in the plurality of coding ends are considered; and therefore, the depth selection and mode selection of the coding units in a transcoding process are rapidly predicted by means of the discovered relationships, and therefore, coding speed can be increased.

Description

technical field [0001] The invention belongs to the field of video transcoding, and in particular relates to an HEVC-based video multi-channel transcoding method. Background technique [0002] In recent years, due to the rise of the live video industry, video transcoding algorithms have been a research hotspot in academia and industry. There are many different forms of video transcoding, such as the mutual conversion between different bit rates or different formats. Transcoding technology can allow different devices or different platforms to seamlessly connect, and can convert from high-quality video sources through wireless networks. To the receiving source of different requirements (mobile terminal, PC terminal, tablet computer terminal). In order to adapt to different network bandwidths, the transcoder can adaptively adjust different video bit rates. At present, many kinds of video compression standards have emerged corresponding to different multimedia applications, an...
