Problems solved by technology

[0003] The existing 8KVR video can only be encoded in H265, and the transmission of the rtmp standard protocol cannot be realized during transmission, and the video live broadcast system under the existing technology cannot perform 8K video decoding and encoding in real time during the process of transcoding and downsampling, usually First temporarily decode the video, and then re-encode it into the required format and data encoding speed. The video occupies a large space, which increases the difficulty of transcoding and downsampling

Abstract

The invention discloses an 8K down-sampling encoder and a using method thereof. Specifically, the invention relates to the field of transcoding, the 8K down-sampling encoder is used for realizing down-sampling conversion from a unified media stream format of an input end to a plurality of output ends with different media stream formats, and comprises a public transcoding module, the input end of the public transcoding module is electrically connected with a regulation and control module, and the output end of the regulation and control module is electrically connected with a public transcodingmodule, a down-sampling transcoding module and a data buffer. According to the invention, a 4K or 2Krtmp video is down-sampled for 8Krtmp stream transcoding and is played in a terminal; the 8KVR livebroadcast multi-terminal playing requirement is met, transcoding downsampling is carried out on the common part of short transcoding downsampling requirements from an input end to multiple outputs, and the effect of smooth watching of multiple mobile terminals is achieved.

Description

technical field [0001] The present invention relates to the technical field of transcoding, and more specifically, the present invention relates to an 8K down-sampling encoder and a method for using the same. Background technique [0002] Downsampling refers to converting the compressed and coded video code stream into another resolution video code stream to adapt to different network bandwidths, different terminal processing capabilities and different user needs. Transcoding and downsampling is essentially a process of first decoding and then encoding, so the code stream before and after conversion may or may not follow the same video coding standard. [0003] The existing 8KVR video can only be encoded in H265, and the transmission of the rtmp standard protocol cannot be realized during transmission, and the video live broadcast system under the existing technology cannot perform 8K video decoding and encoding in real time during the process of transcoding and downsampling...
