Embodiment Construction

[0045] In order to facilitate the understanding and description of the embodiments provided in the present application, first introduce several concepts related to the embodiments of the present application.

[0046] I frame: Also called intra picture, it represents a key frame. It retains the complete data information of a picture and can be decoded according to the frame data.

[0047] GoP: short for Group of Pictures. In video coding, the image sequence between I frame and I frame

[0048] Pixel: The basic unit of video display. Each pixel can have its own color value and can be represented by three primary colors.

[0049] Resolution: The ability of the display system to distinguish details. The higher the resolution, the more picture pixels.

[0050] Frame rate: The number of frames displayed per second in the video.

[0051] Color gamut: the sum of the colors that the technical system can produce, indicating the limit of the color range that can be displayed

[0052] Color space: a...

Abstract

Embodiments of the invention provide a video transmission method. The method comprises the following steps that a server converts an original frame of a first video into an expression frame of the first video and converts an original frame of a second video into an expression frame of the second video, wherein the expression frame of the first video and the expression frame of the second video have the same resolution and the same bit depth; the server determines an average pixel value of pixel points of the expression frame of the first video and the expression frame of the second video whichhave the same timestamp, and determines a third video according to the average pixel value; the server encodes the third video; and the server sends the encoded third video to a client. A problem ofhigh bandwidth demand under a condition of high concurrency is solved.

Description

Technical field [0001] This application relates to the field of communications, and in particular to a video transmission method and device. Background technique [0002] 4K HD video refers to a video with a resolution of 4096×2160. Compared with traditional HD and SD video, 4K HD video has more pixels, higher frame rate, higher dynamic range and wider color gamut. In terms of color model representation, 4K high-definition video requires a higher bit depth, so it occupies more space than high-definition and standard-definition video, and requires higher bandwidth during transmission. In the traditional solution, videos with multiple definitions are separately encoded and compressed and transmitted, and the corresponding definition-encoded video is selected according to conditions such as the user bandwidth and the user's display device. This method requires high storage and bandwidth of the server, and cannot be compatible with two or more definition videos in the same code str...
