Embodiment 1
[0031] A sending process of high-definition video conference images, comprising the following steps:
[0032] In the first step, the sending end collects image data to obtain 50 frames / second or 60 frames / second image data;
[0033] In this step, the adjacent two frames of image data collected are as shown in Figure 1, wherein, Figure 1 (a) is the odd frame image data collected, and Figure 1 (b) is the next frame adjacent to the odd frame image data Even frame image data;
[0034] The second step is to extract video data interlacedly from a frame of image data collected (hereinafter referred to as the first image data frame), and from the next frame of image data adjacent to the image data frame (hereinafter referred to as the second image data frame) frame) to extract video data interlaced;
[0035] Preferably, extract odd-numbered row data from the odd-numbered frame image data of collection, namely extract the data of 1, 3, 5, 7...etc. row, after extracting as shown in Fi...
Embodiment 2
[0040] A transmission process of high-definition conference video images, including sending and receiving two parts, the transmission process, including the following steps, wherein, the operation of the sending end is exactly the same as the sending process described in Embodiment 1, so only a brief description:
[0041] A, the sending end collects image data, and obtains 50 frames / second or 60 frames / second image data;
[0042] B, extract video data interlacedly from the first image data frame collected, and extract video data interlacedly from the second image data frame adjacent to the image data frame;
[0043] B. Combining the extracted half-frame data into one frame of data, and sending it to the terminal after encoding;
[0044] C. The terminal receives the image data frame, and obtains the composite frame after decoding, and extracts the video data in two adjacent frames of image data from the composite frame according to the set rules;
[0045] In this step, the pro...

Abstract
The invention discloses a method for transmitting high-definition video conference images, which belongs to the field of high-definition video conference. The method for transmitting high-definition video conference images comprises that: a transmitting terminal interlacedly extracts image data from the collected one frame of image data, interlacedly extracts the image data from a next frame of image data which are adjacent to the frame of image data, uses the extracted video data to generate and synthesize frame data according to preset rules, codes the frame data and sends the frame data toa receiving terminal. By implementing the technical scheme provided by the invention, an image display effect of 50 frames per second or 60 frames per second is obtained by a transmission technology of 25 frames per second or 30 frames per second, thereby ensuring the video conference users can receive smooth high-definition pictures and improve visual experiences of the users.
Description
technical field [0001] The invention belongs to the field of high-definition conference television, and in particular relates to a high-definition conference television image transmission method. Background technique [0002] At present, there are many standards in the field of high-definition video conferencing, such as 720P, 1080I and 1080P. Among them, for 720P and 1080P, from the perspective of acquisition equipment and display equipment, there are only two standards for frame frequency, namely 50 frames per second and 60 frames per second, and the actual codec frame rate is only the acquisition equipment and display equipment. Half, i.e. 25 fps and 30 fps. [0003] The traditional method is to collect image data, extract half of the data frames for encoding, and after receiving the data frames for decoding, the terminal repeats the frame rate twice and then displays it. However, this approach leads to an actual frame rate of only 25 frames per second or 30 frames per ...
