Example Embodiment

[0128] Example one, as Figure 4 As shown, according to the image division information, dividing the frame picture in the image data into a first area and a second area includes:

[0129] Step 401, according to the image division information, determine an image data selection area in a display unit that displays the image data;

[0130] Step 402 , the image data selection area corresponds to the first area, and the part from which the first area is removed in each frame of image is the second area.

[0131] In this embodiment, the boundary information of the first region determined in the frame picture of the first frame is used as a selection box for selecting the first data. The image data in the box is used as the first data; the image data outside the selection box is used as the second data.

Example Embodiment

[0132] Embodiment two, as Figure 5 As shown, according to the image division information, dividing the frame picture in the image data into a first area and a second area includes:

[0133] Step 501, according to the image division information, determine an image data selection area in a display unit that displays the image data;

[0134] Step 502, determining that the image data corresponding to the image data selection area in the current frame image data is an image data object;

[0135] Step 503: Match the image data object with each frame of image data in the image data, the area matched with the image data object corresponds to the first area, and the part of each frame of image that removes the first area is the second area. area.

[0136] In this embodiment, the image data in the first region determined in the frame picture of the first frame is used as a template (ie, an image data object). During the transmission of subsequent frame images, the image data object ...

Abstract

The invention discloses a multimedia data transmission method and electronic equipment. Before a first terminal transmits multimedia data to a second terminal, the method includes the steps that the multimedia data to be transmitted are partitioned into first data and second data according to preset data partitioning strategies; the first data are processed in a first processing mode to obtain third data, and the second data are processed in a second processing mode to obtain fourth data, wherein the total data volume of the third data and the fourth data is smaller than that of the first dada and the second data, and the first processing mode is different from the second processing mode; the third data and the fourth data are transmitted to the second terminal so that the third data and the fourth data can be combined by the second terminal according to combination strategies corresponding to the partitioning strategies. The multimedia data transmission method and the electronic equipment can decrease the transmission data volume and also can keep the video quality of a watched area.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a multimedia data transmission method and electronic equipment. Background technique [0002] At present, video technology has a wide range of applications, such as online video conferencing, online video e-commerce, online government affairs, online shopping, online schools, telemedicine, online seminars, online exhibition halls, personal online chat, visual consultation, etc. business. [0003] For example, in the existing living environment, when user A makes a Mobile or IM video call with user B, in the case of limited communication bandwidth, the higher the definition, the greater the amount of data transmission required, which will make the transmission smoother The worse it is, the larger the amount of data for the same transmission time. [0004] When solving the above-mentioned problems in the prior art, a method of reducing the resolution of the video s...
