Description
Technical Field
The present invention relates to the field of display technologies, and in particular, to a display method, an embedded terminal, and a computer-readable storage medium.
Background
With the rapid development of internet and multimedia technologies, more and more users are beginning to use internet-based video conferencing. Usually, through a mobile phone, a computer or a conference terminal, a user can access the internet at different times and different places to realize video conference.
The development of internet technology also brings new changes to video conferences, and high-definition video conferences and even ultra-high-definition video conferences are more and more favored by users. 720P, 1080P video conferencing has become very popular, even with some scenes 4K of video already going to the user.
The higher the definition of the video conference, the larger the amount of encoding and compressing operations of the video image. The resolution of 4K video is increased by 4 times compared with the original 1080P video, and meanwhile, the video frame rate of 30 frames per second cannot meet the requirement of a user, and the video frame rate of 60 frames per second is also coming. High resolution and high frame rate mean that the background needs to process more data. The operation amount of the coding is increased by 4 times from the original 1080P30 frame video to the 4K30 frame video. These problems make the original software-based codec server unsatisfactory if the complexity of replacing the original H264 encoder with HEVC is increased more than 4 times. It is therefore necessary to select a hardware terminal for hardware encoding and decoding services of video images in a conference.
The inventor finds that the adoption of the hardware terminal can not meet certain display requirements of the video conference in the aspect of interface display in the process of realizing the invention. Specifically, in a video conference, it is generally necessary to superimpose interface elements such as a conference name, a status, a time date, and the like in a video to be output to a user as a display interface. The existing hardware terminal is implemented by a method based on region management. The hardware terminal is fixedly designed with a limited number of areas, when interface elements need to be overlapped, a user is required to create the size of one or more areas in advance and overlap the areas into a certain channel, and the interface elements can be overlapped into a video when the channel is scheduled. This approach has the biggest problem that the total number of regions has a number limit, with a maximum of 8, i.e. there are only 8 regions that can be replaced. For general applications, 8-region text or picture replacement may be sufficient, but for video conferences, the text part and the picture part may be more than ten, and the existing mode cannot meet the multi-interface display requirement of the video conferences. When the number of interface elements is too large, the regional resources of the hardware terminal cannot meet the number of the interface elements, and the requirements for dynamically displaying the multi-interface elements and the video stream cannot be met at the same time.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
