Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments These are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The terms "first" and "second" in the specification, claims, and drawings of this application are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence.

This application is mainly directed to a display device with a dual-system and dual-display structure, that is, a display device with a first controller (a first hardware system), a second controller (a second hardware system), a first display screen, and a second display screen.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate the connection of different peripheral devices or cables to achieve corresponding functions. When a high-resolution camera is connected to the interface of the display device, if the hardware system of the display device does not have the hardware interface of the high-pixel camera that receives the source code, it will cause the data received by the camera to be unable to present the data received by the camera to the display of the display device. On the screen.

Moreover, due to the hardware structure, the hardware system of traditional display devices only supports one hard decoding resource, and usually only supports 4K resolution video decoding. Therefore, when you want to realize the video chat while watching Internet TV, in order not to reduce The definition of the network video picture requires the use of hard decoding resources (usually the GPU in the hardware system) to decode the network video. In this case, the general-purpose processor (such as CPU) in the hardware system can only be used to decode the video. The video chat screen is processed by soft decoding.

Using soft decoding to process the video chat screen will greatly increase the data processing burden on the CPU. When the data processing burden on the CPU is too heavy, the picture may freeze or become unsmooth. In some embodiments, due to the data processing capability of the CPU, when the CPU soft decoding is used to process the video chat screen, it is usually impossible to achieve multi-channel video calls. When the user wants to simultaneously video chat with multiple other users in the same chat scene At times, access will be blocked.

Based on the above considerations, in order to overcome the above shortcomings, this application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one local video).
