Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Moreover, due to the hardware structure, the hardware system of the conventional display device only supports one hard decoding resource, and usually can support video decoding with a maximum resolution of 4K, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resource (usually a GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. a CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the picture is blocked or unsmooth. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multiple paths of video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

Based on the consideration of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept of the present application will be described first with reference to the drawings. It should be noted that the following descriptions of the concepts are only intended to make the contents of the present application more easily understood, and do not represent limitations on the scope of the present application.
