Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
The terms "first" and "second," etc. in this disclosure are used to distinguish between different objects, rather than to describe a particular order of objects. For example, the first processing result, the second processing result, and the like are used to distinguish different processing results, and are not used to describe a specific order of the processing results.
The external device is mainly a device which can be connected with a display device so as to achieve the purposes of surfing the internet, watching network television programs or playing digital video discs and the like. In general, the external device may be a set-top box, a DVD, and various brands of network boxes, and the specific type of the external device is not limited in the embodiment of the present disclosure. Through the interaction of the external device and the display device, the user can have richer experience.
Currently, display devices of various brands generally support a key transmission function of a Computational Electronics Control (CEC), and key information received by the display device can be transmitted to an external device through the key transmission function, so as to achieve an effect of controlling keys corresponding to the external device, for example, controlling play, pause, up, down, left, right, and other keys of the external device.
Fig. 1A is a schematic view of an operation scenario among a display device, an external device, and a control device according to one or more embodiments of the present disclosure. As shown in fig. 1A, an external device 201 accesses a display device 200, and a user can view content in the external device 201 through the display device 200.
