Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes the present embodiment in detail, taking the display terminal as an example of an intelligent electronic device.
Fig. 2 is a flowchart of a method of displaying a list of signal sources. As shown in fig. 2, an embodiment of the present application provides a method for displaying a signal source list, which is applied to an intelligent television, and includes the following steps:
and 11, when the intelligent television plays the signal source content, recording the channel information of the current playing channel of the signal source.
Here, the signal source is divided into two types, a direct broadcast type signal source, such as an analog television, a cable digital television, a terrestrial digital television, or other format digital television, and a non-direct broadcast type signal source, such as a set-top box connected through an HDMI or an audio-video interface.
Specifically, when the smart television is switched to a live broadcast type signal source and plays a certain channel, directly recording channel information of the channel, such as channel number, channel name, channel logo and other data; meanwhile, after the user switches the channel under the signal source, the channel information of the switched channel needs to be recorded in real time. That is, the channel information of the channels sequentially played by the signal source is recorded in real time, for example, when the program in the first channel is currently played, the channel information of the first channel is recorded; if the user switches to the second channel to watch the program in the second channel, recording the channel information of the second channel; the channel information can be stored in the smart television in a list form.
When the smart television is switched to a signal source of a non-live type, the signal source playing content is controlled by the set top box, and the smart television is only used as a display screen to display the signal source playing content, so that the smart television cannot acquire channel information of a signal source playing channel. In the implementation, screenshot is carried out on a signal picture provided by the signal source, and then image recognition is carried out on the screenshot so as to identify a channel station logo pattern contained in the signal picture; and comparing the pattern of the channel station caption with a preset channel station caption pattern, and recording channel information corresponding to the identified pattern of the channel station caption when the comparison is successful. Here, when the user operates the set-top box to switch channels, it is also necessary to record channel information of broadcast channels corresponding to signal pictures sequentially provided by the signal source in real time, and the channel information may be stored in the smart television in a list form.
And step 12, receiving an input instruction for displaying the signal source list.
Here, when a user needs to switch from one signal source to another signal source, the "signal source" button on the remote controller may be pressed, and the smart television receives a user input instruction for displaying a signal source list. Or when the user presses a 'home page' key on the remote controller, the smart television receives a user input instruction for displaying a home page panel, the home page panel is displayed, the home page panel comprises a display area of the signal source list, and the smart television also receives the user input instruction for displaying the signal source list.
And step 14, reading the channel information played by the signal source with the signal input, and inquiring the program information currently played by the channel in the channel information.
And step 15, acquiring a signal source name and a signal source icon which are connected with the intelligent television.
Here, the smart tv first detects whether signals are input to each currently connected signal source. When it is determined that the signal source has a signal input, the channel information played by the signal source itself is read from the channel information of the playing channel of the signal source recorded in advance in step 11. The channel information may be channel information of a channel being played by the signal source when the smart television last quits the signal source, that is, channel information in a last record in a channel information list of a channel played by the signal source, which is recorded in advance in step 11, so that a user continues to watch a program of the channel; or, the channel information may be channel information of a channel with the highest playing frequency of the signal source, that is, channel information with the largest recording frequency in a channel information list of the playing channel of the signal source pre-recorded in step 11, so as to provide the playing content of the favorite channel of the user with the highest probability; of course, the channel information may also be the channel information of a fixed channel in the broadcast channels of the signal source.
Further, after reading the channel information corresponding to the signal source, the Program information played at the current time corresponding to the channel included in the channel information is queried from EPG (Electronic Program Guide) information stored in a memory of the smart television. Of course, in the EPG information provided on the background server corresponding to the smart television, the program information played at the current time corresponding to the channel included in the channel information may be queried online. Here, the program information may be data such as a program name, program start and end times, a program genre, and a program playing progress.
In addition, whether a signal source connected with the intelligent television has signal input or not, a signal source name and a signal source icon corresponding to the signal source are read from the intelligent television system to be displayed in a signal source list.
And step 16, generating and displaying a signal source list according to the item data corresponding to the signal sources acquired in the steps 14 and 15.
Specifically, for the signal source with the signal input, the channel information read in step 14 and played by the signal source itself, the program information currently played by the channel in the channel information, and the signal source name and the signal source icon read in step 15 are used as the item data corresponding to the signal source with the signal input. For a signal source without signal input, only the signal source name and the signal source icon read in step 15 are used as the item data corresponding to the signal source without signal input. And finally, displaying the item data corresponding to each signal source on the intelligent television in a list form.
For example, fig. 3 is a schematic diagram of a signal source list display provided in this embodiment, where, for an analog television signal source and a signal source connected through an HDMI1 interface, only a signal source icon and a signal source name corresponding to the analog television signal source are displayed in signal source item data, and it also indicates that there is no signal input currently in the two signal sources connected to the smart television. For a cable digital television signal source, the signal source item data not only displays a corresponding signal source icon 3.1 and a signal source name 3.2, but also displays channel information played by the signal source item data: CCTV1 channel and channel logo 3.3, and program information of the current time broadcast of the CCTV1 channel: news simulcast and the program playing time are 3.4, and the current playing progress of the program is 3.5; and simultaneously, the signal source connected with the intelligent television is indicated to have signal input currently.
Here, whether the signal source has a signal input or not may be displayed differently in the signal source list, so that the user can know whether the signal source has a signal input or not. For example, the item data corresponding to the signal source with the signal input is displayed in a normal font, and the item data corresponding to the signal source without the signal input is displayed in a font semi-transparent or icon gray.
In the above example, by adding, to the item data corresponding to each signal source of the signal source list: the channel information played by the signal source and the program information currently played by the channel corresponding to the channel information can be visually known by a user in a signal source list interface, the playing content currently provided by each signal source can be conveniently and approximately previewed by the user before the signal source is switched, the playing content provided by the target signal source can be known without the user operating a remote controller to switch to the target signal source, the operation steps of the user are reduced, and the user experience is improved.
