Since the number of channels that can be played by a television is very large, a user may spend a lot of time in the process of searching for a desired channel, which may result in a poor user experience.
In order to solve the above technical problem, an embodiment of the present application provides a channel list display method, which is applied to the display device 200, and in the method, first filtering information is stored in advance, that is, filtering information utilized when a channel is filtered last time is retained, and since a preference of a user for watching the channel does not generally change, when the channel list needs to be displayed again, the first channel list determined by the first filtering information stored in advance is directly displayed on a display, so that time spent by the user when searching for the channel is shortened, and a use experience of the user is improved.
Fig. 5 illustrates a flow chart of a channel list display method provided in accordance with some embodiments. In fig. 5, the method includes:
s1, when receiving the instruction for displaying the channel list, detecting whether there is the first filtering information corresponding to the channel list stored in advance.
In the embodiment of the present application, the instruction for displaying the channel list may be input in various ways.
In one implementation, the instruction for displaying the channel list may be that the user may press a specific key input on the control apparatus 100. Illustratively, the control device 100 is provided with a menu key that a user presses to input an instruction for displaying a channel list. In another implementation, the user may further input an instruction to display the channel list by operating on the user interface through the control device.
In some embodiments, when the user operates the channel source control on the user interface through the control device, the instruction for displaying the channel list is input, so that the channels in the finally displayed channel list are all from the same channel source. Of course, in other embodiments, the channel source control may not be used, so that the channels in the finally displayed channel list are not limited to being from the same channel source.
It should be noted that the channel sources of the channels played by the display device 200 may be various. Illustratively, the channel source includes a satellite signal, a terrestrial signal (cable), a cable signal (antenna), and the like. It is to be understood that the channel sources in the embodiments of the present application are not limited to the above-mentioned channel sources, and may be other channel sources.
In some embodiments, in order to reduce the difficulty of searching channels in the channel list by the user, the channel source control may be set so that the channels in the obtained channel list are only from the source corresponding to the channel source control, and the number of channels in the channel list is reduced, thereby facilitating the user to search channels.
In one example, the instructions for displaying the channel list are entered via the channel source control, which may be entered as per the following example.
Fig. 6 illustrates a user interface diagram provided by some embodiments. In fig. 6, a display entry 600 for a channel source list is displayed, and a user moves a focus to the display entry 600 through the control apparatus 100 and inputs an instruction for displaying the channel source list by pressing a confirmation key on the control apparatus 100.
Fig. 7 illustrates a user interface diagram provided by some embodiments. In response to the instruction for displaying the channel source list, the display is controlled to display the channel source list, where the channel source list 700 includes channel source controls 701 and 703, and the channel source controls correspond to channel sources.
The user may enter an instruction to display a channel list by moving the focus to the channel source control through the control device 100 and pressing a confirmation key on the control device. Referring again to fig. 7, the channel source list includes a first channel source control 701, a second channel source control 702, and a third channel source control 703. The channel source corresponding to the first channel source control 701 may be a satellite signal. The channel source corresponding to the second channel source control 702 may be a terrestrial signal. The channel source corresponding to the third channel source control 703 may be a cable signal. When a user moves a focus to the first channel source control through the control device and presses a confirmation key on the control device, an instruction for displaying a channel list is input, and channels corresponding to the channel controls in the displayed channel list are acquired through satellite signals in response to the instruction for displaying the channel list.
In the embodiment of the application, through the set channel source control, a user can conveniently search channels corresponding to different channel sources. In some embodiments, the channel source control is preset content. When the channel source control is selected, the channel restriction of the channel list is from the same channel source.
In the embodiment of the present application, a display manner of the display entry of the channel source list is not limited. The display portal may be displayed separately on the user interface. Or may be displayed on the user interface along with the channel list. Fig. 8 illustrates a user interface diagram provided by some embodiments, in which an entry 800 is displayed on the user interface together with a channel list 801 corresponding to a currently selected channel source control in fig. 8, so that a user can view channels in the channel list corresponding to the channel source control, and thus, the user can select channels. In some embodiments, when the channel source control is not selected, the channels in the channel list displayed simultaneously with the channel source control may be a channel list corresponding to a preset channel source control.
The user may move the focus to the display portal using the control device and press a confirmation key on the control device. Fig. 9 is a schematic diagram illustrating a user interface provided in some embodiments, where fig. 9 shows a first channel source control 901, a second channel source control 902, and a third channel source control 903. The user can select the first channel source control, the second channel source control and the third channel source control through the control device, and input the instruction of the channel list.
In the embodiment of the application, whether first screening information which is stored in advance and corresponds to the channel list exists is detected. If the first filtering information exists, the filtering information which is set by the user in the past is explained so that the display device displays the channel list which the user wants to watch. At this time, in order to display the channel list again, the original channel list is acquired, which facilitates the subsequent screening of the channel list conforming to the first screening information from the original channel list. The determination of the first screening information is described in detail below. For example, as shown in fig. 9, a user selects a first channel source control 901 through a control device, a channel source corresponding to the first channel source control 901 is a satellite signal, and at this time, it is detected whether first filtering information of a channel list corresponding to the first channel source control 901, which is stored in advance, exists. It is understood that the user may use the first channel source control 901 to view the channel list and then filter out the channel controls of the channels desired to be viewed through the filter list (the process of determining the channel controls through the filter list is described in detail below, and will not be described in detail here).
S2, if the first screening information exists, an original channel list is obtained, and the original channel list comprises at least one piece of first channel information.
In some embodiments, the first channel information includes at least one of first original channel information, second original channel information, and third original channel information.
The step of determining the first original channel information includes: and searching channels through frequency points to determine first original channel information. In the embodiment of the application, the display device may determine first original channel information by searching for a channel at a frequency point, where the first original channel information includes channel information of a digital television program. In the embodiment of the application, before the instruction of the first channel list is displayed, the display device searches channels by using the frequency point to obtain the channel information of the channels which can be played by the display device.
The step of acquiring the second original channel information comprises: and acquiring second original channel information which is stored in a memory in the display equipment in advance.
