In one embodiment of the invention, the channel selection interface 200 presents a sequence 3, 1, 2 of a plurality of selected channels 201, 202, 205 (as shown in FIG. 3). For example, since the earlier selected channel is more important to the user, the calculation logic of the layout configuration may be, for example, that the image frame of the first selected channel is not smaller than the image frame of the later selected channel, and the corresponding image frames are arranged from left to right and from top to bottom in the layout according to the selection sequence, but the invention is not limited to this example.
Processor 120 then outputs a plurality of images (e.g.,. o,) of the plurality of selected channels 201, 202, 205 to a corresponding panel 300 (shown in fig. 3) of display 140.
In an embodiment of the present invention, the exclusive channel is described as an example that can be selected only one, but the present invention is not limited thereto. The processor 120 determines whether at least one of the selected channels 201, 202, 205 is an exclusive channel, and if none of the selected channels is selected or only a single exclusive channel is selected, the processor 120 determines whether a non-exclusive channel of the selected channels 201, 202, 205 is repeatedly selected, and if so, the processor removes one of the repeatedly selected channels (e.g., removes the previously selected channel, and performs a complementary adjustment of the ordering). If not, the processor 120 arranges the sequence according to the sequence selected by the user.
Furthermore, in an embodiment of the invention, if two selected channels of the plurality of selected channels 201, 202, 205 are exclusive channels, the processor 120 removes one of the two selected channels (e.g., removes the previous exclusive channel option, performs adjustment sorting to the previous iteration, and adds the selected exclusive channel), and the number of the selected exclusive channels can be adjusted on demand, but is not limited thereto.
To further describe the operation method of the channel selection and image display system, please refer to fig. 1 to 4, and fig. 4 is a flowchart of a method 400 for channel selection and image display according to an embodiment of the invention.

DELTA.,. and.,) for channels 201, 202, 203, 205 with signals in the channels 201-206 selected by the user, and presents a predetermined object 210 (e.g., animation, no-signal, or other text and/or icon) for channels 204, 206 with no signals in the channels 201-206 selected by the user, thereby reminding the user and preventing the user from selecting the channels by mistake.
Then, the user can select the channels to be displayed sequentially through the input device 150 according to the importance. In step S402, corresponding layouts are configured according to the sequence and number of the selected channels 201, 202, 205 in the channels 201 to 206. In one embodiment of the invention, the channel selection interface 200 presents a sequence 3, 1, 2 of a plurality of selected channels 201, 202, 205 (as shown in FIG. 3). For example, since the earlier selected channel is more important to the user, the calculation logic of the layout may be, for example, the frame of the first selected channel is greater than or at least equal to the frame of the later selected channel, but the invention is not limited thereto. In one embodiment, the selected channels or the selected sequence can be presented or marked on the corresponding layouts, so that the user can more intuitively know which layout corresponds to which selected channel.
In step S403, a plurality of images (e.g., O,. quad) of a plurality of selected channels 201, 202, 205 are output to a corresponding panel 300 (shown in FIG. 3) of the display 140.
In the method 400 for channel selection and image display, it is determined whether at least one of the selected channels 201, 202, 205 is an exclusive channel, if none of the selected channels is selected or only a single exclusive channel is selected, it is determined whether a non-exclusive channel of the selected channels 201, 202, 205 is repeatedly selected, and if so, one of the selected channels is removed (e.g., removing the previously selected channel, and adjusting the sequence by adding up). Otherwise, if not, the sequence is arranged according to the sequence selected by the user.
In the method 400 for channel selection and video display, if two selected channels of the plurality of selected channels 201, 202, 205 are exclusive channels, one of the two selected channels is removed (e.g., the previous exclusive channel is removed, and the selected exclusive channel is added after the previous exclusive channel is adjusted and sorted in a forward complement manner), so that the number of the exclusive channels that can be selected can be adjusted as needed, but is not limited thereto.
In conclusion, compared with the prior art, the technical scheme of the invention has obvious advantages and beneficial effects. By the technical scheme of the invention, a wired or/and wireless signal source can be integrated, the number and the sequence of clicking are recorded in the background while a user clicks a channel, and a corresponding layout is generated according to two items of data so as to meet the display requirement. Therefore, wired/wireless signal sources can be simultaneously supported, extra complicated setting is not needed, and the layout is logically calculated and configured and the sources are output to corresponding pictures. The convenience of use is improved, and if the output source or the number can be changed in one step, the operation steps of a user are reduced to achieve the same effect.
