Therefore, the embodiment of the application can modify the sequence of the live channel information items and the network channel information items, so that part or all of the network channel information items are arranged before the live channel information items or are interspersed in the live channel information items.

The user can change the channel list into the modification mode after a series of operations by using the control device, and in the modification mode, the user can move the selector by inputting an instruction, select the item needing to modify the sequence, modify the channel serial number of the item, move the selector after modification and confirm the modification operation. And rearranging the items on the channel list according to the modified channel serial number. For example, if the channel number 4001 of the entry 425 in fig. 2 is changed to 2, the entry 425 moves to the location of the entry 422 with the original channel number 2, the channel numbers of the

original entries

422 and 424 are sequentially incremented by one, and the location is sequentially shifted down by one, see fig. 3.

Fig. 4 illustrates a flowchart of a method of displaying a channel list.

In connection with the method shown in FIG. 4, the method includes steps S41-S42:

s41, responding to the instruction of the instruction display channel list input by the user, acquiring first channel information from the broadcast signal and second channel information from the external server; the channel information at least comprises a channel number, a channel name and a mark field indicating a channel serial number;

for example, the user may input an instruction indicating that a channel list is displayed by pressing a specific key on the control apparatus.

It should be noted that the first channel information and the second channel information are respectively stored in mutually independent database tables. The first channel information is derived from broadcast signals and is live channel information; the second channel information originates from an external server and is network channel information.

For example, the first channel information is shown in table 1, and the second channel information is shown in table 2.

TABLE 1

TABLE 2

Specifically, each channel is provided with a unique channel number. When a user selects to view a playing interface of a channel corresponding to certain first channel information or second channel information, the channel number is determined through the unique channel number. The mark field is a serial number of the indicating channel in the channel list, which is stored in a database table and located in the background, the channel serial number is a serial number of the indicating channel in the channel list, which is located in the foreground, and the content of the channel serial number is the same as that of the mark field in an unmodified state.

And S42, generating and displaying a channel list according to the first channel information and the second channel information.

Specifically, the content of the channel displayed on the channel list includes a channel number and a channel name, and the channel number is determined by a mark field in the first channel information and the second channel information. The channel list in the embodiment of the application can simultaneously display the channels in the first channel information and the second channel information, namely, the channels comprise live channels and network channels, so that a user can browse all the channels when viewing the channel list.

The existing display modes of the live channel and the network channel are respectively visible only by opening different applications. For example, referring to fig. 5 and 6, the channel list 42 shown in fig. 5 includes only live channels, and the channel list 42 shown in fig. 6 includes only network channels. According to the embodiment of the application, the live channels and the network channels are displayed in the same channel list, referring to fig. 2, a user can conveniently open an application to see all the channels, and the user can select and watch the channel playing interfaces corresponding to the live channels and the network channels in one channel list through the control device, so that the user experience is improved.

The user can switch between the live channel and the network channel according to the past operation modes, such as controlling channel +/-, up/down keys on the device and directly inputting the channel number.

Specifically, in conjunction with the method shown in fig. 7, step S42 may include the following steps:

s421, generating a first list according to the sequence of the channel numbers corresponding to the mark fields from small to large of the channels in the first channel information;

s422, inserting the channels in the second channel information into the first list one by one according to the sequence of the channel serial numbers corresponding to the marking fields from small to large, and generating a channel list.

Specifically, the channels on the channel list are arranged in the order of the channel numbers from small to large, and in order not to affect the live channel data and the service logic, in an actual operation, the channels in the first channel information, that is, the channels in the live channel information, are generated into the first list in the order of the channel numbers corresponding to the mark fields from small to large. And then, inserting the channels in the second channel information into the first list one by one according to the sequence of the channel numbers corresponding to the marking fields from small to large, finally, collecting all the channels in the first channel information and the channels in the second channel information into the first list, and generating a channel list.

By way of example, the channels in the first channel information of table 1 and the channels in the second channel information of table 2 are grouped into a first list: firstly, first channel information is arranged and added into a first list according to the sequence from small to large of channel numbers corresponding to a mark field, then, a channel with a channel number 4001 is added into the first list according to the size of the channel number, at this time, the channel with the channel number 4001 is arranged behind a channel with a channel number 4, then, the channel with the channel number 4002 is added into the first list, at this time, the channel with the channel number 4002 is arranged behind the channel with the channel number 4001, when all the channels are added into the first list, see table 3, table 3 is the first list, and the channel list displayed on a display is shown in fig. 2.

Fig. 8-9 illustrate flow charts of another method of displaying a channel list.

In connection with the method shown in FIG. 8, the method includes steps S61-S62:

s61, responding to the channel selection instruction, selecting at least one second channel, wherein the second channel is derived from the second channel information;

specifically, when a channel list generated by including the first channel information and the second channel information is already displayed on the display, if the user needs to modify the arrangement order of the channels, a channel selection instruction is transmitted by the control device in a modifiable mode of the channel list. The user may select at least one second channel and modify the channel number of the second channel. After the user finishes modifying, the selector can be moved, and a moving instruction is sent.

S62, responding to the moving instruction, modifying the channel serial number of the second channel in the second channel information, moving the second channel to the front of the first channel corresponding to the channel serial number originally according to the channel serial number of the second channel, and displaying the updated channel list, wherein the first channel is derived from the first channel information.

In connection with the method illustrated in FIG. 9, in some embodiments, the method further includes S63-S64:

s63, modifying channel serial numbers corresponding to the first channel and the subsequent channels in the first channel information, and generating a first list according to the channel serial numbers in the modified first channel information;

and S64, sequentially adding the channels in the second channel information into the first list according to the modified channel serial numbers in the second channel information, and generating an updated channel list.

For example, when the selector selects the second channel corresponding to item 425 in fig. 2 and the move command is input, the controller changes the channel number of the second channel from 4001 to 2, and the second channel information is changed from table 2 to table 4.

TABLE 4

Tag field	Channel number	Channel name

		4003	OTT 3

For another example, based on the channel list shown in fig. 3, the controller changes the channel number of the second channel corresponding to the item 427 from 4003 to 2 based on the user input, and the second channel information is changed from table 4 to table 7. The flag field of the channel having the original flag field of 2 is changed to 3 in table 4.

TABLE 7

Tag field	Channel number	Channel name
				3	4001	OTT1
4002	4002	OTT 2
			2	4003	OTT 3

At this time, the first channel information of table 5 and the first list of table 6 are also changed, as shown in table 8 and table 9. In table 5, the mark field of the channel in the first channel information is modified according to the channel number of the channel in the modified second channel information. The mark fields of the channel with the original mark field of 2 and the subsequent channels are increased by 1, and the corresponding channel number displayed on the display is increased by 1, thereby forming table 8. Next, a first list is generated in the order of the first channel numbers in table 8, and the second channels in table 7 are added to the first list in the order of the channel list numbers from small to large to form table 9, where the channel list displayed on the display of table 9 is shown in fig. 10.
