Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a channel hiding control method according to an embodiment of the present invention, which may include:
step S11: monitoring whether a version number of a first service group association table carrying a preset mark in a transport stream changes, wherein the first service group association table carries n channel identification information, and the preset mark is used for identifying that n channels corresponding to the n channel identification information carried in the first service group association table need to be hidden;
in the embodiment of the invention, the identification information of the channel to be hidden is sent to the set-top box through a service group association Table (BAT).
The identification information of the channel can uniquely identify one channel, that is, the channel identification information corresponds to the channel one to one.
In a digital television network, a frequency point carries a transport stream, and a transport stream usually carries a plurality of channels. The n channel identification information carried in the first service group association table is identification information of n channels of the multiple channels carried in the one-way transport stream, where n is a positive integer.
Generally, a transport stream may carry a plurality of service group association tables. In this embodiment of the present invention, optionally, the first service group association table may be a service group association table that is independent from other service group association tables in the transport stream.
Step S12: when the version number of the first service group association table is monitored to change, the first service group association table is analyzed from the received transmission stream;
and when the version number of the first service group association table is monitored to be changed, the first service group association table with the latest version is carried in the transmission stream. In the embodiment of the invention, when the version number of the first service group association table is monitored to change, the first service group association table with the latest version is analyzed from the received transmission stream.
Step S13: and hiding n channels corresponding to the n channel identification information in the first service group association table.
The channel hiding control method provided by the embodiment of the invention writes the identification information of the channel to be hidden into a service group association table, and sends the identification information to the set-top box through the transport stream without changing the channel information in the transport stream sent by the front end, and the set-top box hides the channel corresponding to the channel identification information in the service group association table.
In the foregoing embodiment, optionally, after hiding the channel corresponding to the n-channel identification information in the first service group association table, the method may further include:
and marking the hidden channel identification information of the n channels in a channel list stored in the set top box as hidden.
After searching a frequency point for a channel, the set-top box stores a searched channel list, and identification information of each channel carried in a transport stream is stored in the channel list.
After hiding the channels, the identification information of the hidden channels is marked in the channel list so as to distinguish which channels are hidden and which channels are not hidden.
In the foregoing embodiment, optionally, after analyzing the first service group association table, the method may further include:
determining channel identification information marked as hidden but not present in the first service group association table in a channel list stored in the set-top box;
after searching a frequency point for a channel, the set-top box stores a searched channel list, and identification information of each channel carried in a transport stream is stored in the channel list.
In the embodiment of the invention, when the first channel needs to be hidden, the identification information of the first channel is added into the first service group association table, and the version number of the first service group association table is updated. And when the first channel needs to be displayed again, deleting the identification information of the first channel from the first service group association table, and updating the version number of the first service group association table. Therefore, after the identification information of the first channel is deleted from the first service group association table, the identification information of the first channel is marked as hidden in the channel list stored by the set-top box before the first channel is not displayed.
And displaying the determined channels marked as hidden but not corresponding to the channel identification information in the first service group association table.
In this embodiment, when the hidden first channel needs to be displayed again, only the first channel needs to be deleted from the first service group association table, and the version number of the first service group association table is updated, which is simple in operation and easy to implement.
In the above embodiment, optionally, after determining, in the channel list stored in the set top box, that the channel is marked as hidden but does not exist in the channel identification information in the first service group association table, the method may further include:
and marking the channel identification information which is determined to be hidden but not existed in the first service group association table in a channel list stored in the set top box as display.
In the embodiment of the present invention, after determining that the channel identifier information is marked as hidden but not present in the first service group association table in the channel list stored in the set top box, in addition to displaying the channel corresponding to the channel identifier information that is marked as hidden but not present in the first service group association table, the channel identifier information that is determined to be hidden but not present in the first service group association table in the channel list stored in the set top box is marked as displayed.
That is, if the identification information of the first channel is marked as hidden in the channel list stored in the set-top box but does not exist in the first service group association table, which indicates that the first channel is hidden before, now it is not hidden but displayed, at this time, in addition to displaying the first channel, the identification information of the first channel in the first service group association table is marked as displayed.
The way of marking display may be: deleting the hidden mark, namely, regarding the mark as display without the hidden mark; alternatively, the hidden mark is replaced by a revealed mark, i.e. the revealed mark and the hidden mark are two different marks.
