Based on the display device 200, the user can control the display device 200 to display a preset channel list page through the control device 100, and fig. 5 is a schematic diagram illustrating a display effect of a channel list in the display device 200 according to some embodiments. As shown in fig. 5, a plurality of channels are displayed in the channel list page, and a user can select any one of the channels through the direction key and the confirmation key in the control device 100, so that the display device 200 locks the frequency point corresponding to the channel and then requests the corresponding audio/video data to be played.
The multiple channels preset in the display device 200 are borne on the multiple frequency points, that is, the broadcast operator sends the television programs corresponding to the channels through the code streams sent on the multiple frequency points, and if the code streams are changed when the broadcast operator newly adds, deletes or modifies the channels/frequency points, the corresponding channel list will be changed, which requires the user to synchronously update the channel list preset in the display device 200. At present, when a user needs to update a channel list, a smart television can remind the user in a form of popping up a prompt box, at this moment, the user needs to interrupt watching of a current channel, and manually enters a setting menu to update the channel list, so that the user experience effect is poor. In order to solve the above problems, the present application provides a display device and an automatic channel list updating method in some embodiments.
The channel list automatic update process provided in some embodiments of the present application will be described with reference to the accompanying drawings.
A flow diagram of a method for automatic update of a channel list according to some embodiments is illustrated in fig. 6. The present application provides, in some embodiments, a display device 200, the display device 200 comprising a display 260 and a controller 250, the controller 250 being communicatively coupled to the display 260, the controller being configured to perform the channel list auto-update process of fig. 6. In conjunction with fig. 6, the channel list automatic update process is as follows:
s601: and setting a timer when the display equipment is in a standby state.
In some embodiments, when the user sends the standby instruction to the display apparatus 200, the display apparatus 200 receives the standby instruction and prepares to enter the standby state, and at this time, the display apparatus 200 sets a timer first, so that the channel list update is determined to be appropriate according to the counted seconds of the timer. In one implementation, the user may press a "standby" key on the remote control, causing the display device 200 to enter a standby state. In another implementation, the user may also issue a standby instruction through voice control, for example, a voice instruction that the user continues to input "standby" to the display apparatus 200 after inputting a wakeup word to the display apparatus 200.
In some embodiments, the display apparatus 200 may set a preset wake-up time, where after the preset wake-up time is set, the display apparatus 200 may wake up the background system after the preset wake-up time is reached. For example, the preset wake-up time may be set at midnight time, that is, any time from 1 to 3 am, such as 2 and a half am, during which the user is hardly watching the tv program using the display device 200.
In some embodiments, the display device 200 calculates a time difference according to the preset wake-up time and the current time of the background system, and sets the time difference as the number of seconds counted by the timer. For example, the user sets 1 am as a preset wake-up time, and puts the display apparatus 200 in a standby state at 9 pm, the display apparatus 200 calculates a time difference of 4 hours from 9 pm and one point in the next morning, and takes 4 hours as the number of seconds counted by the timer.
S602: and after the timer finishes counting seconds, controlling a background system to start so that the display equipment starts full-frequency point channel searching to obtain a channel searching result, wherein the channel searching result comprises a network information table version carried by the frequency points.
In some embodiments, when a broadcast operator sends a television program corresponding to each channel through a code stream on multiple frequency points, a Network Information Table (NIT) is carried in the code stream, and the Network Information Table may transmit physical organization Information of multiple code streams through a given Network and characteristic Information of the Network itself, mainly providing Information about the physical Network, and the Network Information Table transmits some Information about the Network and other networks related thereto. When the broadcast operator changes the channel information, the network information table version (NIT version) carried in the code stream is changed at the same time.
In the field of broadcasting and television, the network information table and the frequency points are in a one-to-many relationship, and a plurality of frequency points are covered in the same network, so that the versions of the network information tables corresponding to the frequency points are the same. When the weather becomes poor or the antenna signal is interfered, some frequency points of Terrestrial transmission (Terrestrial) may be locked and unlocked, so that some television programs are sometimes in a channel list and sometimes are not in the channel list, and channel sequencing is changed. If the channel list is updated at this time, the channel list may be lost due to external factors (weather degradation or interference on the antenna signal), so that the user experience is poor. However, the version of the network information table is changed generally because the broadcast operator makes a modification at the time of channel information update, and thus, the display apparatus 200 can avoid this at a high rate by determining whether the broadcast operator makes a channel update through the version of the network information table when performing a full channel search. In addition, when the display device 200 performs a full frequency channel search, even if some frequency points are not locked due to external factors, it is only necessary to lock the network information table versions of other frequency points in the same network.
In some embodiments, the display device 200 starts to count according to a timer, and after the second counting is finished, the display device 200 controls the background system to start without lighting the screen. The display device 200 starts full-frequency-point channel search after being started, and obtains channel search results, where the channel search results include search data such as network information table versions carried by frequency points. For example, the display device 200 may perform a full channel search from the lowest frequency point to the highest frequency point.
S603: and detecting whether the network information table version in the channel searching result is consistent with the network information table version of the corresponding frequency point in the local storage.
In some embodiments, the display device 200 compares the version of the network information table in the obtained channel search result with the version of the network information table at the corresponding frequency point in the local storage, and detects whether the version of the network information table changes.
S604: and if the version of the network information table corresponding to at least one frequency point is changed, updating the channel searching result to a local storage.
In some embodiments, if the display device 200 detects that the version of the network information table corresponding to at least one frequency point has changed, it may represent that the display device 200 detects that the front-end code stream has changed.
In some embodiments, after the display device 200 detects that the front-end code stream has changed, the channel searching result is updated to the local storage to complete the change of the channel list.
In some embodiments, if the version of the network information table in the channel search result is all consistent with the version of the network information table at the corresponding frequency point in the local storage, that is, the display device 200 detects that the front-end code stream has not changed, and the broadcast operator has not changed the channel information, etc., the display device 200 ignores the channel search result this time and does not perform updating.
In some embodiments, before the display device 200 starts a full-frequency channel search, or during the channel search of the display device 200, if the display device 200 receives a power-on instruction input by a user, the display device 200 responds to the power-on instruction at the first time, controls the display device 200 to start, lights up a screen, and cancels the channel search, and at this time, the display device 200 enters a user mode, and may respond to an operation instruction and the like sent by the user through a remote controller, such as playing a television program and the like. Because the broadcast operator does not change the channel information every day, even if the channel information is changed, the display device 200 cannot search part of the television programs, but does not delay the user to watch most of the content, at this moment, the display device 200 may respond to the power-on instruction of the user first, and temporarily abandon the channel list updating.
In some embodiments, after the channel search result is updated, that is, when the display device 200 completes the full channel search and completes the channel list update according to the channel search result, the display device 200 may control the background system to turn off, so that the display device 200 performs a standby state.

After the background system of the display device 200 is started, full frequency point channel searching is started, in the channel searching process, if a starting instruction input by a user is received, channel searching is cancelled, a screen is immediately lightened, and playing is started according to subsequent operation of the user. And summarizing the searching process, and if the starting-up instruction of the user is not received, normally finishing the channel searching process. After the channel searching is completed, the channel searching result is obtained, the display device 299 compares the version of the network information table in the channel searching result with the version of the network information table of the corresponding frequency point in the local storage, and detects whether the version of the network information table is consistent with the version of the network information table of the corresponding frequency point in the local storage. If the version of the network information table corresponding to at least one frequency point changes, the change of the channel information by the broadcast operator is indicated, and further, the channel searching result of the display device 200 is updated to a local storage. If the version of the network information table in the channel search result is completely the same as the version of the network information table at the corresponding frequency point in the local storage, it indicates that the broadcast operator does not update the channel information, and correspondingly, the display device 200 may also cancel the update. After the above process is completed, the display device 200 may close the background system and automatically enter the standby state.
A software functional block diagram of a channel list update service for a display device 200 according to some embodiments is illustrated in fig. 8. As shown in fig. 8, in some embodiments of the present application, the controller 250 is configured with a power-on/power-off module, a channel searching module, a channel list module, and a playing module, through which a channel list update service in the display device 200 is implemented.
