Technical Field

The present invention relates to the field of display technologies, and in particular, to a content display method and a display device.

Background

Currently, when a user watches a digital television, the following steps are generally adopted to select a program channel for watching: 1) the method comprises the steps of checking the program name played by each channel in a channel list, judging the type of a program according to the program name, and further judging whether the program is a program which the user wants to watch; 2) selecting a channel which is in line with the watching expectation by pressing a key on the remote controller to trigger channel changing, thereby carrying out actual watching; 3) after actual watching, if the current program content is interested, the watching is continued, and if the current program content is not interested, the channel is changed by pressing a channel increasing/decreasing key.

The current live television signals are basically transmitted to a television host end through a broadcast antenna, a cable or a satellite channel after being encapsulated by a TS (Transport Stream packet) code Stream. After receiving the real-time television signal, the television host firstly locks the signal of a specific frequency through a tuner on the television, converts the signal into an intermediate frequency signal after processing such as frequency mixing, filtering and the like, sends the intermediate frequency signal to a demodulator for decoding processing such as demodulation/descrambling/de-interleaving and the like, restores a TS code stream, and sends the TS code stream to a controller for playing processing.

By setting tuner parameters to scan each frequency one by one, and then identifying and processing through a demodulator and a controller, the television can lock all channel information in the current signal and store the channel information as a channel list, and a subsequent user can check program information of a specific channel based on the channel list.

Because the tuner can only lock a signal of one frequency at the same time (the oscillation frequency of the local oscillation circuit is set to be the same as the target signal frequency), a Television with only a single tuner can intelligently analyze program information transmitted under one frequency point at the same time (a Digital Television (DTV) can contain a plurality of channels under the same frequency point). For a television with a plurality of tuners, television signals of a plurality of frequency points can be locked at the same moment, and programs under the frequency points can be played simultaneously after being processed by the controller, so that the functions of Picture In Picture (PIP) and the like are realized, and a user can watch a plurality of program information at the same time.

Fig. 2A to 2G are schematic diagrams exemplarily showing one GUI400 provided by the display apparatus 200 by operating the control device 100.

In fig. 2A, a program content playing page 41 may be displayed after the user opens the display device. When the user presses a channel list key on the control device, the display device displays a channel list 41-1 in the program content playback page in response to an instruction corresponding to the key value of the key. The channel list contains a number of channel options: channel 1 option to channel 8 option. At this time, the focus is located on the channel 1 option providing the program content in the program content playing page, and the channel name of the channel 1 option being played is displayed at the same time in the upper left corner of the program content playing page.

In fig. 2A, when the user presses a direction key on the control apparatus, the display device controls the focus to move from channel 1 shown in fig. 2A to channel 2 shown in fig. 2B in response to an instruction corresponding to the key value of the key. Meanwhile, a small window 41-2 is displayed at one side of the channel list. The program content provided by channel 2 is displayed in the small window shown in fig. 2B.

In fig. 2B, when the user presses the confirmation key on the control apparatus, as shown in fig. 2C, the display device responds to the instruction corresponding to the key value of the key, and the program content provided by channel 1 displayed on the display is switched to the program content provided by channel 2, while the small window is no longer displayed.

The analysis of TV code stream signals is carried out based on frequency points, and for a display device of a single tuner, only one frequency point can be locked at the same time, and at the moment, the program picture information of other channels under the same frequency point can only be synchronously analyzed. For the display equipment of the single tuner, only one frequency point can be locked at the same time, and only the program picture information of other channels under the same frequency point can be synchronously analyzed. Therefore, if the channel options in the channel list do not belong to the same frequency point of the currently played channel, the program content cannot be previewed in the small window.

For example, in fig. 2D, the content displayed on the current program content playing page is the program content provided by the channel 1 option, and the channel 2 and the channel 6 are at the same frequency point as the channel 1, and then the preview identifier (such as the star shown in fig. 2D as an example) is displayed on the channel 2 and the channel 6. And other channels which are not in the same frequency point with the channel 1 do not display the preview identification. In fig. 2D, when the user inputs an instruction to move the focus by pressing the direction key of the control means, the display apparatus controls the focus to move from the channel 1 option to the channel 2 option in response to the instruction. As shown in fig. 2E, since the channel 2 and the channel 1 are at the same frequency point and are simultaneously displayed with the preview identifier, a small window is displayed at one side of the channel list for displaying the program content provided by the channel 2 option. Similarly, if the focus of the channel list is moved to the channel 6 option, the program content provided by the channel 6 option is displayed in the small window.

In contrast, in fig. 2D, since channels 3, 4, 5, and 7 and channel 8 are not located at the same frequency point as channel 1, no preview id is displayed on these channel options. When the user inputs an instruction to move the focus by pressing the direction keys of the control device, the display apparatus controls the focus to move from the channel 1 option to the channel 3 option in response to the instruction. As shown in fig. 2F, one side of the channel list no longer displays a small window. Through the embodiment, the user can intuitively judge which program contents of the channel options can be previewed, and the user can select the channel more conveniently.

In some embodiments, as shown in fig. 2D, the content currently being displayed is the program content of channel 1. The channel option for displaying the preview identifier in the channel list is a channel with the same frequency point as that of the channel 1: channel 2 and channel 6. In fig. 2D, when the user presses the direction key on the control device, as shown in fig. 2F, the display apparatus controls the focus to move from channel 1 to channel 3 in response to an instruction corresponding to the key value of the key. When the user presses the OK/OK key on the control device, the display device controls the display to switch the program content displayed from the content provided on channel 1 to the content provided on channel 3 in response to an instruction corresponding to the key value of the key, as shown in fig. 2G. The channel name shown in the upper left corner of the display is also changed to the name of channel 3. At the same time, the preview identification displayed on channel 2 and channel 6 options is dismissed. And the preview mark is displayed on the channel options of the channel 4 and the channel 8 which have the same frequency point with the channel 3.

As shown in fig. 3, the content display method of the display device with a single tuner is implemented as a logic diagram. The specific implementation logic process of the above embodiment is as follows:

step one, when a user presses a channel searching key on a control device, a display device responds to an instruction corresponding to a key value of the key to complete channel searching, stores searched channels, synchronously stores channel information corresponding to each channel in a channel list, and is used for carrying out comparison and judgment on common frequency points.

And step two, when the user presses the confirmation key on the control device, the display equipment responds to the instruction corresponding to the key value of the key, and the channel is selected for playing. When a user presses a channel list key on the control device, the display device calls a channel list in response to an instruction corresponding to the key value of the key. Meanwhile, frequency point information of a current playing channel is obtained, all channels in the channel list are traversed, and channels with the same frequency point are searched. And adding a display preview identifier on the channel option with the same frequency point as the currently played channel to prompt a user that the channel can preview the program content.

And step three, when the user presses the direction key on the control device, the display equipment responds to the instruction corresponding to the key value of the key and controls the focus to move among different channel options. And when the control focus moves to the channel option with the preview identification, synchronously calling a program preview interface, and displaying the program content being played by the channel through a small window at one side of the channel list.

And step four, when the user presses a direction key on the control device, the display equipment responds to an instruction corresponding to the key value of the key, controls the focus to move from the channel option containing the preview identification to the channel option not containing the preview identification, and cancels the display in a small window displayed at one side of the channel list.

In some embodiments, the display device with the double tuners can resolve channel program picture information at any frequency point based on the two tuners because the two frequency points can be locked simultaneously.

As shown in fig. 4, the content display method of the display device with dual tuners implements a logic diagram. The specific implementation logic process is as follows: the display device has a master/slave dual tuner, and is simultaneously connected to signal lines of the same transmission mode and content, such as DVB-T (Digital Video Broadcasting-television), DVB-C (Digital Video Broadcasting-Cable), or DVB-S (Digital Video Broadcasting-Satellite). The two tuners can receive the same signal synchronously and can process in parallel.

Step one, when a user presses a channel searching key on the control device, the display device responds to an instruction corresponding to the key value of the key, and after channel searching is completed, a channel 1 is selected for playing. Meanwhile, the main tuner (tuner 1) locks the frequency point of the channel 1, and the controller analyzes the program information of the channel 1 for playing. When a user presses a channel list key on the control device, the display device calls a channel list in response to an instruction corresponding to the key value of the key.

And step two, when the user presses the direction key on the control device, the display equipment responds to the instruction corresponding to the key value of the key, and controls the focus to move from the channel 1 option to the channel 2 option. The controller changes the oscillation frequency of the tuner (tuner 2), locks the frequency point of the channel 2, analyzes the program image/video information of the channel 2 after the processing of the demodulator, the controller and the like, and displays the program image/video information in a small window at one side of a channel list; at the same time, the display keeps the broadcast of the channel 1 programming content.

And step three, when the user presses the confirm/OK key on the control device, the display equipment responds to the instruction corresponding to the key value of the key, selects to switch from the channel 1 to the channel 2, meanwhile, the small window is hidden, and the content displayed in the program content playing page of the display equipment is switched to the program content provided by the channel 2. At this time, tuner 2 becomes the master tuner and tuner 1 becomes the slave tuner. Here, channel 2 and channel 1 are not on the same frequency point.

And step four, when the user presses a direction key on the control device, the display equipment responds to an instruction corresponding to the key value of the key, controls the focus to move to other channel options, repeats the step two and the step three, and simultaneously alternately replaces the main tuner and the auxiliary tuner between the tuner 1 and the tuner 2. All channels under the double-frequency point can be simultaneously locked by utilizing the double-tuner, so that in the embodiment based on the double-tuner display equipment, all channels can be previewed without setting a preview mark.

The content display method of the embodiment of the application can comprise the following steps:

the method comprises the following steps: displaying program content provided by a first channel on a display; for example, as shown in fig. 2A, a program content playback screen 41 is displayed.

Step two: responding to a first input instruction, displaying a channel list on a display, wherein the channel list comprises a plurality of channel options; wherein the selector selects a first channel option of the plurality of channel options;

for example, when the user presses a channel list key on the control apparatus, the display device displays the channel list 41-1 in the program content playback page in response to an instruction corresponding to the key value of the key. The channel list contains a number of channel options: channel 1 option to channel 8 option. At this time, the focus is located on the channel 1 option providing the program content in the program content playing page, and the channel name of the channel 1 option being played is displayed at the same time in the upper left corner of the program content playing page.

Step three: and responding to a second input instruction, controlling the selector to move from the first channel option to a second channel option, and displaying the program content currently played by the second channel in a small window form while keeping displaying the program content provided by the first channel.

For example, when the user presses a direction key on the control apparatus, the display device controls the focus to move from channel 1 shown in fig. 2A to channel 2 shown in fig. 2B in response to an instruction corresponding to the key value of the key. Meanwhile, a small window 41-2 is displayed at one side of the channel list. The program content provided by channel 2 is displayed in the small window shown in fig. 2B.

Further, in response to a third input instruction, the small window is not displayed any more, and the program content provided by the first channel displayed on the display is switched to the program content provided by the second channel.

For example, in fig. 2B, when the user presses the confirmation key on the control apparatus, as shown in fig. 2C, the display device switches the program content provided by channel 1 displayed on the display to the program content provided by channel 2 in response to an instruction corresponding to the key value of the key, while the small window is no longer displayed.

With reference to fig. 3, a content display method according to an embodiment of the present application may include the following steps:

Step two: responding to a first input instruction, displaying a channel list on a display, wherein the channel list comprises a plurality of channel options; wherein the selector selects a first channel option of the plurality of channel options; and displaying preview marks for indicating that program content can be previewed at other channel options which are the same as the frequency point information of the first channel in the plurality of channel options.

For example, in fig. 2D, the content displayed on the current program content playing page is the program content provided by the channel 1 option, and the channel 2 and the channel 6 are at the same frequency point as the channel 1, and then the preview identifier (e.g., star shape as exemplarily shown in fig. 2D) is displayed on the channel 2 and the channel 6. And other channels which are not in the same frequency point with the channel 1 do not display the preview identification.

Step three: and responding to a second input instruction, controlling the selector to move from the first channel option to a second channel option with a preview mark, and displaying the program content currently played by the second channel in a small window form while maintaining the display of the program content provided by the first channel.

For example, in fig. 2D, when the user inputs an instruction to move the focus by pressing the direction key of the control device, the display apparatus controls the focus to move from the channel 1 option to the channel 2 option in response to the instruction. As shown in fig. 2E, since the channel 2 and the channel 1 are at the same frequency point and are simultaneously displayed with the preview identifier, a small window is displayed at one side of the channel list for displaying the program content provided by the channel 2 option.

Further, in response to a third input instruction, the small window is not displayed any more, and the program content provided by the first channel and displayed on the display is switched to the program content provided by the second channel; and updating and displaying the preview mark at other channel options which are the same as the frequency point information of the second channel in the plurality of channel options.

For example, as shown in fig. 2D, the content currently displayed on the display is the program content of channel 1. The channel option for displaying the preview identifier in the channel list is a channel with the same frequency point as that of the channel 1: channel 2 and channel 6. In fig. 2D, when the user presses the direction key on the control device, as shown in fig. 2F, the display apparatus controls the focus to move from channel 1 to channel 3 in response to an instruction corresponding to the key value of the key.

When the user presses the OK/OK key on the control device, the display device controls the display to switch the program content displayed from the content provided on channel 1 to the content provided on channel 3 in response to an instruction corresponding to the key value of the key, as shown in fig. 2G. The channel name shown in the upper left corner of the display is also changed to the name of channel 3. At the same time, the preview identification displayed on channel 2 and channel 6 options is dismissed. And the preview mark is displayed on the channel options of the channel 4 and the channel 8 which have the same frequency point with the channel 3.

With reference to fig. 4, a content display method according to an embodiment of the present application may include the following steps:

the method comprises the following steps: locking a frequency point of a first channel in the digital broadcast signal through a first tuner, and displaying program content provided by the first channel on a display; for example, when the user presses a channel search key on the control device, the display device responds to an instruction corresponding to the key value of the key, and after the channel search is completed, the display device selects channel 1 to play. Meanwhile, the main tuner (tuner 1) locks the frequency point of the channel 1, and the controller analyzes the program information of the channel 1 for playing.

Step two: responding to a first input instruction, displaying a channel list on a display, wherein the channel list comprises a plurality of channel options; wherein the selector selects a first channel option of the plurality of channel options; for example, when the user presses a channel list key on the control apparatus, the display device calls up a channel list in response to an instruction corresponding to the key value of the key, as shown in fig. 2A.
