Description

Display equipment and media data playing method

Technical Field

The application relates to the technical field of display equipment, in particular to display equipment and a media data playing method.

Background

The display device may provide audio and video data playback functions for the user. For example, the display device may search for a broadcast channel, and after the channel search is completed, the display device may play audio and video data corresponding to the broadcast channel. In order to enrich the play function of the display device, some operators create some network channels, and the media content broadcast by the network channels is different from the content broadcast by the broadcast channels, so that more choices are provided for users.

The broadcast channels and the network channels may be presented in a channel list by channel type, e.g., upon selection of a broadcast channel type, both broadcast channels are presented in the channel list. The probability of users cross-cutting between different types of channels is small. But in order to make it more convenient for the user to find the content that wants to watch, the broadcast channel and the network channel may be shown in the channel list by content type. For example, upon selection of a movie, the channel list shows more movie-related broadcast channels and/or network channels. The probability of users cross-cutting between different types of channels increases greatly.

When a user triggers a channel switching instruction and needs to switch to a network channel from a broadcast channel, a user interface can issue the channel switching instruction to an application management module, the application management module needs to pull up a browser, load the player through the browser, and then the player calls a media module to play network media resources, so that the whole link is more, the time is long, and the memory is occupied.

In some embodiments, the broadcast channels and the network channels may be presented in a channel list by channel type, e.g., upon selection of the broadcast channel type, both broadcast channels are presented in the channel list. The probability of users cross-cutting between different types of channels is small.

For example, after receiving an instruction of opening the live television software input by a user, playing media data corresponding to a default channel in response to the instruction. Upon receiving an instruction from the user to input a display channel list by pressing the confirm key of the control device 100, the display 260 is controlled to display a channel list interface in response to the instruction, as shown in fig. 5. The channel list interface includes a channel list presentation area 51 and a channel type presentation area 52. Channel type presentation area 52 includes DTV (Digital Television ) control 521, OTT (Over The Top) 1 control 522 and OTT2 control 523, which provide various application services to users Over The internet.

Current focus 53 indicates that broadcast channel 1 control 511 is selected. If an instruction of pressing a key input of the control device 100 by a user is received, a switch may be made from broadcast channel 1 to broadcast channel 2. If the instruction of pressing the right key and the down key of the control device 100 is received successively, the broadcast channel 1 can be switched to the default network channel corresponding to the OTT1 control 522.

It should be noted that the controls, which are visual objects displayed in the display areas of the user interface in the display device to represent corresponding contents such as icons, thumbnails, video clips, links, etc., may provide the user with various conventional program contents received through data broadcasting, and various application and service contents set by the content manufacturer.

The presentation form of the control is typically diversified. For example, the controls may include text content and/or images for displaying thumbnails related to the text content, or video clips related to the text. As another example, the control may be text and/or an icon of an application.

The focus is used to indicate that any of the controls has been selected. In one aspect, the control may be selected or controlled by controlling movement of a display focus object in a display device according to user input through the control apparatus 100. Such as: the user may select and control controls by directional keying movement of the control focus object between controls on the control device 100. On the other hand, the movement of each control displayed in the display device may be controlled to cause the focus object to select or control the control according to the input of the user through the control apparatus 100. Such as: the user can control the controls to move left and right together through the direction keys on the control device 100, so that the focus object can select and control the controls while the position of the focus object is kept unchanged.

The form of identification of the focal point is typically varied. For example, the location of the focus object may be achieved or identified by magnifying the control, and also by setting a background color of the control, or may be identified by changing a border line, size, color, transparency, outline, and/or font of the text or image of the focus control.

In some embodiments, broadcast channels and network channels may be presented in a channel list by content type. The broadcast channel and the network channel may merge into the same category. For example, upon selection of a movie, the channel list shows broadcast channels and/or network channels associated with the movie. The probability of users cutting each other among different types of channels is greatly increased, and higher requirements are put forward on the speed of starting network media resources.

For example, after receiving an instruction of opening the live television software input by a user, playing media data corresponding to a default channel in response to the instruction. Upon receiving an instruction from the user to input a display channel list by pressing the confirm key of the control device 100, the display 260 is controlled to display a channel list interface in response to the instruction, as shown in fig. 6. Channel list interface channel list presentation area 61 and channel type presentation area 62. Channel type presentation section 62 includes favorites control 621, favorites control 622, broadcast control 623, movie control 624, entertainment control 625, news control 626, and juvenile control 627. Channel list presentation area 61 includes broadcast channel 1 control 611, broadcast channel 2 control 612, broadcast channel 3 control 613, network channel 1 control 614, network channel 2 control 615, network channel 3 control 616, and focus 63 corresponding to movie control 624. Current focus 63 indicates that broadcast channel 3 control 613 is selected. If an instruction of pressing a key input of the control device 100 by a user is received, the broadcast channel 3 can be switched to the network channel 1.

In some embodiments, as shown in fig. 7, the step of switching from a broadcast channel to a network channel includes: after receiving an instruction of triggering the switching from the broadcast channel to the network channel by the user interface, the user interface sends a switching instruction to the application management module, and the application management module opens an application program corresponding to the network channel. The application program starts the network player. The network player calls the media module to play the media data corresponding to the network channel.

In some embodiments, as shown in fig. 8, the step of switching from a broadcast channel to a network channel includes: after receiving an instruction of triggering the switching from the broadcast channel to the network channel by the user interface, sending a switching instruction to the application management module, wherein the switching instruction comprises a network channel website. And the application management module pulls up the browser after receiving the platform cutting instruction. The browser loads the web player. The network player calls the media module to play the media data corresponding to the network channel.

When a user triggers a channel switching instruction and needs to switch from a broadcast channel to a network channel, the user interface can issue the channel switching instruction to the application management module, the application management module needs to pull up the browser, load the network player through the browser, and then the network player calls the media module to play the network media asset. According to the scheme, the step of opening the application program corresponding to the network channel is reduced, the playing link is shortened to a certain extent, and the playing speed of the network media asset is improved, but the probability of switching the broadcasting channel to the network channel is increased, and the playing speed of the network media asset is required to be higher. Relatively speaking, the whole link is still quite a lot, takes a long time (3-4 s), and occupies a large memory.

In order to solve the above technical problems, the embodiments of the present application provide a display device 200, and the structure and functions of each part of the display device 200 may be referred to the above embodiments. In addition, on the basis of the display device 200 shown in the above embodiment, the present embodiment further improves some functions of the display device 200. As shown in fig. 9, the controller 250 performs the steps of:

Step S901: receiving an instruction of switching to a first channel input by a user;

In some embodiments, the step of receiving a user input instruction to switch to a first channel, comprises:

An instruction input by a user to open a live application is received. After the live broadcast application program is opened, media data corresponding to a default channel or a channel when the live broadcast application program is quitted last time is played. The first channel is a default channel or a channel when the live application program is exited last time.

The live broadcast application program can integrate broadcast channels, namely, the conventional channels of LiveTV and television live broadcast services of network channels provided by operators, can provide network streaming media live broadcast services on the basis of the functions of the conventional LiveTV, and strengthen unique live broadcast watching experience of televisions.

In some embodiments, the media data corresponding to the second channel is played. A step of receiving a user input instruction to switch to a first channel, comprising:

receiving an instruction input by a user by pressing a direction key or a channel add/subtract key of the control device 100; or alternatively

After receiving an instruction for displaying a channel list input by a user, displaying the channel list on a window for playing media data, wherein the channel list comprises a first channel control, a second channel control and a focus, and the current focus indicates that the second channel control is selected;

An input instruction of a user by pressing a direction key of the control device 100 is received, so that a focus is moved from the second channel control to the first channel control.

Illustratively, as shown in fig. 6, broadcast channel 3 control 613 is a second channel control and network channel 1 control 614 is a first channel control. An instruction input by a user by pressing a key of the control device 100 is received to input an instruction to switch to the first channel.

Step S902: judging whether the first channel is a network channel or not;

Wherein the network channel is a channel provided by the media application. If the first channel is not a network channel, the first channel is a broadcast channel. The broadcast channel is a digital television (Digital Television, DTV) channel. Digital television is a television system that processes signals digitally from program acquisition, program production, program transmission to the user side, i.e. all links from studio to transmission, reception use digital signals, or are propagated by a digital sequence consisting of a 0, 1 digital string.

When the live broadcast application program is started or the live broadcast application program is started for the first time, the live broadcast application program can send a channel searching request, and channel data of broadcast channels in a full frequency band or a preset frequency band can be searched. The channel data includes a channel list, information bar data, EPG (ELECTRICAL PROGRAM GUIDE, electronic program guide) information, channel identification, channel information, and parental control identification. The channel list is used for displaying all channels or partial channels searched. The information bar data is used for displaying the content of the current channel and the program. The electronic program guide information is an electronic program menu for providing indexing and navigation of various services. The channel identification is used to identify the channel. The channel information includes a channel type and a media asset address. Channel types include source type and content type, etc. The source type includes a broadcast type and a network type. Content types include movies, entertainment, and children, among others. The channel source type and the content type are used to display channels having the same type in the same channel list. For example, channels whose content types are movies are displayed in the same list as shown in fig. 6. The media asset address is used to provide a way of acquiring media asset data. The parental control flag is used to identify whether the current channel is set to a locked state. The channel identification is stored corresponding to the channel information and the parental control identification. Channel data of broadcast channels are stored in a common storage area.

After the broadcast channel data transmits the update flag, the display apparatus 200 retransmits the channel search request after receiving the update flag to update the channel data of the broadcast channel. Or periodically transmitting a channel search request to periodically update channel data of the broadcast channel.

When a live broadcast application program is started or started for the first time, the live broadcast application program can send a network channel request to a server;

And receiving channel data of the network channel issued by the server based on the network channel request, wherein the channel data comprises a channel list, information bar data, EPG (ELECTRICAL PROGRAM GUIDE, electronic program guide) information, a channel identifier, channel information and a parental control identifier. The channel data also provides a media data playing method, a tool method and the like. Channel data for network channels is stored in a common storage area.

After the network channel data transmits the update identification, the display device 200 receives the update identification transmitted by the server. The display apparatus 200 may again request a network channel to the server so that the server again transmits channel data of the network channel. Or periodically send a network channel request to periodically update the channel data of the network channel.

In some embodiments, the technical architecture diagram is shown in FIG. 10. The application layer includes a user interface layer. The user interface layer comprises a live application module, a network channel module, a Setting module, a desktop starter module and a Voice module. The live application module stores channel data of the broadcast channel in a common storage area. The network channel module acquires channel data of the network channel from the server, stores the channel data in the database, and provides a playing method and a tool method for the live broadcast application module, so that the live broadcast application module can call the network channel module after receiving an instruction of playing the network channel input by a user, and media data playing of the network channel is realized. The network channel module stores channel data of the network channels in a common storage area. An SDK (Software Development Kit ) is a collection of development tools in building application software for a particular software package, software framework, hardware platform, operating system, etc. User interface displays and the like are dependent upon software development kits. The browser (Cobalt) is a lightweight HTML5/CSS/JS application container that aims to provide a rich application development environment with minimal resource consumption (deployment size, RAM, CPU, GPU). The Cobalt browser carries the entire user interface on top and serves as a base bridge for the communication of the user interface with the television system (middleware) on the bottom. The middleware layer includes an application management module (Application Manager, APM), a local Media player (Domestic MEDIA PLAYER, DMP), a network player, and a Media module (Media).

Before judging whether the first channel is a network channel, judging whether a channel before switching exists;

if the pre-switch channel does not exist, whether the first channel is a network channel is directly judged.

It should be noted that, there is no channel before switching to indicate that the current scene is not switched from one channel to another, but the user directly opens the live broadcast application program through the key or voice command of the control device to directly play the media data of the first channel.

If the channel before switching exists, judging whether the channel before switching is a broadcast channel or not;

The step of judging whether the channel before switching is a broadcast channel includes:

Determining a channel identifier corresponding to a channel before switching;

acquiring the channel type corresponding to the channel identifier from a public storage area;

The channel type includes a channel source type identification. Illustratively, a channel source type of 0 indicates that the first channel is a broadcast channel; a channel source type of 1 indicates that the first channel is a network channel.

Judging whether the channel before switching is a broadcast channel, namely judging whether the channel source type identifier is 0;

if the channel source type is marked as 0, determining that the channel before switching is a broadcast channel;

If the channel source type identification is not 0 but 1, the pre-switch channel is determined to be a network channel.

If the pre-switch channel is a broadcast channel, a step of judging whether the first channel is a network channel is performed.

If the pre-switch channel is not a broadcast channel, the step of judging whether the first channel is a network channel is not performed, but the channel information of the first channel is transmitted to an application management service, and the application management service transmits the channel information to a corresponding player.

The step of judging whether the first channel is a network channel or not includes:

Determining a channel identifier corresponding to the first channel;

Obtaining channel information corresponding to the channel identifier from a public storage area, wherein the channel information comprises a channel type and a media resource address;

judging whether the first channel is a network channel or not, namely judging whether the channel source type identifier is 1 or not;

If the channel source type is identified as 1, determining that the first channel is a network channel;

if the channel source type identification is not 1 but 0, the first channel is determined to be a broadcast channel.

If the first channel is a network channel, step S903 is performed: transmitting channel information of a first channel to a local media player;

The local media player is used to play audio and video data stored in the display device 200 or audio and video data stored in an external storage device of the display device 200. The local media player may also support network media asset playback. The local media player is a player local to the display device and is integrated into the operating system of the display device 200. The local media player may also operate without networking, i.e., may play audio and video data stored in the display device 200 or an external storage device of the display device 200 without networking.

It should be noted that the local media player is not the same as the network player, and the local media player and the network player are different players designed according to two different application scenarios. The network player is essentially a web page, loaded by Odin browser, deployed in its own server, and can be used only after networking.

The channel information includes channel type, media address, channel name, carrier name, etc.

In some embodiments, the step of transmitting channel information for the first channel to the local media player comprises:

And after receiving an instruction of switching to the first channel input by the user, the live broadcast application module acquires the channel type of the first channel from the public storage area. And after determining that the channel type of the first channel is a network channel, invoking a network channel module to enable the network channel module to send the channel information of the first channel to an application management module.

In some embodiments, the ability of the local media player to play network media assets is determined by setting a play identifier. A step of transmitting channel information of a first channel to a local media player, comprising:

Acquiring a playing identifier of a local media player;

judging whether the play identifier is a preset value, for example, the preset value is set to be 1;

If the play identifier is not a preset value, for example, the play identifier is 0, the channel information of the first channel is not sent to the local media player, and the play identifier does not represent that the display device does not support playing of media data corresponding to the network channel through the local media player for the preset value.

In some embodiments, if the play identifier is not a preset value, the browser may be pulled up, and the web player is loaded through the browser. The network player calls the media module to play the media data corresponding to the first channel.

And after receiving an instruction of switching to the first channel input by the user, the live broadcast application module acquires the channel type of the first channel from the public storage area. And after determining that the channel type of the first channel is the network channel, invoking a network channel module. And whether the display equipment supports playing the media data corresponding to the network channel through the local media player or not determines the data structure transmitted to the application management module by the network channel module.

The network channel module judges whether the playing identifier is a preset value or not; if the playing mark is a preset value, the channel information of the first channel is sent to the application management module in a first data structure. Illustratively, the first data structure comprises an original structure, i.e., a non-encapsulated data structure. The media resource address is in M3U8 format, and is directly sent to the application management program. Wherein, M3U8 is a streaming media file format based on HTTP, mainly used for describing URL addresses of multiple pieces of audio and video data. It is used to transmit and play audiovisual content over a network. Unlike traditional post download playback, the M3U8 file may be played directly on a browser or mobile device. If the play identifier is not the preset value, the channel information of the first channel is sent to the application management module in a second data structure. Illustratively, the second data structure comprises a packaged data structure. And the channel information is packaged and then sent to an application management module.

judging whether the channel type of the channel corresponding to the current media data is the same as the channel type of the first channel;

If the channel type of the channel corresponding to the current media asset data is different from the channel type of the first channel, suspending playing of the current media asset data, and judging whether the channel information is in the first data structure after suspending playing.

It should be noted that the first channel is a network channel. The channel type of the channel corresponding to the current media asset data is different from the channel type of the first channel, so that the current media asset data is a broadcasting channel. The application management module may send a stop play command to the signal source service. The signal source service is used for playing media data corresponding to the broadcast channel. And after receiving the signal source resource release notification fed back by the signal source service, judging the channel information as a first data structure.

If the channel information is judged to be in the first data structure, the channel information of the first channel is transmitted to the local media player.

And if the channel type of the channel corresponding to the current media data is the same as the channel type of the first channel, sending channel information according to the playing path of the current media data. It should be noted that the first channel is a network channel. The channel type of the channel corresponding to the current media asset data is the same as the channel type of the first channel, and the current media asset data is a network channel. For example, if the current media asset data is played through the local media player, channel information for the first channel is transmitted to the local media player. And if the current media asset data is played through the network player, transmitting the channel information of the first channel to the network player.

In some embodiments, the application management module determines whether the first channel is set to the locked state after receiving the channel information of the first channel;

In some embodiments, the step of determining whether the first channel is set to a locked state comprises:

Acquiring a media resource address;

Judging whether the first channel is set to be in a locking state according to the media resource address;

the lock state is that parents set a parental lock on a channel to prevent children from viewing the content of the channel unsuitable for the age group. The user needs to input the correct password before watching.

Judging whether the first channel is set to be in a locking state according to the media resource address, wherein the step comprises the following steps:

judging whether the media resource address comprises a locking field or not;

if the media resource address comprises a locking field, determining that the first channel is set to be in a locking state;

and if the media resource address does not comprise a locking field, determining that the first channel is not set to be in a locking state.

In some embodiments, if the first channel is a network channel, the channel information of the first channel is transmitted to the application management module along with the parental control identification. The step of judging whether the first channel is set to a locked state includes:

Judging whether the parental control identifier is a preset value, for example, the preset value is 1;

If the parental control identifier is a preset value, determining that the first channel is set to be in a locking state;

If the parental control identification is not a preset value, e.g., the parental control identification is 0, it is determined that the first channel is not set to a locked state.

And if the first channel is set to be in a locking state, transmitting the silence parameters and the media information to a local media player. The silence parameter is used for indicating silence playing media resource data, the media resource data comprises video data and audio data, and the silence playing media resource data comprises that video data is replaced by a black screen picture to be played and audio data is not played.

The network channel has no own user interface, and the information bar, the channel list, the EPG and other LiveTV user interfaces are integrated into the user interface of the live broadcast application program from the aspect of product design. Information such as information bars of the network channels can be displayed through a user interface of the live broadcast application program. The network channel media asset is streaming media, the media module can be called to play through the way of the local media player, and the current network channel has no DRM (DIGITAL RIGHTS MANAGEMENT ), namely encryption, so that the media playing and decryption capability of the browser can be eliminated.

And calling the media module after the local media module receives the silence parameters. And the media module silently plays the media data corresponding to the first channel based on the media address and the silencing parameter, and controls the display to display the password input interface. The silent playing of the media data corresponding to the first channel is to replace the video data playing of the first channel with a black screen picture, and not to play the audio data of the first channel.

After receiving the message of the correct password input by the user in the password input interface, sending the message of canceling the silent playing to the local media player so that the local media player controls the media module to cancel the silent playing and normally plays the audio data and the video data corresponding to the first channel.

In some embodiments, after playing the media video of the first channel, the user input may be received again to switch to the first channel. For example: after playing the media video of the first channel, receiving an instruction of switching to the first channel through voice instruction input by a user. After receiving the instruction, channel information of the first channel is sent to the local media player. After the local media player pauses playing the media asset data corresponding to the first channel, controlling the media module to play the media asset data corresponding to the first channel again based on the channel information. The scheme can generate a picture clamping effect from pause to replay.

In some embodiments, after receiving the user input instruction to switch to the first channel again, the channel information of the first channel is sent to the local media player; the local media player judges whether the channel information before and after switching is changed; if the channel information before and after switching is unchanged, the media module is controlled to continuously play the media resource data corresponding to the first channel, the current media resource is not required to be paused, the media module is not required to be called, and any related operation for switching the channel can not be executed. And if the channel information before and after the switching is changed, after the current media asset data is paused to be played, controlling the media module to play the media asset data corresponding to the channel after the switching based on the channel information.

In some embodiments, the public storage area further stores media parameters corresponding to the channel identifiers. The media asset parameter is an inserted media asset address corresponding to the inserted media asset data. The inserted media data can be advertisement, media film or brief introduction, etc. The insertion location may be within a predetermined period of time before, after, or during the playing of the first channel media data. The network channel module sends the channel information and the media parameters to the application management module. The application management module transmits the channel information and the media asset parameters to the local media player. The local media player calls the media module to play the media data corresponding to the first channel and plays the media data corresponding to the media parameters at the preset insertion position. For example, the media asset data corresponding to the media asset parameter may be played first, and after the media asset data is played, the media asset data corresponding to the first channel is played.

In some embodiments, as shown in fig. 11. After receiving the instruction of switching the broadcasting channel to the network channel, the user interface sends the channel information of the network channel to the application management module. Wherein the channel information includes a media asset address. After receiving the channel information, the application management module pauses playing of media data of the broadcast channel, sends a request for pulling up the player to the local media player, and sends a successful notification of switching the local media player to the application management module after the local media player is pulled up. It should be noted that only after power-on, the local media player needs to be pulled up for the first time. After receiving the successful notification of switching the local media player, the application management module starts the media play control service (MpCtrl-biz (player media)) and sends channel information to the media play control service. After the media resource playing control business is ready, channel information is sent to the media module, so that the media module automatically plays media resource data corresponding to the media resource address. And the media module sends the playing result to the media resource playing control service. And the media asset playing control service sends the playing result to the application management module. And the application management module sends the playing result to the user interface, namely, throws up the zone bit of the network channel being played. This information may be used to store in a log.

In some embodiments, as shown in fig. 12, the user interface sends channel information of a network channel to the application management module after receiving an instruction from a user to switch from a broadcast channel to the network channel. The application management module transmits the channel information to a source-bil service (source-bil). The source service transmits channel information to the television service (tvservice-biz). The television service traffic sends channel information to the bottom layer (chassis). The bottom layer switches channels based on the channel information and sends a successful switching message to the signal source service. The signal source service sends a switching success message to the application management module. The application management module sends the ready-to-play instruction to the media resource play control service and sends a start loading message to the user interface.
