In some embodiments, the live television application may provide live television, broadcast television, through different signal sources. For example, a live television application may provide television signals using inputs from cable television, radio broadcast, satellite services, or other types of live television services. And, the live television application may display media data of the live television signal on the display device 200.

In some embodiments, the video on demand application may provide video from different storage sources. Unlike live television applications, video-on-demand provides media asset data from some storage sources. For example, video-on-demand may come from a server side of cloud storage or from a local hard disk storage containing stored video programs, etc.

In some embodiments, the media center application may provide various multimedia content playing applications. For example, a media center may be a different service than live television or video on demand, and a user may access various images or audio through a media center application.

In some embodiments, an application center may be provided to store various applications. The application may be a game, an application, or some other application associated with a computer system or other device but which may be run in a smart television. The application center may obtain these applications from different sources, store them in local storage, and then run on display device 200.

The display device 200 may play a variety of programs based on the above-described applications, such as a live television application or a video on demand application, etc. In some embodiments, different programs may correspond to different media asset types, and the programs of different media asset types may transmit media asset data based on different transmission modes. For example, the resource types may include network assets and non-network assets, the network assets including Internet protocol information. The internet protocol information includes URL (Uniform Resource Locator ) addresses of programs. The display device 200 can acquire the media asset data of the program by accessing the URL address.

In order for display device 200 to obtain corresponding media data based on an application, as shown in fig. 6, in some embodiments, display device 200 may communicate with server 400 to implement data interactions. For example, the display apparatus 200 may transmit a request for acquisition of media asset data to the server 400 in response to an interactive instruction input by the user. The display device 200 controls the display 260 to display the corresponding media data according to the media data fed back by the server 400.

To facilitate data interaction between the display device 200 and the server 400, in some embodiments, the display device 200 needs to establish a communication connection with the server 400, and then interact with the server 400 through the established communication connection relationship. For example, the display device 200 and the server 400 may establish a communication connection through transmission networks of different transmission protocols, and transfer interactive data between the display device 200 and the server 400 through the transmission networks.

In some embodiments, it may be necessary to provide components for establishing a communication connection on the display device 200 and the server 400, respectively. That is, as shown in fig. 5, a communicator 220 may be provided in the display device 200, and a communication module may be provided in the server 400, and the communicator 220 and the communication module may simultaneously support at least one identical communication manner to establish a communication connection relationship. For example, the communicator 220 on the display device 200 includes a fiber optic interface, such that the display device 200 may connect to a network through the fiber optic interface; meanwhile, the communication module of the server 400 also includes an optical fiber interface, and the network may also be connected through the optical fiber interface, so as to implement communication connection between the display device 200 and the server 400.

It should be noted that, the display device 200 and the server 400 may also use other connection methods to establish a communication connection relationship. Such as wired broadband, wireless local area network, cellular network, bluetooth, infrared, radio frequency communications, etc.

A "many-to-one" connection may be between the display device 200 and the server 400, i.e., multiple display devices 200 may establish a communication connection with the same server 400, such that the server 400 may provide services to multiple display devices 200. The display device 200 and the server 400 may also be in a "many-to-many" connection relationship, i.e., the plurality of display devices 200 may establish communication with the plurality of servers 400, so that the plurality of servers 400 may respectively provide different services for the display device 200. It is obvious that in an individual application scenario, there may also be a "one-to-one" connection between the display device 200 and the server 400, i.e. one server 400 is dedicated to serve one display device 200.

In order to be able to provide services to the display device 200, a storage module may be further included in the server 400, and the storage module may store various resource data, information files, and control programs. In response to the user's interaction, the display device 200 may acquire different data in the storage module of the server 400, for example, the display device 200 may send a play data acquisition request to the server 400 when a certain media item is requested, and after receiving the request, the server 400 may extract the media data to be played in the storage module and transmit the media data to the display device 200, so that the display device 200 may decode and display the media data. The control program stored in the storage module may be executed by the control module of the server 400, so that the control module may perform a corresponding function according to the control program.

Based on the display device 200 and the server 400, when transmitting data, the display device 200 may establish a communication connection with the server 400 based on different protocols to realize the transmission of media data.

Thus, in some embodiments, the network asset may be a program of the DVB-I (digital video broadcasting-InternetPr otocol) protocol. The DVB-I protocol is a protocol specified by the digital video broadcasting International organization, and is a television protocol based on an IP network. That is, the DVB-I protocol is an IP network protocol proposed based on DVB (DigitalVideoBroadca sting, DVB). Among them, DVB is a series of internationally recognized digital television public standards maintained by the digital video broadcasting organization, including digital terrestrial broadcasting system standard (DVB-T), digital cable broadcasting system standard (DVB-C), digital satellite living broadcast system standard (DVB-S), and the like. The display device 200 may transmit media asset data of the program based on the IP network according to the URL address in the DVB-I protocol program.

When the media asset type is not network media asset, the display device 200 may receive the broadcast signal of the program to obtain the media asset data corresponding to the program. In some embodiments, the display device 200 includes a tuning module (Tuner), a demodulation module (Demod), a demultiplexing module (Demux), and a decoding module (Demux). While viewing programs of non-network media, the display apparatus 200 tunes a broadcast signal of the display apparatus 200 through a tuning module and demodulates the signal through a demodulation module. Meanwhile, by combining the above two modules with the demultiplexing module and the decoding module, the display device 200 can receive the broadcast signal of the program, and perform operations such as decoding, so as to play the corresponding program through the display device 200.

To facilitate the user's selection of a corresponding program to play in display device 200, in some embodiments, display device 200 may also generate a program listing from media items contained in display device 200 and display the program listing in display 260, providing a program navigation mechanism for display device 200. For example, the program listings may be an electronic program guide (ElectronicPr ogramGuide, EPG) page, a media recommendation page of a top page interface, or a channel listing as shown in fig. 7, etc.

In some embodiments, the display apparatus 200 may acquire a plurality of control instructions input by a user, wherein a portion of the control instructions are control instructions for controlling the display apparatus 200 to present a program list, which is referred to as a presentation instruction of the program list. The user may enter program listings query instructions via different interaction means or based on different user interfaces. The display device 200 then controls the display 260 to display the program list in response to the presentation instruction. The program list comprises tabs of programs, and one tab corresponds to one media item. The user can generate a playing instruction of the program by executing a selection operation on the tab. The display device 200 plays the program corresponding to the tab in response to the play instruction.

Since part of the program is only played at a fixed time point, the program cannot be watched when the time point of playing the program is missed. Accordingly, to meet the viewing needs of the user, in some embodiments, the display device 200 may further record the program, and buffer the media data of the program into the display device 200 for the user to play back and view the program. The media data is cached by storing the media data in the memory 280 of the display device 200, and the memory 280 may be a local disk or other memory hardware.

The display device 200 starts a recording process of the program according to a recording instruction for recording the program. Wherein the recording instructions may be entered based on a program listing of the display device 200. Thus, in some embodiments, the display device 200 receives a presentation instruction for displaying a program listing and, in response to the presentation instruction, controls the display 260 to display the program listing. The program list comprises a tab of a program, wherein the tab comprises a recording control, and the recording control is the program control for triggering a recording instruction. The user can generate a recording instruction corresponding to the program by selecting the recording control. Therefore, when the recording control is in the selected state, a recording instruction is generated.

For example, at a time of 19:00, the user inputs a presentation instruction of the channel list to the display apparatus 200 through a remote controller that is matched with the display apparatus 200. The display device 200 then controls the display 260 to display the channel list as shown in fig. 7 in response to the display instruction of the channel list. The channel list comprises program tabs of each channel at 19:00, and the tabs comprise recording controls of the program. The user may generate a recording instruction corresponding to the program by performing a selection operation on the recording control, so that the display device 200 may perform a corresponding recording program according to the recording instruction.

It should be noted that, the channel list provided in the embodiments of the present application is only an exemplary illustration of a program list. The programs of the application can also be other forms of lists, such as a top page list of each application program, a media resource recommendation list and the like. The present application is not limited in this regard.

To facilitate recording of the program by the user, in some embodiments, display device 200 also controls display 260 to display a recording setup interface in response to a selected operation of a recording control prior to generating the recording instructions. The recording setting interface comprises a program option control and a recording duration control, wherein the recording duration control comprises a sub control of recording start time and recording end time. The program option control is all program options located after the current time point in the channel, and the user can record the complete video under the program option by selecting the program option control. After the user selects the recording duration control, the display device 200 displays sub-controls of the recording start time and the recording end time, and the user can customize the recording duration of the program through the two sub-controls.

For example, as shown in fig. 7, after the user selects the recording control of the channel DCd in fig. 7, the display device 200 displays the recording setting interface of the DCd. In fig. 7, the time is 19:00, and the recording setup interface presents the program option control of the DCd after 19:00, including the program 4 option control currently being played. At this time, the user may directly click on the option control of the program 4 to generate a recording instruction of the program 4. The display device 200 can automatically complete recording of the program 4 according to the playing time of the program 4.

In some embodiments, when the display apparatus 200 records a program, tuning is performed on a broadcast signal of the program by a tuning module built into the display apparatus 200 so that the display apparatus 200 can receive the broadcast signal of the program. Decoding is performed on the broadcast signal to form a media data stream of the target program. The media data stream is then written to the memory 260 of the display device. When the user wants to review the program, the program can be reviewed through the data stored in memory 260.

However, since one tuning module can support signal tuning of only one broadcast program at a time. Therefore, if a user wants to record a plurality of broadcast programs at the same time, a plurality of tuning module implementations are required. For example, the user wants to record channels DC a and DCb at 19:00-19: a program played in 45 time slots requires two tuning modules to tune the signal. Thus, if the number of broadcast programs recorded by the user is greater than the number of tuning modules of the display apparatus 200, the display apparatus 200 cannot complete the recording of the multi-channel broadcast program. For example, when one tuning module is built in the display device 200, the user cannot record two programs in the same time period, which results in a decrease in the recording efficiency of the programs in the display device 200 and a decrease in the experience of the user.

Based on the above application scenario, in order to improve the problem of low recording efficiency of the program in the display device 200, some embodiments of the present application provide a display device 200, as shown in fig. 8, including a display 260, a memory 280 and a controller 250. The display 260 is configured to display a user interface, the memory 280 is configured to store media data, and the memory 280 may be a magnetic disk or storage hardware built into the display device 200 or an external storage device. As shown in fig. 9, the controller 250 is configured to perform the following program steps:

s100: and responding to the recording instruction of the target program, and detecting the media asset type of the target program.

After receiving the recording instruction for the target program, the display apparatus 200 detects the media asset type of the target program in response to the recording instruction. The media asset type comprises network media assets and non-network media assets, the network media assets comprise Internet protocol information, and the Internet protocol information comprises resource locator addresses of programs. Since the media asset types of the programs in the display device 200 may be plural, the media asset type of the target program is detected before recording the target program, so as to determine the media asset data acquisition mode corresponding to the target program.

Accordingly, as shown in fig. 10, in some embodiments, when the display apparatus 200 detects the media asset type of the target program, program information of the target program is detected. The program information includes media data transmission protocol including Internet protocol and broadcast network protocol. For example, the internetworking protocol may be the transmission protocol of DVB-I and the broadcast network protocol may be the transmission protocol of DVB. Since the internet protocol is based on IP network transmission, the corresponding internet protocol information includes the resource locator of the program. Thus, if the transport protocol is an internetworking protocol, the marked asset type is network asset. Otherwise, if the transmission protocol is a broadcast network protocol, the marked media asset type is non-network media asset.

For example, the display apparatus 200 acquires program information of a target program when detecting the type of the media asset of the target program, and detects the data content contained in the program information to determine the transmission protocol of the media asset data. If the channel information includes the IP address and URL address of the target program, the marked media asset type is network media asset. If the channel information does not include the IP address and the URL address of the target program, the marked media asset type is non-network media asset.

In some embodiments, when the display device 200 detects the media asset type of the target program, the target media asset type of the target program may also be determined according to the channel information corresponding to the target program. That is, when the display apparatus 200 detects the media asset type of the target program, channel information corresponding to the target program is queried. If the channel information includes an Internet application service, the type of the marked media asset is a network media asset. For example, taking the DVB-I channel as an example, the channel corresponding to the DVB-I program includes internet application services such as video on demand, application stores, social media, and the like.

S200: if the media asset type is network media asset, downloading media asset data of the target program according to the resource locator address, and writing the media asset data into the memory.

After detecting the media asset type of the target program, the display device 200 may acquire media asset data of the target program according to the transmission mode of the media asset type, so as to record the target program. If the media asset type is network media asset, the media asset data of the target program can be directly downloaded according to the resource locator address of the target program. At this time, since the media data is downloaded based on the network, the display device 200 does not need the tuning module to tune the signal, so as to record multiple programs simultaneously. After downloading the asset data, the display device 200 writes the asset data to the local memory 280. Thus, the user can review the target program through the media data stored in the memory 280.

In some embodiments, the process of the display device 200 downloading the media asset data according to the resource locator is implemented based on the browser of the display device 200. That is, when the asset type is a network asset, the display apparatus 200 may create a browser process for downloading the asset data, and access a web page address corresponding to the resource locator through the browser process to download the asset data of the target program.

S300: if the media asset type is non-network media asset, inquiring a target network media asset corresponding to the target program; and when the target program has the target network media resource, downloading the media resource data of the target program according to the resource locator address, and writing the media resource data into the memory.

In some embodiments, when the display device 200 downloads the media asset data of the target program according to the resource locator address, the web page address corresponding to the resource locator is accessed, the resource data of the web page address is acquired, and the resource data is loaded. Wherein the resource data includes media asset data of the target program. That is, the display device 200 may load the resource data of the target program by accessing the corresponding web page address, thereby implementing the cache download of the media resource data.

According to the above embodiment, since the network resource does not need the tuner to perform signal demodulation, the recording process of the non-network resource and the network resource can be performed simultaneously, so as to record multiple programs.

When the display apparatus 200 detects that the media asset type of the target program is a non-network media asset, it indicates that the current program is a conventional broadcast program. At this time, the display apparatus 200 inquires in the database whether there is a target network media corresponding to the target program. For example, the target program is a DVB program, and the display device 200 queries whether DVB-I program information corresponding to the DVB program exists in the database, and obtains the target network media asset according to the queried DVB-I program information.

Therefore, when the display device 200 queries that the target program has the target network asset, the asset data is downloaded according to the resource locator corresponding to the target network asset, and the downloaded asset data is written into the memory 280 local to the display device 200. At this time, the display device 200 still records the target program in a network downloading manner, so that the number of tuning modules during recording the program can be improved, and further the program recording efficiency of the display device 200 is improved.

After the display device 200 queries the target network media corresponding to the target program, if the target network media is not stored, the program is recorded by the broadcasting signal of the target program. That is, in some embodiments, when the target program does not exist in the target network medium, the display device 200 is switched to the signal source corresponding to the target program. And receiving the broadcast signal of the target program provided by the signal source, and decoding the broadcast signal to form a media data stream of the target program. After the display device 200 acquires the media asset data stream of the target program, the media asset data stream is copied, and the copied media asset data stream is written into the memory 280.

As shown in fig. 11, in some embodiments, the display device 200 further includes a tuner 211. The tuner 211 may be a sub-module integrated into the tuner demodulator 210, or may be a separate tuning module, where the tuner 211 is configured to tune a frequency point of the display device 200. When the display apparatus 200 is switched to the signal source of the target program, the display apparatus 200 also acquires the channel information of the target program. The channel information comprises a target frequency point of a target program. After the display apparatus 200 acquires the channel information, the target frequency point of the target program is parsed in the channel information, and the signal source is adjusted to the target frequency point through the tuner 211.

Since one tuner 211 can support signal tuning of only one program at a time, in some embodiments, as shown in fig. 12, the display apparatus 200 also detects the use state of the tuner 211 and acquires the number of coordinators in the idle state before switching to the signal source of the target program. The using states comprise a working state and an idle state. If the number of coordinators in the idle state is equal to 0, it is indicated that there is no broadcasting signal in which the idle coordinator 211 can tune the target program in the current display device 200. At this time, the display device 200 controls the display 260 to display the prompt information of recording failure. If the number of the coordinators in the idle state is greater than or equal to 1, which means that there is a broadcasting signal in which the idle coordinator 211 of the current display device 200 can tune a target program, the display device 200 adjusts a signal source to a target frequency point through the tuner 211 in the idle state.

For example, one tuner 211 is built in the display apparatus 200, and the tuner 211 is performing recording of program 1 in the DCa channel. At this time, the user transmits a recording instruction for program 2 in DCb to the display apparatus 200 through the remote controller device associated with the display apparatus 200. After receiving the recording instruction, the display device 200 traverses the use state of the tuner 211 in response to the recording instruction. Since only one coordinator 211 exists in the display device 200, the coordinator 211 is in an operating state. Therefore, the number of the coordinators in the idle state acquired by the display device 200 is 0, and the display device 200 controls the display 260 to display a prompt window of recording failure, in which a prompt word of "recording the program 1 and recording the program 2 fails" is displayed.

Based on the above embodiment, the display device 200 may obtain the media data through the tuner 211 and the network downloading mode at the same time, and write the media data into the memory 280 to record the program. Because the network download does not rely on the tuner 211 to perform signal tuning, the user records programs with the types of media assets being network media assets and non-network media assets respectively, thereby realizing the recording of multiple programs.

For example, taking DVB programs and DVB-I programs as examples, the program type of DVB programs is non-network media and the program type of DVB-I programs is network media. The user wants to record program 1 and program 3 simultaneously in display device 200. Wherein program 1 is a DVB program and program 3 is a DVB-I program. The user may first input a recording instruction of program 1 to the display apparatus 200, and the display apparatus 200 queries the database for the presence of DVB-I program information for program 1 in response to the recording instruction of program 1. After querying that no DVB-I program information is present in the database, the display apparatus 200 tunes the signal source to the frequency point of program 1 through the tuner 211 to perform recording of program 1. At this time, the user inputs a recording instruction of the program 3 to the display device 200, and the display device 200 downloads the media data of the program 3 according to the URL address of the DVB-I program information corresponding to the program 3, so that the display device 200 performs recording of the program 1 and the program 3 at the same time.

To facilitate recording of multiple programs, in some embodiments, the program listings include a check pattern that can perform a check operation on a recording control for multiple programs. The user can adjust the program list to a check mode by the control apparatus 100 and simultaneously input recording instructions of a plurality of programs in the check mode.

In some embodiments, the memory 280 may also be an external memory connected to the display device 200, and the display device 200 may write the media data into the external memory through the connection relationship with the external memory. Since the program can only be played in the authorized device, the media data needs to be encrypted and protected when recording.

Thus, in order to protect the asset data of the program, the asset data may only be played in the authorized device, and in some embodiments, the display device 200 may also encrypt the asset data when recording the program, such that the asset data may only be played in the authorized display device 200.

As shown in fig. 13, in some embodiments, the display device 200 also detects a characteristic value of the display device 200 when the asset data is written to the memory 280. Wherein the characteristic value comprises identification information, such as a mac address, SN number, etc., for characterizing the display device 200. After detecting the feature value of the display apparatus 200, the display apparatus 200 sets a key according to the feature value, and encrypts the media asset data based on an encryption algorithm to form encrypted video data of the target program. The encrypted video data is written into the memory 280 to protect the media data of the target program.

The encryption algorithm is to execute encryption processing on the clear text media asset data to make the media asset data become a section of unreadable code to form encrypted video data. The encrypted video data can only display original plaintext data after the corresponding key is input, that is, the encrypted video data can only be decrypted through the characteristic value of the display device 200, and the encrypted encoded information is converted into the original form of the media asset data.

Accordingly, the display apparatus 200 can decrypt the asset data by the feature value. That is, in some embodiments, the display apparatus 200 also extracts the asset data in the memory 280 in response to a playback instruction for the target program, and performs decryption of the asset data by the feature value, and controls the display 260 to display a play screen of the asset data. In this way, the media data of the memory 280 can only be played in the authorized display device 200, so as to protect the media data of the program and improve the security of the media data.

In some embodiments, a playback list is configured in display device 200 for presenting playback option controls for recorded programs. That is, the display device 200 may generate a playback list of the program based on the media data stored in the memory 280. The user may generate the playback instruction by performing a selected operation on a playback option control.

Based on the display device 200, some embodiments of the present application further provide a recording method of multi-media assets, as shown in fig. 9, the method includes the following program steps:

s100: detecting a media asset type of a target program in response to a recording instruction of the target program, wherein the media asset type comprises network media assets and non-network media assets, the network media assets comprise internet protocol information, and the internet protocol information comprises a resource locator address of the program;

s200: if the media asset type is network media asset, downloading media asset data of the target program according to the resource locator address, and writing the media asset data into a memory;
