The multimedia device corresponds to, for example, a network TV, a smart TV, a hybrid broadcast broadband television (HBBTV), an internet TV, a web TV, an IPTV (Internet Protocol Television), and the like.

TV (TeleVision) using existing terrestrial or cable is developing into a smart TV capable of interactive service based on the web. The development of smart TVs allows the installation and use of a number of applications produced and supplied by professional developers in addition to content produced or acquired by broadcasters. In addition, as the utilization of smart phones increases, the applications of the smart phones and smart TVs are diversified, and accordingly, various additional services are provided.

Accordingly, modern TVs can mount various types of applications using middleware. However, since the application has a dependency on a specific operating system (OS) or middleware, it is not possible to load the application onto the TV depending on the operating system and what middleware the TV is made of. It is decided.

Of course, if you have certain requirements, such as a flash engine or a Java execution environment, you can use flash or Java to reduce your dependency on the operating system.

However, even in this case, in order to control the hardware platform of the actual TV, a function must be called to match an API (Application Programming Interface) provided by the hardware platform. Therefore, even in the case of supporting the same Java application, in order to mount the application on a TV having a different hardware platform, there is a hassle of redevelopment to meet the API of the platform.

That is, in order to load an application developed on one platform on another platform, significant modifications are required.

Also, another embodiment of the present invention is to define a matching table of an application API and a platform control API to control an application independently of a platform.

In addition, another embodiment of the present invention is to provide an environment in which an application can be executed independently of the platform so that the application can be utilized in various platforms.

According to an embodiment of the present invention, a multimedia device for driving an application independently of a platform may include a first memory for storing a matching table and an application programming interface (API) of the application using the first memory. A matching unit for matching with a control API, a driving unit for loading the application into a second memory, executing the application, and calling the control API of the platform according to the matching result when executing the application. It includes a controller to control.

In addition, the method of controlling a multimedia device for driving an application independently of a platform according to an embodiment of the present invention may include loading the application into a memory and storing data for generating the matching table with an external server. Receiving, generating a matching table using the data, storing a matching table of the application in the memory, receiving a request to execute the application, and using the matching table. Matching an application programming interface (API) of the application to a control API of the platform; and calling the control API of the matched platform to execute the application.

As used herein, terms used in the present invention are selected from general terms that are widely used in the present invention while taking into account the functions of the present invention, but these may vary depending on the intention or custom of a person skilled in the art or the emergence of new technologies. In addition, in certain cases, there may be a term arbitrarily selected by the applicant, in which case the meaning thereof will be described in the description of the corresponding invention. Therefore, it is intended that the terminology used herein should be interpreted based on the meaning of the term rather than on the name of the term, and on the entire contents of the specification.

The present invention aims to increase the usability of an application by automatically matching the API (Application Programming Interface) of the application to the platform's control API so that the application can be executed regardless of the platform.

The platform refers to a hardware architecture or software framework in which an application can run, and includes an architecture and an operating system (OS) of a multimedia device, a programming language, and an associated runtime library or GUI. In other words, it means a hardware and software basis for running an application.

1 is a diagram illustrating an embodiment of a platform on which an application is run. In order for the application 150 to be driven, an operating system 120, a driver 130, and an API 140 may be installed between the hardware 110 and the application 150. Is provided to allow the application 150 and the hardware 110 to interact.

The driver 130 may be viewed as part of the operating system 120, and the operating system 120, the driver 130, and the API 140 are middleware. This middleware communicates with the device via a communication subsystem in conjunction with the hardware 110 and accepts comprehensive instructions from the application 150 and translates them into the low level instructions required by the hardware 110.

The middleware 220 includes various protocols and Java virtual machines for network connection on the OS / device management layer 225 for controlling and managing computer hardware and network access devices for compatibility with the hardware layer 230. A low level library layer 223 having low level libraries based on a programming language such as C) or C language is formed. In addition, the API layer 221 formed using the low-level library layer 223 is formed in the form of a library so that an application such as an electronic program guide (EPG) can be executed.

Therefore, the application developer has no choice but to be restricted by the platforms of the middleware 220 and the hardware layer 230 in order for the developed application to run on the multimedia device. Of course, if Java or Flash is used, the middleware 220 can be independently developed. However, in order to actually control the multimedia device, a function must be called to match an API provided by the hardware layer 230.

Accordingly, the present invention intends to propose a method for running an application independently of a platform that enables an application to be run on a platform other than a specific platform for an application developed based on a specific platform.

3 is a diagram showing an entire system including a multimedia device according to an embodiment of the present invention.

Of course, it is also possible, if necessary, to provide a broadcast receiving module and a decoder while not including the network interface 420, and conversely, to provide a network interface 420 and to include a broadcast receiving module and a decoder without the design. It is possible.

The broadcast receiving module receives a broadcast signal from an external source device. The broadcast signal includes all signals such as terrestrial, satellite, and cable broadcasts. The external source device may be a server or a satellite such as a broadcast station, a cable operator, a VOD operator, or the like.

As such, the multimedia device according to the present invention may reproduce broadcast program content according to a broadcast signal received through the broadcast receiver 410. In addition, other types of content corresponding to an external signal received from an external device can also be reproduced. The external signal may be received through the network interface 420 described later.

The network interface 420 may include, for example, an Ethernet terminal for connection with a wired network. In addition, for connection with a wireless network, wireless LAN (Wi-Fi), Wibro (Wireless broadband), World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA) communication standards, etc. Can be used.

In addition, the network interface 420 may select and receive a desired application from among applications that are open to the public through the network. Accordingly, the network interface 420 may exchange data with the application provider 600.

The external device interface 430 may connect the external device and the multimedia device 400. To this end, the external device interface 430 may include an A / V input / output unit (not shown) or a wireless communication unit (not shown).

The external device interface 430 may be connected to an external device such as a DVD (Digital Versatile Disk), a BD (Blu-ray Disc) player, a game device, a camera, a camcorder, a computer (laptop), or the like. have. In addition, the external device interface 430 may receive an application or a list of applications in a neighboring external device and transmit the received application to the controller 480 or the memory 440 or 470.

The first memory 440 and the second memory 470 may be implemented by an EEPROM (Electrically Erasable Programmable Read-Only Memory) or the like, and store a program for processing and controlling each signal in the controller 480, It may also store signal processed video, audio or data signals.

In addition, the first memory 440 and the second memory 470 may perform a function for temporarily storing an image, audio, or data signal input from the external device interface 430 or the network interface 420. have. In addition, an application or a list of applications input from the external device interface 430 or the network interface 420 may be stored.

In addition, the first memory 440 and the second memory 470 may exist in one memory form.

The user interface 490 transmits a signal input by the user to the controller 480, or transmits a signal from the controller 480 to the user. For example, the user interface 490 may be configured such as power on / off, channel selection, screen setting, etc. from the remote controller 700 according to various communication methods such as a radio frequency (RF) communication method and an infrared (IR) communication method. The control signal may be received and processed, or the control signal from the controller 480 may be transmitted to the remote controller 700.

The display unit 481 converts an image signal, a data signal, an OSD signal processed by the controller 480, or an image signal, data signal, etc. received from the external device interface 430 into R, G, and B signals, respectively. Create The display unit 481 may be a PDP, an LCD, an OLED, a flexible display, a 3D display, or the like.

The audio output unit 483 receives a signal processed by the controller 480, for example, a stereo signal, a 3.1 channel signal, or a 5.1 channel signal, and outputs a voice signal. The audio output unit 483 may be implemented with various types of speakers.

The power supply unit 485 supplies the corresponding power throughout the multimedia device 400. For example, power is supplied to the controller 480 that can be implemented in the form of a System On Chip (SOC), a display unit 481 for displaying an image, and an audio output unit 483 for audio output. Can be supplied.

The remote controller 700 sends user input to the user interface 490. To this end, the remote controller 700 may use Bluetooth, RF (Radio Frequency) communication, Infrared (IR) communication, UWB (Ultra Wideband), ZigBee (ZigBee).

In particular, the multimedia device 400 for driving an application independently of a platform will be described below.

The first memory 440 stores a matching table. The matching table stores information in which the application programming interface (API) of the application matches the control API of the platform in the form of a table.

An API is a language or message format used to communicate between an operating system and an application. It is implemented by calling a function that provides a link to a specific subroutine for execution within a program. Thus, an API has several program modules or routines that must already exist or be linked in order to perform the work requested by the function call.

If the API for the application and the control API of the platform of the multimedia device are the same, there is no problem in executing the application. However, if the API of the application and the control API of the platform are not the same function, it is inconvenient to develop or modify the application so that the API used in the application is the same as the control API of the platform.

Therefore, the present invention is to save the hassle of developing a separate application according to the type of platform through the additional work of matching the API of the application and the control API of the platform.

Therefore, the matching unit 450 matches the API of the application with the control API of the platform using the first memory 440. More specifically, the matching table is used to sequentially match the control API of the platform corresponding to each argument included in the API of the application.

FIG. 5 is a diagram illustrating an argument of an application API according to an embodiment of the present invention. When the multimedia device changes a channel with respect to a broadcast signal received, it is an argument of an application API for channel tuning.

In case of tuning the channel, the European model requires the frequencies 510 and 520 and the service IDs 530 and 540. In addition, for normal channel tuning, a modulation rate (symbol rate-550) or constellation type (560) is required, and concomitantly analog / digital and terrestrial waves. Arguments 570, such as / cable / satellite, need to be passed. In addition, the content of performing a special function, such as whether to show a channel banner (channel banner) when changing the channel may be included as an argument (570).

As such, there are arguments necessary for performing a particular function, and additionally necessary arguments. Therefore, the matching table requires that the application API must have the value as an argument for mandatory arguments, and the default value that is set if the value is not used in the application API for required arguments. A value can be used and optional arguments can be omitted or error reported.

FIG. 6 is a diagram illustrating an embodiment of a matching table according to the present invention, in which an application API is matched with a control API of a platform when a channel is changed.

The application API 610 which performs a channel change function called API_Euro_Channel_Change is matched with the control API 630 of the platform for each argument 620 belonging to the application API 610. Therefore, the control API of the platform can be more efficiently matched if the API includes only one argument.

In addition, as shown in FIG. 6, the argument type 640 may be stored together in the matching table to match the control API to the arguments of the application API. In the process of matching the control API of the platform corresponding to the argument included in the application API, the argument type of the application API may not match the argument type of the control API. Accordingly, the argument type 640 of the platform API may be stored, and the matching unit 450 may classify each argument included in the API of the application according to a preset argument type and match the control API of the platform. . For example, if an argument is of type float, it can be cast by type casting to int.

FIG. 7 is a diagram illustrating another embodiment of a matching table according to the present invention. FIG. 7 illustrates a table in which an application API related to IP when a channel is changed to a control API of a platform according to an argument of an application API. Accordingly, corresponding control APIs such as IP, PORT, channel name, channel number, channel type, and OSD setting information required for channel change are matched.

As described above, the control API having only one argument is described as an embodiment in order to configure the control API of the platform as the minimum functional unit. However, in some cases, the API cannot be executed using the API having only one argument. Therefore, matching with a control API having a plurality of arguments as necessary is also within the scope of the present invention.

8 is a view showing another embodiment of a matching table according to the present invention, an embodiment of a matching table for converting an application API related to a picture in picture (PIP) function into a control API of a platform in digital TV broadcasting An example is shown.

PIP is an on-screen screen that displays a small screen simultaneously from the screen of a multimedia device. It can be used to simultaneously display two channels on a personal computer (PC) window or television. have.

However, in the case of the non-PIP mode, since the information on the subchannel is not necessary, only the information on the main channel is needed. Accordingly, as shown in FIG. 8, necessary control information may be stored as a parameter, and a control API corresponding to each factor may be stored in a matching table.

FIG. 9 is a diagram illustrating another embodiment of a matching table according to the present invention. In FIG. 8, in case of the PIP mode, control for matching and matching information about the number and type of additional channels required additionally. The API is shown as a matching table. However, there is a difference that an argument for additionally necessary information may be replaced with a preset value when there is no corresponding matching table.

FIG. 10 is a diagram illustrating an embodiment in which a matching table according to the present invention is described in a description format. As illustrated in FIG. 10, the matching table describes an application API and a control API of a platform such as XML. Can be stored in (description) format.

As shown in FIG. 10, <Begin> <API 1> <API 2> ... <API n> <End> may be configured. In <Begin>, an application API function name and type to be converted are given. In <End>, you can get the type of result to return. In the middle, it is possible to define a function name of a series of control APIs, arguments and argument types passed to the control API, and the like. In this way, the data of the matching table can be extended by storing in the description format.

Therefore, when the application is executed, the controller 480 calls the control API of the platform according to the matching result of the matching unit 450. However, if necessary, the driving unit 460 to call the control API of the platform also belongs to the scope of the present invention. The driving unit 460 will be described later.

Meanwhile, the matching table may generate a matching table using the platform control API provided from the platform provider 500 before the application provider 600 develops the application. In addition, the created matching table can be distributed together with the application distribution.

In this case, the driver 460 determines whether a matching table is required while loading the application into the second memory 470. That is, it is determined whether the application is developed based on the platform. As a result of the determination, a matching table is required if the platforms used for development are different. Therefore, a matching table included in load data for loading an application is extracted and stored in the first memory 440.

However, the application provider 600 may not be the target platform in the process of developing the application, but there may be a case where the application must be executed on a specific platform.

In such a case, the network interface 420 may receive data for generating a matching table from an external server, for example, the application provider 600. In this case, the controller 480 may generate a matching table using the received data and store the matching table in the first memory 440.

The data for generating the matching table may include a type of an application API, a function and definition information of each API, and include a definition of whether an argument included in each API is a required argument, a required argument, or an additional argument. Can be.

Required arguments are required arguments to run the API. Required arguments are required arguments to execute the API, but the arguments are allowed to run the application using the default value. Means.

As described above, the arguments are divided into mandatory arguments, required arguments, and additional arguments, thereby making it easy to match control APIs corresponding to application API arguments. However, if it is a required argument and the corresponding control API does not exist, it is difficult to execute the application, so that an error can be sent to an external server.

In addition, since the information on the control API is already included in the multimedia device 400, it does not need to be separately received. However, the data for generating the matching table may also include information about the control API as necessary.

The controller 480 may control the control API corresponding to the application API to be called using the received data when the application is executed, without generating a matching table separately. Alternatively, after the application is loaded, the code for executing the application is converted into a code using a control API by using the received data to control to use the converted code when the driver 460 tries to execute the application. It may be.

As described above, by matching the application API and the control API, there is an effect of increasing the compatibility of the application platform. As a result, it supports various application service areas of application developers and service providers.

FIG. 11 is a flowchart illustrating a control method of a multimedia device for driving an application independently of a platform according to an embodiment of the present invention. Referring to FIG. 11, a control method of a multimedia device for driving an application independently of a platform will be described.

The application is loaded into memory (S1100). It is determined whether a matching table exists in the loaded application-related data (S1110). If not, data for generating a matching table is received from an external server (S1120).

The data for generating the matching table may include a type of an application API, a function and definition information of each API, and include a definition of whether an argument included in each API is a required argument, a required argument, or an additional argument. Can be.

Required arguments are required arguments to run the API. Required arguments are required arguments to execute the API, but the arguments are allowed to run the application using the default value. Means.

As described above, the arguments are divided into mandatory arguments, required arguments, and additional arguments, so that the control API corresponding to the application API arguments can be easily matched. However, if it is a required argument and the corresponding control API does not exist, it is difficult to execute the application, so that an error can be sent to an external server.

The data for generating the matching table may further include a control API list corresponding to an argument of an application API or a list of control APIs corresponding to an application API.

A matching table is generated using the received data (S1130). The matching table includes control API information of the platform matching each argument included in the API of the application, and may be in a description format.

In addition, the control API of the platform matched in the matching table may be an API including only one argument, and after classifying each argument included in the API of the application according to a predetermined argument type to the control API of the platform. Can match.

Meanwhile, the generated matching table is stored in a memory (S1140), and the memory may be the same as or different from the memory in which the application is loaded.

When the execution request of the application is received (S1150), the API of the application is matched with the control API of the platform using the matching table (S1160). In this case, when there is no control API of the platform corresponding to the argument included in the API of the application, an error may be reported to the external server.

According to the matching result, an application is executed by calling the control API of the platform (S1170).

Furthermore, although the drawings are shown for convenience of explanation, it is also possible to design a new embodiment to be implemented by merging the embodiments described in each drawing. It is also within the scope of the present invention to design a computer-readable recording medium in which a program for executing the previously described embodiments is recorded according to the needs of those skilled in the art.
