1. Field of the Invention
The present invention relates to a media playback apparatus capable of testing a user application and a method for testing a user application using the same, and more particularly, to a media playback apparatus capable of testing a user application which is generated by executing a developer application in a computing apparatus, and a method for testing a user application using the same.
2. Description of the Related Art
A Blu-ray disc (referred to as “BD” hereinafter) provides not only HD images through a Blu-ray disc player (referred to as “BDP” hereinafter) but also various user applications executed in the BDP.
A user can be provided with a service by selecting a desired user application from various user applications stored in a BD and executing the selected user application. For example, when the user selects and executes a VOD application, a BDP accesses a VOD server to provide video selected by the user in real time.
A user application executed in a BDP is generated by compiling a source code configured in JAVA.
Referring to
To test and debug the generated user application, the user stores the user application in a storage unit 20 such as a BD. The user inserts the storage unit 20 into a media playback apparatus 30 to execute the user application stored in the storage unit 20.
The media playback apparatus 30 outputs a debugging message and a log message, which are generated by the user application, through a display unit 40.
The user corrects and compiles the source code with reference to the debugging message and the log message and repeats the above-mentioned procedure.
In the conventional user application development environment, it is necessary to store a corrected user application in the storage unit 20 to test and debug the corrected user application whenever a source code is corrected.
Particularly, to test a user application executed in a media playback apparatus using a disc storage device such as a BD, an additional recording device capable of recording a user application in the disc storage device is required, resulting in additional costs for implementing an application development environment. Even when the disc storage device includes the recording device, the user has to insert the disc storage device on which a user application is recorded into the media playback apparatus, and test and debug the user application whenever the user application is corrected.
Furthermore, the user needs to check a debugging message and a log message, generated during a test and debugging process, through a display unit. Accordingly, if a plurality of debugging messages and log messages are generated, the user may not check some of the messages and may not store the debugging messages and log messages.
To solve these problems, there has been proposed a method of testing and debugging a user application by installing media player simulation software in a computing apparatus.
However, because the simulation software cannot implement the same test environment as a physical media player, even a user application, which is executed without generating an error in the test environment of the simulation software, can frequently generate errors when executed in the physical media player.
An object of the present invention is to provide a media playback apparatus capable of testing a user application which is generated by executing a developer application in a computing apparatus such that applications stored in a plurality of computing apparatuses can be tested using a single media playback apparatus, and a method for testing a user application using the same.
The object of the present invention can be achieved by providing a media playback apparatus including: a storage unit storing one of a developer application and information about a download link of the developer application; a processor executing the developer application; and a communication unit communicating with a computing apparatus which generates user applications, under the control of the processor, wherein the developer application includes: a first instruction for transmitting a user application information request to the computing apparatus through the communication unit; a second instruction for receiving information about one or more user applications, transmitted from the computing apparatus in response to the user application information request; a third instruction for transmitting, to the computing apparatus through the communication unit, a user application request for a user application selected with reference to the information about user applications; a fourth instruction for receiving the user application transmitted from the computing apparatus in response to the user application request through the communication unit; and a fifth instruction for executing the user application received according to the fourth instruction to test the user application.
The developer application may be based on Java.
The developer application may further include a sixth instruction for transmitting debugging information generated by executing the selected user application to the computing apparatus.
The developer application may further include a seventh instruction for transmitting the debugging information to the logging server.
The processor may download the developer application from a developer application storage server according to the download link and execute the developer application.
The developer application may further include an eighth instruction for transmitting a configuration request for configuration information of the computing apparatus to the computing apparatus.
The developer application may further include a ninth instruction for displaying the configuration information and the information about user applications on a display unit before the third instruction is executed.
The media playback apparatus may include a Blu-ray disc player.
The object of the present invention can be achieved by providing a method for testing a user application executed in a media playback apparatus including a storage unit storing one of a developer application and information about a download link of the developer application; a processor executing the developer application; and a communication unit communicating with a computing apparatus generating a user application, under the control of the processor, the method including steps of: (a) transmitting a user application information request to the computing apparatus through the communication unit; (b) receiving information about one or more user applications, transmitted from the computing apparatus in response to the user application information request; (c) transmitting, to the computing apparatus, a user application request for a user application selected with reference to the information about user applications; (d) receiving the user application transmitted from the computing apparatus in response to the user application request through the communication unit; and (e) executing the received user application to test the user application.
The user application may be based on Java.
The method may further include step of (f) transmitting debugging information generated in the step (e) to the computing apparatus.
The method may further include step of (g) transmitting the debugging information to a logging server.
The method may further include step of (h) downloading the developer application according to the download link prior to the step (a).
The method may further include step of (i) transmitting a configuration request for configuration information of the computing apparatus to the computing apparatus prior to the step (a).
The method may further include step of (j) displaying the configuration information and the information about user applications on a display unit prior to the step (c).
The media playback apparatus may include a Blu-ray disc player.
The media playback apparatus capable of testing a user application and a method for testing a user application using the same according to the present invention have the following advantages.
Since a user application which is generated by executing a developer application in a computing apparatus connected to the media playback apparatus through a network is tested, applications stored in a plurality of computing apparatuses can be tested using a single media playback apparatus. Accordingly, it is unnecessary for the media playback apparatus to include an additional recording device that records user applications on a disc.
In addition, a user can select and test a user application displayed through a display unit connected to the media playback apparatus according to the present invention. Therefore, the user can easily test the user application without inserting a disc storage device storing the user application into the media playback apparatus and testing and debugging the user application whenever the user application is corrected.
Furthermore, the user can easily check a debugging message generated during a test and debugging procedure since the debugging message is stored in a computing apparatus or a logging server.
Moreover, a user application can be easily and correctly tested even if simulation software of the media playback apparatus is not used.
Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
These and/or other aspects and advantages of the invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
