The present invention relates to a DMB group reservation recording method in a mobile communication terminal. More specifically, the Wireless Internet Platform for Interoperability (WIPI) and Digital Multimedia Broadcasting (DMB) reception functions are integrated to add DMB reception capabilities to the WIPI environment. And a group reservation recording and viewing method for DMB broadcasting in a mobile communication terminal using WIPI, which can simultaneously use a DMB broadcasting receiving function.

The mobile communication system has been developed through the first generation analog AMPS (Advanced Mobile Phone System), the second generation cellular (Cellular) and personal communication service (PCS), and recently, the third generation high-speed data. International Mobile Telecommunication-2000 (IMT-2000) has been developed. The 1X system and the EV-DO system are called 2.5 generations because they use the same frequency band (800 MHz, 1.8 GHz) as the second generation of cellular / PCS services and provide some of the IMT-2000 functionality called the third generation. .

In the first and second generation schemes, voice communication is mostly performed using a mobile communication terminal, and data communication has been extremely limited. However, with the advent of 2.5 generation and 3 generation systems due to the steady development of mobile communication technology, the mobile terminal has recently become a core tool for performing data communication.

Recently, with the development of internet and multimedia data technology, a content provider (CP) that provides various contents such as multimedia communication, network game, and video game has emerged, and various services provided by the content provider are provided to mobile communication terminals. The number of mobile subscribers to use has increased.

Therefore, using a wireless machine based on a virtual machine as a wireless internet environment, a mobile device can run embedded applications that are embedded when a mobile terminal is released, or content provided by a content provider on an information server. Generated as an application running on a wireless Internet platform (transmission) and transmitted to a mobile communication terminal carried by a mobile subscriber through a mobile communication network, and the downloaded mobile communication terminal is running the application on the provided wireless Internet platform.

However, as the wireless Internet service using the wireless Internet platform has been in the spotlight, mobile communication providers providing mobile communication services have different wireless Internet in order to promote the excellence of mobile communication services provided by each and to differentiate mobile communication services. The platform was developed to provide wireless Internet service. Wireless SK Telecom's GVM, SKVM, MAP and LG Telecom's KVM are examples of wireless Internet platforms developed by mobile operators. As a result, the wireless Internet platform has been changed depending on the mobile operator, causing the application to be incompatible.

In addition, the time required to create an application because a content provider that provides content to a mobile operator must also make an application suitable for each wireless carrier platform provided by each carrier and provide it to each mobile operator. And cost increased.

To address this inefficiency, WIPI was born with the intention of unifying wireless Internet platforms that are developed and used differently by mobile carriers, and contents providers developing applications suitable for unified wireless Internet platforms.

Wireless Internet Platform for Interoperability (WIPI) is a mobile standard platform specification that is provided in a mobile communication terminal to provide an environment for executing an application. A platform that satisfies WIPI (hereinafter referred to as 'WIPI') ensures the compatibility of applications for mobile operators developing applications for mobile terminals, and makes it easy to port the wireless Internet platform to mobile terminal developers. In addition, it provides various and rich contents services to mobile subscribers.

On the other hand, the conventional DMB (Digital Multimedia Broadcasting) to explain, currently in use as a radio broadcast in the form of a fixed reception for the reception while walking or while driving the vehicle, the sound quality is significantly reduced, high output and a wide frequency band In order to solve this problem, the standardization and commercialization of digital audio broadcasting is progressing all over the world.In Europe, which adopts Eureka-147 as the digital audio broadcasting standard, DAB (Digital Audio Broadcasting) in Europe, Digital Audio Radio), Digital Radio Broadcasting (DRB) in Canada, and Digital Sound Broadcasting (DSB) in the International Telecommunication Union (ITU-R), and Digital Multimedia Broadcasting (DMB) by the Ministry of Information and Communication in Korea. It is used as the name.

DAB, developed for next-generation broadcasting, is able to receive CD-level sound quality in vehicles that run at high speeds even when transmitted at low power due to strong radio wave environment and noise in urban areas. In addition, the concept of 'broadcasting broadcasting' is expanded to the concept of 'broadcasting broadcasting'. In addition to music broadcasting, various multimedia information such as news, traffic information, weather information, geographic location information, video information, etc. Can be transmitted graphically.

On the other hand, DMB, or digital multimedia broadcasting, named by the Ministry of Information and Communication of Korea, is digitalized for voice broadcasting, and beyond the existing AM and FM radio forms, it provides 1.5 Mbit / s of data from high-quality CD-quality sound, text, graphics or moving pictures. It is the next generation broadcasting that provides various data services that can be transmitted, bidirectionality, and excellent mobile reception quality.

As described above, DMB can be broadly classified into terrestrial DMB and satellite DMB according to the characteristics of a medium, which is a means of transmission. In the case of satellite DMB broadcasting, it can be divided into fixed service and mobile service.

The characteristics of the DMB are described below by the contents of the European Broadcasting Union (EBU) and ITU-R.

(1) DMB broadcasting should be a digital transmission system that guarantees high quality, and must be continuously acceptable for the next 50 years, and provide high quality sound of 2 channels or more.

(2) It should be able to receive without obstacles in portable and running cars. In other words, mobile, portable and fixed batch reception should all be possible.

(3) A data channel (PAD: Program Associated Data) that transmits additional information to a regular program or a data channel (NPAD: NonPAD) service as an independent program should be available. For example, radio, text information and program recognition should be available.

(4) A system with high transmission capacity and transmission efficiency, such as accommodating different data channel capacity and increasing frequency utilization efficiency.

In addition, an electronic program guide (EPG) of the DMB reception function performs a function of receiving program information according to a DMB broadcasting channel and providing the same to a viewer. You can select a channel, watch or record it, or register a channel you watch often.

Therefore, by integrating the WIPI environment with the DMB broadcast reception function, the DIP reception function can be added to the WIPI environment to develop an application that uses various functions related to wireless Internet and the DMB broadcast reception function simultaneously. Can provide users with convergence services, but the WIPI environment and DMB are not integrated yet.

In order to solve the above problems, the present invention integrates a wireless Internet standard platform (WIPI: WIPI) and a DMB (Digital Multimedia Broadcasting) reception function to integrate a DMB reception function in a WIPI environment. In addition, it is possible to simultaneously use various functions related to wireless Internet and DMB broadcasting reception function, and to provide a method of group reservation recording and viewing of DMB broadcasting in a mobile communication terminal using WIPI.

In order to achieve the above object, the present invention provides a method for group reservation recording of a Digital Multimedia Broadcasting (DMB) program on a mobile platform of a mobile communication terminal that executes a mobile communication service provided by the mobile communication network using a mobile communication network. (a) receiving a program number n and reservation information from an electronic program guide (EPG: hereinafter called 'EPG'); (b) checking whether the program number n exceeds 1; And (c) generating a group reservation information and storing it in a registry when the number of programs (n) exceeds 1 as a result of checking in step (b). Provide a recording method.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a block diagram illustrating a conceptual structure of a WIPI according to a preferred embodiment of the present invention.

The mobile communication terminal hardware and the DMB hardware 110 are composed of a hardware device constituting the mobile communication terminal, a DMB hardware device capable of receiving and viewing DMB broadcasts, and software for performing basic functions of the mobile communication terminal. Herein, the mobile terminal hardware includes a microprocessor controlling all devices and overall functions of the mobile terminal, a nonvolatile memory utilized as a storage device, and a random access memory capable of temporarily storing and randomly accessing data. Random access memory), a user interface unit, a digital signal processor, a baseband converter, an RF signal processor, and the like, and the DMB hardware includes a receiver for receiving the DMB, a display unit for outputting the DMB, and the like. In addition, the basic software includes software for performing basic functions of mobile communication performed by the mobile communication terminal and drivers of various devices.

The mobile terminal adaptation layer (HAL) 120 is a layer for supporting hardware independence in the mobile terminal manufacturer's porting of the wireless Internet platform to the mobile terminal. This creates an abstraction for mobile terminal hardware and DMB hardware, and configures the wireless Internet platform independently of the hardware. That is, the upper layers operate regardless of the basic software of the mobile communication terminal through the HAL 120.

The WIPI real-time engine 130 is an engine implemented using only a standardized application program interface (API) of the HAL 120.

The registry 140 receives and stores reservation information and group reservation information from the WAM 170 and transmits reservation information and group reservation information to the EPG 182 when a reservation information and group reservation information request signal is received from the EPG 182. It plays a role. In addition, the registry 140 is configured as a nonvolatile memory that does not erase the pre-stored reservation information even when the application is terminated or the power of the mobile communication terminal is turned off.

The DMB API 150 provides C and Java APIs as a collection of DMB APIs that can watch DMB and essential APIs supported by the wireless Internet platform. The DMB API controls the registry 140 and DMB hardware, and performs a function of tuning a broadcast channel and playing or recording a specific program on the screen. Essential APIs include Mobile Standard Foundation (MSF), Mobile Standard Profile (MSP), Connected Limited Device Configuration (CLDC), and Mobile Information Device Profile (MIDP). Here, MSF is a basic API for portable devices and supports input / output functions, networks, security, internationalization, and the like. MSP is a profile for MSF-based portable devices. CLDC is a configuration for virtual machine-based portable devices. CLDC consists of a virtual machine and a core API. MIDP is an overview for CLDC based portable devices.

The dynamic component 160 is an API and components added or updated through the WIPI Application Manager (WAM) (hereinafter, referred to as WAM) 170.

The WAM (WIPI Application Manager) 170 performs an application management function such as downloading, installing, and deleting an application, and adds or updates an API and components (DLL: Dynamic Linking Library). It is called 'DLL') It performs management function.

The WAM 170 according to the preferred embodiment of the present invention executes the EPG 182 to allow the user to be provided with a broadcast program guide, and the broadcast program reservation recording / viewing function, the broadcast program channel number, and the broadcast from the EPG 182. Reservation information including at least one of a program start time and a broadcast program end time is received. In addition, when the user selects a plurality of broadcast programs, the WAM 170 receives the number of broadcast programs n from the EPG 182.

According to a preferred embodiment of the present invention, the WAM 170 checks whether the received broadcast program number n exceeds 1, and if the check result exceeds 1, includes a broadcast program number n and reservation information. The group reservation information is generated and stored in the registry 140. The EPG 182 is registered in the alarm application in order of the program having the fastest start time by comparing the start time of each broadcast program using the group reservation information of the WAM 170, and the execution time of the alarm application is the broadcast program of the group reservation information. It is set equal to the start time. The WAM 170 checks whether the execution time of the alarm application has arrived, and when the check result indicates that the execution time of the alarm application has arrived, the WAM 170 executes the EPG 182 and then groups from the registry 140. Receive reservation information. The WAM 170 changes the channel to a preset broadcast program channel number using the received group reservation information and then records or views the broadcast program until the broadcast program end time.

On the other hand, when the number of broadcast programs n does not exceed 1, the WAM 170 stores reservation information in the registry 140 and registers the EPG 182 in the alarm application. Here, the execution time of the alarm application is set to the same time as the preset broadcast program start time. For example, when the broadcast program channel number is' channel 11 'and the broadcast program start time is '21 o', the execution time registered in the alarm application is set to '21 o 'which is the same as '21 o'. In addition, the WAM 170 terminates the EPG 182 and determines whether a preset alarm application execution time has arrived. As a result of the check, when the execution time arrives, the WAM 170 performs a function of executing the EPG 182 registered in the alarm application.

The application 180 is a wireless Internet such as e-mail, location-based services, games, characters / bells, video streaming, multimedia message services, and electronic program guides (EPGs, hereinafter referred to as EPGs) 182. A collection of various applications running on the platform.

The EPG 182 is a WIPI application made of a conventional electronic program guide, and is an application that provides DMB broadcasting information to a user using the registry 140 and the DMB API 150.

EPG 182 according to a preferred embodiment of the present invention receives the reservation information including one or more information of the broadcast program reservation recording / viewing function, the broadcast program channel number, the broadcast program start time and the broadcast program end time selected by the user The WAM 170 is transmitted to the WAM 170, and when the user selects a plurality of broadcast programs, the program receives the number n of broadcast programs and transmits the same to the WAM 170. In addition, the EPG 182 receiving the control command from the WAM 170 changes the broadcast channel according to the preset broadcast program channel number and performs recording until the preset broadcast program end time.

2 is a flowchart illustrating a method of reservation recording of DMB in a mobile communication terminal using WIPI according to an embodiment of the present invention.

If the user intends to reserve the DMB broadcast by using the mobile communication terminal, the WAM 170 executes the EPG 182 to provide the program guide to the user. Reservation information including at least one of a program channel number, a broadcast program start time, and a broadcast program end time is received (S210). For example, when the user executes the EPG 182, the time and title of the broadcast program corresponding to the date are outputted on the display unit of the mobile communication terminal, and the user outputs the broadcast program channel number (channel 11) and the broadcast program start time 21 O) Broadcast program end time (22:00), broadcast program reservation recording / viewing function (reservation recording) can be selected.

The WAM 170 stores the reservation information in the registry 140 (S220). Here, the registry 140 is configured as a nonvolatile memory that does not erase the reserved information even when the application is terminated or the power of the mobile communication terminal is turned off.

The WAM 170 registers the EPG 182 in the alarm application, and the execution time of the alarm application is set to be equal to the preset broadcast program start time (S230). Here, the alarm application function is a function of automatically executing the pre-registered EPG 182 when the preset execution time. For example, when the broadcast program channel number is' channel 11 'and the broadcast program start time is '21 o', the execution time registered in the alarm application is set to '21 o 'which is the same as '21 o'.

The WAM 170 receives a key operation from the user of the mobile communication terminal and terminates the EPG 182 (S240). In addition, when the user watches another broadcast program without ending the EPG 182, the EPG 182 may be driven until the program start time of the broadcast channel to be viewed or recorded.

The WAM 170 determines whether the execution time of the alarm application has arrived (S250).

As a result of checking in step S250, when the execution time is reached, the WAM 170 drives the alarm application to execute the EPG 182 (S260), and the WAM 170 schedules recording / viewing of the broadcast program from the registry 140. In operation S270, reservation information including one or more of a function, a broadcast program channel number, a broadcast program start time, and a broadcast program end time is received. For example, when the broadcast program start time is set to '21 o ', the alarm application execution time is also set to '21 o', so when WAM 170 arrives at the '21 o'clock, the EPG (registered in the alarm application) 182, the WAM 170 sends a broadcast program reservation recording / viewing function (recording), a broadcast program channel number (channel 11), a broadcast program start time (21 o'clock), and a broadcast program end time (from the registry 140). Reservation information including one or more pieces of information).

The WAM 170 changes the channel according to the preset broadcast program channel number using the reservation information (S280), and determines whether the reserved recording function is set according to the preset broadcast program reserved recording / viewing function (S290). ). For example, the WAM 170 changes the broadcast channel to 'channel 11' according to the broadcast program channel number, and determines whether the 'reserved recording' function is set according to the broadcast program reserved recording / viewing function.

When the reservation recording function is set as a result of checking in step S290, the WAM 170 records the broadcast program until the preset broadcast program end time using the EPG 182 (S292). For example, when the 'scheduled recording' function is set, the WAM 170 records the broadcast program of 'channel 11' until '22: 00 'using the EPG 182.

 If the reservation recording function is not set as a result of checking in step S290, the WAM 170 determines whether the reservation viewing function is set according to the broadcast program reservation recording / viewing function of the reservation information (S294). When the reservation viewing function is set as a result of checking in step S294, the WAM 170 executes the broadcast program until the preset broadcast program end time using the EPG 182 (S296). For example, a broadcast program of channel 11 is executed until 22:00.

3 is a flowchart illustrating a method for group reservation recording of DMB in a mobile communication terminal using WIPI according to an embodiment of the present invention.

The DMB broadcaster sends a group reservation recording information SMS including a plurality of broadcast program information to the mobile communication terminal (S310). For example, the DMB broadcaster generates and sends a group reservation recording information SMS including a plurality of World Cup related broadcast programs to the user, thereby enabling the user to make a group reservation recording.

After receiving the group reservation recording information SMS, the mobile terminal transmits a plurality of program information included in the group reservation recording information SMS to the WAM 170, and the WAM 170 executes the EPG 182 to perform group reservation recording information. A plurality of program information included in the SMS is output (S320).

The WAM 170 executes the EPG 182 to provide a plurality of program information to the user, and receives the number (n) of broadcast programs selected by the user and the reservation information from the EPG 182 (S330). Here, the reservation information includes at least one of broadcast program reservation recording / viewing information, broadcast program channel number, broadcast program start time, and broadcast program end time. For example, when the user selects three broadcast programs from among a plurality of broadcast programs, the number of broadcast programs is 'n = 3', and the scheduled recording / viewing function according to each program, the broadcast program channel number (11), the broadcast The program start time (20 o'clock) and the broadcast program end time (24 o'clock) are received.

The WAM 170 checks whether the received program number n exceeds 1 (S340).

As a result of checking in step S340, when the number of programs n exceeds 1, the WAM 170 generates group reservation information including the number of programs n and the reservation information and stores them in the registry 140 ( S350).

The EPG 182 is registered in the alarm application in order of the program having the fastest start time by comparing the start time of each broadcast program using the group reservation information of the WAM 170, and the execution time of the alarm application is the broadcast program of the group reservation information. It is set equal to the start time (S352).

The WAM 170 checks whether the execution time of the alarm application has arrived (S354).

As a result of checking in step S354, when the execution time of the alarm application arrives, the WAM 170 receives the group reservation information from the registry 140 after executing the EPG 182 (S360).

The WAM 170 changes the channel to the preset broadcast program channel number by using the received group reservation information, and then records or watches the broadcast program according to the broadcast program reservation recording / viewing function until the broadcast program end time (S362).

The WAM 170 checks whether there is a program registered in the alarm application (S364). As a result of checking in step S364, if there is a program registered in the alarm application, the process returns to step S354 and is performed again.

As a result of checking in step S340, when the number of programs n does not exceed 1, the WAM 170 selects one or more of a broadcast program reservation recording / viewing function, a broadcast program channel number, a broadcast program time time, and a broadcast program end time. General reservation information is generated and stored in the registry 140 (S370).

The WAM 170 registers the EPG 182 in the alarm application, and the execution time of the alarm application is set to be the same as the broadcast program start time (S372).

The WAM 170 checks whether or not the execution time of the alarm application has arrived (S374). When the execution time of the alarm application arrives as a result of the check in step S374, the WAM 170 executes the EPG 182. After that, the general reservation information is received from the registry 140 (S376).

The WAM 170 changes the channel to a preset broadcast program channel number by using the received general reservation information, and then records or watches the broadcast program according to the broadcast program reservation recording / viewing function until the preset broadcast program end time (S378). ).
