At least one key button 32 for receiving a recording instruction, a storage unit 33 storing the reserved recorded content file, and a communication unit selectively mounted on the receiver 30 to perform a mobile communication service through a mobile communication network; A module 34, a broadcasting module 35 for demodulating and decoding the mobile multimedia broadcasting signal and displaying the decoded broadcasting signal on the display unit 31, and separating an EPG signal from the CDM signal to separate the EIT signal of the EPG signal. A signal analyzer 36 for transmitting the analysis result to the controller; And a controller 37 that receives a reservation recording instruction from a user and performs reservation recording through the interpreted EIT signal.

At this time, the receiver 30 of the above embodiment, for convenience of description, but receiving satellite DMB (Digital Multimedia Broadcasting) transmitted from the broadcasting center 10 through the satellite system 20 as an example, the terrestrial DMB of It will be appreciated by those skilled in the art that the receiver is the same or very similar.

The reservation recording service method of mobile multimedia broadcasting according to the preferred embodiment of the present invention configured as described above will be described. The present embodiment is an operation performed by the control unit 37 of the mobile multimedia broadcasting receiver 30.

First, upon receiving a recording instruction of a program currently being broadcast, it is checked whether the recording instruction is immediately recorded (S301-S302). For example, if the key button 32 has been pressed for at least 2 seconds or longer, it is determined as recording immediately, and if " reserved recording " displayed on the display unit 31 is selected, it is determined as reserved recording.

If the recording result is immediately confirmed, it is determined whether the channel currently being watched is a channel capable of recording (S303).

As a result of the determination, if it is a recordable channel, it is checked whether the existence of the content file to be recorded is stored in the receiver 30 itself storage unit 33 (S304), and if the file is not found, the recording starts (S305). If the file is present, the display unit 31 notifies that the content file to be recorded currently exists, and then duplicate recording or canceling recording according to an instruction input from the user (S306). In this case, in case of duplicate recording, the extension is different from the existing file.

In addition, as a result of the determination, if the channel is not recordable, the display unit 31 is notified that the channel is not recordable or the recording execution command is ignored (S307).

At this time, whether recording is possible or not is determined by analyzing a predetermined identifier (Service_type of SDT) included in the EPG signal and transmitted. On the other hand, if it is determined in the step 302 that the reservation recording, recording is performed from the next program of the program currently being broadcast (S308). At the same time, the display unit 31 indicates that the reserved recording is in progress in a predetermined color (for example, green), cancels the reserved recording in the opposite part, and indicates that the program is to be reserved in another color in the next program name. (S309).

Accordingly, when the program proceeds to the next program, the process proceeds in the same manner as the steps 303 to 307 (S310-S314). That is, it is checked whether the channel to be reserved recording is a recordable channel, and after confirming that the same content file exists in the storage unit 33, the reserved recording is performed.

On the other hand, when the program being scheduled recording ends, recording ends (S315-S316). When the subscriber activates the automatic reservation recording function, when the next program starts, recording starts immediately (S317-S318). However, if the subscriber does not activate the automatic reservation recording function, recording ends.

When the automatic scheduled recording is activated, when the scheduled recording is executed in the recording-capable channel, the scheduled recording proceeds from the initially set program and continues until it is terminated immediately.

Thereafter, when the reserved recording end or cancel button is input from the user, or when the capacity of the storage unit 33 is exceeded, the process ends immediately (S319). Then, the process is repeated from step 315 to step 319.

At this time, when moving to another channel or accessing the wireless Internet during the recording, after storing the program recorded so far to the storage unit 33, and automatically cancels the reservation recording.

In this manner, reservation recording is performed, and thus reservation recording is performed for each program.

On the other hand, with reference to Figures 6 to 7 will be described respectively the charging method for the reservation recording service of mobile multimedia broadcasting according to an embodiment of the present invention.

1) A method of charging a reservation recording service for mobile multimedia broadcasting based on PPC.

The pay per channel (PPC) refers to a channel that can be viewed only by subscribers who additionally pay a monthly fee in addition to the basic fee. In this case, since the PPC is charged in units of channels, there may be several PPC channels, and the subscriber may subscribe to each PPC channel.

First, channel 1 on which a predetermined program is broadcast is copied to channel 2 (S401). Such channel copying is almost infinite regardless of the number of channels, and after copying, the same program is broadcast in channel 1 and channel 2 only by different channel numbers. That is, channels 1 and 2 have the same EPG and different SDTs.

Subsequently, the channel 1 is set to a channel that cannot be recorded or reserved, and the channel 2 is set to be capable of recording or reserved recording (S402-S403). This setting is made before the broadcasting center 10 transmits the mobile multimedia broadcasting.

Thereafter, the channel 1 is set as a channel package for the base rate, and the channel 2 is set as a PPC requiring an additional fee (S404-S405). Accordingly, the subscriber paying only the basic rate can use only channel 1, and the corresponding PPC subscriber can use the recording or reservation recording function through channel 2.

2) A method of charging a reservation recording service for mobile multimedia broadcasting based on SMS or CAS.

First, a predetermined channel is set as a non-recordable or reserved recording channel and included in the base rate channel package (S501). At this time, the subscriber who wants to use the reservation recording for the channel pays an additional fee and activates the reservation recording. The method of activating or deactivating the reservation recording may be performed through SMS or Conditional Access System (CAS) of the receiver 30.

For example, when a subscriber requests a reservation recording service while watching a mobile multimedia broadcast, the receiver 30 displays a dialog on the display unit asking whether to subscribe to the reservation recording service, and then the subscriber subscribes to the reservation recording service through ARS or wireless Internet. Upon request, SMS is activated to activate the reservation recording function of the subscriber's receiver (S502-S504). However, if the additional subscription is not applied, it is displayed on the display unit 31 that reservation recording is not possible (S505).

While the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will recognize that various modifications or changes can be made without departing from the spirit and scope of the invention.

As described above, according to the present invention, by providing a subscriber with a reservation recording service while watching a broadcast through a mobile multimedia broadcasting receiver, the subscriber can easily and easily record a desired program.

In addition, according to the present invention, by providing a reservation recording service to the subscriber while watching the broadcast through the mobile multimedia broadcasting receiver, it is possible to diversify the mobile multimedia broadcasting service to expand the subscriber.

In addition, according to the present invention, there is an effect that can generate a variety of revenue sources through the charge for the reservation recording service of the mobile multimedia broadcasting.
