Meanwhile, digital multimedia broadcasting (DMB) is a new broadcasting service that digitally modulates various multimedia signals such as voice and video to receive broadcasts on the go. There are two types of terrestrial DMB and satellite DMB. In other words, digital multimedia broadcasting (DMB) is a new broadcasting service in which broadcasting and communication are converged, terrestrial DMB broadcasting using the frequency bands of VHF channel 8 (180-186 MHz) and VHF channel 12 (204-210 MHz), and 2.6. It is divided into satellite DMB that broadcasts using S-band frequency of GHz band. Each DMB allocates video channel, radio channel and data broadcasting channel. For terrestrial DMB, video standard is MPEG-4 PRAT10 AVC (H.264), audio standard is MPEG-4 PART3 BSAC, and data broadcasting standard is MPEG. -4 The broadcast standard has been adopted as the BIFS (Binary Format for Scene).

DMB terminals for such DMB broadcasting are largely divided into satellite DMB terminals and terrestrial DMB terminals, and terminal types include a mobile phone integrated terminal and a dedicated terminal combined with a vehicle terminal or a laptop.

First, according to the present invention, a 'broadcast reception VM' 162 is provided to provide real-time TV broadcasting and radio broadcasting like a DMB terminal using an existing CDMA network (1X, EVDO, etc.) without any new investment or change in a general older terminal. It can be downloaded through the wireless Internet gateway 210. The broadcast reception VM 162 includes a viewer function for receiving a broadcast, a remote control function for selecting a broadcast channel, and the like. Examples of broadcast channels in the embodiment of the present invention are shown in Table 1 below.

TABLE 1

division channel TV  MBC = mms: //211.xx.xx.xx.  KBS = mms: //211.xx.xx.xx. radio  FMMBC = mms: //211.xx.xx.xx.  FMKBS = mms: //211.xx.xx.xx.

Referring to FIG. 4, the broadcast reception VM 162 is downloaded to the mobile terminal 100 by accessing the wireless internet gateway 210 through the wireless internet network (S1).

Subsequently, the desired broadcast CH is selected by using the broadcast receiving VM 162 downloaded from the mobile terminal 100 and the connection is clicked (S2). Accordingly, the broadcast server 220 or 230 of the selected broadcast channel is connected through the CDMA network (1X, EVDO, etc.) to receive the broadcast through the mobile terminal 100 to view the broadcast (S3, S4). In the case of 1X network, connect with SVC OP = 33 (16x connection).

In step S4 of receiving and watching a broadcast, as shown in FIG. 5, the screen size is adjusted to be suitable for viewing according to the geomagnetic signal detected by the geomagnetic sensor 112 and the size of the LCD screen. . Referring to FIG. 5, an image signal is received and the size of the screen of the mobile terminal is detected (S41 and S42). Subsequently, after detecting the geomagnetic signal by the geomagnetic sensor 112, the direction of the screen is determined (S43, S44). If the determination result screen is a horizontal screen, the received video signal is resized to fit the horizontal screen of the terminal LCD. If the determination result screen is a vertical screen, the received video signal is resized to the vertical screen of the terminal LCD (S45 ~ S48).

Referring back to FIG. 4, when a call (CALL) or a text message (SMS) is received from the counterpart while viewing the broadcast screen, the calling number is displayed as a subtitle on the broadcast screen (S5, S6).

Accordingly, when the user sees the subtitle displayed on the screen and wants to answer the call, the user presses the call key to make a normal call, and if the user does not want to call, the broadcast is continued (S7 to S9).

If the user changes the channel while watching a broadcast, the user accesses the selected broadcast channel and repeats the broadcast receiving process (S10).

As described above, according to the present invention, an existing wireless network and an existing Internet broadcast (for Pocket) service can be used to watch TV broadcasts or radio broadcasts in a general phone instead of a DMB terminal. Particularly, according to the present invention, the mobile terminal has a broadcasting viewer and a remote control function, and the screen is automatically converted to fit horizontally and vertically when the screen is viewed horizontally using the geomagnetic sensor 112. Resizing is made according to the size of the user's terminal LCD. The present invention is suitable for a terminal having a LCD size of QVGA, especially among the existing older terminals, and adopts a data flat rate plan, so that users can listen or receive broadcasts with 1X and EVDO without burden. In the case of 1X, the existing network can be connected at 16x ~ 8x speed.

As described above, according to the present invention, the broadcast receiving VM is downloaded to a mobile terminal (mobile phone), and thus, a general mobile phone can receive a TV or radio broadcast like a DMB phone.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the present invention without departing from the spirit and scope of the invention described in the claims below. I can understand that you can.
