The TPEG message includes a message management container and a road traffic message event container. (RTM Event Container) and TPEG Location Container.

Also, in the road traffic message event container, accident information including position information such as 'entry slip road' and vehicle information is included as an event description element. In addition, the 'accident' message, which is already defined in the TPEG message, is recorded and recorded. The vehicle information includes, for example, a position indicating that the accident location is a driving lane 2. And vehicle problem information indicating that the vehicle is an overturned accident, and vehicle info indicating that the vehicle is a car.

Incident-related situation information corresponding to the 'Accident' message is recorded together as a multimedia descriptor in the road traffic message event container, and in the TIP location container, default language code information and location One or more of Location Coordinates information and Additional Location Descriptions information is recorded. The default language code is, for example, a unique code value indicating that the language is Korean. Can be recorded,

The location coordinate information may include location type information indicating a small area, mode type list information indicating 'road', latitude and longitude coordinate values, For example, latitude and longitude coordinate values of WGS 84 (World Geodetic System 1984) can be recorded.

In addition, as shown in FIG. 21, the 'Accident' message includes position information indicating an accident location, animal information related to an accident, vehicle information, and people information. In addition, the multimedia descriptor includes, as shown in FIG. 22, any one or more of an image, text, audio, and video is recorded. As illustrated in FIG. 20, an image of an accident-related situation is included. Image data, text data, and audio data may be recorded.

Meanwhile, the accident related situation information may be provided as a video in a news form, and the incident related situation information may be provided as described above with reference to FIG. 18 and includes a modulator 70, a TPEG encoder 71, and an addition. The encoding device composed of the information generating unit 72, the storage 73, the navigation engine 74, the input device 75, the memory 76, and the like is included and transmitted in the encoded T-pack message.

For example, various accident-related situation information, which is additional information received through the input device 75 or corresponding to road event information pre-stored in the storage 73, may be used to control the operation of the navigation engine 74. Accordingly, the additional information generating unit 72 is input.

In addition, the additional information generation unit 72 converts the accident-related situation information into at least one of an image, audio, video, and text of a multimedia descriptor, and generates a message segment to generate a message segment. In the encoder 71, the accident-related situation information data of the generated message segment is recorded and included as a multimedia descriptor in the road traffic message event container in the TPEG message sequence.

In addition, the modulator 70 modulates the TPEG message including the multimedia descriptor as described above, and outputs the TPEG message together with the DMB broadcast. The DMB terminal receives the same, for example, in the DMB terminal. As described above with reference to FIG. 19, the tuner 80, the demodulator 81, the TPEG decoder 82, the GPS module 83, the navigation engine 84, the input device 85, the storage 86, The memory 87, the LCD drive 88, the LCD panel 89, and the like may be included.

Meanwhile, the GPS module 83 may be replaced with a CDMA module, and the DMB broadcast signal received through the tuner 80 is demodulated by the demodulator 81 and then the TPEG decoder 82. Decoded by the navigation engine 84 interprets the TPEG message decoded by the TPEG decoder 82 to extract components within the segment.

After retrieving road event information from the extracted component, the event related situation information corresponding to the road event information is extracted, stored in the storage, and displayed on the LCD drive 88.

On the other hand, for example, as shown in FIG. 23, when the user selects 'view map traffic information' from various menu items provided by the DMB terminal to display a traffic map screen, the navigation The engine 84 searches for the RTM event container included in the TPEG message.

When the accident-related situation information is searched for in the RTM event container, for example, as shown in FIG. 23, a mark and a number such as 'under construction' or 'accident' may be displayed on the accident occurrence area. After that, when the user selects No. 1 corresponding to 'under construction', as shown in FIG. 23, the information related to the accident-related situation found in the TPEG message is decoded to display an image together with the message 'under construction of the road along the riverside.' Will be displayed on the screen.

In addition, when the user selects No. 2 corresponding to 'accident', as shown in FIG. 23, the information related to the accident-related situation retrieved from the TPEG message is decoded to display an image together with the message of 'Hannam Bridge entrance rollover accident'. In the screen display, the accident-related situation information may be displayed as an image and text of a still image or a video in a news form.

Accordingly, the user carrying the DMB terminal can easily check the accident-related situation information through the image and text of the still image or the video of the news form.
