In addition, when the user requests the detour road guidance, the traffic condition deterioration section is checked for the shortest path between the starting point and the destination, and a candidate path is set based on the distance that bypasses the deterioration section, and a path profile is generated. The route profile is transmitted to the IP broadcast content server 123 for searching route contents.

The receiver 420 receives the corresponding route contents searched by the IP broadcasting content server 123 and the contents metadata based on the route profile. At this time, the IP broadcast control server 122 recognizes that the traffic information content received from the specific information provider (for example, the real-time traffic information monitoring camera) exists in the specific section on the corresponding route. In addition, when the user requests a detour road guidance service, corresponding content and metadata are received from the IP broadcast content server 121 for each candidate path set.

The content combination unit 430 combines the received content by the content provider to form mega content and generate a mega content profile. The content constituting the mega content profile may include real-time traffic information image content, video content having a validity in time, traffic information photo content collected from a personal portable camera, and traffic information short message content.

The content reconstruction unit 440 analyzes and grasps the contents and metadata included in the mega content profile to recognize the traffic situation on the route and adds the recognition metadata to the mega content profile. For example, the metadata generator 445 determines the level of smoothness, delay, congestion, etc. by identifying the number of vehicles per one lane unit area and the actual vehicle speed compared to the road network speed limit for a frame of the video. Generating recognition metadata representing the information is inserted into the mega content profile.

The virtual channel setting unit 450 configures a virtual channel to broadcast the mega contents to the user navigation terminal as one channel, and requests the content-based session control server 123 for session and media path setting for each content.

Charges and benefits are made. Hereinafter, a process of uploading content and providing content will be described in detail.

6 is a flowchart illustrating a process of uploading traffic information content from a content provider to an IP broadcast content device according to an embodiment of the present invention.

The content provider that attempts to upload the traffic information content collected by the IP broadcast content server 121 first attempts to access the content server (S610).

Uploading the traffic information content to the content server is different depending on whether or not the content provider is mobile.

First, if the content provider has mobility, it collects its own location and movement speed information (631). In this case, the content providing unit collects the moving speed information of the vehicle from the vehicle tachometer if the camera is mounted on the vehicle, and collects the location information and the moving speed information from the base station if the camera is carried by the individual. Next, the content provider collects surrounding camera image information (632). Next, the traffic information content composed of the video and the location and the speed information is uploaded (S633).

The IP broadcast content server 121 segments the traffic information content received in real time by a predetermined time unit (S634). In operation 650, metadata, such as a provider, a location, a vehicle speed, a time, a content type, and a feature, is generated and added in units of segmented traffic information content, and the content is stored (650). The stored content is checked for validity at regular intervals, and the traffic information content whose validity is lost is deleted (S660).

If the content providing unit is not mobile, the location information given at the time of installation is collected (641), the speed of the vehicle passing through a specific area per unit time is sensed to collect the vehicle speed of the corresponding section (642), and from the camera The video information is collected (643). Next, the traffic information content configured with the unique location information and the vehicle speed information by sensing is uploaded (644).

The IP broadcasting content server 121 adds 645 metadata, such as a provider, a location, a vehicle speed, a time, a content type, and a feature, to the received traffic situation content and stores the traffic situation content 650. The stored content is checked for validity at regular intervals, and the traffic information content whose validity is lost is deleted (S660).

7 is a flowchart illustrating a traffic information navigation process in the IP broadcast control device according to an embodiment of the present invention.

A user inputs a route to a departure point and a destination using a user navigation terminal, and the user navigation terminal transmits route information set by the user to the IP broadcast control server.

The IP broadcast control server 122 registers the received destination route information of the user, and generates a route profile according to the route (S710).

The generated route profile is transmitted to the IP broadcast content server 121, and the IP broadcast content server 121 searches for the content and content metadata of the corresponding route based on the route profile and metadata in the stored traffic information content. .

The IP broadcast control server 122 receives the corresponding route content and the content metadata transmitted and searched (S720). In this step, the IP broadcast control server 122 finds that the traffic information content received from the specific traffic information provider is present in the specific section on the route to the destination.

Next, a mega content profile is generated by combining the traffic information contents generated from the individual content providing units (S730). When generating the mega content profile, it is preferable to configure the mega content profile using the high priority content when duplicate content exists for a specific section.

The IP broadcast control server 122 configures a mega content virtual channel to broadcast the mega content profile to the user navigation terminal as one channel, and delivers the mega content profile information to the content-based session control server 123 to the destination of the user. A session setup and a media path setup for the contents retrieved on the path are requested (S740). The content-based session control server 123 sets up a session for connecting the user to the contents identified from the mega content profile and sets a media path for delivering the actual content.

The IP broadcast control server 122 recognizes a traffic condition for each section by using the traffic information content and metadata information on the route, generates recognition metadata, and inserts the recognition metadata into the mega content profile (S750). In order to display the mega content profile on the user terminal, the user GUI is configured and transmitted to the user terminal.

When the user requests a specific section detail view, the IP broadcast control server 122 controls the corresponding section content to be broadcasted from the IP broadcast content server 121 to the user navigation terminal.

The update of the traffic condition information is performed periodically, and the traffic condition fluctuation of a specific section is notified to the user by adding traffic condition awareness metadata. Termination of the service is terminated by the user's termination request.

Therefore, the mega content profile according to the initial route setting may be updated and provided to the user by re-requesting traffic state information of the user and a specific event (accident, etc.) on the route.

8 is a flowchart illustrating a detour road guide service process in an IP broadcast control apparatus according to an embodiment of the present invention.

Referring to FIG. 8, when a user requests a detailed view of content on a traffic condition of a specific section, the user navigation terminal displays the corresponding content.

If the user requests the detour road setting due to the deteriorating traffic condition, the IP broadcast control server 122 checks the deteriorating traffic condition section on the current destination route (shortest distance) (S810).

A candidate path is set for a bypass road compared to a distance bypassing a worsening traffic situation, requests the IP broadcast content server 121 to provide content for the candidate path, and receives the found candidate path content and corresponding metadata (S820). ).

Next, the moving speed of the vehicle relative to the speed limit is calculated for the detour road candidate path, and the cumulative speed ratio to the destination of each detour road is calculated (S830). The cumulative speed ratio can be converted into the cost or time spent using the route.

The IP broadcast control server 122 selects an optimal detour road in response to a detour road setting request from the user terminal, sets a detour road, and provides the content information to the user navigation terminal (S840).

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.
