Abstract: A method for identifying traffic information includes receiving traffic data including a first identifier, an amount of time currently taken to traverse a particular link, and information corresponding to a location associated with the particular link. The first identifier enables a determination of a type of the information that is included within the received traffic data. The method also includes determining a type of information included within the received traffic data based on the first identifier and determining current travel time information based on the information included in the received traffic data only if the first identifier enables a determination that the received traffic data includes an amount of time.

Abstract: A method for identifying traffic information includes receiving traffic data including a first identifier, information corresponding to a prediction of an amount of congestion for a particular link, and information corresponding to a location associated with the particular link. The first identifier enables a determination of a type of the information that is included within the received traffic data. The method also includes determining a type of information included within the received traffic data based on the first identifier and determining congestion amount prediction information based on the information included in the received traffic data only if the first identifier enables a determination that the received traffic data includes a prediction related to congestion amount.

Abstract: A method for identifying traffic information includes receiving traffic data including a first identifier, information corresponding to a predicted amount of time to traverse a particular link, and information corresponding to a location associated with the particular link, where the first identifier enables a determination of a type of the information that is included within the received traffic data. The method also includes determining a type of information included within the received traffic data based on the first identifier and determining travel time prediction information based on the predicted amount of time included in the received traffic data only if the first identifier enables a determination that the received traffic data includes a prediction related to an amount of time.

Abstract: A method of processing traffic information includes receiving link vertex information including a first identifier and vertex components that each reveal a position along a link. The first identifier enables a determination of a type of information that is included within the received link vertex information. The method also includes determining the type of information included within the received link vertex information based on the first identifier and identifying vertex components within the link vertex information only if the first identifier enables a determination that the received link vertex information includes at least one vertex component.

Abstract: A method for identifying traffic information for at least one sub-link includes receiving traffic information including a sub-link identifier enabling a determination of whether the received traffic information includes sub-link information, traffic status information enabling a determination of traffic information for a sub-link, information identifying a link within which the sub-link is located, and sub-link location information enabling a determination of a portion of the link that corresponds to the sub-link. The method also includes determining, based on the sub-link identifier whether the received traffic information includes sub-link information and dependent on whether the sub-link identifier enables a determination that the received traffic information includes sub-link information.

Abstract: A method for transmitting location information includes the steps of: a) receiving a start message including MO (mobile originated location request) mode information from a first terminal; b) calculating location information of the first terminal; and c) transmitting the calculated first terminal's location information according to the MO (mobile originated location request) mode information. A method for transmitting location information in a Secure User Plane Location (SUPL) protocol of a first SUPL Enabled Terminal (SET), a SUPL Location Platform (SLP), and a second SUPL Enabled Terminal (SET) includes the steps of: a) receiving a start message including MO (mobile originated location request) mode information from the first SET; b) calculating location information of the first SET; and c) transmitting the calculated first SET's location information to any one of the first SET and the second SET according to the MO (mobile originated location request) mode information.

Abstract: An apparatus and a method for controlling an electric appliance using a broadcast wave are disclosed. Various electric appliances widely used in each household are so configured as to be equipped with a broadcast receiving module and receive a product-related additional data packet through the broadcast wave such as an FM multiplex broadcasting. The electric appliance controls its own operation according to information in the received additional data packet. Accordingly, the present invention enables the electric appliances to be remotely controlled by receiving the product control information packet transmitted through the broadcast wave. The present invention enables a natural disaster to be warned by receiving a disaster warning data packet transmitted through the broadcast wave. The present invention further enables guidance information on the electric appliance to be displayed by receiving the product guidance information packet transmitted through the broadcast wave.

Abstract: In the present invention, traffic information broadcast by a traffic information center is received, indexes are created, and the index and travel speed information on a mobile object are stored. A matching table is created to match first map data for use in broadcasting the traffic information and second map data used by a navigation system to each other. The traffic information is simply matched to the second map data used by the navigation system, using the created matching table. When the travel speed of the mobile object on each link is intended to be displayed with a predetermined color after the matching of the traffic information to the second map data, the storage capacity of a traffic information storage unit is reduced, which stores traffic information displayed together with arrows for indicating the travel direction.

Abstract: When a vehicle location is estimated using only detection signals from a sensor unit installed on a vehicle since the value of dilution of precision (DOP) of a navigation message received by a GPS receiver is equal to or greater than a predetermined threshold in a navigation system, the vehicle location is precisely estimated using a traveled distance, a travel angle difference, and lateral and longitudinal inclinations of the vehicle. The value of DOP of the navigation message received by the GPS receiver is compared with the predetermined threshold. If the value of DOP is less than the predetermined threshold, reference vehicle location information is set using the navigation message. If the value of DOP is equal to or greater than the predetermined threshold, the reference vehicle location information is set using vehicle location information just previously map-matched and the detection signals from the sensor unit.

Abstract: A clipping plane is formed between a projection center position and a projection plane such that the clipping plane is parallel to the projection plane. A three-dimensional line is subjected to clipping at the clipping plane. It is determined whether respective nodes constituting a three-dimensional line in a three-dimensional image to be projected onto the projection plane exist inside or outside a view volume, by comparing z-axis values of the nodes with a z-axis value of the clipping plane with respect to the projection center position. If the nodes of the three-dimensional line exist both inside and outside the view volume, a new three-dimensional line is constructed using nodes existing inside the view volume and intersections between the current three-dimensional line and the clipping plane, or using only the nodes existing inside the view volume.
