Disclosed herein is a method and apparatus for providing traffic information of public transportation means, such as a bus, and utilizing the provided information. A method of encoding public traffic information according to the present invention creates, for an arbitrary bus stop, a first component including the number of buses to arrive at the bus stop and as many pieces of bus information as the created number of buses, and incorporates the first component along with an identifier allocated to the bus stop into a second component. The second component is then incorporated into a transfer message. A sequence of messages, each being constructed as described above, is wirelessly transmitted.

Method and apparatus for providng and using public transportation information

A digital broadcasting system and a data processing method are disclosed. A receiving system of the digital broadcast system includes a mobile service data processor, a main service data processor, a controller, and a display module. The mobile service data processor receives mobile service data through a mobile service data path. Herein, the mobile service data configures an RS frame, and the RS frame includes mobile service data including a mobile A/V broadcast signal and at least one channel configuration information on the mobile service data. The main service data processor receives main service data through a main service data path. Herein, the main service data includes a main A/V broadcast signal and a program guide information of the main A/V broadcast. The controller extracts a link information for the program guide service of the mobile A/V broadcast signal from the channel configuration information, and acquires a corresponding program guide information from the main service data processor by using the extracted link information. And, the display module outputs the program guide information acquired from the controller to a display screen.

Disclosed herein is a method and apparatus for providing traffic information of public transportation means, such as a bus, and utilizing the provided information. A method of encoding public traffic information according to the present invention creates an identifier of bus information system, an ID of bus route, and travel time on each section wherein the section is link between neighboring two stops among bus stops pertaining to the bus route. The created information is organized to status information that is in turn incorporated into a transfer message. A sequence of transfer messages, each being constructed as described above, is wirelessly transmitted.

A method for protecting disc copy of the present invention includes the steps of detecting an identifier of a disc to be reproduced and determining if a disc copy is permitted or not using copy protection disc information and the identifier. A recording and reproducing apparatus having a disc copy-protection function of the present invention includes a reproducing drive for reading data from a disc, a recording drive for writing data on other disc, storage unit for storing a copy-protection disc information for judging whether a disc copy is permitted or not, and control unit for controlling a disc copy from the disc in the reproducing drive to the other disc in the recording drive.

Recording and reproducing apparatus having copy-protection function and method thereof

There is provided a method of recording and reproducing an optical recording medium which performs a tracking servo and a focusing servo by irradiating a laser beam onto determined positions including lands and grooves of a track of the recording medium and detecting a tracking error signal and a focusing error signal using an electric signal from an optical pickup for picking up the laser beam reflected from the recording medium. The method includes the steps of: detecting servo information in a plurality of the determined positions including lands and grooves of the track while rotating the recording medium in a state in which only the focus servo is turned on when the optical recording medium is loaded, storing the servo information of the respective determined positions as a table, and performing the servo of the corresponding positions by applying the servo information in table during an actual data recording/reproduction.

Method of recording and reproducing an optical recording medium

The present invention relates to a method of providing and utilizing information for vehicle travel, such as information about traffic flow on roads, and about parking lots. In an encoding method according to the present invention, at least one component including information for vehicle travel is generated. Information about a time point is included in the generated component. The information about the time point includes a selector, having a bit element indicating whether to use the present date and time and indicating the type of loaded information, and at least one of information elements indicating a year, month, day, hour, minute, and second, depending on the value of the selector.

Method of providing and utilizing information for vehicle travel

A digital broadcasting system and a data processing method are disclosed. The receiving system of the digital broadcasting system includes a receiving unit, a main service data processor, a mobile service data processor, a controller, and an output controller. The receiving unit receives mobile service data and main service data including the same A/V broadcast signal and receives retransmission channel information. The main service data processor demodulates and error-corrects the received main service data and temporarily stores the processed data. The mobile service data processor demodulates and error-corrects the received mobile service data and temporarily stores the processed data. The controller generates and outputs a control signal based upon the received retransmission channel information and a receiving environment of the receiving system. And, the output controller selects any one of the A/V broadcast signal for the main service and the A/V broadcast signal for the mobile service based upon the control signal of the controller.

Disclosed is a method and apparatus for controlling the record and reproduction of optical record medium in which plural nonrecord regions having different phase are arranged between recordable data regions for the distinction in the shape of the data region. The method and apparatus performs the servo using focus error signal and tracking error signal averaged by the low pass filter at the header region of the optical disc. Especially, the tracking servo is performed by holding a fixed DC off-set value at the header region existing on the L/G switching or holding the tracking error value of the previous same track region. As a result, the exact header region is detected, the track sliding phenomenon is removed, and the tracking servo is stabilized, resulting in preventing the degeneration of the record and reproduction characteristics.
