摘要:
Disclosed is a system and a method for offering a digital video broadcasting service, and for offering multiple sub-services connected with a main service simultaneously with the main service while offering a DVB-H service. The system includes a digital broadcasting station for adding SubScheduleID fields, in which information on at least one sub-service connected with a main service can be respectively stored, to a service information fragment offering information on services, for setting schedule IDentification (ID) values included in a fragment of the sub-service to SubScheduleID values of the SubScheduleID fields, for generating a fragment of the information on the sub-services, for including the generated fragment of the information on the sub-services in Electronic Service Guide (ESG) data, and for transmitting the ESG data; and a digital broadcasting receiving terminal for receiving the ESG data, for checking information on at least one sub-service connected with a selected main service through the fragment of the information on the sub-services if the main service is selected, and for displaying the checked sub-services simultaneously with the main service.

Disclosed is a method and a system for broadcasting an Electronic Service Guide (ESG) for digital broadcasting, which includes predetermined change information, when important information of the ESG is changed in a digital video broadcasting system. A digital broadcasting apparatus broadcasts an ESG that includes current information data and predetermined change information through a broadcasting communication network. A digital broadcasting reception terminal receives and stores the broadcasted ESG, provides a digital broadcast service based on the current information data of the ESG and provides a digital broadcast service based on the stored predetermined change information data after a prescheduled ESG change time point.

Disclosed is a system and a method for providing a terminal with a notification message reporting changes of a system and of a service in the middle of a Digital Video Broadcasting-Handheld (DVB-H) broadcasting service. The system inserts channel information related to the transmission of the notification message into Electronic Service Guide (ESG) service fragment or ESG acquisition fragment, then transmits the inserted channel information, or specifies a notification session for a session to transmit the session. In this manner, the channel information related to the notification message can be transmitted to a terminal through an ESG, and the terminal acquires the channel information related to the notification message from the received ESG to receive the notification message by using the channel information.

A method and apparatus perform channel scanning in a wireless communication system. A signal intensity of an Access Point (AP) is compared with a scanning threshold, when the AP signal intensity not less than the scanning threshold, a channel scanning schedule list is generated in consideration of a scan time based on a passive channel scan scheme and a scan time based on an active channel scan scheme. The channel scanning is performed every channel scanning time, according to the channel scanning schedule list.
摘要:
An apparatus and method provide effective video transmission in a communication system that supports an Internet Protocol Television (IPTV) service between heterogeneous networks. A request for a contiguous service is received from a terminal during a mid-point of a video stream. A delay time that may be generated when the video contents are transmitted is estimated for each of a patching type and a fast broadcasting type. A transmission type with a shorter delay time for the video contents is determined based on the estimated delay time for each of the patching type and the fast broadcasting type. And the video contents are transmitted to the terminal by applying the determined transmission type.

Disclosed is a system and method for efficiently providing Electric Service Guide (ESG) data in a Digital Video Broadcasting-Handheld (DVB-H) system. There is presented a method for dividing ESG data into basic data and additional data and for separately providing the data, wherein the basic data is necessary to provide a DVB-H broadcasting service. To separately provide the basic data from the additional data, a service provider forwards, during a basic profile session, only the basic data necessary to provide a broadcasting service, and separately forwards additional data during an advanced profile session including additional and high-grade data. Then, a terminal determines if a profiling is set up. If the profiling is set up, the terminal gets access to the basic profile session to acquire the basic data, and deals with the advanced profile session as a background job. As a result, the terminal first gets the basic ESG data necessary to provide the broadcasting service, which can antedate the commencement of the broadcasting service, and which can improve the effectiveness of a data receiving scheme of the terminal in great measure.

摘要:
Disclosed is a method and a digital broadcasting system for transmitting and receiving an Electronic Service Guide (ESG). When there are ESG fragments to be transmitted through a communication network among ESG fragments included in ESG data, a digital broadcast transmitter generates an ESG data session such that the ESG data session may include route information through the communication network of the relevant ESG fragments. Then, the digital broadcast transmitter transmits the generated ESG data session to a broadcast receiving terminal, which obtains the route information through the communication network of the relevant ESG fragments. Accordingly, a user can more easily and conveniently receive the ESG data by using the route information through the communication network obtained by the broadcast receiving terminal.

An apparatus and method for automatically registering and executing a preferred function in a mobile communication terminal. The method includes registering a function and a configuration value and use character string/numeral string value for the function, to a one-touch execution object. The method also includes, when a one-touch input for the one-touch execution object is sensed, executing the function registered to the one-touch execution object, by the configuration value and use character string/numeral string value registered to the one-touch execution object.
