摘要:
A method of upgrading software through a software download in a T-DMB terminal includes the steps of confirming, by the T-DMB terminal, an announcement message containing information for announcing when the software is downloaded by receiving a T-DMB signal and analyzing a plurality of fast information groups (FIGs), determining whether the software is downloaded according to information contained in the announcement message, if it is determined that the software is downloaded, storing ensemble information and download start time information among the information contained in the announcement message; matching a current ensemble with the stored ensemble when time according to the download start time information elapses, and confirming a signaling message for informing that the software is downloaded by analyzing an FIG received through the matched ensemble, and downloading the software.

Disclosed is a broadcasting system and method for transmitting/receiving a broadcast data in a broadcasting system, which reduces an application download period by efficiently utilizing a data broadcasting stream and a return channel for application download when a reception terminal receives a data broadcast. The broadcasting system and method includes a data broadcast reception terminal to receive the broadcast data and a bi-directional broadcasting server to communicate with the data broadcast reception terminal through a return channel: the data broadcast reception terminal receives a data broadcast stream during one broadcast transmission period, and requests the bi-directional broadcasting server to transmit a portion of the data broadcast stream (e.g. section data) through the return channel when the section data of the received data broadcast stream is lost; the bi-directional broadcasting server transmits the section data to the data broadcast reception terminal when a download request is received for the section data from the data broadcast reception terminal; and the data broadcast reception terminal performs modularization using a received lost section data and the previously-received section data to extract application files when receiving the lost section data and displays the extracted application files on a screen.

Disclosed is a method for providing multiple formats through an XML based EPG schema in terrestrial DMB system. The method includes the steps of setting a predetermined type in an area for defining type information of the EPG information, setting the defined predetermined type to have at least one format value, and making a definition to convert a format type to the defined predetermined type in an XML schema for expressing the EPG service information.
摘要:
Disclosed are a digital broadcasting system and a method for transmitting and receiving electronic service guide data in a digital broadcasting system, which communicates applications capable of executing content files downloaded through a file download service. The digital broadcasting system includes a digital broadcasting transmitter for broadcasting Electronic Service Guide (ESG) data which includes application information corresponding to respective content files, and a digital broadcasting receiver for receiving the broadcasted ESG data and executing applications corresponding to the respective content files by using the application information included in the ESG data.
摘要:
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.
摘要:
A preset recording method through service linking according to movement from a first broadcasting area to a second broadcasting area in a terrestrial DMB terminal is provided. A preset recording for a predetermined broadcast program is checked to see if a current time is equal to a recording start time based on the specified preset recording; if so, extracting service linking information for the predetermined broadcast program; displaying that the DMB terminal has moved from the first broadcasting service area for the preset recording when the extracted service linking information corresponds to hard linking information, and recording a broadcasting program according to the hard linking information; and if they correspond, displaying that the DMB terminal has moved from the first broadcasting service area for the preset recording, and providing a list of broadcasting programs according to the soft linking information to enable a user to reset a preset recording function.

摘要:
Disclosed is a method for providing a similar broadcasting service in a DVB-H system. The method includes: configuring and broadcasting Electric Service Guide (ESG) data including service linking information in which a DVB-H transmission server including data and access information about at least one linked service set in a certain DVB-H service; and receiving and storing the ESG data by a DVB-H reception terminal, detecting service linking information corresponding to a DVB-H service during reception from the ESG data if a reception intensity of signals is less than a preset reference value during reception of the DVB-H service, stopping reception of the DVB-H service being currently received, and receiving a linked service included in the service linking information with reference to the detected service linking information.
摘要:
Disclosed is a method for indicating whether to provide supplementary services through EPG information in a terrestrial DMB system. In this method, a DMB terminal of the terrestrial DMB system receives DMB broadcast data, and extracts the EPG information from the DMB broadcast data. The extracted EPG information is sorted according to service formats of an XML schema for providing the EPG information. Supplementary service information relating to a corresponding program is extracted from the sorted EPG information by means of a program format of the XML schema, and the extracted supplementary service information is stored together with the EPG information. The supplementary service information is provided together with program information of the corresponding program when the EPG information is displayed.
