The update information includes software version information and at least one of terminal manufacturer information and terminal model information. Further, the method may further include, before broadcasting the created update command, forcibly requiring terminals subscribe to an update service; and creating and broadcasting an update file for terminals of the particular model from among the forcibly subscribed terminals. The software of the terminals may be firmware. | 10-01-2009 |
| 20090249403 | APPARATUS AND METHOD FOR PROVIDING CONTENTS IN INTERNET BROADCASTING SYSTEM - An Internet broadcasting system for supporting broadcast services by using Internet Protocol (IP), and more particularly an apparatus and method for providing a user's preferred contents in an Internet broadcasting system are provided. The method of providing contents in an Internet broadcasting system includes searching for contents in an Electronic Program Guide (EPG) according to a user preference, constituting a user channel, based on the searched contents and providing a terminal with the searched contents according to the user channel. | 10-01-2009 |
| 20090253416 | METHOD AND SYSTEM FOR PROVIDING USER DEFINED BUNDLE IN A MOBILE BROADCAST SYSTEM - A method and mobile communication system for providing a user defined bundle in a terminal of a mobile broadcast system are provided. The method includes receiving a service guide from a BroadCAST (BCAST) Service Distribution/Adaptation (BSDA), creating a user defined bundle based on a content or a service desired by a user, including the user defined bundle in a user defined bundle subscription request message and transmitting the user defined bundle subscription request message to a BCAST Subscription Management (BSM), and receiving from the BSM a user defined bundle subscription response message in which a user defined bundle subscription and a purchase complete message is included. | 10-08-2009 |
| 20090254481 | METHOD AND APPARATUS FOR PROVIDING PERSONALIZED SERVICE IN BROADCASTING SYSTEM AND SYSTEM THEREOF - A method and apparatus for providing a personalized service in a broadcasting system, and a system thereof. A BCAST Subscription Management (BSM) sends a service creation request message to a BCAST Service Distribution/Adaptation (BSDA), the service creation request message including at least one purchase data fragment to which maximum allowed content and maximum allowed service elements are added. The BSDA creates a service guide using the purchase data fragments, and delivers it to a terminal. The terminal checks a service type in the service guide, sends a subscription request for the personalized service to the BSM, receives an encryption key associated with the personalized service, and receives the personalized service with the encryption key. | 10-08-2009 |
| 20090265700 | METHOD AND SYSTEM FOR UPDATING FIRMWARE OF TERMINALS IN A BROADCAST SYSTEM - A method and apparatus for updating firmware of terminals in a mobile broadcast system including a Broadcast Service Distribution/Adaptation fragment (BSDA) and a Broadcast service Subscription Management (BSM). The method includes requesting creation of a content fragment, by the BSM, by transmitting a firmware package file for a firmware update of the terminals to the BSDA; creating a content fragment including the firmware package file and broadcasting the created content fragment to the terminals by the BSDA; detecting the firmware package file from the received content fragment; and performing the firmware update using the firmware package file. | 10-22-2009 |
| 20090271837 | APPARATUS AND METHOD FOR PROVIDING BROADCAST CONTENTS IN INTERNET BROADCAST SYSTEM - A method and apparatus for providing content in a broadcast system is provided. Upon receipt of a request for synchronization from a mobile terminal, a set-top box creates a recommended content list based on user information received from the mobile terminal and delivers the recommended content list to the mobile terminal. The set-top box receives from the mobile terminal a content list, selected from the recommended content list and included in a Personal Information Management System (PIMS) updated using the recommended content list. The set-top box determines whether a user of the mobile terminal intends to view content from the received content list at a start time of the content. Upon receipt of view acceptance information from the mobile terminal, the set-top box sends a request for the content to a service provider at the start time, receives the requested content from the service provider, and provides the received content to the mobile terminal. | 10-29-2009 |
| 20090276818 | METHOD FOR PROVIDING IPTV SERVICE AND INTERNET BROADCASTING SYSTEM THEREFOR - An apparatus and method for providing preferred contents to a user in an Internet broadcasting system that provides a broadcast service using an Internet data transport protocol. A user terminal sends a request for a broadcast service to a service provider. The user terminal receives an authentication key from the service provider, and delivers the authentication key to a third display terminal in which a user of the user terminal is not registered. The third display terminal delivers the authentication key and connection information of the third display terminal to the service provider. The service provider authenticates the third display terminal. The user terminal transmits information selected by the user to the service provider, which transmits broadcast service data related to the selected information to the third display terminal for being displayed. | 11-05-2009 |
| 20100138872 | SERVICE GUIDE TRANSMISSION/RECEPTION METHOD AND APPARATUS FOR BROADCAST SERVICE - Service guide transmission/reception methods and apparatuses for providing users with a service guide supporting multiplay service are provided. Service guide delivery information is received at a terminal. Device class grouping information is extracted from the Service guide delivery information. A Service Guide Data Unit (SGDU) having service guide information required for composing a service guide matched to the terminal is received. The service guide composed using the service guide information received by means of the SGDU is displayed. | 06-03-2010 |
| 20100159912 | REMOTE MANAGEMENT METHOD AND SYSTEM FOR WIRELESSS COMMUNICATION TERMINAL - A remote management method for a terminal supporting a mobile broadcast service is provided. The terminal receives a service guide with a terminal function management condition from a mobile broadcast service broadcasting server, stores and processes the service guide, and delivers a service subscription request to the mobile broadcast service broadcasting server, receives a message with a Device Management (DM) command generated by a DM server, as the mobile broadcast service broadcasting server receiving the service subscription request sends a request for a DM command regarding a function and a management operation of a terminal to be managed, to the DM server, and stores the DM command and executes the DM command if a status of the terminal satisfies the terminal function management condition. | 06-24-2010 |
| 20100180310 | RICH MEDIA-ENABLED SERVICE GUIDE PROVISION METHOD AND SYSTEM FOR BROADCAST SERVICE - A service guide provision method and system for a digital broadcast service is provided for distributing a rich media-enabled service guide. A rich media-enabled service guide provisioning method for a digital broadcast service includes creating a Rich Media Solution (RMS) template for a service guide with reference to service guide fragments; creating a service guide delivery descriptor containing RMS information on the RMS template and service guide fragment information on the service guide fragments; and broadcasting the service guide fragments, the RMS template, and the service guide delivery descriptor. | 07-15-2010 |
