Abstract: Disclosed is a method of providing additional content in a digital broadcast reception apparatus, the method including receiving a locator of additional content from a broadcast server while a user watches a broadcast program, receiving an instruction to insert the additional content from the broadcast server, receiving and reproducing the additional content from a content providing server designated by the locator, and switching back to the broadcast program. Thus, it is not necessary to allocate a separate channel and/or to switch channels for providing additional content.

Abstract: Provided are a method and a device for booting a host embodying a downloadable conditional access system (DCAS), wherein one of a plurality of pre-determined booting modes is decided as a booting mode of the host based on first information indicating whether a host can communicate with a broadcasting service provider and second information indicating whether a software-based security client providing information required for decrypting broadcasting data is installed to a hardware-based security module connected to the host, and the host is booted in the decided booting mode.

Abstract: A plurality of conditional access (CA) clients are needed to receive services from a plurality of service, where the CA clients respectively correspond to the service providers. Thus, the CA clients should be installed into a broadcast receiver, and in this case, a method of managing the CA clients is needed. Provided are a method and apparatus for processing broadcast data by using a security client. The method includes determining a first security client based on a security client list, where the first security client is used to decrypt encrypted broadcast data and the security client list comprises information regarding each of security clients available which provide information necessary to decrypt the encrypted broadcast data; and decrypting the encrypted broadcast data by using the first security client. Accordingly, it is possible to allow a user to receive various services.

Abstract: A method of communicating with a host in a security module providing information necessary for decrypting encrypted broadcast data received by the host, includes if an event occurs, characterizing the event as an event that a user of the host is to be notified about with regard to the decryption of the encrypted broadcast data, generating a user notification message including information about the event that occurred; and transmitting the user notification message to the host.

Abstract: A method and apparatus for efficiently selecting a demodulation scheme for a particular channel in a digital broadcast receiver supporting a plurality of demodulation schemes are provided. The method includes receiving the digital broadcast signal of the channel; attempting demodulation of the digital broadcast signal using a demodulation scheme corresponding to a sequential index; and if the demodulation attempt succeeds, restoring data and if the demodulation attempt does not succeed, attempting demodulation again using a demodulation scheme corresponding to a next sequential index.

Abstract: A method is used by an Open Cable-Digital Media Player (OC-DMP) to process a request of an application with respect to content of an Open Cable-Digital Media Server (OC-DMS). The method includes determining validity of the request based on metadata of the content, and selectively transmitting the request to the OC-DMS based on a result of the determination.

Abstract: Disclosed is a method of providing additional content in a digital broadcast reception apparatus, the method including receiving a locator of additional content from a broadcast server while a user watches a broadcast program, receiving an instruction to insert the additional content from the broadcast server, receiving and reproducing the additional content from a content providing server designated by the locator, and switching back to the broadcast program. Thus, it is not necessary to allocate a separate channel and/or to switch channels for providing additional content.

Abstract: An apparatus and method for communication between an embedded cable modem and an embedded set-top box in a DOCSIS Set-top Gateway (DSG)-based digital broadcast receiving apparatus are provided. The apparatus includes an embedded cable modem which receives or transmits messages from or to an embedded set-top box through a number of unidirectional ports according to message types.

Abstract: An apparatus and method for executing a broadcast application are provided. The apparatus includes a data filter which extracts broadcast application data for executing a broadcast application provided by a predetermined broadcast channel among broadcast channels that are not currently watched by a user from a broadcast stream of the predetermined broadcast channel, data storage unit which stores the extracted broadcast application data, and an application execution unit which fetches the broadcast application data from the data storage unit in response to an application execution command input by the user after the user's selection of the predetermined broadcast channel and executes the broadcast application using the fetched broadcast application data.

Abstract: A method and apparatus for processing a timeout in a device that complies with the DSG standard are provided.

Abstract: A method and apparatus for filtering section data are provided. The filtering apparatus includes: a mask generation unit which generates a mask to be used for filtering section data based on a section number in a digital broadcasting receiver and the mask generation unit determines whether to generate the mask based on an accumulated number of bit number 0 or 1 at each bit position of a section number already stored in the receiver. According to the method and apparatus, a section number of section data received and stored by a receiver is not directly compared to a next received section number, and by using a mask generated based on the accumulated number of the received bit numbers, filtering is performed such that the time for performing filtering is reduced.

Abstract: An internet address system formed by introducing a E.164 number system of the ITU-T or a zip code system to IPv6 address system, and a hierarchical routing method using the same. Thus, a user can easily find an IPv6 address of a user terminal from his/her telephone number. The telephone numbers can be well linked to the IPv6 addresses, so that an internet provider can easily design and assign the IPv6 addresses. In addition, a hierarchical routing process is carried out by using the E.164 number system, thereby reducing routing time and improving a routing speed. The subscriber address can also be found out by the internet address of the subscriber. The IPv6 addresses and zip codes are well linked by applying the zip codes of the respective countries to the IPv6 address system, thereby efficiently using the information for network management and administration.
