Abstract: PROBLEM TO BE SOLVED: To shorten a time for downloading by tuning a receiver, assembling received contents data through broadcast transmission of a selected frequency, and transferring the data to a player for reproducing the contents data after all the contents data are received. SOLUTION: A filtering module(FM) 4 is tuned to a specified digital channel and starts filtering a desired package packet from a multiplexed broadcast stream. This filtered data block is transmitted to a contents host emulator(CHE) 2 which reassembles the package. When reassembling and format of the package are excellently executed, the CHE 2 transmits the package to a player application 195.

Abstract: PROBLEM TO BE SOLVED: To provide users with a method for surely receiving data on a system from a web broadcast communication interface through a plurality of channels. SOLUTION: This method includes a step, where promotion meta data that are available for reception are received through a 1st web broadcast communication channel and at least part of the data is assembled into promotion offering data, a step where data to be received are selected in relation to the above data, a step where data are received from a 2nd web broadcast communication channel, a step where the data are selected from the promotion meta data and encrypted by using a 1st encryption key, and a step where a computer- readable medium receives a 1st encryption decoding key, and the decoding key is used to decode at least part of the encrypted data received from the 2nd web broadcast communication channel.

Abstract: A method for receiving digital content data on a user's system for playing or recording, the content data being compressed and encrypted with a first encrypting key, said method comprising the steps of: tuning a receiver to a selected frequency; receiving content data through a broadcast transmission at the selected frequency; assembling the content data that is received; and transferring the content data to a player for playing the content data after all the content data has been received. In accordance with another embodiment of the present invention, an information processing system and computer readable medium is disclosed for carrying out the above method.

Abstract: A digital rights management system for controlling the distribution of digit al content to player applications, the system comprises a verification system, a trusted content handler, and a user interface control. The verification system is provided to validate the integrity of the player applications; and the trusted content handler is used to decrypt content and to transmit the decrypted content to the player applications, and to enforce usage rights associated with the content. The user interface control module is provided to ensure that users of the player applications are not exposed to actions that violate the usage rights. The preferred embodiment of the present invention provides a system that enables existing content viewers, such as Web browsers, docume nt viewers, and Java Virtual Machines running content-viewing applications, with digital rights management capabilities, in a manner that is transparent to the viewer. Extending content viewers wit h such capabilities enables and facilitates the free exchange of digital content over open networks, such as the Internet, while protecting the rights of content owners, authors, and distributors. Th is protection is achieved by controlling access to the content and constraining it according to the rights and privileges granted to the user duringthe content acquisition phase.
