Provided are apparatuses and methods in a digital broadcast transmission system for receiving, processing and rendering transmitted content. A digital receiver capable of receiving and rendering both DVB-H and DVB-T signals may include a coupling means for connecting to another terminal for receiving program data or parameters. The digital receiver may reconfigure one or more components in order to handle the differing signal types. Such a receiver system allows a user to move seamlessly from a mobile device to a stationary device without significant effort and time. The receiver may further use transmission streams of varying priority to enhance and otherwise modify the displayed content according to a user's selection. Users with small display screens or poor eyesight may benefit from such enhancements features.

Combined receiver for DVB-H and DVB-T transmission

A system and method is disclosed for providing DRM in a broadcast environment. In accordance with the embodiment, a DRM system distributes encrypted service keys over the mobile telephone network to a mobile terminal. The mobile terminal receives the encrypted service key and uses it to decrypt encrypted content keys received from a DVB set top box. The decrypted content keys are sent to the set box over local link where they are used to decrypt encrypted broadcast content. A power management technique for mobile receivers is also disclosed that enables the receiver hardware to power off during a portion of the rendering process.

System and method for using DRM to control conditional access to broadband digital content

A method is provided for downloading audio characteristics to terminal equipment. A score information part is provided describing the presentation instructions of an audible signal. An instrument information part is also provided describing the parameters for synthesizing an audible signal the presentation instructions of which is described by the score information part. Additionally some compatibility information is provided describing the compatibility of the score information part and the instrument information part with certain processing and storing capacity. As a response to a selection command the score information part and the instrument information part are downloaded to terminal equipment through a communication network.

Method and arrangement for providing customized audio characteristics to cellular terminals

A system and method is disclosed for providing DRM in a broadcast environment. In accordance with the embodiment, a DRM system distributes encrypted service keys over the mobile telephone network to a mobile terminal. The mobile terminal receives the encrypted service key and uses it to decrypt encrypted content keys received from a DVB set top box. The decrypted content keys are sent to the set box over local link where they are used to decrypt encrypted broadcast content.

System and method for using DRM to control conditional access to DVB content

A personalized smart card stores therein public and private cryptography keys stored which are used to securely request and receive subscriber content data from a service provider, utilizing a remote control device.

Method and system for providing secure subscriber content data

A system, method and apparatus are described for delivering software to a terminal. Before software is delivered, an emulatoris invoked to validate the operation of the new software in conjunction with the existing terminal configuration. The invention is particularly suitable to the delivery of so-called thin terminal implementations by manufacturers to which users subsequently add their desired software.

Communication terminals

A method is provided for downloading audio characteristics to terminal equipment. A score information part () is provided describing the presentation instructions of an audible signal. An instrument information part () is also provided describing the parameters for synthesizing an audible signal the presentation instructions of which is described by said score information part. Additionally some compatibility information () is provided describing the compatibility of said score information part and said instrument information part with certain processing and storing capacity. As a response to a selection command (), () said score information part and said instrument information part are downloaded to terminal equipment through a communication network.

Equipment (,) is used for the reception of multimedia presentations and for their playback to the user, said equipment comprising a storage and presentation apparatus such as a computer (,) or television (,) and a terminal of a bidirectional communications system such as a mobile phone (,) or cordless phone (,). The multimedia information is loaded dynamically, and keys needed to descramble scrambled transmissions are delivered to the user via a bidirectional communications system. In the terminal equipment a local agent (,) which uses only a little of system capacity takes care of information loading and checks the available resource. Bidirectional communications can also be used for making payments to the producer and/or distributor of the multimedia service in the form of operations similar to telebank services.
