Abstract: An electronic module for a digital television receiver comprises a multimedia CPU (211), a non-volatile memory block (212) connected with the multimedia CPU (211) via a memory interface (220) and storing a booter application for initializing the start-up of the digital television receiver, and a buffer (213) connected to the memory interface (220), configurable to enable or block access to the memory interface (220) for components (206, 209) external to the module. The invention provides a solution for securing the set-top box elements, including CA system elements and proprietary set-top box software, to prevent unauthorized access to them, their monitoring or replacement.

Abstract: A device with a PCB with forced airflow has a housing including a first panel (141) and a second panel (142). Within the housing is mounted a printed circuit board (111) with heat dissipating elements, an opening (112), a first surface (131) and a second surface (132). The first surface (131) of the printed circuit board (111) is located at a distance from the first panel (141) smaller than a distance between the second surface (132) and the second panel (142). To the printed circuit board (111) is mounted a fan (113) that covers the opening (112) and forces airflow from a space between the first surface (131) and the first panel (141) to a space adjacent the second surface (132).
Abstract: The present invention relates to an audio/video device (100) with a replay function containing a stream source (101) providing a replayable audio/video data stream, a user interface (108) for inputting stream play requests, a stream processor (102) coupled to the stream source (101) and to the user interface (108) providing stream play status and processing the stream according to the stream play requests, a tag memory (106) and a microphone (103) receiving ambient sound.
Abstract: In a smart card (100) with memory blocks (110, 120, 130) and a processor (140), one of the memory blocks (110) has a decryption keys area for storing decryption keys (111) and at least one of the memory blocks, which is non-volatile memory (130), has data storage area (131) for storing data sets, whereas the processor (140) is provided with a decryption keys interface (141) for handling requests for the decryption keys and a data interface (142) for handling requests for transmission of the data sets, from which at least one data set stored in the data storage area is decryptable using the decryption keys (111).
Abstract: In a system for controlling conditional access systems in a digital television decoder (101) with a signal receiving block (102) receiving a plurality of streams (TS1, TS2), a signal processing block (131) having a plurality of decoder descramblers (133, 135) and a conditional access block (141) with at least one conditional access system (143, 145, 147) provided with a client (142, 144, 146) supporting communication via a client interface (152), the conditional access block (141) additionally comprises a client manager (151) handling communication with conditional access systems (143, 145, 147) via clients (142, 144, 146) using the client interface (152) and controlling descrambling of the streams by granting access to decoder descramblers (133, 135) to selected conditional access systems (143, 145, 147). The client manager is provided with a plurality of virtual descrambler sets, where each virtual descrambler set is assigned individually to each decoder descrambler.
Abstract: A system for distributing content to client applications in a networked environment encloses a base content host having an application server providing base content responsively to requests from client applications. The base content (242) comprises at least one special element, referenced by a special locator pointing to a special content (252), the special locator generated by a special locator generator (243) of the base content host (240). The special locator distinguishes by a special locator host domain name consisting of a sequence of characters of which at least one is randomly generated, followed by an existing top level domain name. Apart from the base content host (240) the system comprises at least one special content host (250) having a special content host IP address and comprising an application server (251) providing the special content (252), responsively to requests from client applications.
