Abstract: A cooling arrangement for a printed circuit board with a heat-dissipating electronic element comprises a radiating layer (108, 208, 308) on the top side of the PCB (100, 200, 300) and a covering (103, 203, 303) for thermally connecting the top side of the heat-dissipating electronic element (101, 201, 301) and the radiating layer (108, 208, 308), wherein the heat-dissipating electronic element is mounted on the bottom side of the PCB and the PCB is mounted horizontally. The covering can be made of a good heat conductor, e.g. copper, while the bottom side of the covering can be protected by a heat-insulating layer (105, 205, 305). The covering can have plain (104A, 204A) or notched (104B, 204B) arms.

Abstract: In a system for storing and searching for tags in a data stream, a signal processing block (120) contains a tag analysis block (121) providing functionality of procedures of searching and storing tags within an audio/video data stream. The tag analysis block (121) is provided with a configuration table (122) for storing configuration data for various types of recordings, defining distances of searching and storing tags. In this system a user tag is inserted at a place of existing tag when an existing tag distance is shorter or equal to a predefined tag searching distance. Otherwise, when there is no existing tag within the predefined tag searching distance, the user tag is inserted at the predefined tag searching distance.

Abstract: The present invention relates to a memory card (201) for a digital television decoder, which has a memory block (202) with a separate data memory area (205). The separate data memory area (205) can have the size from ten megabytes to a few gigabytes and can be used for storing audio/video data, audio data or application programs for the digital television decoder. The card also comprises a conditional access circuit (207) for descrambling of data stored in the separate data memory area (205), and a controller (206) for controlling the data flow inside the card. The controller (206) allows replay of data from the separate data memory when the conditions for replay of data, stored separately for each data file, are met.
