摘要： A wireless extension of the IEEE 1394 bus where two clusters of 1394 devices are linked by a wireless bridge. The device clusters communicate without being bridge-aware. The wireless bridge provides for a bus reset isolation. The wireless extension including a buffer memory for storing self-identification packets in the 1394 interfaces of both boxes of the wireless bridge. With these buffer memories the self-identification packets of the bus stations in the other cluster can be collected and they can be read out during the self-configuration phase of the network after a bus reset when the bus grant is assigned to the box of the wireless bridge that is also connected to the bus where the bus reset has occurred. The physical layer block of the 1394 interface transmits artificial self-identification packets for all bus stations of the other cluster.

摘要： An electrical insulation device for bidirectional connecting lines is proposed which operates reliably at high frequencies and can be integrated easily on a chip. In accordance with a first embodiment, for the purpose of electrical isolation, two separate optocouplers are provided per bidirectional connecting line. A control unit evaluates the control signals which are output by one of the two circuit units, and thereupon activates one of the two optocouplers while the other optocoupler is simultaneously deactivated, in order, in this way, to allow transmission of signals via the associated connecting line in one direction. In a second embodiment of the invention, only a single optocoupler is provided per bidirectional connecting line. The control unit is provided in this solution as well, except that in this case it changes over the effective direction of the optocoupler by means of corresponding circuit components, thereby once again achieving transmission of signals via the associated connecting line in one direction.

摘要： Today the storage of audiovisual (AV) data on storage media employs standardized coding schemes, e.g. MPEG-2. End user devices for AV presentation, like disc players, contain dedicated decoders implemented in hardware, which are able to decode data streams complying with the respective standard. The efficiency of this decoding methodology relies on the standardization of appropriate coding schemes. Proprietary coding schemes may be more efficient by being adapted to the content, or may be used for content protection or optional features. Using reconfigurable decoder hardware, storing the configuration data for the actual decoder on the same storage medium as the AV data, and downloading the data to configure the player can be used to implement proprietary coding schemes. Such schemes require appropriate player hardware, suitable to execute a downloaded decoder under real-time conditions, and a standardized format to store the decoder configuration data.
