Abstract: When distributing a set 101 of frames 102 each with encoded data 103 from a transmitter 104 to a receiver 105, a dependent frame 108 requires an independent frame 107 for decoding, and the transmitting 111 of the frames 102 from a buffer 110 at the transmitter 104 is reordered such that the dependent frame 108 is sent after the independent frame 107. In particular, a transmission policy wherein buffering 109 a further frame 125 takes into account both: if the further frame 125 requires zero, one or two frames 102 of the set 101 for decoding, and the current frames 102 buffered at the first and the second position 123 of the transmit buffer 110.

Abstract: A switch module is designed to facilitate user definition of a group of switch modules that control the same lamp. A lamp unit (12) containing the lamp responds selectively to messages from the switch modules (10, 10?) when the messages comprise ID information matching with ID information stored in the lamp unit (12). A group is formed by detecting user control operation of sensors (100) in the switch modules (10, 10?), transmitting messages from the switch modules (10, 10?) in response and determining from the messages whether the switch modules (10?) have both been operated within a time interval with a duration of less than a predetermined threshold. If so, the ID information value in memories (104) of the switch module (10) and/or the further switch module (10?) are set to matching ID values, for use in the messages to control the lamp unit.

Abstract: A lamp is provided that is controlled by messages transmitted via a network. The lamp has an internal memory that stores an address and an internal control circuit that responds to received messages that refer to this address. The address is updated when the lamp is installation in a power supply socket, using for example an address from the first message that is transmitted after installation. The lamp contains a detector that detects disconnection of the lamp from the power supply socket, for example by monitoring a resistance value between two parts of one of the power supply terminals of the lamp. In response to this detection the control circuit of the lamp sets information that enables an update of the address in the memory. When it is detected that the lamp is again connected to a power supply socket the address is updated on condition that the update is enabled.

Abstract: Controlling controllable devices (12) such as lamp units that are installed in a building (10) with a plurality of control interface units (14) such as light switches. Each control interface unit (14) has a receptor (20), such as a light switch, for receiving user actuations. Addresses to be used for selective transmission of messages to controllable devices (12) are established by enabling the control interface unit (14) that should control a controllable device (12) to read a tag (34) on or in the controllable device (12). The control interface units (14) each have their own a tag reader (26), capable of reading the tag (34) when the tag (34) is in a proximity of the control interface unit (14).

Abstract: An apparatus processes a video stream signal. The video stream signal represents a succession of frames, comprising a plurality of dependent frames that each provide for prediction of visual content using selectable ones of a preceding and following anchor frame that precede and follow the plurality of frames respectively. When a shortage of transmission bandwidth occurs, the apparatus generates a processed version of the video stream signal wherein a bit-rate alteration is performed starting from one of the dependent frames before an end of said plurality. Said alteration is executed by substituting a standard prediction from the following anchor frame at least for data in the video stream signal that encodes a region in said one of the dependent frames.

Abstract: The present invention relates to a method of splitting a data stream into packets which comprise either only video units or only non-video units in order to better enable the enhancement of a displayed video stream using IFD without causing any audio artifacts. The gist of the present invention is the insight and the realisation of splitting the data stream into smaller packets than is customary. Thus it becomes possible to produce packets comprising either video units or non-video units, and in case of video units, packets pertaining to only one video frame.

Abstract: A method of and an apparatus for writing data on and reading data from a recording medium such as an optical disc, a magnetic disc and, particularly, a tape are described. When a block of the medium is defective, the data to be written in said block is stored in an auxiliary memory. Subsequently, all the data from the auxiliary memory is copied to a predetermined spare area of the medium. Conversely, when the medium is read, data is first copied from the spare area of the medium to the auxiliary memory. If a block then appears to be defective, the correct information is read from the auxiliary memory. Thus, it is possible to write and read a real-time audio and/or video signal in a reliable manner without the possible presence of any defective blocks affecting the data transfer rate.

Abstract: A method of reducing the response time upon a change-over between different display modes of a video display device, picture information from a first channel being displayed in one display mode and picture information from another channel being displayed in another display mode. Picture information from the one channel is simulated by picture information from the other channel. The two channels may carry different picture information.

Abstract: The invention relates to manipulation of sub-pictures (303) in a picture such as a mosaic screen (301). An apparatus comprises a sub-picture generator (105) connected to a mosaic screen generator (107), which generates the mosaic screen (301) from the sub-pictures. The mosaic screen (301) is by a video compressor (111) divided into uncompressed picture blocks such that each block only comprise video data from one sub-picture. The picture blocks are compressed using a block compression scheme such as MPEG-2. The apparatus further comprises a video manipulation processor (113), which manipulates the sub-pictures by manipulating the association between control data in the video signal and the compressed picture blocks. The video data of the compressed picture blocks are not affected whereby de-compression and new compression is avoided.
