20080310451 | Splitting of a Data Stream - 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. | 12-18-2008 |
20090016435 | REPLACEMENT OF FRAME DATA IN A VIDEO STREAM SIGNAL - 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. The bit rate alteration is accompanied by a switch to a mode in which the processing circuit substitutes a standard prediction from the following anchor frame in all following dependent frames that follow said one of the dependent frames until the following anchor frame, for data in the video stream signal that encodes the region in said following dependent frames. In an embodiment interlacing is killed for the replaced regions. | 01-15-2009 |

20120098428 | MESSAGE CONTROLLABLE LAMP - 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. | 04-26-2012 |
