摘要： Methods and arrangements are disclosed for embedding and detecting a watermark in a cinema movie, such that the watermark can be detected in a copy made by a handheld video camera. The watermark embedder divides each image frame into two areas. A watermark bit ‘+1’ is embedded in a frame by increasing the luminance of the first part and decreasing the luminance of the second part. A watermark bit ‘−1’ is embedded by decreasing the luminance of the first part and increasing the luminance of the second part. It is achieved with the invention that the embedded watermark survives ‘de-flicker’ operations that are often used to remove flicker caused by the different frame rates of cinema projection equipment and consumer camcorders.

摘要： A method for driving a light source (11, 12, 13) is described, wherein the light source is alternately switched ON and OFF in an ON/OFF pattern, wherein the duty cycle of the ON/OFF pattern is varied to vary the average light intensity of the light source, and wherein the shape of the ON/OFF pattern is varied to transmit data. Thus, a control signal for the light source comprises data information as well as duty cycle information. The duty cycle is varied within a range from almost zero to almost 100%, and data is varied and transmitted without affecting the duty cycle.

摘要： A diversity receiver receives high rate radio signals (for example DVB-T signals) while the receiver is moving at a high speed (for example in or with a car). Two or more antennas are closely spaced and arranged behind each other in the direction of motion for receiving the radio signals. A difference (S2(t)−S1(t)) of a first signal (S1(t)) obtained via the first antenna and a second signal (S2(t) obtained via the second antenna serves as an estimation of the spatial derivative of the receiving channel transfer function. This spatial derivative is interpreted as a temporal derivative and exploited to cancel or at least reduce distortions (for example ICI) due to rapid receiving channel variations.

摘要： There is provided a method (700, 900) of selecting nodes (120, 130, 140) in a communication network (100), in which a source node (110) communicates with destination nodes (120, 130, 140). The method (700, 900) includes steps of: (a) transmitting a first message (770, 950) from the source node (100) to the destination nodes (120, 130, 140); (b) receiving response messages (780, 960, 980, 990) at the source node (110) from one or more of the destination nodes (120, 130, 140); (c) in an event of contention arising between the response messages (780, 960, 980, 990) received at the source node (110), iteratively selecting a sub-set (510, 520, 610, 620) of the destination nodes (120, 130, 140) to resend their response messages for receipt at the source node (110) until the response messages are received at the source node (110) without contention, the response messages received without contention being indicative of a suitable destination node having been selected. The method is executable in a communication network (100) for rendering the network (100) more reliable with enhanced quality-of-service (QoS).

摘要： The invention relates to controlling a lighting device, particularly to the modulation of light generated by a solid state lighting (SSL) device. The invention provides a method and device for modulating the light emission of a lighting device by keying each pulse (14) of a sequence of pulses (16) contained in the control signal (10) according to a spreading code. Thus, the light emission of a lighting device may be identified by detecting the spreading code used for modulating the light emission. The invention is particularly suitable for lighting means containing several lighting devices such as a LED lighting board with dozens of LEDs since the light emission of each lighting device may be detected by the spreading code used for modulating the light emission.

摘要： The invention relates to a method of storing data on a rewritable data storage medium, to a corresponding storage medium, to a corresponding recording apparatus and to a corresponding playback apparatus. Copy-protective measures require that on rewritable storage media some data must be stored which shall not be modifiable or erasable by consumer end products. A practical problem is the storage of large quantities of such data in a fixed data area. Typically the capacity is limited to a few bits. Meanwhile the amount of copy protection data that needs to be stored may well exceed the storage capacity available in the read-only fixed data area. The invention therefore proposes to write the copy protection data as system data in the recordable data area (4), e.g. as part of the formatting of the medium (1). A cryptographic summary is computed and also stored in the recordable data area (32) or in the fixed data area (2) such that a cryptographic relationship between the fixed data area (2) and the system data area (3) is provided. A playback or replay apparatus will only accept a storage medium with a valid combination of copy protection data and fixed data.

摘要： Described is a transmission system for transmitting a multicarrier signal from a transmitter (10) to a receiver (20). The multicarrier signal comprises a plurality of subcarriers. The receiver (20) comprises a channel estimator (28) for estimating amplitudes of the subcarriers and for estimating time derivatives of the amplitudes. The receiver (20) further comprises an equalizer (24) for canceling intercarrier interference included in the received multicarrier signal in dependence on the estimated amplitudes and derivatives (29). The channel estimator (28) and/or the equalizer (24) are arranged for exploiting an amplitude correlation between the derivitives of different subcarriers. By making use of this correlation the complexity of the receiver (20) can be substantially reduced.

摘要： Methods and arrangements for processing a signal using a digital processor having a given word length. The signal is pre-processed using a pre-processor which reduces the word length and performs an operation which is invariant with respect to a process being performed by the digital signal processor. This means that if the pre-processor operated with infinite accuracy, it would have no effect on the subsequent process. If such a pre-processor operates with infinite accuracy, it will reduce the guantization noise. In the digital signal processor, the pre-processed signal may be transformed into frequency coefficients which are normalized directly thereafter.
