    摘要: For some video processing applications, most notably watermark detection (40), it is necessary to add or average (parts of) the two interlaced fields which make up a frame. This operation is not trivial in the MPEG domain due to the existence of frame-encoded DCT blocks. The invention provides a method and arrangement for adding the fields without requiring a frame memory or an on-the-fly inverse DCT. To this end, the mathematically required operations of inverse vertical DCT (321) and addition (322) are combined with a basis transform (323). The basis transform is chosen to be such that the combined operation is physically replaced by multiplication with a sparse matrix (32). Said sparse matrix multiplication can easily be executed on-the-fly. The inverse basis transform (35) is postponed until after the desired addition (33, 34) has been completed.

    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: A method of selecting a light source among a plurality of light sources by means of a remote controller includes the remote controller: instructing, by omnidirectional transmission, the light sources to each transmit a directional signal comprising a code, which is unique for each light source; receiving the directional signals from the light sources; and selecting one of the light sources on basis of the received directional signals. Furthermore, the method includes: generating, remotely of the light sources, codes to be transmitted by the light sources; and the remote controller instructing each one of the light sources which one of the remotely determined codes to transmit.

    摘要: The present invention relates to a method for selecting at least one of a plurality of controllable devices (121-123), wherein each of the controllable devices (121-123) is adapted to transmit a distinguishable signal. The method comprising the steps of receiving (301) the signals from the plurality of controllable devices by means of a plurality of receiver modules comprised in a control device (110), wherein each receiver module separately detects a contribution of the signals; determining (302), using a correlation between the different signal contributions, a width and an angle of incidence for each of the signals; comparing (303-304) the width and the angle of incidence for each of the signals with a set of predetermined criteria; and selecting (305) at least one of the plurality of controllable devices best matching the set of predetermined criteria.
