摘要:
A record carrier includes write status information indicating whether at least one area of the record carrier has been written, initial area status information indicating the extent of an uninterrupted initial area contiguously written from the start of a track pattern area intended for writing information blocks, and/or conformance status information indicating whether the record carrier is written to fully comply with the requirements of a standard that specifies requirements of reading devices or only partially complies with the standard for reading devices.
摘要:
Reading a partly written writable record carrier having a track structure for positioning the write head above unwritten areas of the track pattern by means of a reading device which positions the read head on the basis of written marks, yields problems when an isolated information block after an unwritten area must be read. A system is disclosed for writing and reading information blocks on a record carrier of a writable type such as a CD-RW or a DVD-RAM. The writing device is provided with status means for generating status information which is indicative of the fact that at least one area of the record carrier has been written, while the status information includes initial-area information which is indicative of an uninterrupted written initial area which extends from the start of a track pattern area intended for writing information blocks. The status information can be written on the record carrier. A reading device is also described, in which the positioning is dependent on the status information. Reading instructions with addresses outside the initial area can be rejected or translated via an address translation table into addresses in the initial area.

摘要:
The present invention relates to a method, load (12) and display device (10) where an output parameter value (V) of a power supply (14) coupled to a separate load (12) is regulated. The load (12) demands at least one such parameter value (V) from the power supply (14). The power supply (14) delivers the output parameter value (V) to the load (12). The load (12) comprises a control signal setting unit (16), which receives information relating to the output parameter value (V) and is connected to the power supply (14) for delivering a control signal (VC). The control signal (VC) includes information relating to the output parameter value (V) and is used by the power supply (14) for regulating the output parameter value (V). This makes the control signal setting unit (16) part of a feedback loop. The parameter value is preferably an output voltage, the load a plasma display panel and the display device a television set.

摘要:
Digital audio and/or video programs that have been compressed on the basis of groups of pictures (GOPs) are recorded on a medium that allows immediate jumping between groups through co-storage of Transport Stream packets and pointer information. In particular, coexistently with the storing, successive pointers are derived in realtime from a primary Transport Stream that collectively point to data packets in a reconstructed Transport Stream which contains entry points. These pointers are stored at predetermined locations on the medium.

An image display apparatus (100) is disclosed. The image display apparatus (100) comprises: a display device (104) for displaying an image, by emission of display light in a first direction; a scattering layer (102) disposed in front of the display device (104), for scattering a portion of the ambient light; and a reflective layer (106) disposed in between the display device (104) and the scattering layer (102) for reflecting a portion of the scattered ambient light into the first direction.
