摘要： A DAB receiver, an apparatus and a method for converting a first sequence of data having a fixed frame structure, wherein locations within the frame are reserved for predetermined data types, into a second sequence of data, having a different frame structure. The data belonging to the respective data types are grouped in separate sequences with a frame type identifier attached to the sequences for identifying the different sequences. This allows an easy identification of the different sequences of data within the second sequence without the need of prior knowledge of the exact location of the sequences within the second sequence. An example of such a conversion is the conversion of the channel decoder output of a DAB receiver into a format suitable for embedding in the IEC958 format.

摘要： A video tuner (1), a video signal (recording and) reproducing arrangement (7) and a picture display unit (35) are coupled to each other via a switching circuit (9). The video tuner (1) can supply first and second video signals on its output (3), representing pictures having a first and a second aspect ratio respectively (4:3 and 16:9, respectively). These signals can be recorded and reproduced by the video signal (recording and) reproducing arrangement (7) and can be displayed with the correct aspect ratio by the picture display unit (35). In order to realize this, a control signal line (55) is arranged between a control signal output (4) of the tuner (1), a control signal input and output terminal (10) of the video signal (recording and) reproducing arrangement (7) and control signal inputs (36) of the picture display unit and (46) of the switching circuit and control signal detector (9, 45). The video tuner (1) produces a first or a second control signal (S1 and S2) on the output (4) depending on the aspect ratio of the pictures in the supplied video signal while the video signal (recording and) reproducing arrangement (7) produces a third or a fourth control signal on the control signal input and output terminal (10) depending on the aspect ratio of the pictures in the video signal being reproduced. The switching circuit and detector (9, 45) select between the control signals in such a way that if the first or the second control signal is applied, the output signal of the video tuner (1) is selected, and if the third or the fourth control signal is applied, the output signal of the video signal (recording and) reproducing arrangement (7) is transferred to the picture display unit (35). The picture display unit (35) selects between the control signals in such a way that video signals applied to the input (37) are displayed with the correct aspect ratio on the display screen (39).

摘要： An optical end-of-tape detection device comprises a photodiode and a phototransistor. In order to distinguish the light emitted by the photodiode from the ambient light, the photodiode is operated in a pulsating fashion. Moreover, the low-frequency component of the photo current supplied by the photo-transistor is suppressed by negative current feedback.

摘要： A PAL comb filter having a first and a second parallel transmission path. The first path includes a time delay network. This time delay network has a time delay equal to one line period H instead of two line periods as in conventional PAL comb filters. For this purpose a PAL inverter is arranged in one of the two paths. Alternatively, said PAL phase inversion can be switched in such a way that said inversion is effected either in the first or in the second path, change-over causing an additional PAL phase inversion of the output signal of said comb filter, which may be employed in video recording systems with parallel tracks in which the PAL phase is aligned in directions perpendicular to the tracks by the use of additional PAL phase inversions during recording, and in video recording systems in which said alignment is not used, in order to ensure, inter alia during fast-motion playback, that the PAL phase inversion sequence in the reproduced signal is not disturbed.

摘要： A video system comprises a video signal generating device (1') and no less than one video signal receiving device (2') coupled to each other by means of a signal bus (4'). The video signal generating device (1') is capable of generating at an output (13) one or a plurality of video signals having each a different signal format (CVBS, Y/C, MAC bb, . . . ). The video signal receiving device(s) is (are) arranged for processing one or a plurality of video signals having mutually different formats. It is an object to establish which video signal format the devices (1', 2', 3') have in common (Y/C) and to adjust the devices so that the video signal generating device generates at its output (13) just the video signal that has the common signal format concerned and the video signal receiving device(s) is (are) capable of processing the video signal that has the common signal format concerned and is applied to the input (24, 33). If two or more video signal formats appear to be common to the devices a choice is made in favor of one of these formats, preferably the video signal format having the highest video signal quality.

摘要： Graphic images that overlay a transmitted video signal are provided in the form of bitmaps that allow any character or font size to be displayed. A color-look-up-table (CLUT) at a receiver is defined that maps “m” inputs to a combination of color and luminance values for display. One or more map tables are provided that allow pixel colors to be encoded using fewer than “m” bits, the map tables providing an “m” bit output for accessing the CLUT. The provider of the graphic images can also specify a required minimum number of CLUT colors for rendering the images; if this minimum is greater than “m”, the image is not rendered. The use of map tables provides compatibility between a variety of encoding techniques and a variety of rendering devices, without requiring different CLUTs to be transmitted for each different color encoding format.

摘要： The application relates to an information transfer system, comprising a receiver (3) and a transmitter (1) for transferring an information signal to the receiver (3) via a transfer medium (2). The information signal comprises main data and sub data. The sub data comprises coded text lines having a plurality of character codes. The receiver is provided with a character display unit (10) for displaying characters corresponding with the character codes in the coded text lines. The number of character display positions is less than the number of character codes in the coded text line. The receiver is provided with display control means (9) for controlling the display of characters corresponding to the character codes included in the coded text line in dependence on serial control codes included in the coded text line. The system enables that significant parts of the text information available in the sub data can be shown on both a full multi-line display units for displaying full text lines and a 1-line display with a relative small number of digits. The invention is very suitable for systems with small sized receivers, such as e.g. portable players and car radios, and receivers wit a display on its remote controller, because there is not much space available for a display unit.

摘要： A receiver and a method for adding a sequence, embedded in a digital sequence of data together with another sequence, separate of the other sequence to at least a part of the digital sequence of data. An example of such a sequence is the Program Associated Data (PAD) in a DAB digital sequence of data, this PAD being embedded in audio frames together with audio data. The DAB digital sequence of data is converted into a sequence according to the IEC958 format, wherein the retrieved PAD is inserted into the User Data channel in the IEC958 frames. This allows an easy retrieval of the PAD from the digital sequence of data, without the need for analyzing audio frames and retrieving the PAD therefrom.
