Abstract: The invention proposes a novel technique for coding video for a plasma display panel, which aims to improve the use of rotating code. The method forming the subject of the invention carries out a coding of the highest grey level V1 over the entirety of the subscans while favouring the subscans whose illumination time is the lowest. The coding of the lowest grey level V2 is achieved using the common value COMMAX which results from the coding of the value V1 if the specific value SPEMAX is greater than the difference D of the grey levels. If SPEMAX is greater than the difference D, then the coding of the common value COMMIN corresponds to the lowest value V2.

Abstract: A circuit board arrangement facilitates a direct connection to a chassis mounted connector. The arrangement comprises a printed circuit board with a first signal conductor terminating at an edge of the printed circuit board. A second signal conductor is disposed adjacent to the first signal conductor and terminates at the edge. A conductive metallic spring clip has a relieved area and is formed to fit over the edge of said printed circuit board. The conductive metallic spring clip is positioned on the edge of said printed circuit board such that the relieved area straddles the first signal conductor and the conductive metallic spring clip grips the second signal conductor for coupling the second signal conductor to the chassis mounted connector.

Abstract: When a played scene of a VCR (sequential access recorder) (90) is overwritten or added to the play list derived from the cut edit of the video scenes already stored in a disk (random access recorder) (140) according to the first instruction of a user, a selector (96) switches the play output of the disk following the play list and said played scene of the VCR to provide it to a monitor (6A) so that the user can confirm the edit result during the recording in real time. If there is the second instruction (VIEW instruction) during the recording, it plays the same edit result of the disk (140) again based on the renewed temporary play list to provide it to the monitor (6A) without interrupting the recording. On this occasion, it approves the user to change the play speed and stops advancing the play if the user try to play beyond the recorded point.

Abstract: The invention provides a novel scanning technique aimed at reducing the phenomenon of contouring. The scanning technique of the invention consists in adding at least one redundant subscan SP0 to SP4. The purpose of the redundant subscans SP0 to SP4 is to place an additional illumination time which is privileged. The redundant subscan SP0 to SP4 thus introduced makes it possible to have a steady illumination time virtually independent of the grey level and therefore to minimize the high-weight switching effects.

Abstract: The invention is related to a new kind of dithering method for plasma display panels. In a former Europena Patent Application a dithering method for the plasma display technology has been presented that utilizes a 3-dimensional dither pattern for the repeated use in a video sequence. A first dimension corresponds to a number of video frames, a second dimension corresponds to a number of video lines, and a third dimension corresponds to a number of cells or pixels in a video line. It has been found that this dither pattern has for some video levels the drawback of a generating a noticeable pattern in homogenous surfaces on the screen that reduces the picture quality. In order to overcome this drawback the invention proposes a new degree of freedom for the dither pattern. Different dither patterns are provided for different entries in a number of least significant bits of the data word representing the input video level.

Abstract: An improved addressing scheme for plasma display panel control comprises partitioning the panel into a number of sections and splitting the addressing period into correspondingly small addressing periods for each section. By varying the time distance between successive addressing periods of the sections from one sub-field to the other, at least for the sub-fields with higher weights, a better spread of the energy input and output of the plasma display panel is achieved and the power supply circuit for the display panel may be constructed with less expensive components.

Abstract: A method for picture coding and also in a corresponding method for the decoding of a picture. In the case of the first picture coding method, a digital picture is divided into at least two sections, which are then combined with one another before being coded. In this case, a combined pixel is generated in each case from the corresponding pixels in the sections to be combined, in such a way that the combined pixel is allocated an unambiguous type (A, B, C, D) which corresponds to the distribution of the pixel values in the pixel N-tuple of the corresponding pixels. The method for pixel coding can also be designed in such a way that two successive pictures of a picture sequence are, in the same way, combined with one another before being coded. A method for constructing a sub-picture data unit for an electronic apparatus, in particular an apparatus appertaining to consumer electronics such as e.g. a DVD apparatus, being intended, where such sub-picture data units are used.

Abstract: The invention concerns a method (200) for playing data in a digital video disc (DVD) apparatus in which the data was recorded onto a non-DVD optical storage medium in a DVD format. The invention includes the steps of: determining (212) the physical type of the non-DVD optical storage medium; reading (214) a file structure contained on the non-DVD optical disc medium; and launching (216) a DVD video playback driver if the file structure on the non-DVD optical storage medium is a DVD file structure. In one arrangement, the physical type of the non-DVD optical storage medium can be determined by checking a focal length in which the focal length is defined by a laser and a reflective surface of the non-DVD optical storage medium. The invention also concerns a DVD apparatus (100) capable of playing data recorded on a non-DVD optical storage medium in a DVD format.

Abstract: With the new plasma display panel technology new kinds of artifacts can occur in video pictures due to the principle that brightness control is done with a modulation of small lighting pulses in a number of periods called sub-fields. These artifacts are commonly described as ‘dynamic false contour effect’. A technique called bit line repeat coding has been developed for reducing the false contour effect. According to this technique sub-field coding is done with common (CSF) and normal sub-fields (SF) where for the common sub-fields (CSF) identical entries in the sub-field code words of two or more corresponding pixels on two or more pixel lines are used. In this specific sub-field coding method some cases will occur in which an error has to be made due to the reduced flexibility in encoding produced by the need to have the same code on common sub-fields (CSF).

Abstract: Plasma Display Panels (PDP) are becoming more and more interesting for TV technology. Due to the larger size of PDPs, with larger viewing angle the large area flicker effect will become more serious in the future, in particular when handling 50 Hz video standards. This invention proposes a different sub-field organisation, with different coding, which reduces large area flicker artefact, and which includes grouping of sub-fields in two sub-field groups wherein the two sub-field groups are identical in terms of the most significant sub-fields and different in terms of the least significant sub-fields, and a sub-field coding process that distributes luminance weight symmetrically over the two sub-field groups so as to minimize the large area flicker luminance component.

Abstract: The invention includes a system and method for changing a playback speed of a selected video segment having a non-progressive frame structure which has been recorded onto a portion of a storage medium. A selected video segment can be modified for a changed playback speed and the modified video segment can be recorded exclusively on the portion of the storage medium. A plurality of non-video packs in the selected video segment can be deleted to reduce the amount of data contained in the modified video segment. The video segment can be modified by decoding the frames in the video segment, reencoding such frames into their associated field pictures and adding at least one field picture. Alternatively, the video segment can be modified by removing at least one frame or field picture contained in the video segment. In either arrangement, the video segment can be reencoded to produce a smoother trick mode and playback performance.
