Abstract: The present disclosure aims to provide a communication apparatus capable of achieving media distribution with a high quality of user experience. A communication apparatus is a communication apparatus configured to distribute media data to another communication apparatus via a plurality of lines, the apparatus including: a communication quality estimation unit configured to estimate communication qualities of the respective lines; a bit rate determination unit configured to calculate, from the estimated communication qualities of the respective lines, an index value indicating a quality of user experience when each of the lines is used and determine a bit rate of the media data based on the calculated index value; and a data allocation unit configured to allocate a data amount of the media data to the respective lines based on the estimated communication qualities of the respective lines and the bit rate that has been determined.

Abstract: A driver assistance system for a vehicle includes an imager disposed in the vehicle and viewing forward of the vehicle through the vehicle windshield. The imager has a field of view exterior the vehicle and is operable to capture image data. The imager includes (i) a lens, (ii) a spectral filter and (iii) a CMOS photosensor array of photosensor elements. The system includes a control that may be operable to process captured image data for at least a first application and a second application, with the first application including lane departure warning and the second application selected from the group consisting of (i) headlamp control, (ii) vehicle detection and (iii) rain sensing. The control may be operable to adjust a parameter or setting of the imager.

Abstract: Video processing arrangement including a host computer, a video asset coupled to the computer for generating video signals, and an interface for connecting the video asset to the computer to enable the display of the video signals on a monitor. The video asset includes primary elements such as a primary composite video module that produces different types of a primary video signal and outputs the primary video signal, and a secondary video source module that produces a secondary composite video signal and outputs the secondary composite video signal. The primary composite video module includes a memory component including a user-programmable sequence of bits representative of a video signal and user-programmable signal generators synchronized to the primary video signal output of the primary composite video module. The memory component includes four user specified pulse memories which each hold a series of arbitrary bit line patterns.

Abstract: An apparatus and methods that facilitate efficient and easy installation of a display screen and protective shield onto a cabinet of a display unit such as a projection TV (PTV) and the like. Preferably, a screen frame and bezel clip system includes a bezel clip having a latch arm releaseably coupleable to catch arm extending from or attached to a cabinet side wall of a display unit. The bezel clip further includes one or more receptacles sized and shaped to receive and retain a side or edge portion of one or more screens. The catch arm is preferably deformable under pressure and returns to a pre-stressed orientation when the pressure is removed. Alternatively, a screen frame and bezel mount system includes a stiffener member adapted to couple a bezel member to a cabinet side wall of a display unit. The bezel member includes one or more receptacles sized and shaped to receive and retain a side or edge portion of one or more screens.

Abstract: Processes for selecting, manipulating and arranging data points or pixels derived from information bearing signals are useful to reduce the bandwidth of, or improve the perceived quality of, such a signal as transmitted and displayed. The techniques utilize time-varying sampling schemes and take into account the characteristics of the human visual system. For each information frame, a subset (3) of all possible data points (1) is selected (2). A further subset of active data points (5) is selected (4) for which data will actually be sampled. The active points (5) are further divided (6) into points for which a value will be transmitted (x-points) (7) and points which will be sampled but for which no separate value will be transmitted (o-points) (8). A mathematical association between the x-points and o-points is made (9) and new values to be transmitted are calculated for the x-points (10).

Abstract: A screen mounting device for a projection TV includes a mask for protecting an edge of a screen on which an image is displayed which is arranged to enclose an edge portion of the screen and having a hooking socket formed at a back side thereof, and a holder member for fixing the screen s and the mask to the cabinet. The holder member includes a coupling portion fitting in a front edge portion of the cabinet and fixed thereto, a hooking portion inserted in the hooking socket of the mask and coupled thereto, and a screen fixing portion in which the edge portion of the screen is inserted. Also, the coupling portion, the hooking portion and the screen fixing portion are integrally formed.

Abstract: Methods and devices for incorporating additional information, such as HDTV side strips, into the blanking intervals of a previous frame. These may be used in conjunction with Inventor's time-varying STS techniques or otherwise. The information thus incorporated may be used, in addition to HDTV side strips, for the incorporation of data that may represent: additional definition; information that may be used to convert a monoscopic image into a left and right pair, or the second of a pair; various area maps which may be used to apply a multiplicity of algorithms to separate areas of an image; motion analysis information; interactive or gaming information; multimedia or hypermedia information; or, otherwise. Off-line computation and recording may be used to advantage at the encoding end of the process, as well as pipelined architecture at the reception end.

Abstract: An improved screen aspect ratio conversion apparatus displays a 4:3 broadcast signal on a screen having an aspect ratio of 16:9 by expanding the screen aspect ratio to 4:3 in an interpolation unit and by removing a portion exceeding a certain range of the screen aspect ratio of 16:9.

Abstract: An RGB preamplifier for a video display includes respective multipliers independently operable for adjusting the contrast of input primary and secondary video signals. The contrast adjusted video signals are added to form a combined display signal, the combined signal being applied to the first inputs of primary and secondary comparators each of which is also supplied with a respective reference DC level. The primary and secondary video signals are alternately nulled at horizontal line rate by nulling the corresponding multipliers. The primary comparator samples the combined signal when the secondary signal is nulled for clamping the DC level of the primary signal in relation to the primary reference DC level and the secondary comparator samples the combined signal when the primary signal is nulled for clamping the DC level of the secondary signal in relation to the secondary reference DC level.
