Trident Microsystems was a fabless semiconductor company that in the 1990s was a well-known supplier of graphics chipsets used in video cards and on motherboards for desktop PCs and laptops. In 2003, it transformed itself into being a supplier of display processors for digital televisions and achieved success starting from 2005, at a time when the global LCD TV market started showing strong growth.It filed for bankruptcy protection in January 2012 and the delisting of its common stock from the NASDAQ stock market was announced shortly thereafter.

A system and method to render 3D images from a 2D source are described. An embodiment of a method to render 3D images from a 2D source comprises the steps of providing a graphics rendering device to estimate depth of a 2D image; providing video or graphics textures and depth-maps to describe an object in a 3D scene; creating, in one embodiment, a single view angle and in another preferred embodiment at least two view angles of the 3D scene to represent an intraocular distance using the graphics rendering device; and presenting both of the at least two view angles on a display using the graphics rendering device and especially the commonly available 3D imaging technology of the graphics rendering device.

An image creation method uses first and second images which comprise 2D views of a 3D scene from different viewpoints. The images are combined to derive a third image representing a 2D view of the 3D scene from a third viewpoint, with greater pixel resolution than the pixel resolution of the first and second images. This method uses the fact that the stereo images are closely related, to enable construction from the two images of a third image of higher resolution. This third image can then be provided as a single higher resolution 2D image, or else the third image can be used to enhance one of the original stereo 2D images.

The invention relates to an apparatus and method for processing received data (I1/Q1, I2/Q2; d1, d2) of a radio interface, wherein the received data includes a sequence of data which have been transmitted for the purpose of error reduction through different branches of a carrier (R_(k)) of the radio interface, and which are combined into a sequence of data (DATAOUT) to be outputted, wherein the combining is implemented on the basis of carrier information values (R_(eq,k), SINR_(k)) of the different branches (k) relative to each other. A maximum ratio combining (MRC) is implemented in which the amplitudes of the branches of the carrier information (R_(eq,1),(R_(eq,2)) are combined using a division method as a function of a disturbance information value (MIX, SINR1, SINR2) of the branches (k).

A sub-title detection system and method for television video are provided in which a static region detection is performed, and the results of the static region detection are pruned using a feature based on density of horizontal transition pairs, an intelligent adaptive temporal filtering is performed that uses object-level subtitle information and has suitable properties for integration in a streaming video environment, rectangular bounding boxes are computed around the subtitle using height, width and filling-degree constraints, and finally, subtitle bounding boxes are identified by binary classification based on text stroke alignment features.


The invention relates to a Delta-Sigma Analog-to-Digital Converter circuit and method for analog-to-digital converting. The Analog-to-Digital Converter circuit comprises a quantizer (5) arranged and/or controlled for outputting a digital converted signal (Y) and a feedback path (6) with a Digital-to-Analog Converter (8) arranged and/or controlled for processing the converted signal (Y) and for feeding back the processed analog signal (ry). It is characterized in that the feedback path (6) comprises a digital filter (7) arranged before the Digital-to-Analog Converter (8), the digital filter (7) being arranged and/or controlled for digital filtering the converted signal (Y).


A generic apparatus (14) re-orders video data for various types of displays, such as plasma discharge panels (PDPs), digital micro-mirror devices (DMDs), liquid crystal on silicon (LCOS) devices, and transpose scan cathode ray tube (CRT) displays. In one embodiment, the apparatus (14) includes a first programmable transpose processor (18), a memory (20, 120), and a second programmable transpose processor (22, 122) fabricated as a single IC unit.


Patent
Trident Microsystems | Date: 2011-03-09

A method of generating presentation time stamps, PTSs, for motion-compensated frame-rate conversion of a sequence of frames. In one aspect, the method comprises for each new frame: determining an average difference between the capture time-stamps of recent consecutive new frames; and generating the PTS based on the capture time-stamp of a previous new frame and the average difference. In another aspect, the method comprises detecting a first cadence and a second different cadence in the sequence of frames; and generating a PTS for each new frame defined by the first cadence, such that in each case the difference between the PTSs of consecutive new frames is intermediate between the true interval between those frames according to the first cadence and the true interval between them according to the second cadence.

The invention relates to a method for outputting a first digital video stream (BTS). The method comprises: i) receiving a first transport stream (TS1) comprising a first plurality of time-multiplexed video channels (SRV1, SRV2, SRV3, SRV4); ii) buffering the first transport stream (TS1) to obtain a first buffered transport stream (BTS1); iii) selecting a first specific one from the first plurality of time-multiplexed video channels to obtain a first selected video channel (SRV1); iv) searching the first buffered transport stream (BTS1) for a first start (GOPS1) of a first group of pictures of the first selected video channel (SRV1), and v) outputting the first buffered transport stream (BTS1) starting from the first start (GOPS1) of the first group of pictures to obtain the first digital video stream (BTS). The invention further relates to a system for carrying out such method. The invention provides for very fast channel switching (zapping) due to the fact that the start of the group of pictures of the selected channel is available in the buffer almost instantly.
