Abstract: A transmission efficient packet based display interface arranged to couple a multimedia source device to a multimedia sink device is disclosed. The transmission efficient interface includes a bi-directional auxiliary channel arranged to transfer information between the multimedia source device and the multimedia sink device and vice versa, wherein the information transferred over the auxiliary channel includes a set of packet attributes. The interface also includes a unidirectional main link arranged to carry a number multimedia data packets from the transmitter unit to the receiver unit each having a multimedia data packet header. In the described embodiment, each of the headers is substantially reduced in size over what would otherwise be necessary since the packet attributes are communicated via the auxiliary channel prior to the transmission of the main link packets over main link thereby minimizing the packet overhead and providing a very high main link efficiency.

Abstract: An all-digital frequency conversion apparatus is provided that achieves frequency conversion using a simple phase detector and integer and fractional phase feedback information from a digital oscillator output. In an embodiment, a target phase accumulator unit generates a target phase signal to the phase detector unit. The target phase accumulator unit receives inputs from a reference signal input, and a target phase input value. The digital phase detector unit receives the reference signal, a current phase feedback input signal, and the target phase input signal. The phase detector unit outputs a frequency setting signal to a frequency value generator unit. The detector output is based on the difference between the current phase and the target phase. A frequency value generator unit is configured to output a frequency value signal to a digital oscillator unit that generates a corresponding digital output signal that is directly fed back to the current phase feedback input of the phase detector unit. A method, computing system, and software product that implement the present invention are also provided.

Abstract: A system is provided for performing real-time warping in one or two dimensions (eg. dynamic zoom and shrink in both horizontal and vertical directions), and temporal warping of image frames (eg. fast motion and slow motion). The system accomplishes warping with proper Nyquist bandlimiting. Three different processes are performed in sequence to create the warped image according to the present invention. The first process maps a desired target pixel or frame spacing to an appropriate FIR filter wherein the size of the FIR filter is chosen based on the desired target pixel or frame spacing. Once the filter is chosen, a second process creates an appropriate number of upsampled pixels, lines or frames based on the input source pixels, lines or frames. The last process multiplies the correct filter coefficients from the first process with the interpolated pixels, lines or frames from the second process, resulting in correctly Nyquist bandlimited target pixels, lines or frames.

Abstract: Global-adaptive deinterlacing systems and methods for reducing scintillation and feathering artifacts. Motion adaptive deinterlacing (MADI) local motion quantization thresholds are adaptively adjusted according to the amount of global motion present in the video sequence, thereby minimizing scintillation and feathering artifacts when deinterlacing the fields. A set of global motion scenarios are defined for the purpose of classifying fields, and a number of global motion indicators are used to detect on a field-by-field basis different global motion scenarios.
