Abstract: A soft trellis slicer is provided in a high definition television (HDTV) receiver. The soft trellis slicer calculates a decision value and a confidence value corresponding to a phase angle error of a signal processed by the receiver. The receiver includes an equalizer, a phase tracking loop and a trellis decoder. The equalizer provides an equalized signal to the phase tracking loop; and the phase tracking loop calculates a phase angle error for the equalized signal. The trellis decoder calculates a decision value and a confidence value. The trellis decoder provides the decision value and the confidence value to the phase tracking loop, which calculates the reliability of the phase angle error based upon the phase angle error and the decision value and the confidence value provided by the trellis decoder. The trellis decoder calculates the decision value based upon a best path metric and calculates the confidence value based upon the best path metric and a second best path metric.

Abstract: An equalizer for equalizing channel multi-path distortion includes digital filters. To improve the convergence speed and tracking ability of the equalizer while lowering noise and power consumption, the digital filters are divided into sections. Various parameters of the sections, such as step-size, shutdown and update rates can be controlled. Control of the various parameters can be realized either in software on an embedded or external processor or by dedicated hardware.

Abstract: A method for transmitting a sequence of images is provided. The method indes the steps of previously defining that the sequence of images includes a plurality of frame segments and that each of the segments includes two types of images, update frames and intermediate frames, encoding and transmitting the sequence of images and decoding the transmitted sequence of images. When an update frame is present, the step of encoding and transmitting includes the step of compressing and transmitting the update frame. When an intermediate frame is present, the step of encoding and transmitting includes the step of generating and transmitting intermediate global motion parameters describing motion between the update frame and the intermediate frame. When the compressed update frame is received, decoding the transmitted sequence of images includes the step of decompressing the compressed update frame to produce a transmitted update frame.
