Apparatuses and techniques for dynamic credit control in the context of a multi-traffic class communication system are described. Dynamic credit control is provided through the use of central-controlled, traffic class receiver buffers for multiple traffic classes. The size of the traffic class receiver buffers can be modified on-the-fly, during operation of the system. This provides a high degree of flexibility, particularly in the context of heavy traffic class packet traffic which, in turn, greatly facilitates operation of today's advanced applications.

Dynamic credit control in multi-traffic class communication system

A multi-directional comb filtering in a digital video decoder is provided. Some embodiments of the present invention provide for a method of filtering, using a multi-directional comb filter, pixel data from a sequence of fields of pixel data, wherein the fields of pixel data comprise a previous field, a current field and a next field, and wherein each of said fields includes a previous line, a current line, a next line.

Multi-directional comb filtering in a digital video decoder

A multi-directional comb filtering in a digital video decoder is provided.

An adaptive gain and offset control for a digital video analog to digital converter is provided. A gain indicator and/or an offset indicator, which are used as inputs control signals to an analog-to-digital converter, are determined based on a detected maximum level and a detected blanking level from an input video signal. The gain and offset indicators may be determined independently from a minimum level of the video signal.

Adaptive gain and offset control in a digital video decoder

In one example, a digital video resampler and decoder is disclosed. An input buffer is coupled to a source of a video signal oversampled by at least two times. A horizontal synchronization detector is coupled to the input buffer, and detects horizontal synchronization boundaries. A counter is coupled to the horizontal synchronization detector to count a number of samples between horizontal synchronization boundaries. A comparator is coupled to the counter and compares the counted number of samples to a reference count. A sample corrector is coupled to the input buffer and modifies a block of samples based on a result from the comparator. An output buffer is coupled to the sample corrector to hold the modified block of samples. A comb filter is coupled to the output buffer, and generates first and second three-dimensional color values based on the modified block of samples.

Digital timing extraction and recovery in a digital video decoder

A digital video decoder architecture is provided wherein chrominance values are determined first, then luminance values are determined, in part, based on the previously determined chrominance values. In this architecture, luminance separation occurs after and based on one or more chrominance values.
