Temporal compression of a digital video data stream with hierarchically searching in at least one search unit for pixels in a reference picture to find a best match for the current macroblock. This is followed by constructing a motion vector between the current macroblock and the best match macroblock in the reference picture.

Method and encoder for encoding a digital video image stream. The encoding includes spatial compression of still images in the video stream and temporal compression between the still images. The spatial compression is carried out by converting a time domain image of a macroblock to a frequency domain image of the macroblock, taking the discrete cosine transform of the frequency domain image, transforming the discrete cosine transformed macroblock image by a quantization factor, and run length encoding the quantized discrete cosine transformed macroblock image. The temporal compression is carried out by reconstructing the run length encoded, quantized, discrete cosine transformed image of the macroblock, searching for a best match macroblock, and constructing a motion vector between them. This forms a bitstream of run length encoded, quantized, discrete cosine transform macroblocks and of motion vectors. This bitstream is passed to and through an external buffer to a transmission medium.

A digital video encoder is presented adapted for dynamically switching between sets of quantizer matrix tables without pausing encoding of a stream of video data. Two or more sets of quantizer matrix tables are held at the encoder's quantization unit and compressed store interface for dynamically switching between sets of quant matrix tables at a picture boundary of the sequence of video data, i. e. , without stopping encoding of the sequence of video data. Further, while one set of matrix tables is being employed to quantize the stream of video data, the encoder can be updating or modifying another set of quantization matrix tables, again without stopping encoding of the sequence of video data.

A method to compensate for a fade in a digital video input sequence is provided where the video input sequence is to be compressed according to the MPEG-2 video compression standard. The method comprises a first step of dividing each frame of a current frame into two fields. In a second step, each field of the current frame is divided into at least one field band. In a third step, the luminance and chrominance pixel values are individually summed for the pixels in each field of the current frame. In a fourth step, the luminance pixel values are summed for the pixels in each field band of the current frame. In a fifth step, each respective field band sum and field sum of the current frame is compared with that of the previous frame in the video input sequence. In a sixth step, detection of whether or not a fade has occurred is provided, based upon the comparison in the fifth step. In a seventh step, the encoding algorithm is adjusted if a fade has occurred.

More than 2 power N external conditions are determined by a circuit package. Connections are made from N inputs to either a first or second contact at either a first or second logic state respectively or to digital outputs. The outputs may be sequentially placed at either the first or second logic state. By recording an indication signal from the inputs an electronic circuit is adapted to determine more than 2 power N conditions.

A scalable architecture MPEG2 compliant digital video encoder system having an I-frame only video encoder module with a Discrete Cosine Transform processor, a quantization unit, a variable length encoder, a FIFO buffer, and a compressed store interface, for generating an I-frame containing bitstream. For IPB bitstreams the system includes a second processor element with a reference memory interface, motion estimation and compensation capability, inverse quantization, and inverse discrete cosine transformation, and motion compensation means; and at least one third processor element motion estimation. The system can be in the form of a single integrated circuit chip, or a plurality of integrated circuit chips, that is one for each processor, the I-frame video encoder module, the second processor element, and the third processor element. There can be one or more of the third processor units.

System for reducing power consumption in MPEG-2 compliant video encoder circuitry employs logic for controlling first clock signals input to functional I, HSU and RSU blocks and functional sub-units performing specific tasks therein. Second clock signals are continuously input to a processing detection circuits requiring continuous clock inputs throughout video encode operations for a functional sub-unit. A trigger signal is asserted by the sub-unit itself or, an external processor, to indicate idle or active processing for that particular sub-unit. The combination of the second clock signals and receipt of the trigger signal enable the sub-unit to generate a sleep signal for that sub-unit which is input to a clock control circuit to either enable input of first clock signals to the functional sub-unit during active processing or, disable input of the first clock signal during idle, in-active processing periods, for as long as the trigger signal is asserted. There are a variety of video input conditions that may be detected which will enable generation of a trigger signal indicating idle processing for one or more functional sub-units, including, for example, detection of still input pictures, fade sequences and specification of high bitstream output rates.

Method, system and computer program product are provided for adaptively encoding in hardware, software or a combination thereof a sequence of video frames in real-time. A first encoding subsystem is employed to analyze the sequence of video frames to derive information on at least one characteristic thereof, such as motion statistics, non-motion statistics, scene change statistics, or scene fade statistics. The gathered information may comprise either an intraframe characteristic or an interframe characteristic. A second encoding subsystem, coupled to the first encoding subsystem, encodes the sequence of video frames employing at least one controllable parameter. The second encoding subsystem dynamically adapts intraframe or interframe encoding of the sequence of video frames by adjusting the at least one controllable parameter used in the encoding process in response to the derived information from the first encoding subsystem.
