    摘要： Evaluating coded video by identifying spatial and temporal errors in the reconstructed video. Spatial errors may be identified by evaluating the severity of each individual error and pooling closely located errors to determine whether the collection of errors is noticeable. Temporal errors may be identified by evaluating the quality of each frame and then pooling consecutive frames to determine whether the collection of frames has errors that may be noticeable if the errors persist within the sequence of consecutive frames. The quality of the frames may be analyzed with any conventional analysis metric. In an embodiment, the quality of the frames may be analyzed using a row-column metric. The calculated analysis metrics may be normalized to accurately compare different metric calculations.

    摘要： A system, method and computer program product provide finer rate control in data compression by processing a data stream through a plurality of parallel subbands, wherein a first subband processes the data differently than a second subband. Separate shift quantization parameters for each separate run-of-zeros compressed storage area or pile can be provided, instead of a single common shift parameter for every coefficient as in the prior art. The parameter value for each such area or pile can be recorded in the compressed output file. The separate shift quantization parameters can also be adjusted dynamically as data is being compressed.

    摘要： A system and method are provided for compressing data. In use, luminescence data of a frame is updated at a first predetermined rate, while chrominance data of the frame is updated at a second predetermined rate that is less than the first predetermined rate. Moreover, pause information may be inserted with the compressed data, where the pause information may be used when the video data is paused during the playback thereof to increase the quality of a still frame.

    摘要： A personal object or obstacle detector apparatus comprises a continuous transmission frequency modulation (CTFM) ranging system and an audio output device. The CTFM ranging system transmits a frequency-swept pressure wave, receives a reflected frequency-swept pressure wave from at least one object, and forms an audio signal based upon a frequency difference between the frequency-swept pressure wave and the reflected frequency-swept pressure wave the audio signal having an amplitude dependent upon size of the object. The audio output device produces an acoustic pressure wave in dependence upon the audio signal. In a preferred embodiment, the acoustic pressure wave contains separate tones for each of the objects detected, wherein each tone has a pitch dependent upon the distance from the CTFM ranging system to the corresponding object. Another embodiment utilizes a pair of CTFM ranging systems to produce a stereo auditory map of objects and obstacles.

    摘要： Methods and systems for determining a position and an orientation utilize a radio frequency signal transmitted from an effective source location which moves along a first closed, non-planar path. The closed, non-planar path has a plurality of local extreme points with respect to a predetermined axis. The radio frequency signal is received at an effective receiving location which may, optionally, move along a second closed, non-planar path. A phase signal representative of the phase of the received radio frequency signal is detected. The phase signal is filtered and processed to form at least one signal quantity representative of elevation, bearing, and/or orientation.

    摘要： A stream of time-ordered data, such as a movie, is divided into multiple fragments of equal length, which are repetitively transmitted at different respective repetition rates. The fragments are reordered for transmission so that those which occur near the beginning of the original data stream are transmitted more frequently than those which occur later in the data stream. When a user enters a request to utilize the data, the individual fragments are stored upon receipt at the user's premises, and reassembled into a contiguous stream. The ordering of the fragments is such that the wait time required before utilization of the data can begin is limited to a predetermined maximum, and at least one copy of every fragment becomes available by the time it is needed.
