  • Patent number: 6363125
    Abstract: According to the present invention a method and a receiver for high-frequency signals is provided. The receiver comprises a power divider (4) to divide a modulated RF input signal in at least two branches. At least one delay line (5, 6) provides for a delay of the branches relatively to each other by a predetermined delay constant. A calculation circuit (7, 8) calculates at least three power levels based on combinations (12, 13, 14) of the two branches of the input signal relatively delayed (5, 6) to each other. A processing means (10) calculates the phase and the amplitude of a complex signal representing the relation between the two branches of the input signal relatively delayed to each other, on the basis of the said at least three power levels (8). The invention therefore provides for a direct 6-port receiver based on non-coherent detection. The concept of the invention is inherently cheap and features high integration ability and low-cost processes.

  • Patent number: 6341192
    Abstract: A stream whose redundancy has been eliminated using the continuity specified particularly in the MPEG and the like, is interrupted once, and well connected to another stream. An edit point decoding method for reproducing and decoding data from a disc in which an edited MPEG stream is recorded. Before a time for output of an edit-out point is reached, a stream in a section X is decoded and scored. When an outfit time for the leading position of the section X is reached, a stream in a section Z is decoded (not output) while the decoded data from the leading position of the section X is being output. When a time for output of the edit-in point is reached, an encoded data row following the section Z is decoded and output.

  • Patent number: 6337879
    Abstract: A video data compression apparatus with which compressed video data of suitable amounts of data can be produced and in addition the time required for processing is short. An encoder control unit performs a preprocessing for compression and coding and, at the same time, produces a flatness and an intra AC as parameters indicating the difficulty of the pattern of pictures to be compressed to I pictures. A motion detector calculates a predictive error amount (ME residual) of the motion prediction. An FIFO memory delays each picture of the input video data. A host computer approximates a real difficulty data Dj indicating the difficulty of the pattern of each picture by the ME residual, flatness, and intra AC and further calculates the target amount of data Tj of the compressed video data from the approximated real difficulty data Dj. The encoder performs the compression and coding so that the amount of data of the compressed video data becomes substantially the target amount of data Tj.

  • Patent number: 6333768
    Abstract: A television system performs beam convergence in video displays. The system is implemented through one or more convergence sensors, which are exposed to two distinct convergence test patterns. The output signals from the sensors when exposed to the two convergence test patterns are used in beam convergence calculations. The convergence test patterns are selected to reduce the dynamic range requirement for an A/D converter in the television system supplied with the sensor output signals.

  • Patent number: 6324336
    Abstract: An editing system having a controller for setting reproducing speed on the basis of reproducing speed data inputted via a user interface to a desired event allows e.g., slow-playback to be set to the desired event and so further realistic image can be easily generated. Thus, an editing system capable of high-speed real-time edition and having further improved usability can be realized. Moreover, when an in point of first video data (V2) is specified, the editing system starts a reproducing operation from a position that is a fixed time before the position of the specified in point and displays thus reproduced second video data (V3) on a display (2b), so that if the specification of the in point is late, the in point can be easily corrected by monitoring the reproducing second video data. As a result, an editing system capable of high-speed real-time edition and having further improved usability can be realized.

  • Patent number: 6317807
    Abstract: A data storage apparatus has a plurality p of storage spaces for storing sets of data. Each of the spaces has: available (unused) space x1 for storage; a number x2 of data sets already stored; a number x3 of channels available for transferring data to the space; and a number x4 of times the space is scheduled to be used for reading out sets of data therefrom. An allocation factor Qp=f(ai, xi) is calculated for each space where ai are weighting factors ranking xi in order of importance. A data set is allocated to the space having the “best” (e.g. lowest) value of Qp at the time the data is to be allocated. Once allocation factors determined, then data may be allocated according to usage indices representing the ability of a space to store the data at the time of allocation.

  • Patent number: 6295087
    Abstract: The present invention enables to obtain an image of a high resolution as reasonable costs by using an adaptive interpolation circuit which is supplied by image data R, G, and B which have been subjected to a white balance adjustment in a DSP and an R-G image is combined in an internal memory. The adaptive interpolation circuit calculates correlation degrees in a vertical direction, a horizontal direction, and diagonal directions. If an interpolation is executed according to the R-G image in the direction having the greatest correlation degree, no LPF processing is executed, i.e., no resolution deterioration is caused in a direction which orthogonally intersects the aforementioned direction. That is, the adaptive interpolation circuit enables to enhance a resolution by executing an interpolation according to the correlation of the image data around a portion to be interpolated.
