Patent CA-2052589-C (CA)
Title: Rate conversion apparatus
Inventor: ICHIYOSHI OSAMU
IPC: H04L25/05
Filed: 1991-10-04
Granted: 1997-12-23
Abstract: A first clock signal of f1 in frequency is converted into a second clock signal having a frequency of f2 = ~ f1.          The first clock signal is converted by a tank circuit (12) and a converter (13) into an R-bit first phase signal (~1) indicating the phase of the first clock signal.  The first phase signal is multiplied by n (mod 2R) by a multiplier into a second phase signal (~3).  The second phase signal is supplied to a digital phase-locked loop (PIL)  (3) consisting of a subtractor (15), a low-pass filter (LPF) (16), a numerically controlled oscillator (NCO)  (17) and a multiplier (18).  The multiplier in the digital PIL (3) multiplies by m (mod 2R) a third phase signal, indicating the phase of a second clock signal which is the output of the NCO (17), to generate a fourth phase signal.  The subtractor (15) generates a signal representing the phase error between the second and fourth phase signals.  This phase error signal is filtered by the LPF (16) to control the oscillating phase of the NCO (17).  A clock generating circuit generates, on the basis of the third phase signal, the second clock signal.

As a result, more consistent output is provided, as well as improved system efficiency and ability to accommodate for varying operational conditions and wear.
Patent CA-2055831-C (CA)
Title: Adaptive filter and a method of preventing divergent behavior of the adaptive filter
Inventor: IWASAKI MOTOYA
IPC: H03H21/00
Filed: 1991-11-19
Granted: 1995-05-30
Abstract: A method of preventing divergent behavior of a recursively adjusted adaptive filter and an adaptive filter to which the method is applied are disclosed.  The adaptive filter is adjusted by alternately carrying out two kinds of corrections during respective correction terms.  In the first correction term, each tap gain in the adaptive filter is corrected through a recursive correction algorithm.  In the second correction term, a new tap gain is produced by multiplying the current tap gain by a constant which is predetermined so as to suppress divergent tendency in recursively corrected values of each tap gain.  Therefore, operations to make recursively corrected values of each tap gain converge and operations to suppress divergent tendencies in the recursively corrected values of each tap gain are executed alternately.

Inventor: ISHIHARA SHINGO
IPC: G06F9/38
Filed: 1992-05-29
Granted: 1997-10-07
Abstract: The data words in a list are grouped into n groups.          The grouping is performed by selecting the first data word of the list and every nth data word thereafter to form a first group, and then by selecting the next data word of the list and every nth data word thereafter to form a second group and repeating this selection process until n groups are formed.          The maximum/minimum among the data words of each of the n groups is determined, and a data word number of the maximum/minimum is ascertained.  Subsequently, an absolute data word number of the maximum/minimum of each of said n groups is determined using the data word number obtained and the group number and n.  Finally, the absolute data word is determined by ascertaining the maximum/minimum in the list by comparing the n maximums/minimums of the n groups.

Title: Converting lines to other colors
Inventor: BOLLMAN JAMES E
IPC: H04N1/62
Filed: 1992-09-01
Granted: 1997-03-18
Abstract: A method for varying the color of an image including lines and background. Where the image includes the colors black and white and a plurality of gray pixels, where gray refers to the presence of pixel values between the maximum and minimum pixel values, inclusive, the image is first converted to a color space, such as for example, r, g, b (red-green-blue).Pixel values are thresholded for differentiation between lines and background. When pixels have a value indicating that the pixel is back-ground, that pixel is set to a background color that has been previously selected. Otherwise, that pixel is set to a foreground color. The result is that background is set to a single color, and lines are set to a second color. Alternatively, where intermediate values are present, the foreground color value may be added to the intermediate level color value to produce a gradually varying colored line.

Title: Apparatus and method for displaying recorded compressed digital high definition video information
Inventor: KNAUER SCOTT CARROLL
IPC: H04N19/50
Filed: 1993-01-04
Granted: 1999-02-16
Abstract: An apparatus provides digital data representative of a compressed high definition video image signal in a manner such that a conventional video tape recorder (VTR) employing current electrical and mechanical technologies is adaptable for reading this data for display in special modes such as fast forward, reverse and still frame. To minimize the loss of data while the VTR is operating in one of these special modes, the data representative of the high definition imagesignal is decoded by the apparatus to yield available time slots in the data stream. These time slots are then filled with data which duplicates the most important of the original transmitted data then existing in other time slots in the data stream. This duplicating of the data increases the likelihood that the important picture information will be read by the VTR while operating in a special mode. To facilitate fast recovery from lost of synchronization, the apparatus utilizes a small fraction of the original image which is included in each section or slice of the transmitted image. As synchronization is reacquired, the high definition video image is built from the image found in the slices.
