Assignee:

General Electric Company - Princeton NJ

International Classification:

H04N 700
H04N 1100

US Classification:

358 12

Abstract:

A widescreen television signal having left side, right side and center panel information is converted into a signal compatible with a standard television system, such as NTSC. In the compatible signal, center panel information is expanded to occupy the standard display region seen by a viewer, side panel low frequency information is compressed into the horizontal overscan region, and side panel high frequency information modulates an alternative subcarrier other than the chrominance subcarrier.

International Classification:

H04N 967

US Classification:

358 30

Abstract:

The present application discloses a video signal processing apparatus for minimizing cross-color and cross-luminance interference in a composite video signal. A first filter is coupled to a color difference signal input terminal and generates a signal occupying a first region of a predetermined spatio-temporal frequency space. A second filter is coupled to a brightness signal input terminal and generates a signal occupying a second region of the predetermined spatio-temporal frequency space exclusive of the first region. An encoder forms a composite video signal from the filtered color difference and brightness signals such that they occupy mutually exclusive spatio-temporal frequency spaces. A television receiver for decoding the composite video signal is described which comprises the serial connection of a vertical-temporal filter and a horizontal filter. Filters are also disclosed for the first and second filters described above which are the serial connection of vertical-temporal filters and a horizontal filter.

Assignee:

RCA Licensing Corporation - Princeton NJ

International Classification:

H04N 5208

US Classification:

358166

Abstract:

A video signal processing system includes a signal interpolator associated with time compression/expansion apparatus. The interpolator is preceded by a high frequency peaking network which responds to a variable control signal representative of a desired amount of displayed image sharpness. In a disclosed embodiment the peaking network responds to a control signal which is a function of a distance between image pixels, and a variable signal from a viewer adjustable image sharpness control.

International Classification:

H04N 506

US Classification:

358150

Abstract:

A television sync signal generator adapted for ready conversion among various television standards includes a memory in which information related to the amplitude of at least one component of a composite sync signal is stored at address locations each corresponding to at least one particular time in each recurrent television frame. A clock signal generator addresses the memory to sequentially read out the information so the sync signal can be reconstructed. For reducing the number of memory addresses required, each memory address contains information relating to the instantaneous resolution or clock rate. A sample rate controller is coupled to the memory for having the instantaneous clock address rate controlled in response to the contents of the memory.

Assignee:

General Electric Company - Princeton NJ

International Classification:

H04N 1100

US Classification:

358 12

Abstract:

A widescreen television signal containing center panel information and time compressed side panel information in an overscan region is intraframe processed above a given frequency only with respect to the center panel information. The intraframe processing apparatus includes a signal delay network with first and second 262H delay elements coupled between an input and an output of the delay network. During a first field interval, signals from the delay input and from an intermediate point between the delay elements are subtractively combined to produce a difference term which is coupled to a signal path. During a second field interval, signals from the delay output and from the intermediate point are subtractively combined to produce a difference term which is coupled to the signal path. An intraframe processed output signal is produced by combining the difference terms from the signal path with a signal from the intermediate delay point. A filter and an electronic gate in the signal path determine frequency selective intraframe processing of the center panel information alone.

Assignee:

Combustion Engineering, Inc. - Windsor CT

International Classification:

E04B 138
F23M 500

US Classification:

52509

Abstract:

A system for insulating the walls of furnaces and other heated structures with ceramic fiber insulation including an improved insulation anchor. The anchor includes a pin which is attached to the furnace wall such as by stud welding with the pin having an elongated aperture at its outer end. A retaining rod extends through the aperture and into the adjacent ceramic fiber modules. The rectangular shaped rod includes an improved means for locking the rod in the aperture which comprises a crimp at about the midpoint of the rod. This provides a narrow section of the rod which permits the rod to be turned in the aperture and locked. The crimp method of forming the narrow section does not remove any metal from the rod and does not weaken the rod.

International Classification:

H04N 502

US Classification:

358140

Abstract:

Graphics for television display which emphasize circles, ellipses, circular or elliptical arcs, and the radii of circles or ellipses are conveniently stored in image memories addressable in polar coordinates. Television images which are to be rotated are conveniently stored in such memories, so the angular coordinate of the image memory addresses can be incremented or decremented to rotate the image with hardware as simple as a single adder. To read image memories addressed in polar coordinates, the Cartesian coordinates descriptive of television raster display are scan-converted to polar coordinates. This scan conversion takes place in real time at video sampling rates. The generation of the angular coordinate of the polar coordinates is facilitated by dividing one Cartesian coordinate by another by differentially combining their logarithms as found from read-only-memory table look-up, then finding an arc tangent from the logarithm of their difference as found from further read-only-memory table look-up. Since the non-linearities of the logarithm and arc tangent functions tend to track each other to a degree, combining the anti-logarithm and arc tangent look-up steps in a single read-only memory provides greater angular resolution for number of bits used in the read-only-memory input addresses.

Abstract:

A system for expanding/compressing a video signal includes a dual-port memory having read and write address inputs and a video signal input. A pixel counter provides a pixel location signal to the write address input of the dual-port memory, and to a programmed memory device (e. g. , a PROM) including a look-up table. The memory device is programmed to provide a time expanded/compressed version of the pixel location signal in accordance with a programmed time expansion/compression factor, which is applied to the read address input of the dual-port memory. A time expanded/compressed video signal is developed at the output of the dual-port memory.
