Abstract: In an apparatus for converting received video signals of a first format, which has a first number of horizontal lines in a field or frame and a picture display of a first aspect ratio, to video signals of a second format, which has a second number of horizontal lines in a field or frame and a picture display of a second aspect ratio: an analog-to-digital converter (2) converts the received video signals of the first format to digital video signals, a memory (6) has addresses at which there are written at least a field of the digital video signals of the first format, whereupon, a reading circuit (7) reads from the memory (6) addresses less samples of the digital video signals than were written in the memory (6) and the digital video signals thus read from the memory (6) are converted back to analog form, and a controller (9 ) is provided for variably determining a start address of the addresses in the memory (6) from which video signal data are read. In the case where the first aspect ratio is larger than the second aspect ratio, the selection of the start address determines a portion or portions of the picture display of the first aspect ratio to be omitted at least at one side of the picture display of the second aspect ratio.

Abstract: A side pincushion distortion correction circuit has an impedance circuit connected in series with the deflection coil in a television receiver. A controllable switch connected in parallel with the impedance circuit is operated by a switching signal, the phase of which is modulated by a combination of a parabolic signal at the vertical rate and a control signal corresponding to the brightness of a reproduced picture on the screen of the television receiver in order to maintain proper correction of side pincushion distortion despite variations in the brightness of a picture reproduced on the cathode ray tube of the television receiver.

Abstract: To provide a television interphone system designed to solve the problem of difficulty in adequately recognizing a visitor because of restriction of the visual field in the vertical direction due to the size of the picture frame sideways long. If the aspect ratio of the image receiving size of an image input section of a slave unit is about 3:4, a corresponding display is made by converting the aspect ratio of a monitor section of a master unit into 1:1. By this display method, problems relating to recognition of a visitor outdoors primarily needed with respect to a television interphone system, such as a problem of a little child visitor short in height being out of the visual field, and a problem in confirming whether a visitor is doing something suspicious or holding a dangerous thing, can be effectively solved.

Abstract: PROBLEM TO BE SOLVED: To enable an aspect ratio of a display screen to be arbitrarily set as required and correspondence to various video devices with a single cathode- ray tube by forming a fluorescent face so that the aspect ratio is substantially equal in a cathode ray tube. SOLUTION: In a flat cathode-ray tube 16, a face plate 16A is formed lengthwise, and further a fluorescent face 20 is formed so that an aspect ratio is 1:1 viewed from the face plate 16A side. That is, with respect to the fluorescent face 20 viewed from the face plate 16A side, when a screen size specified by a length of a diagonal line is G, in a fluorescent face with an aspect ratio of 3:4, horizontal and vertical lengths are 0.8G and 0.6G, respectively, and on the contrary in this flat cathode-ray tube 16 the horizontal and vertical lengths are 0.8G, respectively. Thereby, in the flat cathode-ray tube 16, an aspect ratio of a display image can be arbitrarily set.

Abstract: The horizontal deflection apparatus has a separator the cross-section of which takes a saddle-shape form, and horizontal deflecting coils are comprised of three coil groups connected in a series to each other. The first coil group is wound on the outermost circumference on the inside of the main structure of the separator, the second coil group is wound at a predetermined distance from the first coil group, and the third coil group is wound at a predetermined distance from the second coil group. Deflecting efficiency at the deflection center is improved because the deflection magnetic field generated from the second and third coil groups is generated at the deflection center.

Abstract: The beam forming means and static convergence correcting means in a color cathode ray tube are arranged to provide for proper convergence of the beams at regions remote from the center of the screen and closer to the corners. The resulting misconvergence at the center of the screen is then corrected by dynamic convergence correcting means which produces less beam distortion then if it had to correct misconvergence at the corners.
