The disclosure relates to a recording and reading apparatus constituting a kind of video reservoir in the home of the consumer. Thanks to a large-capacity storing technique with suitable technical means, broadcasters transmit numerous programs via specific channels and the consumer may control the content of his reservoir (by recording, reading and erasing programs). The invention is applicable to on-demand video in the consumer's home with a video reservoir constituting a video-library that is regularly updated by broadcasters and/or by the consumer himself.

Videotext data or data transmitted through a telephone network is displayed by: receiving and decoding the data by a receiver/decoder device disposed in a television receiver, a video cassette recorder, or connected to the television receiver or the video cassette recorder; transmitting the data from the television receiver or the video cassette recorder to a control device for the television receiver or the video cassette recorder; and, receiving and displaying the data on a display device of the control device. The data may be displayed on a tactile sensitive screen of the control device, for example liquid crystal or plasma displays. The television receiver or the video cassette recorder may be programmed responsive to tactile stimulation of the screen.

Method and apparatus for processing and displaying videotext or

A receiver/recorder for television transmissions whereby continuous recording of television transmission occurs from at least one channel onto a random-access rewritable recording medium. At each of a plurality of predetermined locations a binary code is periodically written to represent a filling of predetermined portions corresponding respectively to the predetermined locations. An indexing device responds to the binary code in order to automatically distinguish between a first in time recorded transmission on the medium from a second in time recorded transmission on the medium at a particular one of the predetermined locations.

Receiver/recorder of television transmissions

Method for automatic programming of a tuner and device for

A receiver/recorder of television transmissions is disclosed which operates automatically on a stand-by basis to record continuously television transmissions from at least one channel onto a reusable large capacity recording medium such as a magnetooptic disk. The recording is accomplished without user intervention and the system includes an indexing for distinguishing a recent recording from an older recording which is partially overlapped by the recent recording.

Continuous television transmission reproduction and playback

Television receiver with deferred transmission of moving image sequences

A device for the display or projection of images, which has an external output face covered with an abrasion-resistant and transparent coating, said coating constituted in part of an abrasion-resistant layer formed from at least one material selected from the group consisting of adamantane carbon, Y.sub.2 O.sub.3, and indium-tin oxide implanted with oxygen. A display or projection device can be a television tube designed for the display of high-definition transmissions.

Device for the display or projection of images or similar information

The diaphragm comprises at least one chamber in which there flows a deformable material that attenuates the radiation beam, the chamber being shaped so that the attenuating material can be introduced from outside the chamber and so that it can surround the passage zone of the beam inside the chamber in such a way that the surface of the passage zone varies constantly with the volume of the material present in the chamber.

Diaphragm for electromagnet radiation beam and its use in a collimation

The device can be used for the displacement of light lines above determined zones of a surface and for the optical identification of these zones. It comprises one or more lateral diffusion light guides arranged parallel to the surface, coupled by one end to a light source and to controlling means in order to selectively illuminate each zone of the surface by means of at least one light guide.
