Abstract: A video stream composed of combined video frames having a first resolution and include in their entirety two contents usable through extraction from the aforesaid video frame: a first content belonging to a video stream (F1) at a second resolution lower than the first resolution of the frame; and, in the area of the frame formed by the remaining pixels, at least a second content belonging to an information stream (F2) having, in the case where it is also a video stream, a resolution equal to or less than the second resolution, where during the fruition of one of the two video streams it is shown full-screen in its entirety, or in the case of a data information stream, data encoded via a set of pixels, the number of which is less than or equal to the number of pixels left free by the first video stream.

Abstract: A cooperative localization process for determining the absolute position of an apparatus to be localized includes a plurality of cooperator apparata able to cooperate, through the exchange of messages and data, in the localization of the apparatus to be localized. The cooperator apparata are equipped with at least one direct, apparatus-to-apparatus radio transmission and reception system for messages and data, and components for estimating the distance between apparata of the set of cooperator apparata. The cooperative localization apparata able to implement this process are also described.

Abstract: A system for establishing a connection between a service center and a plurality of devices for reception of a television signal, wherein the connection utilizes an electric supply network. The electric supply network is set up as a local area network (LAN) of devices for the reception of the television signal.

Abstract: A method for acquiring and storing data relating to a video stream selectable by a user through a video processing apparatus (300) includes the steps of: identifying the source of a video stream by way of at least one identification datum, the video stream having a coding and transport configuration adapted to produce a three-dimensional display; identifying the coding and transport configuration of the video stream through the acquisition of a configuration datum; establishing, by the video processing apparatus (300), an association between the at least one identification datum and the configuration datum and storing the association into storage (12) of the video processing apparatus (300) for a subsequent selection of the video stream.

Abstract: The invention relates to broadcast receivers having a voltage controlled tuning device and in particular to a circuit arrangement for applying a voltage to the tuning device. The circuit arrangement is so designed as to be capable of producing tuning voltages to tune the receiver into the desired channels but at the same time being inhibited from producing voltages which tune the receiver into undesired channels such as police channels.

Abstract: Distortion introduced into a black and white or color television signal by for example private television repeaters or boosters in the input to a television receiver, particularly amplitude compression, is compensated by a signal processing circuit which detects distortion in the horizontal part of the black and white component of the received signal and generates a correcting signal. This correcting signal controls the gain of a variable gain amplifier, through which only the part of the received television signal including line, raster or color synchronization information is fed, the complete television signal being subsequently reconstituted after compensation of the first part.
