Abstract:
A method is described for generating a stereoscopic video stream (101 ) comprising composite images (C), said composite images (C) comprising information about a right image (R) and a left image (I..,), wherein pixels of said right image (R) and pixels of said left image (L) are selected, and said selected pixels are entered into a composite image (C) of said stereoscopic video stream. All the pixels of said right image (R ) and all the pixels of said left image (L) are entered into different positions in said composite image (C), by leaving one of said two images unchanged and breaking up the other one into two regions (R1, R2) comprising a plurality of pixels and entering said regions into said composite image (C).
Abstract:
The invention relates to a method, an apparatus and a system for automatically managing and organizing a database of LCNs ( Logical Channel Numbers) related to radio-television programs; the method allows obtaining a hierarchic classification of the plurality of radio-Television programs on at least two levels, based on predefined logic criteria associated with a first rough numeric identification type of each channel and then, with at least one second specific type of the same channel, which may be pre-assigned during transmission or assigned in accordance with optional or manual criteria defined by the user upon reception.
Abstract:
A method is described for localizing the position of a wireless device (7) in an environment (2) comprising a wireless network (1) having at least one access point (3), wherein said method comprises the step of receiving, by said wireless device (7), a radio frequency signal (10) which is transmitted by said at least one access point (3) and which comprises basic information for connecting to said at least one access point (3), wherein said radio frequency signal (10) comprises geographic information (20) about the geographic position of at least one electronic radio frequency device (5) located in said environment (2) and not connected to said wireless network (1).
Abstract:
A video stream composed of combined video frames, and methods and systems for its generation, transmission, reception and reproduction are described; the video frames have a first resolution and comprise 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. The video frames are suitable for making, by means of a temporal sequence, a video stream comprising at least two information streams, one constituted by the video stream (F1) and the other constituted by the information stream (F2) with content independent of the previous video stream (F1).
Abstract:
The invention discloses a method of bi-directional communication in a cellular mobile telecommunication network (2), wherein a terminal ( 10) receives signals transmitted by at least one radio base station (5.7) of a downlink network of the cellular mobile telecommunication network (2) and selects one serving transmitting radio base station (6) among one or more transmitting (5) or transceiving (7) radio base stations of the downlink network, wherein the downlink network operator selects one serving receiving radio base station (8) among one or more receiving radio base stations (3,7) of an uplink network which have received a signalling message (URRA) transmitted by the terminal (10). By means of the serving receiving base station (8) of the uplink network and the serving transmitting base station (6) of the downlink network, the terminal (10) establishes bidirectional connections over the cellular mobile telecommunication network (2).
Abstract:
