Abstract: The present invention relates to a distribution system (101; 201) for audiovisual contents, comprising at least one input interface (111) adapted to receive (801) at least one first radioelectric signal (S1) in a first frequency band, containing at least one video stream comprising at least one audiovisual content; at least one tuner (113) operatively associated with the input interface (111) and adapted to select the video stream from the first radioelectric signal (S1) in the first frequency band; at least one demultiplexer (114) operatively associated with the tuner (113) and adapted to extract an audiovisual content from the video stream; at least one IP encapsulator (116) operatively associated with the demultiplexer (114) and adapted to encapsulate the extracted audiovisual content into a packet data stream coded according to an IP protocol; at least one radiofrequency transceiver (119, 219, 319) configured to generate a second radioelectric signal (S2; S2') containing the IP data stream; and at least one coaxial interface (124, 125) for a coaxial cable (130, 131), operatively connected to the transceiver (119, 219, 319) and configured to emit the second radioelectric signal (S2; S2') on the coaxial cable (130, 131); at least one splitter (112) operatively connected to the input interface (111) and configured to receive the first radioelectric signal (S1) and split it so as to send it on one side to the coaxial interface (124, 125) and on another side to said tuner (113); at least one diplexer (121, 122) configured to receive the first radioelectric signal (S1) from the splitter (112) and send it to the coaxial interface (124, 125) for emitting a third radioelectric signal (802; 803) comprising the first radioelectric signal (S1) on the coaxial cable (130, 131) in the first frequency band, and further configured to receive the second radioelectric signal (S2; S2') from the transceiver (119, 219, 319) and send it to the coaxial interface (124, 125) for emitting the third radioelectric signal (802; 803) comprising the second radioelectric signal (S2; S2') on the coaxial cable (130, 131) in a second frequency band (816, 817; 818, 819), which is different from the first frequency band (811, 812, 813, 814, 815). The present invention also relates to an associated transceiving system ( 102, 103, 202, 203, 501) for transmission/reception of audiovisual contents in an environment.

Abstract: The present invention relates to a method for displaying a video stream according to a format defined by a user, wherein a graphic element is superimposed on the displayed video stream, and wherein the dimensions and/or position of the graphic element are modified as a function of commands received from the user, so as to define a screen area in which a certain portion of the frames of the video stream is displayed. The video stream is then displayed in a format wherein, for each frame, the frame portion defined by the graphic element is displayed with altered dimensions and/or position on the screen.
