Problems solved by technology

[0007] However, because the device can verify the authorized broadcast area within the perimeter of the area, and then send the signal, for example, over a transmission over a longer distance network to a remote screen located in another geographical area, the device is unreliable

Embodiment Construction

[0035] In an embodiment of said invention, the audiovisual signal comprises primary content such as music extracts and / or image sequences and authorized broadcasting geographical areas marked GLI.

[0036] For example, the information includes two-character codes representing countries such as those specified in the list of country codes defined in standard ISO 3166-1:1997. This information can be simple, such as a two-character code denoting a geographic area, or complex, such as a set of several codes or a code denoting several countries, such as the code "EP" for Europe, and the code including "ES" for Spain and "IT" correspond to a different set of codes for Italy.

[0037] This authorized broadcast geographic area information GLI is added to the main content, for example by successive tapping of numbers, or preferably included in a license containing all digital rights associated with said content, to form a trial listening signal.

[0038] It should be noted that the tr...

Abstract

The invention relates to a device for presenting (6) a signal having an audio-visual content comprising means (15) for presenting said content and means (14) for connecting to a transmission channel (4) which is external with respect to said device for receiving a signal, wherein the inventive device comprises a signal transmission module (16) which is disposed in the same container together withthe presentation means (15), comprises means (20) for recording a first identification information (LLI), receives the connecting means (14) signal and transmits said signal to the presentation means(15) only when the first identification information (LLI) corresponds to a second identification information (GLI) contained in the signal. A system and method for presenting a signal comprising an audio-visual content are also disclosed.

Description

technical field [0001] The invention relates to a device, system and method for rendering a signal comprising audiovisual content. [0002] In particular, the invention relates to a device for presenting content comprising video, means for presenting this content, and means for connecting to a transmission channel external to said device for reception of signals. Background technique [0003] Audiovisual content providers restrict the broadcast of these signals to defined physical areas. For example, in some states in the United States, broadcasts of hockey games are limited to a physical area located 100 kilometers in diameter from the stadium where the game is played. [0004] For this purpose, it is known how to broadcast audiovisual signals via satellites covering divided physical areas, or to transmit authorized broadcast physical area information in video signals transmitted by cable. [0005] A storage device (for example a decoder unit) connected upstream of the re...
