- US 2014/0156791 and US 2009/0141894 discuss this subject.
- a wireless connection between the source equipment and the display equipment is preferable.
- visual content here means text, image and / or video documents, optionally accompanied by audio content.
- any interruption or failure of the wireless connection may interrupt the dissemination of content .
- Display equipment such as televisions and video projectors are generally not equipped with a buffer and associated software that is sufficient to maintain the continuity of the broadcast in case of interruption of the wireless connection.
- Systems such as equipment known under the trade name "Chromecast" broadcast content using a third party wireless network (Wifi). Such systems therefore have the aforementioned defects.
- the use of a third-party wireless network to exchange content data poses security problems that remain a barrier to use in a business context, especially when the user must use a wireless LAN. for which he can not check the security level.
- this type of system requires a permanent power supply.
- Devices including an internal memory on which the contents to be broadcast are stored are intended to be physically connected to the display equipment. Such devices can sometimes be controlled remotely, for example by means of a remote control via an infrared receiver. No data is transmitted wirelessly from such a device. Such devices are generally bulky and therefore poorly adapted to mobility lilies must be powered by an external power source (sector or via USB). In addition, such devices are provided primarily for broadcasting videos and not text documents or still images. Generally lacking an operating system, updating of software components is impossible, which prevents compatibility with file formats that were not initially planned. The data that is stored on such devices must be stored in clear (unencrypted) to be broadcast at will via a display equipment to which the device is connected. In case of loss or theft of the device, the confidentiality of the data is compromised.

- the broadcast remains controllable by a remote device (not physically connected to the device).
- the content data is present on the storage device in a decrypted state only during their own broadcast and briefly upon receipt.
- the data is stored in encrypted form the rest of the time, including while streaming other content. Encryption and on-the-fly decryption of data can be made automatic, so that data remains secure without user-specific action.

- the device is scalable.
- the device further comprises a biometric sensor.
- the processing unit is further arranged to implement an authentication step via the biometric sensor, the result of the authentication step conditioning the implementation of the step of decryption of the data recorded on the device. The security of the stored data is thus improved, in particular in case of loss or theft of the device.
