Title
(EN) MIXER TO TRANSMIT AUDIOVISUAL DATA
(FR) MÉLANGEUR POUR TRANSMETTRE DES DONNÉES AUDIOVISUELLES
Abstract
(EN)
A mixer (110) can be connected to the computing system. The mixer can include a first input (115) to receive audiovisual data on a first channel from a content provider and a second input (120) to receive computer data. The mixer can transmit through an output (130) the audiovisual data received on the first channel and the computer data received from the second input on a second channel assigned by the mixer.
(FR)
La présente invention concerne un mélangeur (110) qui peut être connecté au système informatique. Le mélangeur peut comprendre une première entrée (115) pour recevoir sur un premier canal des données audiovisuelles provenant d'un fournisseur de contenu et une seconde entrée (120) pour recevoir des données informatiques. Le mélangeur peut transmettre par l'intermédiaire d'une sortie (130) les données audiovisuelles reçues sur le premier canal et les données informatiques reçues depuis la seconde entrée sur un second canal attribué par le mélangeur.
