Title (EN) VIDEO AND AUDIO INTERFACE FOR A COMPUTER
(FR) INTERFACE VIDEO ET AUDIO POUR ORDINATEUR
Abstract:
(EN) An advanced video and audio interface for a computer is disclosed. The interface comprises an interface device and an interface cable. A system employing the interface comprises a host device, a remote device, and the interface cable disposed between the host device and the remote device so as to communicate data from the remote device to the host device and instructions from the host device to the remote device. The remote device is capable of transmitting data over the interface to the host device and comprises the interface device, a video data scaling device, a video data compression device, an audio data analog to digital converter, and an audio data compression device. The host device is capable of transmitting data over the interface to the remote device and of selectively configuring each of the video data scaling device and the video data compression device over the interface.
(FR) L'invention porte sur une interface vidéo et audio perfectionnée pour ordinateur comprenant un dispositif interface et un câble interface, et sur un système utilisant ladite interface et comportant un dispositif hôte, un dispositif à distance et un câble interface placé entre le dispositif hôte et le dispositif à distance pour transmettre des données du dispositif à distance au dispositif hôte, et des instructions du dispositif hôte au dispositif à distance. Le dispositif à distance, qui peut transmettre des données au dispositif hôte via l'interface, comporte le dispositif interface, un dispositif de mise à l'échelle des données vidéo, un dispositif de compression des données vidéo, un convertisseur A/N des données audio et un dispositif de compression des données audio. Le dispositif hôte est capable de transmettre des données au dispositif hôte via l'interface, et de configurer sélectivement via l'interface le dispositif de mise à l'échelle des données vidéo et le dispositif de compression des données vidéo.
