Abstract
(EN)
Systems and methods for distributing an audio/visual feed of a live event include mixing ambient audio signals, from ambient microphones monitoring the live event, with sound board feed from the event public address system, thereby forming a mixed audio signal. A video input signal is received at each video input in a plurality of video inputs at a video board from corresponding cameras recording the event. One such video input signal is selected as the video board output and is combined with the mixed audio signal thereby producing an audio/visual signal. This signal is encoded using a video codec, at each of several bitrates, and an audio codec, thereby forming bitrate streams each comprising the video portion of the audio/visual signal at a unique bitrate. The streams are received by a satellite router and transmitted to a satellite which sends them to one or more downlink servers for Internet distribution.

L'invention concerne des systèmes et des procédés pour distribuer une source audiovisuelle d'un évènement en direct, lesquels systèmes et procédés consistent à mélanger des signaux audio ambiants, provenant de microphones ambiants surveillant l'événement en direct, avec une source de carte son provenant du système d'adresse publique d'évènement, permettant ainsi de former un signal audio mélangé. Un signal d'entrée vidéo est reçu à chaque entrée vidéo dans une pluralité d'entrées vidéo au niveau d'une carte vidéo provenant de caméras correspondantes enregistrant l'évènement. Un tel signal d'entrée vidéo est sélectionné en tant que sortie de carte vidéo et est combiné avec le signal audio mélangé, permettant ainsi de produire un signal audiovisuel. Ce signal est codé à l'aide d'un codec vidéo, à chacun de plusieurs débits binaires, et d'un codec audio, permettant ainsi de former des flux de débit binaire comprenant chacun la partie vidéo du signal audiovisuel à un débit binaire unique. Les flux sont reçus par un routeur satellite et transmis à un satellite qui les envoie à un ou plusieurs serveurs de liaison descendante pour une distribution sur Internet.
