CA 2650869

A video signal switching system wherein existing network components and the like are used to perform a switching process, thereby reducing the costs and improving the versatility as well. As a solution, a video signal switching system is provided which comprises a plurality of input port parts that acquire non-packet digital consecutive signals; a plurality of output port parts that output the non-packet digital consecutive signals; a packetizing part that packetizes the acquired non-packet digital consecutive signals into packets after associating them with the input port identification information of the input port parts having acquired them; a switch part that distributes the packets to the output port parts in accordance with the input port identification information associated with those packets; and a restoring part that restores the packet signals distributed by the switch part to the non-packet digital consecutive signals.

L'invention concerne un système de commutation de signal vidéo dans lequel des composants réseau existants et similaires sont utilisés pour effectuer un procédé de commutation, réduisant par là les coûts et améliorant également la polyvalence. Comme solution, un système de commutation de signal vidéo est proposé, qui comprend une pluralité de parties de port d'entrée qui acquièrent des signaux consécutifs numériques non en paquets ; une pluralité de parties de port de sortie qui émettent les signaux consécutifs numériques non en paquets ; une partie de mise en paquets qui met en paquets les signaux consécutifs numériques non en paquets acquis après les avoir associés à des informations d'identification de port d'entrée des parties de port d'entrée les ayant acquis ; une partie de commutation qui distribue les paquets aux parties de port de sortie conformément aux informations d'identification de port d'entrée associées à ces paquets ; et une partie de restauration qui restaure les signaux de paquets distribués par la partie de commutation aux signaux consécutifs numériques non en paquets.
