Multimedia networks in television studios are on the move from expensive special equipment to complete digitization into mainstream data networks. Differences are real-time requirements and large bandwidths of single connections. We present an algorithm to compute routes for a point to-multipoint connection within an optoelectronic switched television studio network in real-time after a connection request. This is achieved by combining offline and online algorithms. We validate the algorithm with realistic and synthetic example networks and connection requests.
