Abstract
In a content distribution system, content distribution control server, content transmission processing control method, content transmission processing control program, content transmission processing control program storage medium, content transmission device, content transmission control program, and content transmission control program storage medium, content can be reliably transmitted in accordance with the communication environment of a user terminal. A live casting server 150 of a server reservation control center 5 limits the number of streams by which the user PC 4 performs the parallel transmission of a plurality of live content at different transmission rates, in accordance with the type of circuit, which can previously prevent the user PC 4 from performing the parallel transmission of live content using the untransmittable number of streams, thus making it possible to reliably transmit the live content in accordance with the communication environment of the user PC 4.
