Abstract
Disclosed is a method for synchronizing video in a system including a host CPU and a plurality of transcoder instances, the method comprising: receiving, by two or more transcoder instances in the plurality of transcoder instances, a synchronization Internet Protocol (“IP”) packet from the host CPU, wherein the synchronization IP packet is received as one packet in a multicast stream of IP packets; detecting, by the two or more transcoder instances in the plurality of transcoder instances, the synchronization IP packet at the same point in the multicast stream; and transcoding, by the two or more transcoder instances in the plurality of transcoder instances, the multicast stream of IP packets immediately after detecting the synchronization IP packet.
