Various embodiments of methods and systems for buffering a video stream to smooth out the variable bit rate in an MPEG 2 transport stream to a capped bit rate, while not causing packet loss on the network, and allowing the streams to pass through a bit rate constrained IP network are disclosed. One method includes conditioning a variable bit rate video content stream such that the frames are packed back to back into a constant bit rate stream such that filler packets are not required to approximate a constant bit rate. The packed video content stream, having a constant bit rate due to portions of the frames being packed into a given transmission segment, may be transmitted across a channel in a constant bit rate network.
