Abstract
A Headend system including a video codec to encode a video sequence yielding an encoded video sequence having video packets, a multiplexer, a signal generator to receive a notification of a splice point, analyze at least some of the encoded video packets based on the notification in order to find a random-access-point-packet, the random-access-point being a point from which to start decoding the encoded video sequence by the rendering device so that the video sequence may be rendered for output from the splice point, create a timing signal estimating a location of the random-access-point-packet in the encoded video sequence, and output the timing signal to the multiplexer or transmission equipment. Related apparatus and methods are also described.
