<p>A method and an apparatus for distributing a content stream from a headend to a subscriber terminal are described. In one example, the content stream is processed at the headend to generate a sequence of instances having successively staggered reference frames. A request for the content streams is received from the subscriber terminal at an initial time. In response to the request, an instance from the sequence of instances having the first reference frame after the initial time is selected. The selected instance is transmitted towards the subscriber terminal.</p> |
