In accordance with an aspect of the invention, flexible burst boundaries, within an allowable range, allow statistical multiplexing to be performed in conjunction with time slicing in a digital broadcast network. The signalling of the delta-t is performed such that data of the service is not missed. Similar to deterministic multiplexing, aspects of the invention split the multiplex into several time-cycles and allocate, for each service, a time slot (data burst) from the total time-cycle according to the service's average bit rate. In accordance with aspects of the invention, however, the boundaries of each data burst are allowed to grow or shrink by a limited amount.

Time slicing and statistical multiplexing in a digital wireless network

The time until a media decoder is refreshed to produce correct output samples is minimized if an IDR picture is the first picture in a decoding order in each MPE-FEC frame. A system enabling minimization of tune-in delay is described. Aspects of the system include a content encoder for receiving a source signal including first and second bit streams and for encoding the first and second bit streams, the encoded first bit stream including a decoder refresh bit stream and the encoded second bit stream including a media bit stream. A server receives the encoded first and second bit streams and encapsulates the encoded first and second bit streams into packets. An encapsulator then receives the packets and composes a time-sliced multi-protocol encapsultation (MPE) stream by replacing a spliceable picture from the encoded second bit stream.
