A versatile multiplexing algorithm exclusively based on the MPEG-2 systems layer

Abstract

This work introduces an algorithm to multiplex stored MPEG-2 PES streams into one SPTS regardless of the PES streams type or bitrate. The algorithm is devised to comply with the MPEG2 standard STD. In order to support all available levels and profiles, the STD buffer lengths are parametrized and a maximum output bitrate can be established. To check the validity of the algorithm, a simulator has been implemented in a high level functional language. To prove its usefulness, a MPEG-2 PS to TS converter was implemented in C using this algorithm. The paper focuses on the algorithm description and shows some results obtained with the simulator.
