The D2-MAC-Packet System for All Transmission Channels

J. Sabatier, D. Pommier, M. Mathieu

Based on research carried out within the European Broadcasting Union (EBU), the CCETT in France has developed a new DBS transmittal system for all channels. The D2-MAC-packet system, as it is called, joins other segments of the MAC family developed by the EBU. Its features include four simultaneously broadcast channels, improved picture quality, capability of transmittal over various cable networks, the same standard for VHF-UHF broadcasting, and no absolute limitation on bandwidth reduction. A brief summary of the various stages of the system and its characteristics is given, together with some practical results and measurements obtained in DBS, VHF, and MA TV or CA TV.
