Development of advanced HD-MAC coding algorithms

Among the different subprojects of the Eureka 95 HDTV project, subproject 5 has been given the task of formulating the detailed algorithm to be used for coding the HDTV signal into a MAC compatible form to be submitted to the CCIR. The authors describe the organization of the working group within subproject 5, the separation of the problem into its various aspects and the contributions being made by the participating organizations. The main lines of investigations to improve the HD-MAC performances are reported as well as the various options of coding system to which these investigations have given birth, and have been worked out as ´candidate system´ by several companies. The procedure used to operate the selection for the final system is reported.<>
