A METHOD AND SYSTEM FOR ANNOUNCING A IP BASED SERVICE IN A TRANSMISSION STREAM

摘要

A method for discovering service announcements for IP based services in MPEG-2 Transport Stream using PSI tables. These service announcements contain the mapping of IP based services into physical and link layer parameters and description of content. With the method described in these embodiments, the receiver can automatically discover all the IP based services existing in the TS described in SA without requiring any use of the interaction network. Also only a few configuration is required in the transmission network in order to provide full access to all available broadcast IP based services.
