The MPEG-2 Transport Stream provides a transmission network that has become widely use to support digital TV broadcast, including: DVB, DAB, ATSC, ISDB-T. These and related standards define a set of commercially available components that are increasingly being used to provide a general-purpose packet transmission network. MPEG-2 Transport networks are being used to build IP networks to supplement broadcast TV/audio services and also to provide one-way and two-way IP-only subnetworks. The BOF will explore how the IETF might work to define documents that describe the protocols required to build a complete IPv4/IPv6 unicast/multicast service, and the mappings that are needed to perform address resolution, etc. A set of Internet Drafts will be reviewed describing requirements, and some proposed protocols.
