The Advanced Television Systems Committee recently approved and published a new standard designed to enable next-generation applications of data broadcasting.
ATSC Standard A/92 "Delivery of IP Multicast Sessions over ATSC Data Broadcast," specifies the delivery of IP multicast sessions, the delivery of data for describing the characteristics of a session and usage of the ATSC A/90 Data Broadcast Standard for IP multicast-based Data Broadcast Services.
The standard defines a model where IP network terminology and concepts can be applied to the transmission of IP multicast services in an ATSC transport stream. It outlines a variety of ways for signaling an IP multicast service within the service description framework defined by the A/90 specification. Detailed usage recommendations are provided for each scenario.
The A/92 standard and other technical documents are available at www.atsc.org/standards.html
