Broadcast equipment communication protocol
View Patent ↗A data link manager includes a User Datagram Protocol (UDP) receiver for receiving HD Radio broadcast equipment communication protocol (HDP) data or non-HD Radio broadcast equipment communication protocol (non-HDP) data using a User Datagram Protocol/Internet Protocol (UDP/IP) protocol; a Transmission Control Protocol (TCP) receiver; and a router for receiving data from the UDP receiver and the TCP receiver, for searching for a destination route in a routing table, and for forwarding the data received from the from the UDP receiver and the TCP receiver to an identified destination route.
1. A data link manager comprising:
one or more hardware processors;
a User Datagram Protocol (UDP) receiver configured to receive HD Radio broadcast equipment communication protocol (HDP) data using a User Datagram Protocol/Internet Protocol (UDP/IP) protocol, wherein the UDP receiver verifies Application Frame Layer (AFL) sequence numbers for HDP frames and if the HDP frames are received out of order, the UDP receiver reorders the HDP frames;
a Transmission Control Protocol (TCP) receiver, wherein the TCP receiver receives the HDP data using Transmission Control Protocol/Internet Protocol (TCP/IP); and
a router for receiving data from the UDP receiver and the TCP receiver, for searching for a destination route in a routing table, and for forwarding the data received from the UDP receiver and the TCP receiver to an identified destination route wherein the UDP receiver, the TCP receiver, and the router are implemented by the one or more hardware processors.
2. The data link manager of claim 1 , further comprising:
a configuration database providing link and routing information.
3. The data link manager of claim 1 , wherein:
if the data received by the UDP receiver is on an HDP link, then the UDP receiver unpacks the HDP data and forwards the data to the router.
4. The data link manager of claim 1 , wherein:
the TCP receiver forwards the data to the router.
5. The data link manager of claim 1 , wherein:
if the destination route is a HDP link, then the router formats the received data according to HDP and forwards the data to the identified destination route.
6. The data link manager of claim 5 , wherein:
if the HDP link is broken due to network problem or no data activity, then the TCP receiver automatically retries to connect to another broadcast component.
7. The data link manager of claim 1 , wherein:
the router provides data activity or monitoring facility for each HDP link separately.
8. The data link manager of claim 1 , wherein:
the router provides data multicast facility to achieve one exporter communicating to multiple exgine broadcast components.
9. The data link manager of claim 1 , wherein:
if the Application Frame Layer (AFL) sequence number and an expected sequence number do not match, a difference between the Application Frame Layer (AFL) sequence number and the expected sequence number is determined and the HDP frames are reordered if the difference is less than a maximum reorder depth.
