[EAS] EAS Alerts in Tagish Yukon Canada

[media at openbroadcaster.com]

 Arthur (Father of CAP)
We currently have no plans to support H.323 or ISDN networks any time in the near future. We may consider adding support for ASN.1 BER/CER/DER decoding of CAP messages over TCP/IP if there is enough interest, and if an organization comes forward to volunteer testing and debugging time using their existing network systems. Otherwise, we do not plan to support ASN.1.

While our code is based on X.1303 framework, we only support CAP-CP implementation at this time and don't currently support the US EAS system. I tried a little while ago to get a list of NAADS urls to test with but wasn't able to find a single one because of the $%^&* amount of bureaucracy.  Call out to anyone that has this information.

One area that we have beta completed is adding support to our systems for Ravenna\AES67 AoIP. Where we are planning next is to integrate CAP alerting into AoIP, so that our systems would be "plug and play" with supported digital consoles, automatically cut in with CAP alert messages and flash console lights to DJs to indicate an emergency in progress.

Here is a recent presentation of our work http://preparecenter.org/resources/cap-workshop-2016-openbroadcaster and a new map released by CRTC that may be of interest http://crtc.gc.ca/eng/television/services/geo.htm

Huh never thought about the challenges of supporting legacy systems, too focused on the future.

>Thanks for that update on what's happening up there!  I imagine it must be a boon not having a legacy system that needs to be maintained in parallel.

>A quick technical question... When you mention ITU recommendation x.1303, does that mean you're using the ASN serialization instead of XML?  If so, I need to learn more, as I haven't found anyone with experience implementing that format yet.

>Other than that, of course, Canada has led the way in multilingual operations and I'm sure we'll be wanting to learn from you!

>Hi All,
>Today our station(s) up here participated in semi monthly testing of Canada's alerting system, supplied by The Weather Network (Pelmorex)  The alerts are distributed by TCP socket feeds on conventional internet, as well as on C Band and (2) KU Band satellite transponders.  Our regulator, CRTC made it mandatory that ALL broadcasters, as condition of licence participate in the NPAS. Broadcasters are responsible for the costs of equipment to carry the EAS feeds that are provided free of charges.

>Our commercial station, CFET 106.7 FM uses a home grown open source CAP client (built on x.1303) to relay unattended these broadcast intrusive alerts.

>Canada is a bilingual country with alerts issued in both English and French.    The issuing organization has the option of including attachments, such as WAV and JPG.  If these multimedia files are not included, or arrive corrupted then our box falls back to using a local bilingual TTS engine to "read" out the alert description.  Today's alerts were issued and transmitted as high quality Wav files with JPG attachments.

>I must say your EAS list is a very interesting resource to learn about your collective experience in the US broadcast industry and the challenges of emergency broadcasting.

>If any of you folks are up this way, shoot me a telegram and we'll get together for some fireweed tea and smoked moose nose sandwiches :-)
