SBE Online Presentation: All About WebRTC by Comrex

When Apple, Google, Microsoft and Mozilla team up, you might think, “Nothing good is going to come of this.” You’d be so wrong. An Open Source project is typically the last thing these tech behemoths would ever want to be involved in, let alone with their fiercest rivals. WebRTC is a fascinating example of how good things can be born of necessity and how they can foster cooperation on multiple levels. We’ll discuss the basics of WebRTC and the multitude of applications that are already using it to change the way the world communicates.  This is especially important in light of the rapid evaporation of our “traditional” telco infrastructure. We’ll also cover broadcast-specific applications and the future of live content creation.

SBE members and guests are welcome to join us online Tuesday, June 8, 2021 at 6:30 PM PDT/AZT.

Stations Should Note Reason for IPAWS April 26 RWT Failure

When FEMA issues an IPAWS test or alert, it includes a “signature certificate.” This operates similar to a password for accessing different sites or files on a computer. In the case of a message from FEMA, a message without a correct signature the EAS device should ignore the message.

On April 26, 2021, the Required Weekly Test (RWT) from IPAWS was transmitted with an incorrect signature. The test messages had a mismatch between the digest inside the message, and the digest computed by receivers. This is a part of the validation for an alert, and checking it is required by FCC Rule 11.56(c): “EAS Participants shall configure their systems to reject all CAP-formatted EAS messages that include an invalid digital signature.”
