The Project Entangle EX-β

The Entangle EX-ɤ

A couple months ago we were thrilled to assemble an Entangle platform that actually looked and felt more like a set-top box. The Entangle EX-α is a Raspberry Pi 4 mated to an HDHomerun Flex 4k. Unfortunately stock FFmpeg doesn’t enable hardware-accelerated HEVC decode, which is needed to watch ATSC 3.0 broadcasts. And while patches have been done in distros such as LibreELEC, we don’t have the time at the moment to integrate those into the Entangle code base. Continue reading “The Project Entangle EX-β”

Send In The Clones! Cloning the Silver Sensor

The Zenith Silver Sensor.

For many years one of our favorite antennas, and our go-to antenna for on-the-road OTA, was the venerable Silver Sensor. It’s on the compact side and has an interesting reception pattern – it’s somewhat directional and rejects signals from the back, but has a rather wide reception from the front.  We had one since the early 2000s and for a time it was even mast-mounted outdoors, serving as a household main antenna for a DIRECTV TiVo HR10-250 beta unit. More recently its been on trips throughout California, Nevada and Arizona to tangle with ATSC 3.0 emissions.

The Project Entangle EX

 

Project Entangle – our platform for exploring ways of obtaining and consuming media – was developed on PCs and up until now Entangle platforms have largely been laptops or NUCs. They make great development environments and have a plethora of tools often missing from embedded platforms. But even “thin and light” laptops are big and power-hungry compared to most set-top boxes, and, we’ve always kept an eye out for ways we might piece together a more compact version. And we finally took our first step in that direction with a Raspberry Pi 4 and HDHomerun Flex 4k packaged in a DeskPi Pro chassis.

Koherence’s response to FCC Docket 16-142 and ATSC 3.0 DRM

As broadcasters have started turning on DRM for their services, viewers using HDHomeruns and other devices have started to lose access to those services. Here in the SF Bay Area, CBS, NBC, and Univision stations have encrypted their services while ABC, FOX, and the independent KRON remain in the clear. On a recent trip to Honolulu we also noted a number services have flipped the protection switch since our previous trip in February. As a result we have switched back to the ATSC 1.0 versions of these services, where we an record, watch, trick play, and stream throughout and outside the home via Project Entangle. (We are pleased that to date ABC has resisted the urge to protect their 3.0 service and enjoy ABC Nightly News via KGO’s 3.0 service.)

In response to the frustrations of losing access to protected 3.0 services, Lon Seidman started a change.org petition urging the FCC to take action and prevent broadcasters from encrypting their services. Readers of this blog know that we do not view protection of 3.0 services favorably – in particular services which are comparable to existing free and in-the-clear ATSC 1.0 services (which is at present basically all 3.0 services). There is a place for DRM in ATSC 3.0, and Evoca’s service was a great example.

If you haven’t signed the change.org petition, we urge you to do so. It can be found at:

Lon Seidman also filed a complaint with the FCC. In their reply the FCC provided a way for consumers to share their experiences and how they are harmed by ATSC 3.0 DRM. We encourage you to submit a comment via

NextGen Fresno!

Three exciting events have recently occurred in the normally sleepy region of Fresno, California. First, Cocola Broadcasting brought an RF 6 ATSC 3.0 “Frankenstation” on line. With UHD content! Second Sinclair launched its emission. Third, the temperature in mid-June was unseasonably cool for a couple days (highs in 70s). With that confluence of events we just had to trek out and see what NextGen Fresno had to offer!
