Those of you who’ve followed us here at in-koherence know that we’ve taken a skeptical eye to using SSDs in DVRs, although things started to turn around a couple years ago. Still, even with improved endurance and falling prices the good old hard drive reigned supreme. While they eventually suffer mechanical failure (usually degradation of the platters) after a time, they tend not to fail just because you’ve written a certain amount of data to them. In regular use the drive will suffer mechanical failure long before then. This isn’t the case with SSDs. The NAND flash cells can only be written a given number of times, and although most employ sophisticated algorithms to optimize the wear of those flash cells, you need to pay attention to a drive’s endurance rating.
But something interesting has happened in the storage market – high endurance and somewhat affordable SSDs have started to appear – thanks to the chia cryptocurrency of all things. And a reasonably-priced high-endurance SSD is just what’s needed for DVRs.

it’s been a year a year like no other. Social distancing. Paper hoarding. DPE. Isolating ourselves to reduce spread and avoid becoming one of the afflicted. But after a year of not having to make excuses about ignoring your aunt’s friend request and finally watching that DVD you bought in 2005, there’s a ray of hope in combating STRM-NOVID-19 and a return to normalcy.

Yes we’re still alive! It’s been a crazy 2020. On top of pandemics, wildfires, and air quality bad enough to turn day into night, our WordPress installation has been plagued with issues preventing new posts from appearing. At long last it looks like we’ve exorcised the spirits haunting our site, so here’s what we’ve been up to while manually recovering posts from databases…
It’s been a busy year: ATSC 3.0 (aka NextGenTV) has moved from testing to reality and services have launched in Las Vegas, Portland, and several other locations. SiliconDust did a HDHomerun Quatro 4k Kickstarter, and after an almost comical set of delays including a dock strike and Nick Kelsey hoping for no earthquakes in Southern California, they’ve arrived in backer’s hands (including ours!). And we’ve been busy making sure Project Entangle keeps pace with these developments. Continue reading “Entangle Update Halloween Edition: Spooky Action at a (Social) Distance”
Broadcast television has traditionally been a prix fixe affair. A bunch of people shoot some video, slice it, stich it, and present it to you on your large screen TV to sit back and savor. If what appears doesn’t suit your palette, well, you can change the channel. Traditional broadcast TV has also been a largely lean back, consumptive experience without any chance to interact with or steer the program.
All that could change with ATSC 3.0 (aka NextGen TV). Continue reading “Reach Out and Touch Someone (…or your TV). Thoughts on ATSC 3.0 broadcast apps.”
