Reviewing Technical Communications Corporation (TCCO)’s and Blonder Tongue Laboratories Inc. (NYSEAMERICAN:BDR)’s results | Digital Cable Tv Modulator

This is always a hard one to review and test. Wireless range and performance depend on where you are using it. In one location you may get 500′ of range or more, and in another, you may be lucky to get 50′. From my testing here in Japan, I found the wireless range to be pretty good. I managed to get a perfectly stable signal even when I left the transmitter in my apartment and then went down two flights of stairs, around a corner, down a corridor and then went outside the building. I was impressed as there was no direct line of sight and an awful lot of concrete and steel between the transmitter and receiver.

Instead, Moss thinks chronically cash-strapped airlines should be funneling funds into other technologies. “Right now, the thing that’s missing is ensuring the retrievability of data, and that’s where the money should go—retrievable data streams or ejectable recorders,” says Moss.

Recently at a SCTE Energy 2020 plenary discussion, a headend operations manager detailed the processes his organization used to analyze where and how often they were experiencing grid power outages, and how much generator backup time they required to offset grid downtime on a location-by-location basis. While carefully evaluating their reliance on generators, and as an adjunct consideration, how much of a power load the affected headends represented – it seemed relevant to them to consider both the cost and reliability of their generator backup systems. To maintain effective, failsafe, and sustainable power delivery, they periodically test generators to make sure they are ready to shoulder the load for their average outage time of 60 to 90 minutes. For just one multi-state region, the operations manager related that they had spent over a million dollars in 2018 just to test their generator backup systems. Merely firing the generators up periodically to ensure their functional status had cost the MSO a seven-digit number through the first eight months of 2018. According to Cisco’s total cost of ownership analysis of remote PHY vs. analog deep fiber, finding ways to reduce the baseload power requirements can greatly impact an operator’s bottom line. By reducing the power required in the headend, the access network would be more survivable during an outage and a substantial operational cost reduction could be realized.

Crosstalk arises from the WDM system components as well as the fiber itself. The multiplexer has critical performance parameters such as insertion loss and directivity but contributes negligible crosstalk. Transmission through the optical fiber generates WDM crosstalk because the fiber material has optical nonlinearities. Through the nonlinearities, the optical power of one channel can modulate the polarization, phase, or intensity of the other channels. Since cable-TV lightwave systems are intensity-modulated direct-detection systems, only intensity modulation at the output results in crosstalk. An optical nonlinearity that generates cross-intensity modulation, therefore, directly generates crosstalk. Optical nonlinearities that produce polarization or phase modulation must be accompanied by another mechanism to convert the nonlinearities to intensity modulation.

Video played a critical role in the investigation of Virgin Galactic’s SpaceShipTwo in 2014, when it broke apart over California’s Mojave Desert. On its test flight, cockpit-mounted cameras recorded—in real time—the actions of the copilot as he prematurely deployed the ship’s “feathering” mechanism, which rotates the back sections of the wings and is used to aid in reentry.

Oh I do. I run my own Plex server. But I don’t want to purchase all the content I watch. It’s not worth the cost. I can pay $14 for basically unlimited content. The stuff I really like, or isn’t available, gets purchased and ripped to Plex. Best of both worlds and I’m STILL paying less than a traditional cable package.

To check the claimed brightness of the Cine 7, I shot a white card with a light set at 5600K, and then exposed the image so it was just below 100% so there was no clipping. I then took a reading from the Cine 7 using a Sekonic C-800. The Cine 7 has a claimed maximum brightness of 1,800 nits so does it produce 1,800 nits?
