Re: Arris DSR-4460 won't authorize on unencrypted feed

We just deployed a Cobalt 9223 HD encoder and 9990 decoder for a link between our hub and a station in Alabama, where the last-mile circuit is rather flaky -- lots of dropped packets. The +RTP/ARQ option for the encoder lets the decoder request retransmission of lost packets, so unless the circuit r...

Re: Arris DSR-4460 won't authorize on unencrypted feed

So... while I was at it and since it's a nice day outside, it seemed like a good time to peak the satellite dish.

The current resident disagrees.

Re: Arris DSR-4460 won't authorize on unencrypted feed

Over the years I've found that different decoders are better for certain applications than others. We've used Tandberg / Ericsson for satellite downlinks and ASI decoders for years without too much fuss, but the 8200 is troublesome if you're trying to decode an IP stream. Upcoms (yeah, right!) have ...

Re: Arris DSR-4460 won't authorize on unencrypted feed

Well, just updated the firmware on the Sencores (they tended to disappear from Dashboard and become invisible to web browsers... nothing like having to pull and reseat cards to be able to see them). And just loaded the HD license keys... so now I have something to look forward to on Monday.

Re: Arris DSR-4460 won't authorize on unencrypted feed

Yup, we have a bunch of Sencore OpenGear IRDs that need to get HD licenses. I'm not exactly loving the prospect of paying out money to receive feeds in HD that only make air in SD. At least we're a centralcasting hub, so we use the same receivers for a bunch of stations.

Sigh.

Upgrading for the Katz HD transition? :)

Re: Weather Radar

What would be the legality of directly broadcasting the NOAA feed off the Weather Service website? From NOAA's site : The information on National Weather Service (NWS) Web pages are in the public domain, unless specifically noted otherwise, and may be used without charge for any lawful purpose so l...

Re: Weather Radar

From what I see of the WeatherTAP's license agreement, broadcasting their graphics directly would violate their terms of service in several respects. They might offer a version of their service for broadcast, but it's not obvious to me. As Gregg points out, most television stations contract with a c...

Re: Strange skills learned

That's why I almost exclusively use non-penetrating mounts these days... Cost is within a few hundred bucks of a pole, making 2 trips to the site, a backhoe and concrete truck... We can install a 3.7m dish in one long day on a ground level non-pen mount. There are tradeoffs for sure. I greatly appr...

And if you have satellite dishes, you learn to build forms and pour concrete.

Re: Laser projector and taking photo of displayed picture

In addition to using a tripod another consideration is any vibration that may be induced in the camera when snapping the shutter. The better digital cameras have image stabilization, but despite having that in my Pentax K-70 I often shoot on a tripod with wireless shutter release to get the best im...

Re: Laser projector and taking photo of displayed picture

You can ease the problem by using a camera that can operate either manually or with shutter priority: make sure that the shutter speed is slower than the frame rate -- e.g., 1/30 or 1/15 of a second. Use a tripod for stability, and pick a time when the video on the screen is not moving.

Re: BVH-2000 stuck on "INITIAL"

On the SY-80 board, take a look at capacitors C28 (22uF/25v) and C29 (1uF / 50v). They're both part of the CPU reset logic, and the purpose is to give the power supply time to come up completely and the rest of the machine to be fully powered before releasing the reset inputs to the CPUs on SY-80, S...

Re: ABC news audio alerts like NBC blackbox voice alerts

We DA ours into several "pod top" Fostex speakers (CNN's squacker too), and let the producers deal with how loud they want it. Our producers have a volume control, too. The big problem is that some of the NewsOne folks are pretty quiet, while others have overly well-developed lungs... so the proces...
