BBC World Service Selects Ecreso FM Transmitters | Analog Cable Tv Modulator

The ideal way to build a national broadband network for access to the Internet would be with a high-bandwidth, bidirectional cable running to each individual household. But sometimes you have to work with what you’ve got, and in America, what we have are cable TV networks. These networks have the bandwidth, but not the bi-directional part—they weren’t originally intended for two-way communication. Worse, the cables for many neighbors all connect together, so it’s not possible to send a signal to just one household. And yet, cable companies manage to provide 100 Mbps bandwidth to their broadband customers using this flawed infrastructure, and they do it without compromising the preexisting cable TV service. The tech behind this magic trick goes by the name of DOCSIS, which stands for Data Over Cable Service Interface Specifications.

As an example of what might be needed in a practical system, consider eight WDM channels, each carrying 256-QAM signals between 550 and 750 MHz. In theory, without error correction, the 256-QAM signal needs a carrier-to-noise (CNR) of 35 dB to keep the error rate less than 10-9. With receiver noise and degradation due to subsequent transmission through the coaxial cable plant, assume that the lightwave system requirement is 45 dB (10-dB margin over theory). Typical demultiplexers have a minimum channel-isolation specification of -25 dB. With eight uncorrelated channels, that leads to linear crosstalk of -41 dB, which is not sufficient. The linear crosstalk from imperfect channel isolation depends only on the ratio of the powers arriving at the demultiplexer, so lowering the average optical power of the channels yields no improvement. The only way to reduce the crosstalk from this effect is to improve the channel isolation of the demultiplexer or reduce the channel count.

Sure you could go and grab a pretty decent 5″ or 7″ monitor for under $300 USD, but have a good close look at its monitoring tools and operating system. Most so-called “affordable” monitors leave a lot to be desired on this front.

I’ve shown that you lack a basic understanding of pretty much everything being discussed, and you claim a win because I misread one of your stats? That all you got?

Unlike the SRS-2, the changes observed from baseline on the Vineland-II composite and domain scores were, on average, minimal in the placebo group and were small to moderate on other scales.

Given the fact that Teradek just announced the 4K Bolt at NAB, I think it would be fair to assume that at some point tint time we will probably see a SmallHD monitor with an in-built 4K Bolt.

Also, data rates offered to individual users is not the signifiant number needed to evaluate the system, and what would be a much better indicator of system capabilities is how many concurrent 4k video streams can be supported in each direction by a satellite.

While there are still a few sector analysts and executives here and there who’ll bizarrely try to downplay one of the biggest trends in TV industry history, the numbers keep making it harder and harder to keep one’s head buried a foot below ground. Last year, for example, once again saw one of the highest defection rates of traditional TV subscribers in recent memory. According to Wall Street analysts, the top pay TV providers lost 2.5 million subscribers last year alone:
