ININ is retardedly expensive but I don't think its like Cisco or Avaya expensive and ININ has insane customization potential.

BangersInMyKnickers posted:ATSC is going to be kinda ownage because its going to an IP multicast carrier with h.265 data and so the number of channels/audio carriers/whatever you want to jam in your frequency band is exclusively dictated by the amount of bandwidth and what resolution/bitrate you chose to broadcast in. so you could do like 4 1080p channels, or 1 UHD channel and maybe 1 additional SD channel, or 16 SD channels, or whatever other combo inbetween you can dream up everything does this already it's why the channels look worse when they squeeze more in since they've started to run out of bandwidth they have started to lower the error correction too e:F;B ~Coxy fucked around with this message at 07:06 on Jan 9, 2016 |

I bought a car that came with a trial sub, after a month I was convinced never to pay for it. then the trial sub stayed on for the two years I had the car  half of the channels could be replaced with a good playlist for what it's worth

Beeftweeter posted:it cant possibly sound worse than sirius/xm uk digital radio and us satellite radio end up with most channels using the same amount of quality, and it's real bad most uk digital radio stations use 128 kbps MP2 when you really need like 192 or 256 for cd quality. most sirius/xm music channels get 40 to 64 kbps channels but since they're using he-aac it's about on par with the 128 kbps british radio in the old days sirius used some weird proprietary format that was worse than the he-aac format, although they did have slightly more bandwidth for each channel in comparison, US/Canada "hd radio" format uses a he-aac derived codec at 40 or 60 kbps for AM digital radio, and 125-150 kbps signal on FM. and if you listen, you'll notice that they usually have one high bandwidth subchannel simulcasting the analog, and then a lower bandwidth signal or two for simulcasting an am station or a different audio program. a station can also go full digital and have 300 kbps to play with, but there's like 2 of those across the continent. you could get like 3 really nice quality simultaneous music channels or a single 5.1 surrpund channel out of that. also many of the ones that operate in analog-digital mode just have a single really high bandwidth signal for the simulcast.

Awia posted:who listens to the radio tho? In my country, some folks who started a facebook campaign got enough people to vote online for the 2015 public radio end-of-the-year top 2000, they got "Gotta catch 'em all" in and public radio was forced to play that. So yes, there are still reasons to listen to public radio.

sorry I know this isn't a landline but it's funnyquote:During the network news presented from Wellington, if an inject was required from Auckland, Auckland would switch from transmitting Wellington pictures to transmitting, briefly a black screen with a small white "A" in the corner. Then each transmitter down the country would have to switch over so that the "A" would eventually appear in Wellington and beyond. Once all centres could see the "A" caption, the Auckland inject would be played. At the end of the item, the process would be reversed with a "W" for Wellington being switched sequentially, and then finally the Wellington presenter would appear again in all centres. The viewer would see a black non-synchronous switch which would take a second or so. Eagle-eyed viewers could see the identification letters change on the corner of the screen. Those with poor vertical hold would have to wait a little longer for the picture to stabilise. Occasionally, a transmitter would be switched out of sequence and the viewers would be treated to the sight of 100 kW of video feedback. https://en.m.wikipedia.org/wiki/TV_One_(New_Zealand) thehustler fucked around with this message at 21:28 on Jan 10, 2016 |

one of the things we'll have at ranch 290, which will have several outbuildings spaced out on a 20-100 acre plot, will be a telephone network it will probably be asterisk-based but will have a fallback network of field telephones with the accompanying switchboard
