Fuck Time Warner Cable. You people with Comcast don't know how good you've got it. I count the seconds until I can get FIOS - and I hate Verizon. Time Warner is
that bad - they have the power to make Comcast and Verizon look
good. I spend
days trying to call them and only got a busy signal every time - I actually got a
busy signal from these idiots. First busy signal I've gotten in literally
years. At least Verizon will make the effort to pretend that they care. Time Warner straight up
doesn't want to talk to you and they make no bones about it.

Well, you connect a
decent antenna, rooftop is of course best, to your HDTV (or your external tuner box if your HDTV or computer monitor lacks a built in digital tuner). If you live in an apartment building check if there's an antenna already on your roof - if there is, then there you go. Then you watch TV. This won't get you cable channels, but not everyone wants or needs the cable channels, and for some people the cost-benefit ratio of cable just doesn't pan out like it used to. (Why pay more money for the benefit of watching more channels with more commercials? Shouldn't
the commercials pay for that?)
Since this ATSC system allows for multiplexing of channels (each channel carrying several streams that appear as virtual "channels" to the end user), and since with digital broadcasts you can squeeze in more channels closer to each other, the number of local "channels" you can have in any given market has just exponentially increased. And since you can have multiple "channels" to a channel, and a
vast array of valid resolutions in the ATSC system (PDF Link), independent broadcasters who would ordinarily be competing to score a slice of RF spectrum for an analog station can team up and literally share that spectrum - one channel can hold probably 4 to 6 high-quality streams (virtual channels) of DVD-grade video with stereo or 5.1 audio. Throw a 1080i/DD 5.1 stream onto a channel and you still have room for a couple of 480p/DD 2.0 channels at reasonable quality. If you want to take it down to VCD's resolution of 352x240, which is the lowest allowed under ATSC, then you could cram probably 10 to 15 of those streams into a channel at reasonable bitrates. Audio-only streams are permitted as well - these use truly negligible portions of your bitrate. ATSC supports the time-honored audio standards of MP2 and Dolby Digital (AC-3). The point being, you can split the risks and share the rewards of operating an independent TV station more effectively than you could under analog NTSC and one "channel" per channel. I can't wait for the ATSC "co-op" stations to start popping up. Local TV is about to get real interesting.
