Re: [Content] So does Comcast ever add channels?

On another forum, someone told me the reason we see no adds is essentially, Comcast is out of space which is the reason they are pushing ON DEMAND so hard.

Is this true?

They moved all of limited basic to digital. Surely some space was freed up for 25 ish QAM slots.

Around here extended basic was analog, and that was moved to digital. I suspect close to 100 analog (i.e., 6MHz wide) channels were freed up.

Figure 3 HD channels or 5 SD channels per 6MHz analog channel?

I'm thinking Comcast wants to get a few more price increases through before they add channels and then charge for the added channels.

hmm most systems only topped out analog at channel 78 so probably 78 or less analogs were removed. it is 3 HD or 10 to 15 SD channels per QAM.

I think many of those freed-up QAM slots are being used to provide more downstream HSI carriers (many systems are expanding to 16 DS channels now) with other reserved for upcoming DOCSIS 3.1 use.

Thanks for the correction. I wasn't sure about the number of SD per channel.

Well I posed the question of why none of the sports packages are shown in HD and that was the answer I received on the main Comcast forum.

But most systems already had 8 DS carriers. So you free up 25 channels and you add 8 more DS. You still have 17 open slots.

This is assuming that the first analog transition of Expanded Basic a few years back had its entire bandwidth 100% utilized prior to limited basic going full digital.

How much are they sitting on for D3.1?

Yes, they're out of "TV space," and using/withholding other spectrum space for HSI use now.

They may also be looking to provide up to 24 DS HSI carriers, given that they are providing/using 24xN gateways now.

DOCSIS 3.1 Targets 10-Gig Downstream
By Jeff Baumgartner, Light Reading Cable - October 18, 2012
»www.lightreading.com/cable-video···d/699136
quote:
... To hit its capacity targets, the cable industry wants to increase its spectral efficiency by about 50 percent. As expected, the new specs will do away with 6MHz- and 8MHz-wide channel spacing and instead use smaller (20KHz-to-50KHz-wide) orthogonal frequency division multiplexing (OFDM) subcarriers; these can be bonded inside a block spectrum that could end up being about 200MHz wide.

If it ends up being 200 MHz, then that knocks out 34 RF channels right there. More if they increase the return. Though if they have to visit every node/amp to change diplex filters, might as well drop in 1 GHz upgrade packs while they are there.

They just really need to buy TWC to absorb their space saving SDV and unified channel lineup technology. TWC knows what they are doing in video, as Comcast does in Internet, Phone and Metro-E. Could be a good combination if they actually do share technology resources.

Most likely they will start with a smaller block size than 200 MHz, possibly just 100 MHz, and increase it once they start removing DOCSIS 3.0 QAMs (and some more Video ones).

Docsis 3.1 block sizes start at 96 MHz (16 channels) and some of that can be used to service earlier Docsis version modems.

Well I'll be.... Time to upgrade past 750 MHz!

That's another thing I've noticed. I know many Comcast systems that are only 750. Now they are pushing its limits to bleeding edge... 770 MHz or so, but from my experience more Time Warner systems are 860.

I have service electric and they are 860 Mhz. A few months ago they moved the limited basic to digital clear qam. Here is a band scan with an SDR scanner. The tall spikes are analog colorbars on channels 2,16,54,70,135. The spike at the far right around 932 MHz is a harmonic image of the colorbars on channel 16. There's another spike at 75 MHz for set top control as well.

According to the official Comcast forum they will be adding sd and hd. In the sec states it will be on digital starter everywhere else digital preferred.

Just found out here in Chicago, SEC SD will be on 421, and HD on 336. We are also getting UToo HD (broadcast WMEU-CD 48.1) on channel 230. All this on 8/14.

To quickly locate the SEC Network (once it is available) –

Using the silver Comcast remote control and traditional blue on-screen guide, press the Menu button twice, then select Find Shows, then select Sports, then select All Sports – you should be able to scroll through that list up and down to locate the SEC Network in SD or HD.

X1 customers with our black on-screen guide. Using the black Comcast remote control, enter in SEC (numbers 7-3-2) and the SEC Network should appear as an option near the top of the list. Select and press OK.

Is SEC Network part of Sports and Entertainment Package? Or did they demand carriage on a lower tier (like NFL network did). For comparison without the sports pack, on DirecTV SEC Network HD comes in fine. Not sure if its a promotional thing, or if everyone's bill will go up to compensate for the carriage rate of $1.30 per-subscriber per-month in SEC markets or $0.25 in non-SEC markets for a channel whether you subscribe to sports or not.

This is more of a carrier agnostic question I guess.

2 HD channels??

Here in Chicago, both of the SEC channels (SD and HD) are sharing the frequency with the Xfinity 3D channel. The ESPN 3D channel also used to share that frequency, so they are just re-using it.
