Is the Tube -music video channel at 13.3 having audio problems? I hope this is temporary. Does anyone from the broadcaster have any details? I would love a music channel since MTV forgot about us listeners. Thanks, robby c

The Tube is still in the trial stages here. We got it on air last Friday trying to beat our deadline, but we still have some tweaking to do on it yet. What kind of audio problems did you notice on it? I have no way to monitor it away from the studio, so any input would be great.

Although I have watched TheTube in relatively short sessions, the stereo audio (2/0) has been consistent and good. The video is more difficult to judge, in that the source programming is often dated and originated at far below today's standards. However, degrading video artifacts do show up in the best quality video originations, whereas the WLOS-HD VQ is among the best.

We, as you probably know Jerry, are stuck with a fixed bandwidth. Somewhere in the neighborhood of 19Megs for a channel. The HD sub channel uses the most, obviously, and the SD sub channels use less. But what is happening is we now have to divide the 19Megs up between 3 channels vs only 2 before. So in order to post 13-3, we had to steal some bandwidth from -1 and -2 sub channels. We are still tinkering with the settings to find the best middle ground, but with 3 video intensive sub channels it makes it difficult.

On that note, we are due to receive a software upgrade for our encoders that will help with this some. Its a stat mux application that will constantly redistribute bandwidth where it's needed most at any given instant. I have seen this work at another station I was at prior to coming here, and it does a fair job of it... but it doesn't work miracles.

Thanks for the response. I was concerned b/c some stations were pre-empting.

My sound level is low just on 13.3. NO TROUBLE WITH WLOS OR WB. I have an LG-3510 STB and CM7777 from VHF/UHF mounted on roof here on the west side of Spartanburg near I-26. Some video's have zero sound and some are half of WLOS. The picture quality seems to be as good as 13.1 and 13.2. I have the same problem in the den with ACCURIAN 6000. I am getting 80% strength with SNR 26 on 13.1,13.2 and 13.3. The strength is usually 88%. thanks ROBBY C

Boy... how... de. Bill, does a fixed bandwidth mean "My plate is full"? I'm sure Jerry knows the answer, along will Chalk and Bell. My question... does 13.3 take away from the quality of .1 & .2 and if it does why broadcast it? I have a feeling it may have something to do with $$$$.
Thanks for your input.

bstratton1-- Please don't take more BW away from 13.1! I can live with 13.3 as is, in that the videos were analog origination to begin with and not always with quality equipment. (I aired some 3 hours a day of these videos, 6 days a week, at a station startup in the early 80s...so I know what to expect.)

To answer other questions that have come up, we can expect more and more sub-channels to take away from the HD presentations ... in the interest of adding to the revenue stream. A major article in the WSJ this week detailed recent revenue losses for the broadcast stations, and pointed out most are looking to secondary DT channels to help recover. Fortunately, encoder improvements that allocate bandwidth on a demand basis--and perhaps better compression--will eventually solve some of the problem.

[quote=jerry birdwell]bstratton1-- Please don't take more BW away from 13.1!

If I am watching 13.1, and the encoder decides that 13.3 needs more bandwidth and does it's job, will the 13.1 signal decrease?

At least WLOS didn't give us yet another weather subchannel. With the weather radar on 21.2, NBC Weather Plus on 4.2 and WSPA's Weather Plus clone on 7.2, we're well covered in that area.

But I thought I read somewhere that ABC is working on a 24/7 news channel for its affiliates. Or was it CBS? If we're going to have subchannels anyway, I'd love to see one of those.

With analog TV, the two things I really missed by not having cable at home, after watching it in motels while traveling, were (a) the Weather Channel and (b) CNN Headline News, at least when they're in news-show mode and not talk-show mode (Nancy Grace, ewww! ). With digital TV, I now have a substitute for (a) but not yet for (b).

As of right now we are protecting 13.1 as much as we can. I'm an HD viewer too, and would not like to see the HD quality go down in order to put another sub channel up. But there is an old saying of "trying to put 10lbs of junk in a 5lb bag". Thats what broadcasters are up against right now, until better technology allows us to expand our resources.

With the Stat Mux application I mentioned, it will not lower or increase your signal strength at all. It simply allocates bandwidth where it is needed most. I know on the Harris Encoder at another station, we could also put priorty ratings on each sub channel. The human eye should never see it work since its job is to make the video/audio less flawed by giving the sub channel a touch more bandwidth if it can. As I stated before, it works pretty well.. but don't expect any miracles.

The low level audio I will look into. I know we have an audio "issue" with The Tube now in that all the audio is coming in very low. I don't understand why some videos are worse than others... unless the difference is in a newer video vs an older one and there is something going on with the dolby 5.1 or stereo. I'll check into it though. Thanks for the input!
post #3192 of 9751
thanks bstratton1 for the info. i was just trying to give positive feedback on a new offering. I agree 100% that WLOS HD should get top priority. I am thrilled by the possibilities of multicasting. Thanks also to Jerry for all the work you do with this website. robby c from spartanburg

I have checked out 13.3 The Tube a little and so far I like the channel. My issue with the audio is that the voices and other sounds from the center channel are coming from the back surround setup in my 6.1 setup. The front LR channels seem to be working fine, however. Audio level does not seem low from my Dish 622.

Jerry & Enoree, can you guys help me out with something? I've got HD through DISH (which I assume is E*), but only have one DVR receiver (951?) in the living room.

I've got the go ahead to get an LCD in the back room, so I'll need another reciever. I'd like to get one that I can get ESPN-2 in HD. Does that require the MPEG4 reciever from DISH? Are they selling those yet? Are they offering upgrade deals on old receivers?

I can't help you with the Dish plans for MPG4, but I am sure others are on top of this.

When is Charter going to get WLOS HD. Are they still fighting with Sinclair?
post #3197 of 9751
I think that would be correct Jeff. However, I am not in a position to be in the "know" of it.
post #3198 of 9751
Dish is doing MPEG4, although for some channels it is just a MPEG4 flag. They have an upgrade path on their website for current and new customers. The HD packs are Bronze, Silver,Gold and Platinum. or basically the Top60, Top120, and Top180 with HD. They currently offer 25HD's with Bronze and Silver, 26 with Gold and 29 with Platinum. They will add the local HD's this fall and another group of national HD's plus HD regional sports nets. It will be a long time before Charter can match this.
post #3199 of 9751
This afternoon I flipped past channel 40 during a station break and saw "WMYA-TV/DT Anderson Greenville Spartanburg" in small print at the bottom of an ad. Sure enough, Sinclair's Web site http://www.sbgi.net/ now lists the station as "WMYA (formerly WBSC)." No change in PSIP or the broadcast "WB40" logos yet.

It looks like Sinclair is changing those station names that include "WB". Other examples are KVWB --> KVMY in Las Vegas and KMWB --> WUCW in Minneapolis.

enoree -- Nowhere did I find on the Dish website a clear statement that the DVR offered by dish is MPG4 and that it will be used for LIL. Additional info that I would like is the Satellite positions for LIL. My current DirecTV is through a fairly narrow "window" between trees and a mountain that rises just to the north of the opening. It was selected to serve a Directv port built into the side of the house, but I am not sure it will accomodate Dish. Got any info? Will they release a DVR with MPG4 prior to LIL? Thanks.

Thanks
post #3201 of 9751
The new HD DVR IS MPEG4, it's the 622. http://www.satelliteguys.us/showthread.php?t=65712 will let you know the orbital locations and new dishes for them. The VOOM HD is also on the 61.5 bird too.
post #3202 of 9751
Haven't looked at 13 digital in a couple of days, but tonight their signal is in the upper 80's and steady. Hope it's not the weather. Has 13 improved for anyone else?

Three hours later:::

Never mind. Must have been a cloud. Signal is now below 70 with dropouts.

Jerry I need some advice. I live in Easley, SC kind of in a valley with a lot of trees. I just bought a Radio Shack XR190 antenna. Installed on a gable mount @10 ft. above rooftop. I Have a Hughes H10 HD reciever. I pointed to WYFF channel 4 and got a good signal (75%) on 4.1 & 4.2. Also got a good signal on 7.1, 7.2, 7.3. I got a weak signal on Fox 21 (anolog) but no 21.1 and could not pickup 13 at all so I bought a Channel Master rotor and installed. This let me get a 90% signal on both 4 & 7 with a little improvement on 21. My question is will an amplifier help my signal for 21 & 21.1 & finding 13 or will I just be wasting my money. Also is 21's signal weak? They are the only station that gave me a waiver to recieve FOX NY HD with D*.

If you were granted a waiver by WHNS it was based on your home address showing as "underserved"* by Fox and your ability to receive less than a grade B signal (SHVERA rules). It is not a perfect measurement, but comes close. However, I still think you should check in with Antenna Web for an evaluation of your ability to receive local stations.
If weak signals are your problem and trees plus your terrain would cause that, a good RF amp would probably help. I certainly suggest a CM which is designed to handle a wide range of signal strengths without overload.
Still...you must recognize that the RF Amp also is subject to overload by many VHF and UHF transmissions, including local public service and FM stations. All DT stations but Channel DT-9 (PBS) in Greenville, are currently UHF but that will change in a couple of years.
Finally, it seems that the local area has been better served by a UHF only antenna such as the 4 or 8 bay CM, and that could be a potential solution for you.
*--Signal estimates are just that...predicted signal strength by a FCC approved technology that is provided by an independent source (Proximity TV). Fortunately DT signals are being received fairly reliably by many using a reflection...so search a full 360 degrees for missing signals.
Hopefully you will get other advice from someone in your immediate area.

Good Luck.

My tuner is able to get a hint of a signal on WYCW DT for the first time. I hope this is not the full power strength.
post #3206 of 9751

WYCW-DT is its normal 100% for me. However, if your desire is to watch the station, try WSPA's 7-3.
post #3207 of 9751
I have always been able to get analog WYCW 62 better by pointing the antenna north toward Virginia. The DTV experts say that digital is more directional and this type of thing will not happen with digital reception. After having no luck getting WYCW DT from the proper direction (S-SE), I tried aiming my antenna north at Virginia and got a good DT signal at around 55-60%. This backwards phenomenon only happens with WYCW and it may sound insane, but it works. I now get 62 programming and the 7 Weather channel on 62-2 with the antenna aimed at VA.

Depending on the antenna, you may have a lobe on the back side...but normally it will have less gain than the front. But more likely, you are receiving a reflected signal from some object in the direction of the greatest reception. Could be a water tank, hillside, building...many things. I receive good reflected signals from some of the local stations but the reflection is not as stable as the primary signal. Some of the DT RF experts may have better information.
post #3209 of 9751
I live near Anderson and get frequent dropouts on 13, and occasionally 7. 21 does not come in at all. I am using a DirecTivo tuner (not very good) and CM 8 bay bowtie with preamp. Will turning on the VHF trap help my signal? I hate to pull the mast back down to switch it if not (that thing is heavy.) My antenna is currently just above roof peak level.
post #3210 of 9751
Thread Starter 
In my opinion, the use of the VHF portion of the amplifier, or not, should make little difference in that you have a UHF only antenna with very little low frequency pickup. I assume the preamp is a CM. What model? Are you feeding the VHF input a signal? Do you have any type of obstruction between you and the two problem stations. As I recall, most of the Anderson area has a good clear line of site to Pisgah. I am not sure about your line of sight to Hogback. What does Antenna web reveal about your antenna location?
