This one's got me scratching my head. I scanned in a channel last night, WGHP channel 8 from the triad area of NC. 8.1 is HD, and 8.2 (Antenna TV) is in SD. I was checking the info from the station, and I noticed that 8.2 was broadcast in 480i, 16x9. All of the sub channels on other locals are 480i 4x3. I have all SD channels on my 722 set at full zoom, but 8.2 doesn't full zoom without also changing ALL HD channels to full zoom. The problem with the 16x9 on 8.2 is, all of the programming is 4x3, on a 16x9 format.

The pic shows 4x3, in a 16x9 format, if that makes sense. Any of yall have channels like that?

None here.

By transmitting a 4X3 picture with sidepanels the effective resolution is decreased because fewer pixels are filled with picture elements. The MPEG2 coefficients for the sidepanels are all zeros. That makes the picture quality of the subchannel lower, but allows more bits to be allocated to the main channel, causing it's picture quality to increase. CATV systems can use 544 horizontal pixels with 4X3 video to achieve the same goal, but 544 is not an over the air standard. Yet a few stations have used 544 and it seems to work.

I can answer this since I work there.

Yes, it is 720x480i but anamorphic with the 16:9 bit set to be sure the the display formats the picture correctly. The network programming is 4:3 with anamorphic format added locally, but when we start to add local commercials, they will be in 16:9. The signal path we are using is an all digital anamorphic path so it does not have the analog artifacts of PQ degradation that you see when this is done with an analog signal. Any analog in the path would show PQ degradation but not with SDI.. FOX network also used 4:3 anamorphic in network distribution in their pre HD days of "FOX Digital Widescreen" from 2001 to 2004 as well with an all digital path. We used this same set up for over a year on our main channel with no viewer complaints while we converted our master control to HD. We have had no viewer complaints on 8.2 either.

yes...partially
A station I can pick up (KEYC) has CBS on main and Fox on subchannel (its the only channel in the market). During Primetime (and during sports) KEYC-DT2 is 16:9 otherwise its black bar hell. Station is in 480i

Thanks for the reply Ice, and thanks foxeng and Tower Guy for explaining the tech of it. :)

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....

Lately my eight year old Dell laptop has been shutting off even when I have a full battery. I have had to keep it plugged up all the time to keep this from happening. Any idea what is causing this? I replaced the battery about three years ago.

A recalibration might be needed. Even if it shows full, the individual cells may have become unbalaced. And the BMS chip in the battery reports false information to the pc.
Try this. Start it up in the bios/uefi and leave it there until the battery dies and it shuts off.
It might just keep running longer than in Windows. Or run for a short while and shut off.
If it's the first case. Probably just needs a balancing. If the latter, the pack might just be dead.
Not throwing stones but perhaps just a cheaply constructed battery with substandard cells. Could be.

Patience. Keep restarting it in bios/uefi until it won't fire up anymore.
Then plug the charger in and let it complete a full charge. And see what happens. If it's better.
Do the same thing one more time. Run it until it dies dead-dead. Then just let it charge, pc shut off.
When charged, it might be better. It might not be.

There are bench jigs that read the actual BMS and override it to let a tech manually monitor and charge the separate packs. They can also reset any "time bombs" in it that cause an otherwise good pack to show bad.
Maybe Santa will be good to me some year.

You might just need a new battery. Maybe the PC power management chip is going. A Dell common thing.
Leaving a laptop plugged in with a full battery is known to reduce the life. Asus for one recommends that you don't leave the charger plugged in all of the time even when shut down. And setting Windows to charge the battery to 85% instead of 100% increases life.
That's all I got.

That was quite enough....I definitely learned something from your post. Thanks

I set up a music server for my brother a few years ago. It's basically a small headless computer but it needs to have a DHCP IP address reserved for it in the router settings. This was easy to do in his DSL router. He's switching to Starlink now and I was wondering if these setting are easily accessible in the Starlink router. I'm pretty sure he will be getting the latest V5 router.

If you can't get into the router to reserve an IP address just don't use DHCP on the device that needs connected and assign it to a specific IP address in the network settings.

They are not. Your best bet is to set up a third-party router, attached to the Starlink for your server, that you can get into, like a Linksys, etc

The Starlink V5 Install Kit I just got comes with the Mini Router. It is pretty limited in what it can do. For example, it can provide only one IP subnet at a time, no Guest Network, but it does support the pass-thru to a third-party Router. You can also split the Wi-Fi into separate 5 GHz & 2.4 GHz SSIDs to help some IoT devices that don't support 5 GHz bands to work.

The larger Starlink Router that still comes with the V4 Kit does support a Guest Network with separate IPv4 Subnet, but it's $120 from Starlink. And it still won't do DHCP Reservations.

If you can restrict the DHCP address space to assign addresses to one end of the subnet (i.e. x.x.x.50+), you can manually assign the IP address on pretty much any operating system. This is a default behavior on several popular routers. As the Router Mini only supports 235 devices, I expect that's already done.

Another option is to use a router that supports PoE to power the antenna. This article discusses that option (under PoE Power heading):

Now that I've had the v5 kit with the Mini Router, it's not as bad as I first thought. Yes, no DHCP reservations, but you can set up multiple SSIDs that have separate IPv4 subnets, and like the big brother, you can select from 192.168.x.0/24 or 10.x.0.0/16 (where "x" is 1-4).

You can also split a subnet and have different SSIDs for the 5 GHz and 2.4 GHz channels to handle some IoT devices. I haven't discovered what subnet the 2nd NIC on the router assigns, I'm guessing it's the first subnet.

Terrible tragedy. You would think that they would have safe guards in place that would prevent something like this from happening. I guess if you are going to ride in a passenger train it might be best to get a car near the rear.

They will have to look at the switching sections to determine WHY 2 trains were on the same track ... at the same time.

Thought this article might be of interest to some of you who might travel via train.
