Ota here would be just 2 channels. Tubitv seems to work ok. Internet speed 640 kbps. It sometimes buffers.

But it's likely they would be HD, crystal clear and no buffering!

That will barely get you "SD 480" quality if you are lucky.

To understand what you are up against, you have to look at what it takes to stream it and how your bandwidth/data speed affects the quality of what you get.

SD 480 is sort of the "base line" of video, fairly close to analog NTSC video if you will, it is like taking a digital picture on a camera with 1 megapixel or less resolution.. In reality matches to your PC screen resolution being set to 640x480.

To squeeze the stream through a connection of only 640 kbps that 640x480 resolution will be reduced to something a lot closer to 320x240 pixels all the way down to 160x180 pixels depending on how much storage space and bandwidth the streamer wants to allow.. Lower resolution = smaller video file to store and host.

320x240 viewed on a 17" laptop screen in "native size" is going to look a lot like a postage stamp on a envelope and expanding that to full screen will be extremely blocky/unwatchable.. Put it on a 50" screen and it is going to look horrible.

Then you have to consider there is something called "video Codecs" these are in a nutshell different ways and types of "compression" of encoding the video into digital form.. Some Codecs are horribly high data loss and result is a highly compressed video. The more compression, the more loss of data results in even worse video quality but the higher compression makes for a smaller video file to store.

This is one of those things that you cannot "have your cake and eat it too"..

Youtube is a good example of how bad some streaming video can look like.. When you upload a video to YouTube, they "re encode" the video to reduce the file size, reduce the amount of bandwidth your file will use when someone watches it. Generally really kills the quality.

A former co worker would often complain that the 4K videos he was making looked great on his PC, but the ones he uploaded to YouTube looked terrible when he streamed it back. He was using YouTube channels to distribute the videos of a band he was in to other bandmembers.. I told him that he needs to stop loading to YouTube and find a online file host to upload the unadulterated files that he can setup file sharing because of the fact that YouTube re encodes the video to a much lower quality.

Anyway, found a website that you might find helpful to understand streaming video a bit better..

You can't have the RV antenna up?

Hate to say it, but I guess your idea of quality, is not the same as mine..

Here is a snapshot of a 320x240 video using H264 Codec..

[image]

Looks pretty darn ugly..

Snapshot of 1280x720 video using AVC1 Codec

[image]

Much sharper, less blocks and can be scaled up much larger (in fact that video has been shown on a 7ft diagonal projector screen).

I don't have any 1080 examples on this PC..

But hey, if you are happy with the first pix quality, have at it, not my kind of gig, I do like to see some detail without the blocks..

Streaming free stuff, is pretty much not for me as all of the free stuff I have found looks like the first pix and I am not about to pay for 10 different streaming services to get the quality of the second photo.

I get razor sharp 1080 HD video on my Dish.. But I do understand that that is not an option for you.

Gdetrailer,

I don't have an example to show you--but I'd say that what I'm seeing is better than the best of the two pictures you displayed, at least on netflix. I did turn the "feed" down to their lowest resolution, to save on bandwidth and I did that before I had the constraints of a cell phone connection.

You tube is a little more variable--but I think that has to do with the quality of the upload from the person donating their materials. Sometimes it is similar to the better of the two pictures, and sometimes it is better.

I do appreciate your expertise.

Seasons Greetings to you all!
