- Remember back in the days when if you didn't pay for a channel, this is all you got? Keep in mind that youtube really compressed this and it looks a lot better than you see here

The primary purpose of this feed was to send weather data to smaller cable companies, who were still using the older, analog-only WeatherStar 4000 and XL systems instead of the newer, digital IntelliStar systems.
i have been looking for this scrambling effect. kind of surprised there aren't more youtube videos that demonstrate it. thanks, uploader /thumbsup
and it looks horrible on here - its extremely overcompressed after I uploaded it. Wish it could look like when I capured it
@Zcooger Second Channel I have a bunch that I captured directly on the computer more or less uncompressed. They look terrible on here. I just added another one and the same issue. On my end, every frame looks like this i.imgur.com/lpBVaDS_d.webp?maxwidth=760&fidelity=grand
This is what would of happenned if FiOS was analog. They took away the Weather Channel from us years ago.
Now i understand how this scrambling system works. You can see that the horizontal and vertical sync pulses have been replaced by digital codes, and the smart card decrypts these codes to recover the sync pulses.
Most of that digital code is uncompressed PCM discreet stereo audio. I think it was close to, or even the same as CD quality. Also included was closed captioning, and program info such as time remaining on the show, name and channel of current program, and name of next program. Also, scrambling info was included, showing if it needed a subscription or not, and receiver IDs that were authorized to view it. (From past experience, it was only a few seconds from subscribing online to a channel, for the datastream to come over the satellite and authorize the channel)
@@mattcintosh2 But those codes are in the same positions as the horizontal and vertical sync pulses, and if the proper sync signals are not present, the TV will not be able to put the video lines into their proper positions on the screen, resulting in this kind of jumbled mess.
Is there a way to get the VC2 to scramble regular composite video?
Unfortunately, no. Seems to be a one way process. I have a external unit (gi-2100e), but if you feed unscrambled video through it, it just comes through the same way. A lot of the effect is due to the digital audio data on the sides, and you would need something to encode and insert that. As for how many encoders there were, it had to be low. Maybe a couple hundred . The highest amount of VCII channels at any time between 1985 and 2008 was probably in the low hundreds, and defunct channels probably either sold the equipment to other channels, or just leased space at an uplink facility. Wonder what ever happened to all the encoders (most likely a couple rack mount devices). If you paid for a channel, there was one (or maybe 2 or 3) facilities that somehow added data to the stream to unlock your receiver for all the channels you paid for. Anyone know more of how that worked?
And of course, this is now gone.......for a couple of years now too.
James Stanley Barr Actually, just barely a year. It turned off June 26, 2014. The data in the VCII feed actually ran something called Weatherstar for the local forecasts "on the 8's"
Glad my cable system only scrambled the video back in the day. You could buy a descambler for a couple of hundred bucks and get all the channels including pay per view. Are they still scrambling any channels on C band now? I'm guessing they are all digital now.
VideoCipher has been gone for almost 10 years. Subscribable DigiCipher is gone (there might be a few high bandwidth channels that need a commercial receiver, some Mexican channels and possibly Canadian Shaw Direct [Star choice]).
There might be a couple of free analog channels, occasional feeds, CSPAN and a religious channel or two, but everything else is free digital, or encrypted digital that isn't intended to home users.
looks like the D2 MAC system used back in the 90's but without the Eurocrypt encryption, the sound was digital too but came out as static without a decoder
D2-MAC is different but you are right, the data stream and audio was digital.
Look for D2MAC HackRF videos on UA-cam. This TV system is back to live thanks to SDR!
Hahaha this is cracking me up
Hi, Do you still have more VCII+ videos to upload?
Check my other videos. In one of thge comments, i linked some uncompressed versions ( a 3min vid is 1gb)
How did U upload this video?
I had a capture card on my computer in the mid 2000s. I ran a composite cable from the baseband out jack on the receiver to the input on my computer
Sound?
Generally, no. Videocipher II used encrypted stereo digital audio. I forget what subcarrier they put it on, but generally on a Videocipher channel, the 5.8 MHz and 6.2 MHz are silent, or just have a barker audio (The discovery channel is available from your satellite provider for $xx a month...). Even if I had tuned the audio, it would have virtually sounded indistinguishable from static.
Actually... Go to 1:35 see the vertical bar in the middle with all the dots? Thats the digital sound.
The sound is located in the horizontal sync part of the video signal. They replaced the sync pulse that your TV set normally uses to lock into the signal with, with a digital data stream. The binary 1's and 0's are represent by a series of black and white dots. If you look closely at that squiggly bar going down the scramble picture. You will notice that the last 1/3 of it is a shimmering rainbow and the first 2/3 of it contains what appears to be TV snow( It appears a little muddy because of You Tube compression). That TV snow looking stuff is the data stream. The reason why it appears random like TV snow is because it's all encrypted with the DES cypher. The scramble audio is an integral part of the video signal and no part of it is carried in the barker audio channels.
It all depended. I can remember a few times I "watched" concert/sporting events in scrambled, the TV in my basement had the audio cut in and out but the TV in my living room usually had the audio clear the whole time (so I typically used the living room TV)
its the weather chanel
It could be, when I was younger The Weather Channel was one of a few channels that cost an extra 50 cents per month to get.

It was replaced with DigiCipher, but wasn't nearly as successful for consumers. I think at one time there was almost 100 VCII channels, but DCII (DC 1 was used mostly on PrimeStar) seemed to be a lot of movie channels and commercial feeds that couldn't be received with consumer equipment.
