The Channel Plus 6110 displays Caller ID info on your TV when land line calls come in... but it has a few tricks up its sleeve which lets us send custom text from a computer over serial. Let's figure out how it works.

That home cable thing is really nice. I also had a nice chuckle at "there's a problem if the pizza place is calling you"!

@probnotstech 10 месяцев назад

It's great that they decided to include that serial port, so that it's not just locked down to Caller ID functions. Doing an old school "UP NEXT..." along the bottom during the credits would be pretty sweet as well. Also your HomeCable idea is so much more elegant and centralized vs my "we need ALL the USB flash drives!" approach.

@clabretro 10 месяцев назад

Totally agree about that serial port, such a nice addition. It's what made me pick the thing up in the first place. Not sure what they had in mind with it, or if it was used in commercial applications or whatever, but definitely makes it more interesting now days.

@theserialport 11 месяцев назад

Great work bringing it to life. It reminds me of seeing the caller-id text on screen function that I saw working on a Directv receiver 20+ years ago

@clabretro 11 месяцев назад

Ha interesting. We had a Directv receiver of the same era, and now that I do some research I think it was this one: blog.solidsignal.com/wp-content/uploads/2021/10/s-l1600.jpg Which makes my DSS joke even funnier.

@insainllama 10 месяцев назад

My family had this feature enabled on our DIRECTV receivers up until 2018 when we ditched the landline. Was supported I believe up until this year when they released their new Gemini boxes.

Typing ASCII control characters is easy. If the control code for display reset is listed as "X" you press Control+X. Normally this would be written with a caret as "^X". This should work easily for most control codes. The big exception for you is when your terminal software "hogs" a control key, in your case minicom reserves ^A (in its manual they call it C-A). To send a ^A using minicom you need to type it twice. The other common exception is the XON/XOFF flow control characters ^Q and ^S but this probably isn't an issue in your situation.

"How to watch DSS in the bedroom" --DSS was the name for what turned into DirecTV. In the late 90s when it first started, DSS was a satellite platform through which multiple companies sold video services. Eventually DirecTV bought the other company and it turned into a closed platform. ANYWAY, back when DSS first hit the scene you could only have one set top box in your house, or two if you got a more expensive system but most people didn't. It was super common to redistribute the RF output from the only satellite box in the house to all the other TVs. These guys probably sold some gear to make that setup "easier"

@clabretro 10 месяцев назад

the funny thing is, I actually had one of those DSS satellite boxes as a kid, didn't realize it until you and some others commented about it!

This thing probably uses the MAX7456 chip. It is commonly used in drones for overlays. There are a lot of DIY boards for that chip, which would connect to the pi via a SPI port. It is also possible to use an arm M1+ microcontroller instead of the MAX7456 chip to do the overlay.

I LOVE the HomeCable concept. I have a small collection of portable TV's (4"-8") from the 80's I'd like to get set up as kinda 'art peices' around the house, you know, playing period correct TV shows on rotation. even go to the lengths of finding some of the actually good ads from the era, and the 'TONIGHT on channel 9 NEEEEWS' 30s clips. I can fix the TV's, n have messed about a bit with Pi's, but I in no way have the skills to set up more than a giant VLC playlist on random. this sounds like a heaps better option. very cool idea. I'd try it out for sure.

@clabretro 10 месяцев назад

collection sounds awesome. I'll keep you posted as I make updates!

@dominicus9891 10 месяцев назад

7:04 The musical notes could be because the chip inside might be shared with TV on screen displays. Like if you wanted to change the sound settings, it'd have a musical note as the icon. Also, the symbols next to the musical notes could be a "change input" symbol. I know a lot of sets which use a symbol like that to mean "input".

@clabretro 10 месяцев назад

Ascii control characters all have their 7th bit set to 0. But you can type them by using the character with the same value in bits 0-6 but with the 7th bit set high. For example the CAN control character is b00011000 or 0x18. The corresponding character with the same value for bits 0 to 6 and bit 7 high is b01011000 0x58. Thats the upper case X character. If you press the "literal" key first which is usually control-v then press control-shift-x it will type a CAN control character. This depends on the mode of the ptty and wont work in all situations. The man ascii manpage is a great resource for this and is laid out in a table where these features grouped in blocks relationship makes sense. In vim/neovim :set list will show you control characters visually.

(15:39) Your idea of an older Raspberry Pi to play video as though it were an old pay TV channel reminded me of some side projects I wanted to do but couldn't do them or don't yet have the time to do so. In particular, with my Pi, I would've manually loaded video files into VLC when I wanted. Another idea I had was similar to what RU-vid user '12voltvids' did where he had external TV tuners (in his case, ATSC tuners, but I would use DVB tuners instead) connected to RF modulators which then connected to the existing cable TV wiring in his home which had already been disconnected from the outside. I had planned to do so especially with the legacy SCV cable network having been discontinued in 2019 and some companies here selling MoCA adaptors to allow them to be reused, but I ended up moving to an older home which had already had its legacy cable wiring and connection points removed. I wasn't going to spend lots of money for a side project, so I cancelled it. (17:47) Following my childhood memories of a children's hospital in 2005 which had an in-house channel on their ward TVs (alongside the usual over-the-air Mediacorp TV channels) that was just an RF modulator connected to a 100 disc Philips VCD changer (VCD was still popular in Singapore at the time), I imagined adding additional indicators to the OSD to make it seem as though the videos were being played off of a VCD player/changer or VHS recorder/player. (Edit: the VCD changer mostly had Bob the Builder, Thomas, and Barney VCDs loaded into it, and I can't remember if it played any other VCDs. I then remembered that some of the TVs in the waiting areas were also tuned into that 'channel' too.)

@clabretro 10 месяцев назад

Super interesting about that VCD changer. I have a LaserDisc player I've been thinking about getting hooked up to these things so I can watch the LaserDiscs throughout the house. 12voltvids setup was actually one of my inspirations for this project!

@kbhasi 10 месяцев назад

@@clabretro I was not able to find any info online about the VCD changer, but I knew it was made by Philips because there was an OSD shown while changing discs, which when it had trouble trying to read one disc, showed 'PHILIPS' in the middle of the screen as a splash screen of sorts. The OSD was based on a character generator of some kind (which VHS recorders/players and VCD players used) and was displayed on top of a plain blue background. (Edit: the text was in white with a black outline) When it showed up in between discs, it showed a graphic on the left half of the screen (4:3 PAL) of a vertical stack of discs with indicators for (as far as I can remember) 1, 25, 50, 75, and 100, and one of the discs in the stack graphic would blink to indicate that it was picked as the next one to play. On the right half, the slot number of the disc was shown, as well as something to indicate that the disc was being brought over to the CD drive or that it was loading. Once the disc was loaded and began playing, the OSD showed a regular 'PLAY' indicator like what a consumer model Philips VCD player/changer would've probably shown (I'm not sure as we had a Pioneer VCD player at home instead, and later Toshiba and Sharp DVD players). The player was set to repeat all discs in order. Yep, the discs were stacked rather than being placed on a large carousel. I couldn't find any information online about it as it was never sold on the consumer market, only to businesses. I know the hospital, which was KK Children's Hospital (as it was in 2005), had Philips TVs and wireless headphones, so it made sense that they would've also purchased the VCD changers through the connections SingHealth (who owns KKH children's and women's) would've had with Philips Healthcare.
