There on the wall in the corner of the room was a mysterious switch.

  • There seems to be a problem serving the request at this time.
  • Jerrold Electronics was an American provider of cable television equipment, including subscriber converter boxes, distribution network equipment amplifiers , multitap outlets , and headend equipment in the United States.

There on the wall in the corner of the room was a mysterious switch. Housed on a standard-sized British electrical fascia was a position rotary switch, marked with letters A through L. If you have cable TV, there is probably a co-axial cable coming into your home.

It is likely to carry a VHF signal, either a series of traditional analogue channels or a set of digital multiplexes. Your digital cable TV set-top box will do a similar thing, giving you the channels you have subscribed to as it decodes the multiplex. At the dawn of television transmission though, none of this would have been possible. Co-axial cable was expensive and not particularly high quality, and transistorised wideband VHF tuners were still a very long way away.

Entire cities will miss the chance to see important events, so they are fitted with a network of twisted pair cables in a tree topology of multiple nodes with repeater boxes on street corners.

There were tubes available that could do VHF and even UHF in the post-war period, but the twisted-pair network only had a bandwidth somewhere in the HF. The solution was to vestigial-sideband modulate video for distribution onto an HF carrier. In the home, instead of a broadcast TV set the subscriber had a Rediffusion-branded TV with a built-in demodulator. At the close of the s the country moved from the line system to a line PAL colour standard, and the Rediffusion systems were upgraded to cope.

So through the s and early s there were some British cities that still had a s cable TV system. The multichannel future was seen as coming from satellite broadcasting instead, and after some ownership changes and mergers the company ceased trading some time at the end of the s. The former Rediffusion regional headquarters was a derelict shell on the main road out of town, and there were technical documents aplenty ripe for the taking. A simple enough circuit with a single transistor could do the job, and as I remember it could even be done with a modified mechanical TV tuner.

There are sites on the web that incorrectly describe the distribution as being at VHF frequencies and suggest the use of a VHF upconverter: these would work, but by an unintended means. Subscriber management was simply a case of disconnecting a house at the junction box, and I remember in particular that my student house was not one of the lucky ones that had been left connected by accident.

Years later, all that remains of the Rediffusion networks are a few relics. Switch boxes in older houses and apartments, a few manhole covers, and very occasionally an intact distribution hub. The idea that there were once miles of multi-way twisted pair cables snaking around the neighbourhoods simply to deliver a pair of low-ish definition black-and-white TV channels seems bizarre in , but for its time it was at the absolute bleeding edge.

If you happen to live in a Rediffusion town, keep an eye out. There have to be some artifacts of the network still remaining. Possibly a future topic for this series, but when we built our new house out in the country in Iowa twenty years ago, we noticed that a lot of our neighbors had parabolic antennas pointing in the same direction.

When we installed a new tv in our bedroom and did a scan for channels, a bunch of interesting UHF channels appeared, including one that was HBO!

A little research on the internet revealed the service known oxymoronically as Wireless Cable….. Channel assignment seemed to change frequently, but at times we could get premium channels like HBO for free. Very cool. This sounds like a very early version of DSL though without the awesomely cool dynamically adaptive multi-carrier scheme.

The receiver was attached to a plastic box via a then standard 2 pin mains plug and the station was selected by a multiway switch on top. It offered a selection of four! Sound quality was excellent but the limited choice of stations doomed the system.

Happy days. When the radio receiver stopped working, I connected the input to the headphone output of a small transistor radio and that way I could still record radio shows on my little cassette recorder. Good times. It was made out of brown bakelite and had a switch to choose from the 4 programs. Note, in the days that the network was active. There were only two national Dutch radio stations, so it was definitely prepared for the future!

Sorry, somewhat OT but geek relevant. Good old British way: they always had to have their own thing. This apparently included a flash cartridge for the SNES, allowing the download of games. At some point along the line one do start to wonder if they could have just switched to coax… Since the coax probably would be better then the twisted pair. Even though a twisted pair of wires and some good differential signaling can technically give 0.

Though, biggest downside with all electrical networks for high bandwidths is the high signal loss for a given distance. While an optical fiber generally has far less loss over the same distance. Maybe it is because of the crappy coax that was out there, and the likely occurrence of crimping a lousy coax connector.

Well no ground loops, and less chance of signal leakage. Cheaper going with plastic instead of glass. Well, the only difference between vacuum and pneumatic tubes is which side you have the lower pressure on. I think they meant the electrical kind of tube. But a vacuum driven pneumatic system is also a thing that works.

Downside here is that the highest differential pressure would only reach 1 atmosphere. Unless one uses both pneumatic pressure and vacuum, then with the same tube we should be able to reach even larger differential pressures.

Unless our tube has horrid tensile strength. I used to holiday in a village in Scotland that due to geography had to have its TV provided in pretty much this way — the village was in the shadow of one of the taller mountains in the area, so while the far side of the loch a few miles away had line of sight on a transmitter mast, the village itself was in the shadow. I believe they ended up with this until the analogue signal was turned off in — no idea what they do now. Hmm, interesting.

There was a company Rediffusion in Switzerland. During the 70s and 80s, their radio and TV stores were a fixture in many small towns. According to Wikipedia they started cable radio in and tested cable TV in In I took a head end and several consumer end units and used them to demonstrate video over power lines at a conference in Paris.

I still have the gear and it was a pretty impressive demonstration. At that time it was still working in Burnley though they had moved to a very small building for the head end and just used a consumer satellite dish for the source, some arrangement with BskyB and Sky. In Burnley they needed to get it to the next town Padiham about four miles away without laying cable so they took a leased line from BT and used it for HF, this was before bandwidth limiters were fitted to the telephone lines.

On the other hand, they did some cool stuff — one connected city trial In Swindon I think had set top boxes which were basically Macintosh motherboards with some exotic modem installed I think 10broad36 — go look it up — it was a fairly cool tech in its day. I remember stumbling across the HackHull site ages ago and being puzzled by how it described I could open the box on the side of my house and rearrange some wires and get free TV. Opening the box just revealed the traps that were used to provide the pay channels, and I was quite bewildered until I realized the site was in England :-P The cable provider injected a garbage signal that I believe was 4.

One could use a TV with manual fine tuning and get a watchable signal but if you paid for the channel they just installed a notch filter that filtered the garbage signal out. As soon as I saw Redifusion mentioned in the email I figured Jenny would be the author. I grew up on a newly built council estate that had redifusion we had 4 tv channels bbc 1 bbc2 ITV and tyne tees tv.

I was part of HackHull back in the 90s when I was also at University. I remember the rediffusion building including one of the times it caught fire. A little research revealed that the channel in question was in the middle of the FM band. A stripped down clock radio provided the means to see the data, and a D2 kit think: KIM-1 but for the allowed me to look at the bits.

In my region its not uncommon for the water to not be sure which way to flow when it rains a lot. If you want to ingratiate yourself with those folk you will need to acquire a whippet and a flat cap.

This is less true in the era digital cable and cheap consumer electronics. While later televisions were "cable ready" with a standard converter built-in, the existence of premium television aka pay per view and the advent of digital cable have continued the need for various forms of these devices for cable television reception.

Enter the time by using the numeric keys on the remote or set-top keypad.

The Motorola DVR can be operated with a variety of remote controls. Some remotes supplied by cable operators one of which is commonly called the "brown" remote are not programmable.

The silver remote is made by Universal Electronics, and uses the same codes and commands as the 'One-For-All' series. You can find information on programming these remotes at hifi-remote. The silver remote has a 6-pin connector next to the batteries and is JP1. As of September , there is now a cable and software that can let you use your computer to program the remote. Software support for the JP1.

You can find the model number on a sticker in the battery compartment. The forums and code lists at hifi-remote. If your "black remote" is JP1. You can check your remotes version by looking near the 6-pin connector inside the battery area. All other steps work as described below. Some units from Eastlake for example are being shipped with a Motorola DR remote which do not have a "setup" button. Follow the verizon link for a basic programming manual.

As of 12 July , it seems no one has worked out how to program the remote to add in the 30 Second skip feature. For remotes using 5 digits, the first digit corresponds to the device being programmed. The other four digits are the traditional device codes. If a four digit code e. If you couldn't find a code for your device, or none of the listed codes work, you can try a Code Search. This will step through every code, sending a key until you find one that works, or it cycles back to the beginning.

If you forget what device code you used, or it was found using Code Search, the remote can tell you what code is programmed for a device key. The device keys are designed to only work with certain codes. One-For-All remotes call this feature Key-Mover. This is the general procedure for remapping. Several common mapping options specific to the Motorola DVR are listed below.

See Checking your Device Code if you do not know the code for your device. A Shifted key is a second code stored on a key. It is accessed by pressing and releasing the "Setup" key, then pressing the desired key.

The "Setup" key acts like the Shift key on a keyboard. The following technique can be used to restore the original function to a key that has been remapped. You are essentially mapping the key onto itself. The following technique can be used to restore the original function to all remapped keys for a device. The following technique can be used to map an unused or unneeded button on the "silver" remote to the second skip command. Current versions of the i-Guide software will skip forward 30 seconds into a recording when this command is sent.

Note: If you have the dark gray remote and a DCX series cable box, use this procedure. You must temporarily reprogram Aux to Cable, set 30 sec skip, then change Aux to your auxiliary device. Since the "silver" remote's mute button often controls the TV's or HT receiver's mute command, this allows you to re-enable the sound if the box has muted itself see "MUTE" bug.

Some companies have the remote set to automatically lock the volume control strictly to the television. This will unlock all the volume controls to be independent. If you want to control the TV's volume, press "TV" first. If you want to control the cable box's volume, press "CBL" first. The following technique can be used to map an unused or unneeded button on the "silver" remote to the tuner swap command.

The Motorola DVR contains two tuners. Some versions of the "silver" remote lack the DVR-specific buttons, including the "swap" button that tells the DVR to swap the "background" tuner which can record but does not display on-screen with the "foreground" tuner the tuner that is actively displaying on your TV. A common use for this command is to switch to a tuner that is not currently recording a program in order to watch another live program without disrupting the ability to pause or rewind the first program.

To do this, simply:. The "SWAP" button at the bottom-left of the remote small black button with white lettering should now swap between your tuners. Additionally, the green "LIST" button in the middle of the remote control should now bring you straight to a list of your recorded programs, instead of having to navigate through a series of menus to get there.

For the silver Comcast remotes, you usually need to add two extra zeros to the front example: for second skip instead of the listed The top entry lets you see previews for some of them. NOTE: Captions may not show up until a timeshifting button e. A "macro" can also be created that will simulate hitting a series of buttons from the single press of a button. Note: Macros typically operate across any device selected Cable, TV, Aux unless you use keymap to force a code onto a key.

If that is done, the macro will not work for that device. Note: 15 buttons can be programmed to each macro. Macros cannot be combined, and the original function for a button is kept when used inside a macro. The following technique can be used to erase a macro programmed on a key. You are essentially creating a macro with no steps. Volume Lock is a remote control function that forces the volume and mute keys to always send the codes for your audio device typically the TV or an amplifier.

You can change what device is used for volume, or disable the feature. When disabled, the remote will send the volume code for whatever device is currently selected.

This will disable Volume Lock for all devices. The Volume and Mute keys will send the codes for the selected device. Some of these remotes also have a Channel Control Lock. The All On key is a built-in macro that sends Power codes for all 3 devices. This macro cannot be altered or removed. Due to bugs, it's often best to leave the DVR on all the time. Unfortunately, the All On macro will turn it off if somebody presses the button.

A workaround is to alter the code sent for the DVR's Power command to something that is ignored. That way, when the macro runs, it sends the unused EFC code. The drawback to this method is that the Power button will not work at all. There is a manual mechanical workaround to this issue. Using a box cutter blade or swiss army knife blade, cut the top rubber off the ALL ON button so it is flat to the plastic Do not pierce the rubber.

The button will still be usable but won't be likely to be pushed unless a dedicated "little pinkie" device is used. As a further enhancement a piece of tape can be place over the surface making the button effectively gone. If your remote is not acting right, or you've made changes and messed things up, you can reset the remote to defaults. This reset will delete all macros and keymoves, including volume and channel locks. It will not reset device codes. As indicated above, functionality may be lost after performing a factory reset.

Comcast URC-style remotes, for example, will no longer communicate with the set-top box after a reset and must be reconfigured. Comcast gives the following codes for Motorola digital boxes not dvr. Note for these codes to be entered the remote must be unlocked 4 blinks after entering :. Then, follow the normal programming procedure using the correct code as above for your set-top box.

To re-lock the Cable device code, repeat the steps above. EDIT: Kindly try the following codes: , , , , , for 'gray' remotes that use four digit codes. If you have another universal or multi-device remote that you want to use to control your Motorola DVR, you need to find the proper setup code.

General Instrument was bought by Motorola a few years ago; Jerrold was a former General Instrument brand. Many universal remotes or older cable remotes may not support the transport keys play, pause, etc If the cursor keys are supported, you can use them as alternates:.

If your remote doesn't support Day - for Stop, you can use Live Down to return to live video, then go through the menus to access the recording and delete it, restart from beginning, etc..
