It's not as simple as making a cable that fits. Digital audio cables and digital signals, both coaxial and optical, require a digital input. You need to convert the digital signal to analog to work with older receivers. These are available (Google Digital to Analog Converter or DA Converter). Just about every device that has a digital output will also have an analog stereo output, which will work with your old gear.

Is digital audio output the same as earphones?
Not in the least! Your first clue might have been that the connectors don't look anything alike. Earphones are on a 1/8" or 1/4" STEREO (3 conductor) plug and take an analog signal.Digital outputs are for connecting digital components together. Say you had a top-of-the-line 7.1 receiver but kind of an older, low cost CD player. Obviously, on a "cheapie" they didn't spend a lot of money on the section that converts it from Digital to Analog. The Analog is what you hear. You might remember how aweful it used to be in the old days when you would make a copy of a copy of a copy of a cassette. lots of hiss - no dynamic range. Well, now you could copy a CD "ad-infinitum" without losing a bit of information. So, if the CD player is accurately reading the CD, the digital stream on a $50 player should equal the stream of a $500 player. Take advantage of the fancy receiver and do the conversion there and things will sound MUCH better.The same thing if you got one of those "cheapie" government subsidized DTV boxes when they cut off analog television signals a few years ago. The audio is very harsh out of those. If you happened to get one with a digital out though...When it comes to Blu-ray, you could have as many as 8 analog audio outputs that would need to go into your receiver. Using quality cabling, this could cost quite a lot - maybe 1/2 as much as your player did! This could all be replaced with one digital audio cable. Multiple streams get "multiplexed" much the same way that your cable company can put over 100 channels on one wire or fiber-optic line.
Why wont your s video cable work between your projector and tv?
Your TV is unlikely to have a S-Video output to go to the projector. What most TV's had was a S-Video input, to come from a Super VHS VCR or older generation gaming console. If indeed the TV has a S-Video OUTPUT, and the projector is set to the correct input (usually this has to be changed in the input menu) and you are still not getting any picture, I would check the S-Video cable for bent pins. The cable's pins are very thin and can easily be bent or broken off with rough handling.
What types of operating systems are needed in a computer forensics lab?
A digital forensic lab should make use of multiple operating systems and hardware configurations because of the possibility of not only examining newer digital devices, but legacy equipment as well (yes, there are C64s still in use). Not all forensic tools are capable of capturing images, or performing analysis, from older operating systems and hardware - a well equipped digital forensic lab should keep working images of older operating systems to mitigate the possibility of being unable to acquire data. Apple's OS is a great foundation because of the Unix underpinnings, and the availability of many vetted open source tools, but DOS and Windows have powerful commercial tools as well. No one platform or tool is better than the other - the best tool is simply the one that works for the job at hand.
What is the difference between a data projector and an overhead projector?
A Data Projector (referred to as Digital Projector) is a projector that gets its image from a Digital Source, such as VGA (computer), RCA (the most common A/V input), S-Video (another form of video input), and some others. These projectors are most commonly used along with DLP or LCD Technology.An Overhead Projector is an older style of projection, common in Education (Schools). These projectors are totally manual and require you to put a transparent image onto glass to project the image overhead.
Which wires are live neutral and earth in a cable that is black white and green and can you use this cable in the UK?
This could be a USA-coded cable. If so then black is Live, white is Neutraland green is Earth.No, this cable cannot be used in the UK.In the UK:Protective earth (PE or E) - Green with Yellow stripes (in older wiring just Green) Neutral (N) - Blue [in pre-2004 fixed wiring Black]Live or Line (if single phase) L - Brown [in pre-2004 fixed wiring Red]Lives or Lines (if 3 phase)L1 - Brown, L2 - Black, L3 - Grey[in pre-2004 fixed wiring: L1 - Red, L2 - Yellow, L3 - Blue]Where the pre-2004 and post-2004 colours are both in use, take greatcare to ensure that all conductors are correctly identified.
Do old TVs get digital cable?
Older TV can receive digital cable although they may not display in HD
How do you connect your Laptop to the Audio Video slots on an older non HD TV?
You would need a red, yellow, white audio video cable.
What is an optical digital cable?
It is a fiber optic cable carrying a digital audio signal. The common brand name of the cable is TOSLINK (the TOS being Toshiba who developed it). The red light that you see is a red LED being pulsed on and off very quickly (usually 44,100 times a second). All digital information is transmitted this way. Digital only has two states: 0 or 1, on or off, hence light or no light. This is the optical version of the coaxial digital output (an orange RCA jack). The format itself is known as S/PDIF (Sony/Philips Digital Interface Format). In most cases, there is no quality difference between optical and coaxial. The only difference is that light is not a physical connection with a wire. It is rare, but "ground loops" (hum) can occur on any wired system where the components are on different electrical systems. Optical is impervious to this anomaly. There is also an older standard called ADAT which uses this same cable. The ADAT was an Alesis Digital Audio Tape(deck) which has 8 channels of digital audio and was popular in the late 80's. Although the decks haven't been made in many years, many other audio companies have adapted it as a standard for passing 8 channels of audio at once. This is pro use stuff (like in a recording studio).
How digital cable TV works?
A signal is sent through the cable at a much higher frequency than regular cable. Additional data is sent in this signal to support the original audio and video signals to ensure that they are received in much better quality than analog signals. This additional data and the type of signal sent is what allows the quality to be so much better than older analog signals.
I have the Transformers 2007 2-disc special edition DVD it has only 5.1 audio is there a way I can convert the 5.1 aduio down to 2.0 dolby surround audio with a special software?
You don't need special software. All DVD players downmix the 5.1 audio track and output it via the RCA analog stereo audio outputs for use with older Dolby Surround receivers.
Is it possible to use any surround sound system to hook up my ps3 and tv 2?
The optical output of the PS3 can be connected to older surround sound receivers. Newer receivers can be connected with the HDMI cable.
What are the technical specifications of AV cable?
An AV cable is an audio/visual cable that is used to carry sound and visual information. The older style AV cable had three leads, the newer AV cables contain five leads and are typically used with newer electronic items. AV cables have a variety of connection options depending on the items to be connected. An HMDI is a single cable that provides an audio/video connection with a 340MHz band width, which supports 10,12 and 16-bit colour.
What is the difference between a coaxial and audio video cable?
A coaxial cable sends all signal down one line. All the color, brightness and audio is piped together to the television, where a signal converter is required to separate all the information to be displayed on screen. An audio/video, or RCA cable (Red-White-Yellow), separates the signal into three parts, video, the left audio channel, and the right audio channel. The TV then has to only convert the video signal into the colors and brightness. Since the audio is already separated from the video with the audio/video cable, there is one less conversion needed at the TV. This allows for better picture quality with audio/video cables. To put a number to it, audio/video cables give 20% better quality signal that coaxial. S-video is even better as is separates the video signal into color and brightness. Component is better yet, as it separates the colors from each other (Red, Green, Blue) and sends the brightness with the green signal. These are all analog methods of providing a television with signal. Digital methods like DVi and HDMI provide the best signal quality of all.
Why have you been told that you need a cable box to continue receiving some of your channels?
In North America and Europe there are moves in progress to stop analog television broadcasts in the coming year or two. 2010 is the cut off year for the US and 2012 for the UK. By that time, all television broadcasting will be digital. Older televisions do not have digital receivers and so will not be able to use digital broadcasts directly. There are a number of ways to continue receiving television even with an analog television. While it is not true of all retailers, some are using the changeover to drive sales of specific products that will generate the most profit for them. It is important that you do the research to find out what options are available to you and which channels will be received on each platform. Here are some options for receiving digital television: Digital terrestrial broadcasts can be received by a digital television (all new televisions in 2010 have digital receivers fitted) or they can be received with a digital set top box (known in the UK as a Freeview box). The available channels may vary from one region to another so you will need to find out your local service. A set top box can be bought for £20 in the UK and $30 or so in US stores. Satellite receivers can be used (Direct TV among others in the US and Sky in the UK) Most packages require a subscription but there are free channels on satellite platforms. In the UK, Freesat is a publicly funded platform that offers subscription free services including HD channels. The last option is cable. Virgin has most of the UK market for cable and there are numerous cable providers in America. Each has its own package of channels with a wide variety of prices. The choice of platform and vendor is down to price and channel requirements but there is absolutely no requirement to have cable to continue receiving television broadcasts.
Do you have to buy an HDTV TV or will the cable companies be supplying conversion boxes for older TVs?
If you have cable, you will not need a conversion box. The analog-to-digital transition in the US in 2009 only affects over-the-air broadcasts. Cable operators will continue to provide analog service for years to come.
Can digital switchover work on older televisions?
Older televisions can make the switch to digital programming with a digital converter. The converters are usually about $20-$60 and are available at most electronics stores.
What is a built-in ntsc atsc qam digital tuner?
An NTSC/ATSC/QAM digital tuner, in the case of a TV, means that the TV supports the NTSC, ATSC, and QAM broadcast standards with its included tuner. NTSC is the old analog over-the-air (OTA) standard, ATSC is the newer digital over-the-air supporting High Definition video and Dolby Digital AC3 audio, and QAM means that the TV can decode digital cable signals without a set-top box. My internet research indicates that QAM will receive unencrypted broadcasts only. While encrypted channels varies by geography, it seems that most cable stations are encrypted while major networks are not. So, best I've determined, is that if you want more than just the major networks in high def you still need the set-top box or Cablecard.
