http://techluver.com/2007/11/12/sony...v-cable-range/ And this isn't even a complete set of cables. Computers are highly involved in many home enternatinment media systems, including the use Cat5+8P8C, eSATA, Firewire, and USB. Different cable types and different connectors are needed for different kinds of connections. You can't use HDMI, for example, to connect a hard drive to a PC. This results in waste, confusion, and in some cases price gouging. What we really need to have is a single type of cable with one common connector for everything. The digital world (and video is a part of that, now) is mostly going with serial bit streams. This one type of cable would then be used for any interconnect purpose: - PC to external disk drive - PC to video monitor - PC to PC - DVD player to TV - DVD player to PC - DVD player to DVD recorder (for your own content) - Camera to TV - Camera to PC Different kinds of signals would use different formats. The bit stream encoding should be the same (plus also have the original encoding as an option if the chosen standard is also an existing system, such as 75-ohm coax with BNC connectors which would also support SDI, NTSC, and RF). That doesn't necessarily mean 75-ohm coax is the best choice. There may be a better one instead. Feel free to suggest your best idea. But I think we need to have something chosen and encourage its universal adoption. While the industry that wants to gouge consumers may never play along with this, what is certain is if we don't try, there will never be a single simple interconnect between devices. -- |---------------------------------------/----------------------------------| | Phil Howard KA9WGN (ka9wgn.ham.org) / Do not send to the address below | | first name lower case at ipal.net / | |------------------------------------/-------------------------------------| |

I wonder if it would be economically feasible to route everything through a device via a fiber optic cable, either a single fiber optic or multiple bundle? Everything would be fed into a "router" where it would be sorted and sent on to each device. Just wondering. |

A good strong lightning bolt, or any surge, can travel through any kind of copper, and it will always find its way to the most expensive piece of equipment and kill it. Unfortunately, that is not likely to happen any time soon. Right now, it appears that most of the R&D is focused on wireless solutions. The good news is that wireless works just as well as fiber when it comes to reducing the probability of lightning damage and surges. The bad news is that no matter what the claimed bandwidth of any wireless solution, the actual bandwidth probably will be much less, especially as more devices crowd into the same frequencies, and it will have a hard time keeping up with the demand. Also it will have to deal with privacy issues and hackers. |

When we have every component of a home media system plus all the computers communicating with built in wireless, things are going to be a mess. Even one person can saturate the 2.4 GHz band in their home by themselves. What might be better for a lot of things is a cable-less optical system. That's not a solution for everything, since cable-less optical will need a line-of-sight path. But for things that stack together, having them interface each other via an optical window would work. Trouble is, there are unlikely to be any useful standards in this. So it's back to fiber optic. One thing I wonder is if making a single fiber bi-directional is practical at the consumer grade level (split wavelengths, not ping-pong). If the whole A/V industry can agree on standards, including the connector type, fiber size, wavelengths, encoding and modulation, then we could use ONE type of fiber cable for everything (meets my original goal). It should be auto-negotiated in some way. For example, when connecting two recorders so one can record what the other plays, or connecting two computers for any purpose, they should just settle on one wavelength for one direction and another wavelength for the other. That way we don't have to worry about separate input and output ports and making sure the are connected together in the appropriate way. Just one single fiber between devices should be enough. -- |---------------------------------------/----------------------------------| | Phil Howard KA9WGN (ka9wgn.ham.org) / Do not send to the address below | | first name lower case at ipal.net / | |------------------------------------/-------------------------------------| |

I certainly hope wireless never gets off the ground for this sort of application. I only fear that the market will be there for it because of people who are using their flatscreen TV as a fashion statement and don't want messy wires detracting from its beauty. Wireless does have a useful place in the household, and the things that can make good use of it shouldn't have to compete for bandwidth with things that should be using cables. Ever so slowly, hardware is getting smarter about dealing with cables. Most phones can now sense the polarity of the wires, so you no longer have to deal with touch tones that don't work because the wires are reversed. Computers and routers can now cope with crossover and straight-through cables. Many electronic devices can automatically handle 120 VAC or 240 VAC. I would guess that there are two main inhibitors to fiber. One is the cost. It may not be a lot, but with the intense price pressure on consumer electronics, even a few dollars might be too much. Cables aren't sexy (although Monster is working on that) so it's hard to sell the benefits of fiber. The other problem is the cables are fragile, compared to copper. It should be easier to agree on a standard though, because voltage and frequency will no longer matter. You'll just be moving bits, not electrons. But you know how these things turn out. Two consortia will form with different specs, they'll dig in their heels and try to pull other manufacturers into their camps, and the battle will begin all over. |
