High Definition Multimedia Content Anyone?

Does the latest generation of downloadable high definition (HD) multimedia content worth viewing and hearing in our dedicated HD-ready home theater set-ups?

Nowadays, HD (high definition) multimedia content (audio and video) that can be downloaded from the net via your own home PC is of such quality that most of them-if not all- deserve to be viewed and heard in your existing HD-ready home theater system. If you’re like me – as most of anyone in the audiophile community- who thinks that your PC and home theater system should not mix (i.e. share the same outlet) because the former can degrade the performance of the latter must face a somewhat insurmountable problem. How to send that high definition movie -with the attendant surround sound data- that you legally downloaded from the net, from your PC to your home theater set up?

There are a number of systems in which you can deliver/send that HD content you have downloaded from the web. One of them is a relatively new technology - which uses your mains/ac line to send your data. Consumer devices that utilize this principle of sending data only came to the market near the end of 1997. So the ones currently available in your local AV/computer store not only works better, it’s likely to be cheaper as well thanks to almost ten years of progress. This has the advantage of avoiding the clutter that can be created when installing the necessary data-transfer cables. The problem with this system is that if you own a state-of-the-art home theater system, you probably bought with it a very good dedicated mains/ac line filter to maintain the consistently good performance of your home theater system while protecting it from electrical interference and lightning strikes. The same mains/ac line conditioner blocks the digital data that you intend to send down your mains/ac lines. Another way to send your multimedia data while avoiding the clutter of additional cables is via WIFI or wireless data transfer systems. The current generation of WIFI systems can easily handle the bandwidth required in sending HD multimedia content but will be easily vulnerable to signal interference especially if you use your mobile phone while using the WIFI system. If you want to maintain signal integrity while transferring HD multimedia data, Ethernet networks are a good choice. A word of warning though because these systems involve additional wiring if you are squeamish about the clutter factor. The latest “Cat 6” or category 6 high speed Ethernet connections are a good choice and could be a very good investment because of it’s future proof status. This is due to the fact that it can handle data transfer speeds of 10 Gigabits per second and anything faster is yet in the far off future.

I just hope that the circa-2007 PC and AV convergence will bear the fruits of a better audio and video quality that doesn’t cost the earth. Unlike the divergence of 10 or 15 years ago were hi-fi manufacturers have the luxury of producing and selling obscenely expensive AV equipment with impunity. Since all of our present media formats are digital in one form or another, convergence is inevitable due to the fact that digital data is both robust and universal.
