There’s a good chance that the best picture you can put on your HD screen doesn’t come from your cable or satellite TV company, but from your new HD camcorder. As time and markets march on, that chance will only get larger. That’s because the there is a trade-off between the number of channels carried and the quality of each channel. To squeeze in more channels, the carrier squeezes out picture quality through compression. The result is “artifacts.” See here:
The titles get “jaggies,” the football field gets pimples, and everything gets blurred and/or re-painted by he compression algorithm as an approximation of the original image.
Carriers compete more by the number of channels they carry than by the quality of each channel. (There are exceptions to this, but on the whole that’s the marketing think.) Meanwhile your camcorder quality only goes up.
And as camcorder quality goes up, more of us will be producing rather than consuming our video. More importantly, we will be co-producing that video with other people. We will be producers as well as consumers. This is already the case, but the results that appear on YouTube are purposely compressed to a low quality compared to HDTV. In time the demand for better will prevail. When that happens we’ll need upstream as well as downstream capacity.
So here’s a piece in Broadband Reports that shows how carriers can be out of touch with the future, even as they increase the capacities of their offerings. An excerpt:
In upgraded markets, Comcast is not only upgrading existing speed tiers ($42.95 “Performance” 6Mbps/1Mbps and $52.95 “Performance Plus” 8Mbps/2Mbps tiers became 12Mbps/2Mbps and 16Mbps/2Mbps), but is adding two new tiers to the mix ($62.95 “Ultra” 22Mbps/5Mbps and the aforementioned $139.95 “Extreme 50” 50Mbps/10Mbps).
One recurring theme we’ve seen in our forums is that the new speeds have many users downgrading. In both forum threads and polls, many customers on Comcast’s 16Mbps/2Mbps tier say they’re downgrading to their 12Mbps/2Mbps tier — apparently because they don’t think an additional 4Mbps downstream is worth $10. Customers used to be willing to pay the additional $10 for double the upstream speed, but there’s no longer an upstream difference between the tiers.
That last line is the kicker. Comcast apparently still thinks that downstream is all that really matters. It isn’t. For anybody producing a lot of photography or video, upstream not only matters more, but supports activities where the user can see the difference.
In fact there isn’t a lot of perceived difference between 12Mbps and 16Mbps on the downstream side. Either is fast enough for a YouTube video. But on the upstream side, you can see the difference. In my case, that difference appears in the progress bars for pictures I upload to Flickr.
A few months ago I upgraded my Verizon FiOS service from 20/5Mbps to 20/20Mbps. The difference was obvious as soon as it went in. The difference will be a lot more obvious to a lot more people once those people start sharing, mashing up and co-producing higher-definition videos.
