The Death Of HD-DVD May Not Save BluRay

February 18th, 2008

Toshiba’s impending announcement that it is ending production of HD-DVD players, crowns BluRay as the next-generation DVD format champion. It may, however, be a pyrrhic victory and High Definition DVD’s may be an evolution in video player technology that simply gets leapfrogged.

Travelling in China some years ago, I noticed the prevalence of VCD, at a time when the developed world had largely migrated from VHS to DVD. DVD was only beginning to catch on in China at the time. I realised that there were a couple of reasons for this. A dearth of interesting Chinese broadcast TV meant that the recording capabilities of VHS were not required. But also, it seemed as if VHS had been too expensive in China whilst it was growing in popularity in the West. When the Chinese could afford these sorts of devices, VCD was the latest and greatest technology and was widely adopted.

Meanwhile in the developed world, VCD never really took off. With relatively little quality improvement over VHS, there was not a compelling reason to adopt the standard. Consumers were happy enough with VHS. Similarly LaserDisc was skipped until DVD came along.

Skipping a generation of technology seems to be quite common, with less developed markets being out of sync with the developing world’s cycle. So whilst we skipped from VCD and LaserDisc to replace our VHS systems with DVD players, the Chinese adopted DVD quite a few years later.

Similarly in audio technology, some technologies have been skipped, such as MiniDisc, in favour of MP3 players. The US adopted analogue cell phones and took a long while to adopt digital mobiles, whilst analogue never really got going in Europe and the developing economies. 3G does not seem to have captured the market’s imagination, as the iPhone’s use of EDGE’s “2.75G” technology demonstrates.

Whilst there are some features to the various technologies that help to explain this, it also has a lot to do with entrenched technology, and with the next generation not providing enough of a step change to unseat the incumbent. The market needs bigger changes in convenience and capabilities before moving forward en-masse.

High Definition for Television programming is not particularly compelling. Is there any need for HD when watching Lost, 24 or Prison Break? Few are going to purchase a BluRay player and spend extra for buying or renting TV shows in BluRay format.

This leaves Movie sales and rental. HD does offer a significant improvement in video quality over DVD. However some of that advantage is lost, with a large number of HD TV’s only being capable of 1080i or less, rather than the full 1080p. The mere fact that there is such a confusion of choice over display resolutions, input cabling, viewing angles, contrast, brightness and life span for many flat panel displays, makes for a very consumer unfriendly market place.

In contrast, Apple has patiently waited for average broadband speeds in the US to rise to the point where downloading 720p feature length movies is viable. With recent studies showing that BluRay provides only slightly better quality video than Apple’s movie rentals, BluRay’s major selling point is less compelling. With having to go to a physical store, or waiting for it to be sent through the post, BluRay compares poorly in terms of convenience.

Apple’s Video rental DRM restrictions may seem weak relative to Netflix keep-it-for-as-long-as-you-like approach. But, as has been suggested elsewhere, Apple’s service is effectively video-on-demand in all but name.

Apple’s aggressive price cut on the AppleTV, significantly reducing margins, is a shot across the bows of the BluRay consortium. BluRay backers will need to bring player & content prices down rapidly to ensure widespread adoption. Unfortunately for BluRay, the next year or two will see improved networking bandwidth and with it a likely increase in Apple’s video resolution, removing BluRay’s key selling point, altogether. BluRay’s backers, however, may not appreciate the threat and will, I suspect, rest on the laurels of their success over HD-DVD. BluRay players are still expensive, and are likely to remain so until the 2008 holiday season, at the very least.

BluRay has only a limited amount of time to establish itself as the replacement for DVD, before the inevitable migration to internet distribution for video. The long battle with HD-DVD may have forestalled any chance of High Def DVD becoming widely adopted. I predict that BluRay, despite a lot of press and winning its battle, will run out of time and will be leapfrogged by more convenient, consumer friendly, internet distribution.

Yes, We Can

February 12th, 2008

In the unlikely event that you have not seen this yet (7m already have, in just 10 days), Black Eyed Peas’ Will.I.Am and friends put Barack Obama’s words to music. “Yes, We Can” may take on as much importance as “Ask what you can do for your country”.

Mac OS X: Home of the Web

February 12th, 2008

Lost in the mists of time and in the obscurity of a niche platform, many do not realise that the Web was invented on a NeXT machine running NEXTSTEP (whichever form of capitalisation was prevalent at the time). And that NEXTSTEP is the precursor to Mac OS X. The MAKE blog has some photos of the NeXT machine that hosted the world’s first website.

The first browser, WorldWideWeb, was written in the precursor to Cocoa, the tools used to create most of the great, new, software on the Mac, including Differencia.

As I mentioned in “Web 0.9 beta“, Tim Berners-Lee always envisaged the web to be read/write, presaging Web 2.0, as can be seen in this screen-shot.

What is fascinating is that if you read the text in the about box, you can see that Berners-Lee already had the concept of helper applications. In this case, specifically for a NNTP news-reader, presaging RSS links on pages being opened by a third party news reader application such as NetNewsWire or NewsFire.

I used to be surprised that Apple did not make more of its Web heritage, but I guess you cannot really say much about how great your current products are, based on a third party product developed 17 years ago for a platform created by a company that you paid $400m to do a reverse take over of yourself.

Comparing Address Book & Contact Data with Differencia

February 6th, 2008

Getting the template database off to a start, I have added templates for the contacts lists from all the major Mail clients. Layout Templates for Apple’s Address Book and the Contacts for Entourage, Thunderbird, Eudora, Outlook for Windows, Gmail, Yahoo! Mail and Hotmail can all be found in the new Address Book category of the template database.

Instructions for how to export contact information from each of these systems can be found by in the detail of each template in the online database.

Apple Address Book

Apple’s Address Book cannot currently export directly to a flat file format that Differencia can import. However Address Book can export to the standard vCard format with files with extension .vcf. There is an excellent utility on the web that will convert vCard files from any source into flat file formats that Differencia can handle. The Address Book templates in the database are based on the output from this vCard Format Converter.

The VCF Converter is quick and reliable and none of your private contact information is ever stored or available to the website running the converter. The converter can be found here.

NB. You will need Differencia 1.0.3 or later to make use of these templates.

Future Directions

Comparing Contact information provides some fascinating challenges for a comparison and reconciliation tool such as Differencia. In the future I hope to add some intelligence to Differencia with regard to contact data so that it can:

  • Make a probable match between “Mr J Smith” and “John Smith”
  • Understand international & area codes, so that a Home Phone of “+1-408-555-1234″ is the same as a Home Phone of “5551234″ for someone with a Home Address in Cupertino, CA, USA.
  • Add support for direct access to Apple’s Address Book, without need for conversion
  • Direct support for vCard (vcf) and LDIF files

We would appreciate any further feedback on how we can improve Differencia, so feel free to contact us.
