Since Apple unveiled its iTunes Music Store in spring 2003, bloggers have batted around the idea that the company chose the name cleverly -- because "Music" could be changed easily to "Media" when it started selling online movies. Three years later, although movies have not yet appeared on the iTunes site, it has sold more than 15 million digitized TV shows and videos (for $1.99 a pop), with the blessing of ABC, Disney, Showtime, NBC, MTV, and other providers
Not surprisingly, then, the success of these online TV shows and videos has accelerated speculation about movies. Last week, Variety, Forbes, and MSNBC all ran stories about rights and pricing negotiations between Apple and the major movie studios. The consensus: It's just a matter of time before iTunes starts selling feature-length movies, if not this year, then in 2007
For Internet video distributors, though, the Motion Picture Association of America has been a tougher nut to crack than television studios, because the film industry is more concerned about piracy
Aside from the wrangling over copyright and digital-rights management, though, technical problems also stand in the way of an iTunes Movie Store. Actually, it's one key technical issue. While Apple already has a high-profile storefront, marketing mechanism, and suitable file format for delivering movies, figuring out how to deliver these massive, multi-gigabyte files remains a challenge
Whether a consumer has a dialup or a broadband connection, it takes only a few minutes to download a song from iTunes. The Lord of the Rings trilogy would be several thousand times larger -- yet have to be downloaded at the same rate.
Choosing a file format carefully can mitigate the problem, but only somewhat. Somethimes you may need some professional converter softwares to do this job. Xilisoft supports Apple products very well ,such as Xilisoft iPod video converter ,which converts almost all popular video files to iPod video such as AVI to iPod, MPEG to iPod.
Otherwise, Apple owns the QuickTime format, whose latest QuickTime 7 Pro version, includes the H.264 compression/decompression standard, which is also used in the new generation of Blu-ray and HD-DVD formats. It compresses data into a much smaller space than the MPEG-2 codec used on DVDs.
As a result, a DVD-quality movie rendered in H.264 will take up half as much room on a disk drive and be twice as quick to download. (The H.264 standard is also designed to allow viewing at many different scales, from low resolution for 3G cell phones and video iPods to high-definition versions with 1,080 lines of vertical resolution.
