http://tinyurl.com/av33w4x LAS VEGAS--One of the big problems with 4K TVs right now, aside from the fact that it's tough to discern any benefit from their extra resolution, is lack of content. Sony, alone among TV or content providers so far, actually aims to tackle that issue around the same time it launches its full line of 4K TVs later this year. This summer the company will set up a dedicated video distribution service to deliver 4K content to the home, complete with a hardware 4K Video Player that can feed the TVs directly. Currently buyers who pony up $25K for the company's 84-inch 4K TV are "loaned" a video player (essentially a big hard drive) pre-loaded with 4K video content, including ten feature films and a gallery of video shorts. But this is the first we've heard of a 4K delivery system and presumably it will offer access to significantly more 4K content, without the kludgy BD-ROM delivery method required to update content on the loaner player. In addition, Sony also announced a few Blu-ray discs newly remastered in 4K. Crucially, however, these won't be actual 4K Blu-rays -- they'll have normal 1080p resolution, and be playable by any normal Blu-ray player to any HDTV. Pricing for the 4K video player, the 4K content it would play, and the 4K-mastered discs was not disclosed, but it's safe to say none of it will be cheap. I also asked about delivery methods; hardware details; whether the content would be stored locally or streamed; compatibility with other devices; output formats; and whether content would be rented, owned or both. I was given no additional information beyond the company's press release: To my knowledge Sony's service will be the only way owners of 4K TVs (Sony or otherwise) will be able to view actual 4K content in the home, save that "loaner" and at least one minor exception. Given that a 4K Blu-ray standard has yet to be adopted; that there's no 4K broadcast standard yet for over-the-air, cable, or satellite delivery; and that there isn't even an official HDMI standard that supports the resolution, Sony's service will arrive remarkably early. Hopefully we'll be given further details later at the show. =========== 重點就是...Sony要推4K TV 然後,會有4K的影片BD重製......嗯 該不會BD-XL就是為此準備的 ? -- Plextor PX-760A CD-R專門 ───┐ Optiarc AD-7200S DVD燒錄 ───┤ Pioneer BDR-S05XLB BD-R專屬 ───┼應該不欠啥了!?
