This is supposedly the year 3- D television becomes the hot new thing: Updated sets and disc players are coming out, and 3- D cable channels are in the works. But it's not clear the idea will reach out and grab mainstream viewers. Besides having to spring for expensive new TVs, people would have to put on awkward special glasses to give the picture the illusion of depth. That limits 3- D viewing to times when viewers can sit down and focus on a movie or show. It's one thing to put on 3- D glasses in a theatre, but "at home, you're with other people in the living room, running to the kitchen and doing other things," said Greg Ireland of the research firm IDC. Unfazed by the potential hang-ups, the biggest TV makers began revealing their 3- D models Wednesday before the official opening of the International Consumer Electronics Show in Las Vegas. Tim Baxter, president of Samsung Electronics Co.' s consumer division, said in an interview that 10 to 14 percent of the roughly 35 million TVs sold in the US this year will be 3- D-capable. Samsung is determined to make 3- D a big feature on its more expensive TVs this year. It's teaming with DreamWorks Animation SKG Inc. to make the Blu-ray 3- D version of the movie " Monsters vs. Aliens" an exclusive for buyers of Samsung's 3- D TVs. Panasonic Corp. said it will debut four 3- D sets this spring, but they won't be LCD sets, the most common type of flat panel. Instead, Panasonic is using plasma panels, saying the viewing quality will be superior to 3- D on LCDs. Sony Corp. said its 3- D sets will be out this summer. Some will come with glasses, others will be "3- D ready," which means that buyers will have to complement with a separate plug-in device and glasses for 3- D viewing. LG Electronics Inc. said it will introduce 47- inch and 55- inch flat-panel TVs with 3- D capabilities in May. LG didn't announce exact prices for its new sets. But Tim Alessi, director of product development at LG Electronics USA, said 3- D TV sets will likely cost $200 to $300 more than comparable flat- panel sets without 3- D capabilities, which already run more than $1 ,000. Even Vizio Inc, which is one of the TV market share leaders in the US but mainly sells inexpensive sets, said it would have 3- D capabilities on its larger, higher-end sets. Manufacturers aren't counting on 3- D to take over instantly. Colour TV and high definition caught on over many years. Like those earlier advances, 3- D programming requires upgrades throughout the TV and movie infrastructure, from shooting to editing to distribution. Incidentally, Samsung and Dreamworks are working with Technicolor, which pioneered color movies, to get 3- D right. Of course, movies in 3- D have been around since the 1950 s and from time to time have been billed as the next big thing in entertainment. And technically speaking, 3- D viewing in the home has been possible for the past few years. But there has been no good way to get 3- D movies and shows to watch. That obstacle is being swept away this year, as plans for a 3- D version of the Blu-ray disc have solidified. Players are expected this spring. Also, satellite broadcaster DirecTV Inc. said Wednesday that it will send out software upgrades to most of its set-top boxes in June that will enable 3- D reception. On Tuesday, two major cable networks - ESPN and Discovery - said they plan to start beaming 3- D entertainment into homes for the first time. ESPN plans to have its channel running in time to show World Cup soccer matches in 3- D on June 11. Discovery Communications Inc. will partner with Imax Corp and Sony to bring out its own full-time 3- D network in 2011. Samsung isn't waiting for 3- D programming: It said its sets will be able to convert standard 2- D programming to 3- D on the fly. The effect likely won't be as good as original 3- D footage, but it will "tide consumers over" until there is more 3- D programming, Baxter said. Toshiba is taking the same tack. It plans roll out a new line of five TVs this year that will perform the 2- D to 3- D conversion in a separate box with a powerful processor similar to one used in the Sony PlayStation 3. Like the other manufacturers, Toshiba didn't announce prices for the sets, but they will probably be expensive. TV manufacturers, movie studios and broadcasters are counting on the excitement around the latest wave of 3- D movies in theatres to finally drive interest in adapting the technology for the home. In particular, James Cameron's "Avatar" has set a new standard for 3- D in movies and has surpassed $1 billion at the box office. It demonstrates that 3- D is viable for more than just computer-animated children's or family movies such as "Cloudy with a Chance of Meatballs." "The hopes of the industry have undoubtedly been raised by the success of `Avatar,'" said NPD analyst Ross Rubin. But it's not clear people will be eager to pony up the premium prices for 3- D in the home - at least for a few years - or even that the experience will translate well from the movie theatre to the living room. (It is possible to do 3- D TV without glasses, but those solutions usually require viewers to keep their heads in one particular place. The image quality is also lower.)
