The display format formerly known as 4K will now be called "Ultra High Definition" in the home, the Consumer Electronics Association (CEA) announced in California today.

The CEA said it chose Ultra HD to denote that it has a higher resolution than the existing 1,920x1,080 pixels of full high definition.

To qualify as Ultra HD, a display needs to have a resolution of at least 3,840 pixels horizontally and at least 2,160 pixels vertically, the CEA said. Additionally, the product will require at least one 4K-capable digital input and display 4K content natively without … Read more

On one side, there's 4K: four times the resolution of your current TV. LG, Sony, JVC, and others have all announced or shown upcoming 4K displays.

On the other, there's OLED: Organic Light-Emitting Diode. Significantly better picture quality than your current TV, plus lower energy consumption, and even thinner cabinets.

So what's more exciting?… Read more

In a small room away from the main convention center at the CEDIA Expo, LG showed off its upcoming 84-inch 4K LCD, the LG 84LM9600.

I got a close-up look at the new ultraresolution panel, got a lot of questions answered, and got a rough idea what we can expect when it starts shipping next month.

Curious? I was too.… Read more

A week after Sony Chief Executive Kazuo Hirai uncloaked the company's massive 4K 3D TV, Sony has uncloaked its price, too: $25,000.

People can pre-order Sony's 84-inch XBR-84X900 today, but it won't be in stores until November, Sony said today.

The 4K TV has four times the number of pixels -- 3,840x2,160 -- as a regular HD TV. The 4K label, a bit of a loose term meaning 4,000, refers to number of pixels across the width. Sony is pushing hard to move the industry to 4K video, hoping for a new upgrade … Read more

Time to learn German for Wednesday's tech news roundup:

Sony has unveiled two of its biggest TV innovations of the year, and they're both inside the new XBR-84X900: it's the company's largest screen to date, and it's one of the first to feature 4K resolution.

The XBR-84X900 is the company's first 4K screen, and comes in the single 84-inch size. It's an edge-lit LED-based LCD TV that features passive 3D (another first for Sony) and comes with a 10-driver stereo speaker system.

A new compression technology represents a significant improvement over today's standard, a new study found. The result could help pave the way for video with at least four times the pixels of today's 1080p standard.

The new compression technology, called HEVC or H.265, is significantly better than today's prevailing standard video codec, called AVC or H.264, researchers from the Ecole Polytechnique Federale de Lausanne in Lausanne, Switzerland, concluded.

"The test results clearly exhibited a substantial improvement in compression performance, as compared to AVC," the researchers said. "As ultra-high definition television has recently … Read more

Sony plans to introduce a super-sized 84-inch LCD television during IFA 2012, Europe's major consumer electronics show, a source told CNET.

The source, who spoke on condition of anonymity, confirmed to CNET that the upcoming 84-inch TV can display a massive 3,840x2,160 resolution (four times the number of pixels in a conventional 1080p set), also known in the industry as 4K. We learned that the 84-inch Sony TV features a side-lit LCD panel (think thin) and removable speakers. In terms of design, our source describes the aesthetics as a reimagined retro-style appearance with a modern twist. … Read more

A trade show in September will be the coming-out party for video technology called HEVC or H.265, a new arrival in a hotly contested market for the best approach to compression.

HEVC, short for High Efficiency Video Coding, is for encoding and decoding video streams so they can be stored or transmitted more economically than today's dominant H.264, aka AVC or Advanced Video Coding. Specifically, HEVC allies say it can deliver the same quality video as H.264 with half the network bandwidth.

The codec has been in the making for years, but it's now almost … Read more
