Sony Japan tour on Bravia 4K & Magnetic Fluid Speakers

We spent the entire week last week doing the tour of Sony Headquarters in Tokyo, Japan to get a closer look at their 4K technology and its commercial application as well as a better appreciation of the Bravia 4K.

We’re already quite familiar with 4K TV from last year so the debate about full HD vs. 4K is mostly settled.

We’re already very used to display resolution in smartphones that go as high as 441ppi. For ultra HD TVs, the highest resolution we’ve seen so far is about 80ppi only. That’s for a 55-inch 4K TV with a resolution of 3840 pixels × 2160 lines (8.3 megapixels, aspect ratio 16:9).

4K resolution becomes more logical for display sizes starting 55 inches and higher. At 84 inch, a 4K TV will have a pixel density of just 52ppi while an equivalent 84-inch 1080p TV will only have 26ppi.

Second, there’s also the misconception that 4K TVs are useless if there are no 4K content readily available. The fact is, all photos taken with an 8MP camera or higher are already 4K.

Most 4K TVs, including that of Sony, have the ability up-convert 1080p content to 4K. The result is a significant improvement in sharpness, color and over-all picture quality.


A side by side comparison between a Sony 4K TV and a competitor’s 4K TV. The one with more vivid colors is from the competitor. While the colors are more saturated, it actually diminishes the detail of the subject.

To demonstrate this, the engineers down-scaled a native 4K video into 1080p. They then played the 1080p video on a 4K TV alongside a similar TV playing the original 4K video. The resulting picture are very close to each other, almost indistinguishable.

Sony’s Bravia 4K TV are also paired with their proprietary Magnetic Fluid Speakers. It was developed from NASA but is now being employed as a standard for Sony’s TVs and dedicated speakers. This unique type of speaker dampening also allows for a slimmer form factor aside from delivering better quality audio.

To demonstrate this, Sound Engineers from Sony showed us a setup in one of their Listening Rooms the internal parts of the audio board. They explained the difference from the old model and the new model and pointed out the new parts (bigger capacitors, higher impedance, etc) that help make the audio output better.

They then played various music files and allowed us to switch the output speakers. The same was done with the Magnetic Fluid Speakers. There was general agreement that the one with MFS has the better sound quality, providing much louder and clearer audio.

Sony sound engineers explained that both improvements were done in their Sony Bravia 4K TVs and even at maximum volume, the speakers on the 4K TVs did not budge, producing the same good quality audio without the cracking noise we’d experience with regular speakers.

One of the highlights of the tour was a showcase of their 56-inch Sony 4K OLED TV which they showcased on CES 2013. The TV was very slim and the picture quality was simply awesome.

The tour gave us better understanding of Sony’s 4K ecosystem and much appreciation for 4k technology in general. Too bad we weren’t able to take videos and photos of the many other interesting stuff inside their museum of tech.

Sony showcases 55 and 65-inch 4K TVs in Tokyo HQ

Sony invited us here in Tokyo to get a good tour of their offices and talk to key executives about their 4K technology. They also gave us an exclusive “The Square Tour” with all the gadget goodness though it’s unfortunate we’re not allowed to take photos or videos.

We’ve already had a several close encounters with the Bravia 4K before — first time was when we used it on the set of @geekynights last year (the 84-inch model worth Php1.2 Million) and the second time with these new models (the KD-X9004A) back in May at the Shang in Boracay.

While the original 84-inch model has been in the market for close to a year now, the move to take 4K closer to consumers is signified by the introduction of more conventional sizes like the 55-inch and 65-inch models.

I am told at least four (4) people in the Philippines have already bought the Php1.2 million 4K TV back in the Philippines. With the availability of the smaller-sized models, Sony is hoping to sell more of them 4K TVs in the country.

The 55-inch Bravia 4K TV sells for about Php299k while the 65-inch retails for Php399k in the Philippines.

These 4K TVs have 4 times the resolution of the regular full HD 1080p displays (that’s 3840×2160 pixels). That’s a resolution that is ideal for larger TV display sizes (55 inches and above).

Sony also showed us other more practical uses of their 4k technology, especially in broadcasting. They even attempted to put together three 4K video cameras to make one very high-resolution footage of a football game. This allows the broadcast to just capture and crop any 1080p frame within the entire footage without the need to pan and zoom into the field/stadium, thereby reducing the need or multiple cameraman setup.

Sony also demoed to us the CineAlta F55 and CineAlta F65 (pictured above) which are 4K cameras used to film the movie Oblivion and After Earth.

For the movie After Earth, M. Night Shyamalan picked out three of them CineAlta F65s as the main camera, each one costing about $77,000.
