720P video capture compared on the HTC 7 Trophy, iPod Touch, Flip HD and many other devices

November 27, 2010 | By Surur

Nigel Parker have published this video comparing video capture on a variety of devices, including the iPod Touch, Windows Phone 7 HTC Trophy, Samsung PL150, Panasonic Lumix DMC-TZ10, Flip UltraHD, Flip minoHD, Nikon D7000 in 1080p, all shooting the same scene of Pleo toy in bright sunlight.

When comparing the 720p video of the iPod Touch with the HTC 7 Trophy, the video from the iPod Touch has less compression artefacts, but is a lot softer, while the 7 Trophy shows more detail, at the cost of some significant compression artefacts.

In the end however what is pretty surprising is that the result from all the devices look nothing like what one is used to on one’s 50 inch flat screen, making one wonder if HD video capture is in fact worthwhile on these mobile devices.

What do our readers think of the video quality on these devices? Let us know below.

HD video payback demoed on Windows Phone 7

September 12, 2010 | By Surur

We have seen many Windows phone 7 Xbox Live demoes, but increasingly we post them for features and functionality not related in any way to gaming.

In this video, at the 4:10 mark, we have a great demo of the Zune application playing Wildlife in HD, a 30 second 720p video with a bitrate of 5 942 Kbps, pretty comfortably.

We have already seen one device, the HTC T8788 being pretty media-focussed, so it is reassuring to see the platform can handle multi-media so effortlessly.

Thanks Mark Gibbs for the tip.

New HD video-out plug for phones in the works

April 15, 2010 | By Surur

Nokia Corporation, Samsung Electronics Co., Ltd., Silicon Image, Inc. , Sony Corporation and Toshiba Corporation today announced the formation of the MHL™ (Mobile High-Definition Link) Consortium to develop a new mobile audio/video interface standard for directly connecting mobile phones and other portable consumer electronics (CE) devices to high-definition televisions (HDTVs) and displays. The MHL standard features a single-cable with a low pin-count (and therefore smaller) interface able to support up to 1080p high-definition (HD) video and digital audio while simultaneously providing power to the mobile device. The MHL Consortium is also announcing the availability of an abridged draft specification available for review at www.mhlconsortium.org.

The MHL Consortium was established by the Mobile High-Definition Interface Working Group announced on September 28, 2009 and is responsible for developing, licensing and promoting the new mobile connectivity technology as an industry standard open to anyone desiring to become an adopter and enabling the development of compliant mobile and display products across a broad connectivity ecosystem. Products implementing MHL technology will feature:

· HD Video and Digital Audio

Consumers will be able to display HD video content with up to 1080p picture quality and digital audio from their mobile device on an HDTV.

· Low Pin-Count Interface

HD video and digital audio is transmitted via a low pin-count interface simultaneously providing data, control and power, which allows mobile devices to maintain their small form factor and keep implementation costs low.

· Provision of Power to the Mobile Device

Digital HD content can be output from the mobile device over a single cable while power is provided to the device. For example, a mobile phone can play back a full-length movie on an HDTV without draining power, so when the playback is completed the mobile phone can continue to be used for other purposes, such as calls and emails.

· Content Protection

High-bandwidth Digital Content Protection (HDCP) technologies protect high-value digital motion pictures, television programs and audio against unauthorized interception and copying.

Silicon Image had previously developed a physical connector on which the standard will be based, and importantly the connector was also compatible with the USB standard, making it useful as a general purpose connector rather than just a new mini-HDMI replacement.

Now that microUSB is just catching on, do we really need another connector? On the other hand, with our devices set to become particularly media-heavy, now may just be the right time. Let us know your thoughts below.
