LAS VEGAS, Jan. 5, 2011 – The first mobile digital TV that displays three-dimensional (3D) images broadcast via the ATSC Mobile Digital Television Standard is being demonstrated by LG Electronics at the 2010 International CES® here this week. The prototype 7-inch receiver is designed with auto-stereoscopic capability that eliminates the need for special viewing glasses to see stunning 3D TV images.

In addition, to show how local TV broadcasters can now offer more than just linear TV channels, LG Electronics is showing its first Android-enabled smartphone prototype equipped with Mobile Digital TV (MDTV) reception, which offers conditional access functionality for future subscription broadcasts and the capability of receiving “non-real time” data such as electronic coupons.

The demonstrations are made possible through a cooperative effort with Harris Corporation, which has developed the necessary MDTV transmission equipment, and local DTV broadcasters KLAS-TV, 8 News NOW in Las Vegas, and Vegas PBS Channel 10.  Roundbox, a leading mobile software provider, is providing non-real time data services that power the Smartphone coupon application, as well as the Electronic Services Guide (ESG) for both innovative applications for ATSC MDTV.

“The ATSC Mobile DTV standard offers broadcasters remarkable flexibility to address the changing demands of consumers and advertisers,” said Dr. Skott Ahn, president and chief technology officer, LG Electronics, Inc. “As broadcasters continue their national rollout of Mobile DTV, LG is proud to lead the transition with the latest innovations in mobile DTV services like 3D and non-real-time applications.”

Glasses-Free 3D Mobile DTV
In the Las Vegas demonstration, PBS Channel 10 (RF channel 11) is the first U.S. broadcast station to transmit 3D images via the ATSC Mobile DTV Standard. Receiving the signal is LG’s prototype receiver built around the LG2161 demodulator chip and LG-exclusive 3D formatting circuitry that combines the side-by-side left and right images for seamless viewing without the need for 3D eyewear commonly used for 3D TVs.

The seven-inch barrier-type LCD display shows lifelike 3D images that appear to jump right off the screen.  With its built-in antenna, the device also receives conventional 2D 416×240 resolution MDTV broadcasts and scales images up to 800×480 resolution. It also functions as an attractive digital photo frame when not being used as a Mobile DTV receiver.
“Broadcasting 3D mobile DTV shows television stations how flexible the ATSC Mobile DTV standard is and, perhaps more importantly, shows retailers and consumers a cool new application for mobile DTV,” said Jay Adrick, vice president of broadcast technology, Harris Corporation, which co-developed the ATSC MDTV standard with LG Electronics and Zenith.

Electronic Coupons from your Smartphone
Non-real time services such as electronic couponing and video-on-demand are made possible by the versatile ATSC Mobile Digital TV standard now being deployed by broadcasters throughout the U.S.  KLAS-TV 8 (RF channel 7) is transmitting digital coupons for electronics stores and restaurants during CES.

“Software advances are helping to drive exciting new applications like non-real-time mobile DTV broadcasts,” said Peter Mataga, chief technology officer at Roundbox. “LG’s latest smartphone mobile DTV prototype is the first to show how electronic coupons can be delivered by local broadcasters. It’s especially significant that Roundbox and LG have achieved interoperability in a way that conforms to the new ATSC Non-Real-Time Content Delivery Candidate Standard.”

The smartphone prototype is LG’s first full-touch CDMA device with built-in Mobile DTV circuitry.  Running the Android 2.2 (Froyo) operating system and LG’s second-generation MDTV chip, the fully-featured Smartphone includes a 3.2” HVGA screen, 3 megapixel camera, GPS and Wi-Fi capability, and other features such as an accelerometer, digital compass, and ability to play back a variety of audio and video codecs.

Chips Available for Portable Device Manufacturers
Co-developer of the technology at the heart of the ATSC Mobile DTV Standard, LG Electronics is producing the critical component for Mobile DTV reception – the LG2161R single chip design that includes both the tuner and demodulator in a tiny seven-by-seven millimeter square package.  This key component of mobile DTV receivers already can be found in a variety of new products being introduced by various manufacturers this year for mobile DTV, from laptop USB accessory receivers to prototype netbooks with integrated mobile DTV tuners.

Standardized by the Advanced Television Systems Committee and formally adopted as the ATSC Mobile DTV Standard, the new technology allows broadcasters to use a portion of the existing 19.4 Megabit-per-second DTV channel capacity to transmit data with extremely robust characteristics suitable for mobile, pedestrian and handheld applications.  The mobile DTV signal is also compatible with 8-VSB DTV, which was also developed by Zenith, LG’s U.S. research and development lab.

True Mobile Digital TV (MDTV) means watching live Digital TV (DTV) on mobile devices_RealtyGo_blog

What mobile DTV (MDTV) is?

Which networks can deliver true DTV experience to mobile devices?

True Mobile Digital TV (MDTV) means watching live Digital TV (DTV) on mobile devices,

with a user experience similar to the one the consumers are used to on their home TV. This

means having a big variety of shows to watch, with high quality high frame rate video and

quick response time for channel switching. While there are elements in the market that try to

confuse true MDTV with other forms of TV/media distribution that offer poor quality video

and a poor offering of channels, true MDTV is distributed through a dedicated broadcast

MDTV network.

Soon real estate professionals will be able to stream their live events and seminars through MDTV channel outlets, keeping consumers up to date on current events within their general areas. Imagine getting updates from destination places around the world, Vacation rentals for lease and a tour performed by the actual owner or representative. Choosing you vacation destination in the near future may become more real than ever before. Rest assure, RealtyGo will be looking into this futuristic type channeling to deliver real estate listings and information as efficiently as possible for everyone using Mobile devices.  Keep a look out for MDTV and a new technology boom; does Youtube ring a bell… .

The most common alternatives of DTV distribution to mobile devices are to get the DTV

content through the WiFi network or through the cellular network.

This article explains the different available methods, why the true MDTV experience can be

achieved only by a dedicated broadcast MDTV network and how the MDTV offering can be

broadened by wise usage of all the methods for distribution of DTV, which can provide the

best value and best user experience to the consumer.

1 Methods for Mobile DTV distribution

1.1 Distribution of Mobile DTV through the cellular network

The cellular network is conceptually a unicast network, meaning that the content is

transmitted to each receiver individually, even if several receivers are consuming the same

content simultaneously. Thus with the current deployed and used technologies, distribution

of mobile DTV content through the cellular network is no different than the distribution of any

other data through the cellular network.

There are some technologies for broadcasting content over cellular networks, including

Multimedia Broadcast Multicast Service (MBMS), Integrated Mobile Broadcast (IMB), and

Evolved MBMS (e-MBMS) for LTE networks. These technologies are currently either not

mature yet or not widely used (i.e. deployed). Nevertheless, though currently cellular

networks use unicast transmission for distributing DTV content, this article refers also to

optional future usage of these broadcast technologies.

The main concern that is related to mobile DTV distribution is its relatively high bandwidth

requirement. Watching live DTV content at good quality on mobile devices requires

continuous reception of streaming audio/video (A/V) content at a rate of about 500Kbps.

This reception rate enables the display of good quality video at QVGA resolution and at a

frame rate of 30 frames-per-second (FPS).

In developed countries, current cellular networks are already congested with the increase of

video consumption (YouTube, etc.), live gaming, web surfing and other data-consuming

applications over mobile devices. These networks do not have the bandwidth to provide live

DTV services with a similar user experience to stationary DTV in terms of video quality and

content variety. Recent testimonials to this problem were made public by AT&T, which is

now setting a cap for its subscribers’ data usage, since they need to “ease the congestion”

consumption-for-new-smart-phone-users /).
