LG Electronics

is using the National Association of Broadcasters convention here to showcase present an assortment of new products and services based on the Mobile DTV (ATSC-M/H) standard it helped to develop.

To support the Mobile DTV broadcasts that are ramping up this year, LG is introducing a range of television receiver products that will fit in the palm of the hand.

Beyond delivering breaking news, weather alerts, and favorite shows, LG sees the new system being used to deliver both information and entertainment programming combined with up-to-the second social-networking updates, 3D telecasts, and electronic coupons that can help eliminate the newspaper clipping.

LG is showing a prototype 7-inch glasses-free (auto-stereoscopic) 3DTV receiver and a social network services application that lets viewers engage in Tweet-TV to interact with program content and submit comments on programs.

Broadcasters will consolidate real-time comments and transmit them along with the video and audio, as a transparent conversational overlay.

Viewers will be able to carry on an open discussion on a program or reply to questions asked as an audience quiz.

LG Electronics is also showing its first Android-enabled smartphone prototype equipped with Mobile Digital TV (MDTV) reception, offering conditional access functionality for future subscription broadcasts and the capability of receiving "non-real time" data including electronic coupons or "real-time" data reception with applications like Tweet-TV, the company said.

The demonstrations are being conducted with the help of Harris, which has developed the necessary MDTV transmission equipment, and local DTV broadcasters KLAS-TV, 8 News NOW in Las Vegas.

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 all three of the innovative applications for ATSC MDTV.

LG is demonstrating the new Tweet-TV mobile DTV application to present viewer tweets on MDTV handheld devices.

A Harris MDTV transmitter will deliver tweets that are received as data files and displayed in a transparent panel over a portion of the LG prototype Android smartphone.

The mobile 3DTV is being transmitted at the Convention Center to receivers throughout the North Hall. LG is displaying the signals on a 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 3DTVs.

The 7-inch barrier-type LCD display shows 3D images that are viewable with glasses. The device also receives conventional 2D 416 by 240 resolution MDTV broadcasts and scales images up to 800 by 480 resolution. It also functions as a digital photo.

To make electronic coupon demos possible from a smartphone, KLAS-TV 8 (RF channel 7) is transmitting digital coupons for electronics stores and restaurants during NAB.  

The smartphone prototype for both the electronic coupon and Tweet-TV demonstrations is LG's first full-touch CDMA device with built-in Mobile DTV circuitry.

It runs the Android 2.2 (Froyo) operating system and LG's second-generation MDTV chip. It is equipped with a 3.2-inch 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.

LG is also making a critical chip (the LG2161R) for mobile DTV reception. The single-chip design includes both the tuner and demodulator in a 7mm by 7mm square package. It is already being used in several mobile DTV receivers and will be found on many more coming out over the course of the year.
