Merits of One-Seg

High quality video & audio in a mobile environment
Robustness to noise and multipath
Stable reception in a mobile environment
Easy to put the function on portable terminals
One-seg receivers need lower cost, smaller devices, lower power consumption, and lower CPU power than Full-seg receivers.
Various portable terminals get possible to have TV function.

- Frequency scanning / Channel list - Channel selecting - Audio/Video playing back - EPG (Electronic Program Guide) - Closed Caption / Subtitle - Data Broadcasting (BML) - Interactive service etc.
Mobile Reception Environment
1. 2. 3. 4. Lower electric field strength because of low antenna height (Approx. 10dB down) Smaller antenna gain because of a nondirectional antenna (Approx. 10dB down) Greatly affected by multipath fading because of mobile reception Doppler shift because of high-speed movement
Directional antenna Ground height 10m

Nondirectional antenna Ground height 1.5m

Improvement of Reception Performance
Improvement of a reception sensitivity with a single antenna almost reaches the limit.
Diversity reception techniques are expected to improve total reception sensitivity. In fixed reception, diversity effect is 3dB at maximum. But in mobile reception, e.g. in-car TVs or cell phone TVs in a car or train, the effect reaches 6 - 8 dB.
Overview of Diversity System
Ripples are generated because of multipath reception.

Experiments of One-Seg Diversity Reception
Experiment 1 : Field test A) The upper terminal is using single antenna reception system. B) The middle terminal is using diversity reception system of SANYO. C) The lower terminal is using diversity reception system of a certain company.
Experiment 2 : Laboratory test A) The left terminal is using diversity reception system of SANYO. B) The right terminal is using diversity reception system of a certain company.
Diversity Reception System for Cell Phones
Diversity systems are applicable to cell phones as well as in-car receivers. Now, only one product, P903iTV, is equipped with diversity system. It has two antennas for One-Seg, a whip antenna and an internal antenna.

About 35 million analog TVs will be persisted in Japan by 2011, when transition of analog to digital broadcasting will be completed, especially in the field of public institution (e.g. schools, hospitals, and nursing homes etc.).


Since 2003 various ISDB-T products, fixed, in-car and portable receivers have been launched in Japan. Consumer adoption of ISDB-T receiver is growing at a rapid pace for 2011 when analogue TV broadcasting will end in Japan. About 30% of cell phone users will have One-Seg cell phones in 2010 in Japan. For mobile reception, diversity techniques are very effective to improve the reception performance.
