Capable of Receiving Terrestrial Digital TV Broadcasting"

Tokyo, July 10th, 2003- NEC Corporation announced today that it has developed the working prototype of mobile phone which is equipped with the receiver of terrestrial digital TV broadcasting.

In Japan, terrestrial digital TV broadcasting service will commence from December 2003 in major metropolitan areas of Tokyo, Nagoya and Osaka districts. After few years, it is scheduled to offer the programmes specifically targeted for portable terminals including mobile phones as part of the terrestrial digital TV programmes. With the availability of the service, mobile phone can receive not only the digital TV programmes, but also further attractive programmes with effective combinations of TV broadcasting and mobile communications, integrating services such as image, voice/sounds, data and mobile internet applications / services and content.

The prototype has been realized by employing portable antenna for digital TV broadcasting, UHF tuner, OFDM (Orthogonal Frequency Division Multiplexing) decoding LSI developed by NEC on 3rd generation (3G) W-CDMA mobile phone. The OFDM decoding LSI "myuPD 61530" has been developed by NEC Electronics Inc. in November 2002, which is the first in the industry. With this LSI, low-power consumption and ultra-small package has been realized.

"NEC is also leading digital TV broadcasting infrastructure systems vendor so this prototype is the integrated product of NEC's competences and know-how in mobile, digital TV broadcasting and electron device field,." said Yoshiharu Tamura, General Manager of NEC's Mobile Terminals Division.

NEC will further enhance the prototype improving its capability such as better receiver devices, lower-power consumption, and also develop characteristic digital TV/mobile internet integrated service applications, and detailed functions on mobile phone.

NEC will demonstrate the prototype at "Telecom 2003" held from Oct 4th 2003 at Geneva, Switzerland.

(*Note) OFDM
OFDM(Orthogonal Frequency Division Multiplexing)
OFDM is one of multi-carrier modulation method which distributes the data over a large number of carriers that are spaced apart at precise frequencies.
It is the modulation technique used for terrestrial digital TV broadcasting in Europe, and Japan
(*Major features of the prototype)
- Narrow band receiver for mobile service.
- UHF13from62ch
- OFDM decoding LSI (*2) for one segment partial reception (*1).
- Multiplexing system:MPEG-2 Transport Stream
- Visual codec:MPEG-4 Visual Simple Profile(*3)
- Audio codec:MPEG-2 AAC LC Profile

*1: Partial reception uses a dedicated segment, which is positioned to be the central one among OFDM segments. This segment is assigned for mobile service.
*2: The OFDM decoding LSI "myuPD 61530" has been developed by NEC Electronics Inc. in November 2002.
*3: MPEG-4 is applied to the prototype, tentatively.
