Samsung to offer a DVB-H chipset

Targeting the emerging TV-on-mobile market based on the DVB-H (Digital Video Broadcast-Handheld) standard, Samsung Electronics announced early this week a new DVB-H front-end chipset.

It includes a Zero-IF (intermediate frequency) cmos rf tuner and a channel decoder compliant with DVB-H and DVB-T (DVB-Terrestrial) standards.

Leading chip makers like Philips Semiconductors, Texas Instruments and Motorola are rushing to the DVB-H market with promises to deliver by as early as late this year a combined DVB-H receiver/demodulator. Some single-chip solutions would be based on system-in-package (SiP) technology. So far, different vendors are offering separately either a tuner or a channel decoder based on DVB-H.

Samsung hopes to put a stake in the ground on the DVB-H market by offering a chipset based on two separate ICs. The Korean semiconductor company claimed that the two-chip solution will help mobile phone vendors shorten design cycles by allowing them to "forego compatibility testing and chip interface adjustments between the RF tuner and the channel decoder."

The chipset includes a CMOS RF tuner dubbed S5M8600 and a DVB-H/T channel decoder designated S3C4F10. The baseband channel decoder is a system-on-chip featuring a CPU and embedded memories needed for Link Layer operations such as MPE-FEC (multiprotocol encapsulation-forward error correction) decoding and IP decapsulation.

Samsung's Zero-IF CMOS RF tuner chip supports DVB-H networks internationally. For mobile phones designed to handle planned broadcast TV service in the United States, the tuner operates in the L-Band (1,670MHz to 1,675MHz) frequency range. For those targeted at Europe, it also will function within the European UHF frequency range (470MHz to 890MHz) and the L-Band spectrum likely to be allocated for European mobile TV broadcast (1,452MHz to 1,477MHz).

Separately, Samsung said it will introduce its dual-mode solution supporting both terrestrial DMB (Digital Multimedia Broadcasting) and DVB-H standards by mid-2006. The global DVB-H market is expected to grow rapidly, from 5 million units in 2006 to more than 50 million by 2008.

Startups such as DiBcom in France are leading the emerging DVB-H market with demodulators. DiBcom's demodulation chip, often paired with a separate tuner IC developed by companies such as Motorola, is being used in a number of international DVB-H trials.
