PARIS - French Mobile TV chip specialist DiBcom has introduced a single chip that enables DTT (Digital Terrestrial Television)/DVB-T (Digital Video Broadcasting) reception on a personal computer.
DiBcom said its new chipset, dubbed DIB7770, integrates on a single IC an embedded RF tuner combined with a demodulator, linked to a USB 2.0 bridge. The so-called "3 in 1" solution was developed to make possible the design of small and affordable USB 2.0 TV accessories for high quality reception of digital TV, the company added.
The integration of the DIB7770 chipset goes beyond the main functions (tuner, demodulator and USB bridge) and includes SAW Filters and other discrete components.
The Paris-based company noted that the receivers, thanks to their linearity and sensitivity, "surpass the Nordig2 and MBRAI specification with a very low power consumption of less than 500mW" that is suitable for digital terrestrial reception (DTT/DVB-T) on PC’s, Ultra Mobile PC’s or Portable Media Players (PMPs).
Finally, DiBcom claimed the DIB7770 enables the design of USB 2.0 solutions for TV reception in UHF or VHF (dual-band tuner) and in either a single or diversity mode (dual antennas).
