The chip takes the I/Q data from ADC and performs the necessary sampling and time/frequency correction, de-interleaving, demodulation and decoding, and provides DVB-H, T-DMB or CMMB transport stream. The design challenges come from optimization for power and die size as well as re-configurability to allow easy performance tuning and other broadcast standards support. ASTRI’s approach is based on its high performance DVB-T/H and T-DMB single-mode chipset design expertise to design the multi-mode chipset by leveraging its innovative IPs and custom processor to achieve the high performance, low-power consumption and cost-effective Multi-mode Mobile TV Demodulator Chipset to serve the industry. |
