1. Circuits and device: Adopt new and original packing PHILIPS video Chipset; Choose high quality device such as TA capacitance and SMD-OSC to guarantee the stabilization and layout of the card.
2. PCB: Optimizing design, clear audio & video signal without disturbing: Much thicker copper layer improves heat conduction largely, it can guarantee excellent heat emission without radiater; Connecting finger twice gilding thickness than the one in normal technics, good anti-oxidation, to make device run much longer.
3. A/V lines material and interface: Copper BNC interface, its stabilization in connection is much better than normal interface's made by zinc; 30-lines shielded wire video transmission line with high quality; Adopt thicker gilding thick in DB connector.
4. Quality detection: Both card and A/V lines must pass strict detection before on sale.
