RENESAS TW2828-BA2-CR

TW2828 is a display and recording MUX chip with HD SPOT capability designed to work with popular H.264 CODEC on the market today. TW2828 provides a clean and cost effective MUX solution to the multi-channel PC HD DVR marketplace. On the embedded DVR market, using TW2828 in conjunction with a host SOC can deliver the most cost effective solution on the market.
