有支援RM與RMVB格式的audio codec

jacky002

目前我有找到一家chip有支援的公司: http://www.amlogic.com/technology01.htm
請問是否有其他家的chip有支援RM與RMVB格式的?

Hw/Sw co-design is the better solution for multi-standard codec.

It's a reconfigurable codec chip , that is for different system customer, it reconfigure the codec what they need.

問題是系統商要考量的不只是硬體成本, 還要考量權利金成本
6 v0 E/ C. C6 s9 g# T晶片商盡量將各種Codec做進去, 僅半成品, 無權利金成本
系統商轉化成商品, 權利金都跑出來了, 但又未必用得到所有Codec
之後晶片商是否又會被系統商要求客制化?

感謝三、四樓的的資訊，看完了C2 Micro的solution不禁讓我汗顏 (流冷汗中 .... )。

其實應該是指可以解 RM / RMVB的 DSP or Co-processor，我已經找到possible solution.
