GENERAL DESCRIPTION
The W99200F/ W99200AF is a high performance MPEG-1 Video Encoder which supports real-time video encoding. The W99200F/ W99200AF provides a fast, high quality and cost-effective solution for use in consumer video systems, PC add-in cards, and PC external boxes. It enables a wide range of applications including video and audio capturing, encoding and authoring for Security system, Web sites, RVCD, Digital VCR and video e-mail. The W99200AF also supports the cooperation with the Zapex Z1210, the MPEG audio encoder/ MPEG system mux chip. W99200F is functionally equal to W99200AF, excluding the cooperation support.
