Winbond Electronics W99200F, W99200AF Datasheet

MPEG-1 VIDEO ENCODER W99200F/W99200AF

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.
