Descriptions:

The STV6400 is a single-chip video decoder designed for converting analog video signals (CVBS or S-Video) into digital YCbCr format. It integrates an analog front-end, a digital decoder, and a chroma/luma processor, making it suitable for video capture applications in set-top boxes, video surveillance, and multimedia systems.

Features:

• Automatic Standard Detection: Detects NTSC, PAL, or SECAM signals.
• Adaptive Comb Filter: Improves luminance/chrominance separation.
• Programmable Brightness, Contrast, Saturation, and Hue Control.
• Vertical Blanking Interval (VBI) Data Extraction: Supports closed captioning (CC) and teletext.
• Low Power Consumption: Optimized for embedded applications.
• Integrated Sync Processor: Horizontal and vertical sync extraction.

The STV6400 is now considered a legacy product, and STMicroelectronics may recommend newer alternatives for modern designs. For detailed datasheets, refer to ST’s official documentation.
