MS1825 Multi-Function Video Processor

The MacroSilicon MS1825 is a multi-function video processor integrating four independent HD audio/video inputs, four independent HD audio/video outputs, a 24-bit digital video input or output interface, and one I2S / SPDIF digital-audio input or output. It can process interlaced or progressive digital video and graphics input, and includes four independent video playback engines for PIP, POP, multiview display, and system-level video processing.

Video Processing

• Supports VESA and CEA-861-F video formats.
• Supports RGB / BT.601 / BT.709 colorimetry.
• Supports SDR and DDR data transfer modes with 500 mV signal range.
• Automatic input mode, video timing, and InfoFrame detection.
• HD 1080i to 1080p conversion and SD NTSC / PAL to 480p / 576p conversion.
• Independent horizontal and vertical scaling, plus flexible frame-rate conversion.
• Edge-correction deinterlacing, global noise reduction, and 3:2 / 2:2 pull-down detection.
• Brightness, saturation, contrast, and hue adjustment.
• Input auto EQ, programmable EDID, programmable input HPD, and automatic output HPD detection.

Typical Applications

• Multiview display and PIP / POP video processors
• Multi-input, multi-output display control systems
• Embedded display products requiring a digital video input or output interface
• Video systems requiring OSD, scaling, deinterlacing, and frame-rate conversion

Design Notes

• MS1825 is suitable for systems that need 4-in / 4-out HD channels plus a digital video interface. For larger OSD font storage, embedded DDR, or more audio channels, evaluate the MS1826 series.
• Validate 4K@30Hz, color depth, color format, input/output combination, and digital-interface mode against system bandwidth, PCB design, and firmware configuration.
• EDID, HPD, EQ, frame-rate conversion, and OSD behavior should be confirmed with MacroSilicon reference material and project validation.
