Signal processing video: scaler, switcher, processore

Signal processing video

Processori video moderni gestiscono scaling, switching, multi-view, formato/HDR conversion. Componenti chiave: scaler, switcher, processor.

Scaler video: cosa fa

• Converte risoluzione input verso output target
• Es. 1080p in → 4K out (upscaling)
• 4K in → 1080p out (downscaling)
• Cambio aspect ratio (16:9, 4:3, 21:9)
• Frame rate conversion (50/60 Hz)
• Color space conversion (RGB, YUV)
• HDR tone mapping per display SDR

Switcher

• Routing source verso destination
• HDMI/SDI/DP input multipli
• Cross-point matrix
• Seamless switching no glitch
• Production switcher (Blackmagic ATEM)
• Install switcher (Crestron HD-MD8x4)

Processor video pro

• Multi-view layout (PiP, quad, 9-up)
• Edge blending per multi-projector
• Warping per superfici curve
• Color matching tra display
• Genlock per sincronizzazione
• Marche: Christie Spyder, Barco E2, Vista Spyder X20

HDR processing

• HDR10 / HDR10+ / Dolby Vision input
• Tone mapping per display SDR/HDR
• Metadata management
• Calibrazione gamut color

Frame rate conversion

• 50 Hz EU vs 60 Hz USA
• 24p cinema in 60 Hz output
• Motion interpolation
• Judder management

Use case
