Summary
A visualization of the PAL PPU's video output signal, using different colors to denote each part of the signal. Based on Ntsc_video_timing.png.
The video output of the PPU is delayed by 1 pixel clock in relation to the working PPU memory. In addition, the active video portion is delayed by another 1 pixel clock. Cycle 0, scanline 0 according to the PPU Frame Timing Diagram is marked by the black pixel.
- Cyan is the horizontal blanking pulse
- Dark blue is the "back porch" after HBlank
- Yellow is the colorburst signal
- Red is the visible output region, including the left and right border
- Bright red is where the background and sprites are actually visible
- Dark red is where the border crops into the active video output
- Orange is the "front porch" before HBlank
- Magenta is the vertical blanking pulse
- Dark green is the surrounding black border, vertical blanking region, and the sync separator
