Improving VR Video Clarity: PPD, Tile Encoding, and Future Directions

VR video clarity suffers because the required pixels‑per‑degree far exceed what 4K or 8K spherical streams can deliver, but tile‑based encoding that decodes only the viewport, combined with low motion‑to‑photon latency, distortion control, advanced codecs and AI‑driven projection, promises sharper, lower‑bitrate 6DoF experiences.
