Your TV Is Eating Your Frames
summary
Explains that TVs often break playback at the hardware layer: decoders stall on large keyframes causing dropped frames, bit rate is a poor capability signal, HDMI negotiation can falsely advertise codecs (HDMI handshake lies), and some TV boxes are effectively four times slower than phones. Describes a working measurement rig that encodes a frame-unique counter into audio and video and records the screen with a camera to detect drops and A/V drift, finds motion smoothing adds ~100 ms of video latency (audio lead ≈80 ms), and shows these issues are measurable and actionable.
