What happens when a packet is corrupted in a JPEG2000-coded video?

When a packet is corrupted in a JPEG2000-coded video, the system allows for recovery of the picture as soon as the next keyframe arrives. JPEG2000, known for its efficient coding and error resilience, operates by compressing video into a sequence of frames, with keyframes serving as reference points. When a frame is corrupted, the decoder can identify this issue and rely on the information stored in the subsequent keyframe to reconstruct the video data accurately.

This means that while there may be a visual disruption during the corrupted frame, the video stream can resume normal playback using the data from the next keyframe. This recovery capability is a significant advantage of JPEG2000, particularly in environments where data integrity may be compromised, such as streaming applications over potentially unstable networks. Overall, the resilience of JPEG2000 against packet loss is what enables automatic recovery of video content, minimizing the impact of corruption on overall viewing experience.
