Traditional digital video link uses video compression as source coding, creating 2 challenges for channel coding. First, the compressed video stream is sensitive to transmission errors due to the use of predictive and variable length coding. Second, the data rate dramatically increases if the video content changes from frame to frame. The subsequent transmission errors make the entire received video extremely pixelated and blurry.
On the other hand, HDZero does not compress the video before transmitting. Its clarity depends on signal intensity and is unaffected by motion. In the event of any transmission errors, only select pixels are corrupted and the entire video maintains its overall clarity. In other words, transmission errors are isolated to pixels, rather than affecting the whole video.
