Patent ID: 8606025

Claim:
An encoding method, comprising: encoding an I-frame image to obtain a first reconstructed image; wherein the I-frame serves as a random access cut-in point; encoding an image between the I-frame image and a recovery point to obtain a second reconstructed image; refreshing the second reconstructed image to obtain a first refreshed image; wherein the first refreshed image is independent of the image content before the random access cut-in point; and encoding a corresponding image at the recovery point by using at least one of the first reconstructed image and the first refreshed image as a reference image; wherein the method further comprises: storing the first reconstructed image and the second reconstructed image into a first reference buffer; storing the first reconstructed image and the first refreshed image into a first refreshing buffer; and replacing the image in the first reference buffer with the image in the first refreshing buffer before encoding the corresponding image at the recovery point.
