TECHNOLOGIES FOR STORAGE-EFFICIENT VIDEO ENCODING AND DECODING

摘要

Techniques for memory efficient video encoding and decoding are disclosed. In the illustrative embodiment, a video encoder of a compute node uses a lossy compression algorithm to store a reference frame of a video stream. The lossy compressed reference frame is then used to encode a subsequent picture of a video stream. When the corresponding decoder receives the reference picture, it applies the same lossy compression algorithm to store the reference picture. The lossy compressed reference frame is then used to decode subsequent images. Drift between the encoder and the decoder caused by compression of the reference frame can be avoided by using the same lossy compression algorithm at both the video encoder and the video decoder.
