Abstract: A method for streaming video in a varying bandwidth through scalable multi-level video coding, including: providing at least two compressed video streams, each stream including a respective plurality of Inter-frames; encoding at least one Inter-frame of each respective plurality at a respective quantization using an Intra-Block Refresh mechanism; creating at least one switch frame between any pair of the compressed video streams; and creating a mixed stream using any pair of compressed streams and the at least one switch frame.
