Abstract (en)
[origin: WO2005086487A1] Video encoding and decoding methods and systems for video streaming are provided. The video encoding method includes encoding first resolution frames using scalable video coding, upsampling the first resolution frames to a second resolution, and encoding second resolution frames using scalable video coding with reference to upsampled versions of the first resolution frames.
