Screen Map and Standards-Based Progressive Codec for Screen Content Coding

摘要

Methods and systems for delivering screen content to a client device are disclosed. One method includes, for each of a plurality of coding units corresponding to screen regions included in a screen at a particular time, classifying screen content included in the coding unit as having a content type selected from among a plurality of content types, at least one of the content types comprising a screen image type, and, based on a determination that the screen content has a screen image type, applying a progressive standards-based encoding to the screen content of that coding unit. The method also includes transmitting encoded screen content for each of the screen regions to the client device.
