Multiple description coding (MDC) is a potential solution for video transmission over error-prone networks because it shows promising enhancement of error resilient capability. The MDC systems encode a single video stream into two or more equally important independent sub-streams, called descriptions. Therefore, if some of the descriptors get lost,(More)
Mobile 2.0 is being considered as a natural extension of the Web 2.0 revolution to the mobile networks. One important concept in Web 2.0 is the real-time creation and uplink transmission of rich multimedia contents from individual clients to the Internet. However, due to power constraints of mobile handsets, it is difficult to turn this concept into(More)
Palette mode is the new coding tool that has been adopted in the Screen Content Coding Extensions of High Efficiency Video Coding (HEVC SCC). Palette mode can represent colour clusters for screen content efficiently and can be summarized into two parts: palette coding tools and colour index map coding tools. This paper proposes two techniques to improve(More)
Palette mode, as a new coding tool, is adopted in the Screen Content Coding Extensions of High Efficiency Video Coding (HEVC SCC) that is being defined by the Joint Collaborative Team on Video Coding (JCT-VC). In the palette mode, pixels in a coding unit (CU) are represented by selected representative colours according to the characteristics of screen(More)
