Patent number: 8249159Abstract: A scalable coder having a grid motion estimation and compensation module (110), a motion compensation temporal filtering module (105), a scalable coding module (115), a discrete transformation module (120), and a packetization module (135). The grid-motion estimation and compensation module (110) outputs a scalable motion vector from the source video data, supplied resolution and bit rate parameters. The motion compensation temporal filtering module (105) generates, from the source video data and the scalable motion vector, a residual image corresponding to the difference between the present and previous image frames. The scalable coding module (115) is coupled to receive and encode the scalable motion vector. The discrete transformation module (120) is configured to receive and domain transform the supplied video to a sequence of coefficients.Type: GrantFiled: June 23, 2005Date of Patent: August 21, 2012Assignee: Agency for Science, Technology and ResearchInventors: Zhengguo Li, Xiaokang Yang, Keng Pang Lim, Xiao Lin, Susanto Rahardja, Feng Pan

Publication number: 20100250804Abstract: A method of optimizing the usage of communication buses is disclosed. In this method, a slave may function, when necessary, as a ‘pseudo-master’. This allows direct communication between slaves, one of which functions as a ‘pseudo-master’. This hence relieves the Master device of the load required as an intermediary for the communication of said slaves.Type: ApplicationFiled: March 24, 2009Publication date: September 30, 2010Applicants: PANASONIC CORPORATION, PANASONIC SEMICONDUCTOR ASIA PTE., LTD.Inventors: Jan Pang Lim, Shao Shan Wu
