Abstract: Embodiment of present disclosure relates to a Universal Serial Bus (USB) hub for switching downstream ports between host mode and slave mode comprising upstream port connectable to host port of host, downstream port and switching module. The downstream port is connectable to device port of peripheral device and acts in host mode and said device port acts in slave mode. The switching module comprises master port, switching port and control unit. The master port is connectable to upstream port. The switching port is connectable to other end of downstream port, the switching port acts in host mode. The control unit receives switch command from host to switch downstream port from host mode to slave mode; switches switching port to slave mode and enables downstream port to act in the slave mode when host emulates functionality of slave mode as required by peripheral device using vendor specific USB class.

Abstract: The proposed Dynamic Motion Vector Analysis method applies to the motion compensation module of a video decoder system. The method analyzes the motion-vectors of a given region of picture frame and outputs a set of regions to be fetched from the reference frames stored in the external memory. The size and number of regions are decided by a hierarchical method that uses a set of user-defined input thresholds. Pre-processing of the motion vectors associated with the given region allows the method to handle reference data to be fetched from multiple reference frames in the same framework. A complementary dynamic batch (region of operation) size strategy that works along with MV-analysis is also proposed to help utilize the on-chip memory resources more efficiently.

Abstract: A method, system and apparatus to seamlessly manage and access files across multiple devices in a network, comprising steps of maintaining a local database in each of the devices, synchronizing the local databases of the devices using transaction logs and sync controller, managing and accessing file(s) among the devices using the database.
