Abstract: A method of decoding a picture frame from a bitstream includes grouping N tiles of the picture frame into P sub-pictures, the P sub-pictures being non-overlapping with each other, a first sub-picture of the P sub-pictures comprising Q columns of tiles, N being an integer exceeding 1, P, Q being positive integers, and partitioning a first column of tiles of the Q columns of tiles into M sub-slices, the M sub-slices being non-overlapping with each other, M being an integer exceeding 1. The method further includes obtaining first tile information from a memory prior to decoding a current sub-slice of the M sub-slices, a first processor decoding the current sub-slice of the M sub-slices according to the first tile information, and storing second tile information in the memory upon completion of decoding the current sub-slice of the M sub-slices.

Abstract: An embodiment disclosed a system for collaborative positioning calibration, comprising at least one reference station and at least one client. The reference station uses a known position and a satellite signal transmitted by at least one satellite to compute a pseudo-range difference of the reference station position and the satellite position, and then broadcasts an area calibration data including at least one pseudo-range difference to at least one client. Based on the area calibration data, the client computes at least one pseudo-range calibration data and outputs a calibrated position of global positioning system.

Abstract: A method for distributing workload among a plurality of servers each having a given workload capacity for providing a web service is provided. The method is to be implemented by a master module and includes the steps of: a) for each of the servers, determining a maximum allowable workload that is smaller than the given workload capacity; b) for each of activated one(s) of the servers operating to provide the web service, detecting a current network workload thereof; c) calculating an overall workload equal to a summation of the current network workload(s) detected in step b); and d) deactivating/activating at least one of the servers so as to adjust a number of the activated one(s) of the servers according to the overall workload calculated in step c), the current network workload(s) detected in step b), and the maximum allowable workload(s) of the activated one(s) of the servers.
