Title: System and method for providing error tolerance, random access and rate control in scalable video communication
Inventor: ALEXANDROS ELEFTHERIADIS
IPC: H04N19/40
Filed: 2015-01-05
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for performing transmission with error tolerance, rate control and random access, in video communication using scalable video coding.SOLUTION: The error tolerance is obtained by using information from a low-resolution layer to conceal an information loss or compensate information of a high-resolution layer. The same mechanism is used for the rate control by selectively eliminating the information of the high-resolution layer from a transmitted signal which is compensated in a receiver using information from the low-resolution layer. Further, the random access or a changeover between low resolution and high resolution is achieved by using information from the low-resolution layer to compensate a high-resolution space layer packet which may not be received before changeover time.

Title: Global motion estimation processing method by local block matching, and image processing apparatus

Filed: 2015-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a global motion estimation processing method by local block matching capable of estimating a uniform global motion of an entire screen in a robust manner.SOLUTION: A weight coefficient is calculated from a matching residue of a result of local block matching. The weight coefficient is calculated from all the matching residues in a search region to generate weight distribution. Results in all pixels or all blocks of such weight distribution are cumulatively added. A peak value of the weight distribution in all the pixels or all the blocks that are cumulatively added is searched. A position of the peak value corresponds to a global motion vector amount. In the case where a global motion is a sub pixel, since a peak position is spatially spread, it is more preferable that a secondary function is substituted to a value of the weight distribution in a region near the peak position and that a position of a maximal value is defined as a global motion vector.SELECTED DRAWING: Figure 1

Abstract: PROBLEM TO BE SOLVED: To provide an outer rotor type synchronous induction motor in which the diameter dimension of a rotor core can be suppressed and magnetic saturation can be suppressed.SOLUTION: The rotation part of a synchronous induction motor has an annular rotor core 31, a secondary conductor, and a permanent magnet 33. The secondary conductor has a plurality of conductor bars 60 positioned in secondary conductor slots provided in the rotor core and a pair of end rings for annularly connecting the end parts of the plurality of conductor bars each other.

In addition, in this synchronous induction motor, the same poles of the permanent magnets adjacent to each other face each other in the circumferential direction. The magnetic flux of the permanent magnet flows out from the permanent magnet in the circumferential direction, not in the diameter direction. Therefore, magnetic saturation is hard to be generated even if there is no sufficient magnetic space on the inside of the permanent magnet in the diameter direction and the outside thereof in the diameter direction. Accordingly, the dimension of the rotor core can be suppressed, and magnetic saturation of the rotor core can be also suppressed.SELECTED DRAWING: Figure 4
