Abstract: A mobile wireless terminal is provided that controls a timing or a position in which handover is conducted between a plurality of access points, the terminal includes an antenna that receives a radio wave from an access point, a wireless communication interface that measures the radio wave, a processor, and a memory. The processor stores first and second received powers from respective first and second access points in the memory, conducts handover where a difference acquired by subtracting the first received power from the second received power is equal to or greater than a predetermined threshold, estimates a first available bandwidth before the handover and stores it in the memory, estimates a second available bandwidth after the handover and stores it in the memory, and controls a timing when handover of the mobile wireless terminal is conducted based on an available bandwidth difference between the first and second available bandwidths.

Abstract: An acquisition unit capable of providing more flexible services includes an acquisition unit that acquires a first stream; a transformer that transforms a first picture included in the first stream into a second picture, the first picture being irreversibly encoded, the second picture being reversibly encoded; and an output unit that outputs a second stream including the second picture.
