CONFERENCE PROCEEDINGS FREE ACCESSThis paper presents a memory-bandwidth conscious HEVC encoding method that restricts the use of small-size inter-prediction blocks. As the number of inter-prediction blocks on sub-pixel positions increases, the memory-bandwidth associated with motion compensation process increases. When the high resolution videos such as 8K4K, 4K2K, and HDTV, are encoded and decoded, the memory bandwidth increase becomes a serious problem. The presented method prohibits the use of inter-prediction blocks which are smaller than 8x8. This restriction reduces the peak memory-bandwidth by about 60%. Simulation results for high resolution video sequences show that the restriction keeps coding efficiency loss less than about 1% and saves encoding time by 17%.View full abstractDownload PDF (641K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe are studying wideband modulation/demodulation technologies to realize system that can transmit non-compression high-definition television signal and the ultra high-definition television signal in wireless transmission of the broadcasting program materials. We developed a QPSK modulator and demodulator that used FPGA for the signal processing device. The modulator makes QPSK modulated signal by its symbol rate of 742MHz for 1.4835-Gbps HD-SDI signals. In this paper, we mention techniques for realizing high-speed wideband modulation and demodulation technologies, for instance, the features and the circuit configurations of the modulator and demodulator.View full abstractDownload PDF (880K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe push-to-talk communication line for broadcasting organization is used in VHF band (160MHz Band), and used for a way of communication in the program production. In this report, we designed a helical antenna with a metal case as a handy-type transceiver and calculated the characteristics of the antenna with a numerical human-body model. To investigate the influence of human body on the characteristics of the antenna, we calculated the antenna gain and radiation patterns when the antenna is in the close proximity to the face. As a result, we confirmed that the antenna gain and radiation patterns in the horizontal plane of the antenna degrade slightly with respect to them of the antenna located in the free space in case that the distance between the face and the antenna is more than 100mm.View full abstractDownload PDF (774K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe propagation measurement that measured the radio wave that reflected to the building was executed, and the polarized angle of electromagnetic wave was examined. And, the analyzable method of the arrival radio wave to which delay time in the same direction by the measurement of the polarization angle degree in addition to the analysis at delay time and the arrival direction analysis was adjacent was studied.View full abstractDownload PDF (1411K) -
