Entering the 21st century, the production environment and system of film art were very rapidly implemented from analog to digital. In such a process, the development and change of imaging technology have had a profound effect on the expressive modalities of visual aesthetics. However, in-depth discussions on how the existing analog aesthetic has been implemented into the digital environment are somewhat insufficient. In this study, Iwai Shunji's latest film , which continues to carry out remarkable creative activities across the analog and digital ages, specifically examines what 'Iwai aesthetics' he has pursued since the analog era is revealing in the digital age. Methodically, Iwai Shunji's transition from analog to digital age was examined and his digital film was approached and analyzed from three aesthetic perspectives : 'Light', 'Composition', and 'Space and Point of View'.

The TFRC is a congestion control mechanism which supports the requirements of video streaming applications and controls its sending rate by using the information such as loss event rate and RTT (round-trip time). However, TFRC has a performance degradation in wireless networks because it performs congestion control by judging all the losses occurred in wireless network as a congestion signal. In this paper, we propose new loss discrimination mechanism which is using ECN in order to solve the performance degradation of TFRC. Through the results of simulation, we proved that the proposed mechanism can improve the performance of TFRC.
