QAM
tA scheme of format conversion optical 16-ary quadrature amplitude modulation (16QAM) toquadrature phase shift keying (QPSK) signal based on cascaded four-wave mixing (FWM) in semiconduc-tor optical amplifiers (SOAs) is proposed. Theoretical analysis and simulations of the format conversionscheme are conducted to validate the feasibility of the proposal. In this proposal, the phase conjugatedof 16QAM signal is generated after the first FWM process in an SOA, and then the QPSK signal is con-verted due to the second non-degenerate FWM (ND-FWM) process in another SOA. The performance andthe optimal design of the 10 Gbit/s format conversion system under various key parameters of SOAs are uated and discussed. Simulation results present useful to enable interconnection between backbonenetwork and access network.

Video summarization refers to creating a summary of a video. Medical examinations like endoscopy and bronchoscopy lasts more than 20 minutes .The doctor may not have sufficient time to watch the entire video or the whole of video content may not be of interest to the examiner. Sometimes the medical video has to be sent to a specialist who is located at a distant place. In such cases, the doctor may just want to view the summary of the video instead of watching the whole video. Thus , the summary should be such that it should convey as much information about the occurrence of various incidents in the video.
Video summarization plays an important role in efficient storage, quick browsing and retri of large collection of video data without losing important aspects. It also reduces transmission bandwidth efficiently when need arises. Efficient summarization of video recordings of bronchoscopic and endoscopic procedures is also highly relevant for the development of medical video libraries.
