Audio and Video Management

Project by: Amber ImaiMentors: Tom Vermeulen & Bill Cruise

Advisor: Sarah GajadharCanada-France-Hawaii Telescope

Home Institution: University of Hawaii at ManoaUniversity of California Santa Cruz, Center for Adaptive Optics (CfAO)

Akamai Internship Program, Summer 2008

Overview

• OAP Design/Objective

• My Role in the OAP

• Work in Progress

• Concluding Statements

OAP Objective(adapted from the OAP Detailed Design, Audio and Video)

• Technical Advances and Observatory Efficiency

• No One at Summit• Easier Work Environment• Mechanical Failure• Solution:

– Need to monitor and remotely control observatory systems

– Can be done through sensors, programmable logic controllers, and WEBCAMS

What is in Progress for the OAP

• Software Infrastructure

• Remote Control of Mirror Cover and Cooling Systems, Telescope Control System, and Dome Shutter (to name a few)

• AUDIO and VIDEO MONITORING

My Role in the Project

• Creating the Audio Video Recording Server– Learn and Understand Linked Lists, Pointers,

Arrays, Strings, and Forked Processes

• Learn about Axis webcams– Axis 214– Axis 207

Work in Progress

• Addition of more cameras• Updating the camera webpage• Other sections of the OAP• Fully Remote Observing

Concluding Statements

• The OAP now has a specially designed server that will record and manage it’s space

• Store data for approximately 1 week

• AV Server COMPLETE!
