Lecture capture is a process that recording classroom's teaching activities into digital format, do some processes & store it somewhere in cloud, so that students can then watch those videos over and over through their pc, laptop or other gadget at their own pace. Contents that were recorded are including lecturer's audio/video and any visual aid involved such as PowerPoint slides, laptop's on-screen activities, whiteboard and document camera.
Some technologies that we use to realize this idea are including cloud computing, server-client, databases, storage, compress/decompress modules, networking-things and higher level interface made by PHP programming language.
It is our mission to archive classroom teaching activities into a digital format that later can be reviewed or revised by students at their convenience anywhere and anytime.
Client software will capture classroom activities and automatically upload the raw data into the server for processing.
The server will do data processing, compression, indexing and storing to another server that will interface to end users. Client software is designed to make the capturing process become easier so that teachers can increase the focus on his teaching process, not to focus on how to use the technology.
We are still working on software development and product testing. Some bugs may need to be removed. Some features need to be included. We have also identified a private college that wants to implement this technology to archive their assets (lecture sessions). Our simple calculation, for one-month teaching sessions, for 50 lecturers, 8 hours daily, 1 hour per class session, 20 days a month, about 1.6TB contents will be archived or 20 TB a year! This college will own a unique digital library for their student and can enhance the teaching methods of their staffs.
