Video Format
LecCorder captures,
digitizes, and encodes audio and video recording of a class or seminar in
a high-quality, archival digital video format (MPEG1). The high-quality
MPEG1 video stream is stored, and automatically converted to an Internet-quality
media stream (H263). Standard codecs are used for video conversion. There
are no proprietary "black box" features in the LecCorder system.
Lecture Content
Along with
the audio/video recording, LecCorder also captures presentation content
delivered within a web browser. Powerpoint presentations stored in html
format, and standard web pages are two common presentation formats that
work very well with LecCorder.
LecCorder indexes the captured media streams, and synchronizes them with
the presentation material. In this way, the flow and tempo of the presenation
is preserved in the LecCorder playback.
Publishing
LecCorder
publishes all files needed to play back your lecture to a standard web
server. LecCorder publishes these files automatically, eliminating the
an error prone and time consuming process. LecCorder users can customize
templates for publishing their lecture. The user can select Internet-quality
or Intranet quality (or both) contents to be published.
Playback
For Internet
playback, LecCorder provides Java audio, video, and Web content playback
tools for asynchronous playback over the Internet. No plug-ins or helper
applications are necessary.
For Intranet and other high-speed networks, LecCorder provides full-screen,
30 frames per second VHS-quality video playback using Microsoft Media
Player.
