Live Broadcasting

Caltech AMT has been providing online rich-media content in various formats since 1999. We currently use the Echo360 platform for lecture capture and Caltech's Ustream and Facebook channels for live streaming of events such as lectures, workshops, and conferences. 

Contact AMT to assist in choosing the best way to broadcast your event live and to provide an estimate.

Lecture capture solution for automated recordings with minimal editing. Delivered as streaming Flash video or on-demand video for computers and mobile devices. This lecture capture system currently does not support live broadcasts. Caltech has three appliances: 105 Annenberg, Hameetman Auditorium, and AMT's mobile unit.

Echo360 records a presentation's audio, video, and projected visuals and delivers them online as: streaming rich-media Flash presentation (as seen in the image above), audio with slides (H.264 format for iTunes), and audio only (.mp3). Chapter markers allow viewers to jump to points of interest within a presentation. Links can also automatically publish to Moodle, iTunes U, and an rss feed. Presentation files can be burned to a CD-ROM or DVD-ROM for platter distribution.

This method of recording lectures is ideal for ongoing lectures series and courses with minimal or no editing.

Caltech uses Ustream for live broadcasts. Visit Caltech's Ustream channel to watch some of the live-recorded events.


The Ustream platform allows for a large audience to view your event in real-time on computers (Windows, Mac, and Linux) and many mobile devices (iPhone, iPad, and Android) with free Apps. Online audiences can feel connected to the event by participating in the live chat next to the stream. During several Caltech lectures (including a Caltech course), the presenter answers questions from the online audience.

Examples of events AMT has broadcast live include TEDxCaltech, Caltech Commencement, CS 156 Machine Learning Course, Bloom Energy Press Release, Astronomy Hubble Fellows Symposium, Kavli Nanoscience Symposium, Wouk Lecture, and TIAA-CREF events.

Summary of legacy live broadcasting and lecture capture support

Caltech AMT has been providing online rich-media content in various formats since 1999.

Caltech's first live streaming platform used the Real Media format. The first broadcast was held on January 21, 2000, of President Clinton's National Nanotechnology Initiative announcement at Caltech's Beckman Auditorium.

Caltech's first rich-media online presentations used the SMIL (Synchronized Multimedia Integration Language) programming language to synchronize video, audio, and images into an integrated multimedia presentation. This content was delivered via Caltech's Streaming Theater.

The first adopted hardware lecture capture solution was Sonic Foundry's Mediasite appliance with the accompanying processing and cataloging servers. Over 300 hours of recorded presentations from courses, symposia, meetings, special lectures, JPL/Caltech workshops, and internal announcements were available in the rich-media catalog.

AMT no longer offers Real Media, SMIL, and Mediasite solutions and has moved forward with other platforms such as Echo360, Ustream, Caltech on iTunes U, and Caltech YouTube for recording, broadcasting, and hosting rich-media content.
