6 Video Formats and Standards
The Lecture Recorder x2 supports broadcasting of various standards and formats.
The choice of video format will depend on the broadcast content and performance
requirements. For example, Motion JPEG does not support audio from an external
source. It also depends on how the intended viewers are planning to receive and
play the broadcast. Keep in mind that browser viewer capabilities and
compatibilities are subject to change.
With the Lecture Recorder x2, video codec for streaming is selected by an
administrator. After this action the system creates a list of available streaming
formats for this codec. Users can view the broadcast in any available format
depending on their preference. Moreover, multiple users can view the same
broadcast in different formats. The list of formats available for the selected
combination of video and audio codecs displays on the Info page of the Web admin
interface.
The Lecture Recorder x2 can stream video using Flash (H.264), ASF (MPEG4 or H.264
codecs), Motion JPEG, RTSP (MPEG4 or H.264 codecs), or MPEG-TS (H.264). A quick
definition of these video streaming methods and the type of application that a
viewer would use to watch that particular video stream is now provided.
