Stream using Universal Plug and Play (UPnP) and Session Announce Protocol (SAP)

Use UPnP or SAP to stream to local SmartTVs or set top boxes

  • Media players, smart TVs, and set-top boxes can play live streams and saved recordings from the Lecture Recorder x2 via UPnP or SAP.
  • Streaming via UPnP and/or SAP is perfect for situations when the space in a lecture theatre is limited. The lecture can be streamed to other classroom locations on campus to handle student overflow.

Video encoding with H.264, MPEG-4, and MJPEG

  • Lecture Recorder x2 supports the most widely used video codecs to ensure maximum compatibility with commercial viewing software media players such as VLC and Adobe Media Player.
  • Multi-encoding provides an optimal combination of settings to ensure your stream reaches your audience.
  • Use the default settings, or fine tune the operation to your application.
  • Video frame rate, encoding bit rate, and key frame interval are among several parameters available to tailor the encoding to your specific requirements.
  • Whether you are recording highly dynamic full motion video or slowly changing instrumentation displays Epiphan Broadcasters enable you to direct the encoder to achieve optimal video quality while satisfying bitrate and file size constraints of your specific application and environment.

Video encoding

Supports audio codecs MP3, AAC and PCM

  • Lecture Recorder x2 supports the most widely used audio codecs to ensure maximum compatibility with commercial viewing and post production software.
  • Use the default settings, or fine tune to meet your requirements.

Audio encoding

Simultaneous recording and streaming

  • Lecture Recorder x2 can simultaneously stream and record your content.
  • Stores the video files to an internal drive with 16 GB of storage. Supports .AVI and .MOV formats (common and easy to use formats).
  • Admin interface indicates the amount of free storage space.

Storage space

16 GB of onboard file storage

  • Stores the video files to an internal solid state memory, with 16 GB of storage, in AVI, MPEG-TS or MOV format (common and easy to use formats).
  • Automatically deletes the oldest recorded file when disk space runs low and replaces the file with a current file to ensure the latest recordings are available.
  • Manage the size of your recorded video files by configuring the Lecture Recorder x2 to start a new file based on a time or file-size limit. When the limit is reached, the current recorded file is closed and available for download while a new file is opened for continued recording – all without missing a frame.
