Webcast with DPS Systems

Video has exploded onto the Internet recently as faster connections have become more common.

Computer Film Services (CFS) systems allow users to make video files directly from the Timeline in several streaming formats, including the two most popular - RealMedia and Windows Media Format. The user can then place these files on a server and incorporate them into a Web page so that others can play them at any time.

Live Web Broadcasting (or live Webcasting) is the ability to broadcast playback from a computer (with CFS systems, directly from the Timeline), sending the output to a streaming server in one of the two supported Web streaming formats.

Others can watch the video, accessing the same location on the same server simultaneously, as it is broadcast. With CFS machines, it is possible to switch Timeline playback from pre-recorded material to live feed from a camera (or any other input device).

For example, a news programme could combine a live clip and a Webcast and make this immediately available via the Internet. Or, a university might use Webcasting and a live feed while a professor is giving a lecture to make this available on the Internet for distance education.

Key Features and Benefits:

  • Simultaneous archive during live broadcast - Post the archived file to your Website after the broadcast making it available for viewing at a later date.
  • Use Live Clips during Broadcasting - Switch Timeline playback from pre-recorded material to a live feed from a camera. Live clips may be mixed with pre-recorded clips on the Timeline.
  • Integrated editing - Prepare sections of the Timeline with titles, effects or special transitions from live clips to pre-recorded material to be broadcast as they play back.
  • Multiple bit rates - Cater for different users with customisable bit rates for Real Movie and Windows Media Files.
  • Choice of format - Multimedia output formats include RealVideo (RM), Windows Media Format (ASF or WMV and WMA), QuickTime (MOV), MPEG (MPEG 1 and MPEG 2), and AVI files.
  • Choice of resolution - Stream video at a multitude of resolutions, including full CCIR601 PAL (720 x 576) at 25 fps (20 MB/s) or NTSC video. Typical Web video resolutions are available, such as 160x120 to 352x240, with 320x240 being the most popular resolution for high bandwidth playback.
  • Filtered Scaling - Includes the ability to hardware-scale full-sized video to smaller resolutions. Scaling is filtered to ensure the highest quality output
