General Description
The StraTek STP-100 transport stream player records and plays back the incoming transport stream which derives from an MPEG-2 encoder, DTV receiver, etc. With a 20 GB hard disk, the compact portable system can record up to 129 minutes of DTV video clip in the form of the raw ATSC transport streams, and can be retrieved later on for viewing, enabling the so-called time-shifting. The playback output data are available either at UHF channel 14 or 15. Furthermore, the stored stream data on a PC can be transferred to the hard disk in STP-100 for recording . The system also provides stored materials that can serve DTV demonstration or presentation purposes to the audience in a cost-effective manner.
