| General Description |
The StraTek STP-300 transport stream player records and
plays back the incoming transport stream which derives from an MPEG-2 encoder,
DTV receiver, etc. With a 40 GB hard disk, the compact portable system can
record up to 280 minutes of DTV video clip in the form of the raw DVB,ATSC
transport streams(in case of 19.392Mbps), and can be retrieved later on
for viewing, enabling the so-called time-shifting. The playback output data
are available either at UHF channel 18 or 19. 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.
