SDT 201 ARK-6
The New SDT ARK-6 Series is the result of years of research and rep¬resents the state of the art of the worldwide transmitter technology. We call it UNIVERSAL DRIVER because of its incredible capability to modulate in all schemes, just uploading a proper software package. It is perfect for both international broadcasters which have business in several countries – to increase manageability of investment through reduction of transmitter types - and national broadcasters, due for its versatility in operation modes and configuration. In fact it can be used as a transmitter, an heterodyne transposer, a re¬generative transmitter and Single Frequency Echo Canceller (perfect for Single Frequency Network), all in a single hardware. ARK-6 UNIVERSAL DRIVER is resilient to future evolutions of technology and standardization: this platform guarantees a perfect upgrade path for new modulation schemes that the researchers will delivery. Besides ARK-6 UNIVERSAL DRIVER already implements DVB-T/T2, PAL, ATSC/MH, NTSC, ISDB-T modulations. The SDT ARK-6 allows selection of transmission modes in various ways: remotely, using a dry contact; via SNMP commands; via TCP/IP, using the Web graphic interface; or even via a dedicated command inserted into the transport stream. Functional interfaces are available for total remote control of the appara¬tus by means of serial protocols or TCP/IP ports. Thanks to the internal Web server the apparatus can be easily monitored and configured and updated using a LAN connection and a standard Web browser. More¬over, the built-in SNMP agent allows full automated remote control.
