SDT 501 ARK-6 ATSC COMPACT
The New SDT ARK-6 Series is the result of years of research and represents 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 regenerative 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 apparatus 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.
