Overview

DTV Signal Generator is the professional solution to generate and record MPEG-2/ATSC/DVB/ISDB transport stream. DTV Signal Generator offers easy connection to various digital television signal sources and receivers, suitable for high-definition and standard definition digital television.

Especially, DTV Signal Generator has some special features for STB manufacture and development as below.

• Multi Port, Multi Use : 1~8 Signals can be generated simultaneously and controlled separately
• Memory Play : TS can be generated only on RAM Cache memory without accessing the Hard Disk

DTV Signal Generator is the world first MPEG2 Test Signaler built in modulator (DVB-S, DVB-C, DVB-T or 8VSB). With DTV Signal Generator, you can test MPEG2 TS directly on the set-top box anytime and anywhere. Most importantly, DTV Signal Generator has multiple I/O interface(ASI/SPI/SMPTE310M) supporting simultaneous play-out & record of 7 Input/Output transport streams. It will save your cost and time for buying several other TS generators.

In a Lab environment, DTV Signal Generator is the most flexible solution to set up DTV signal environment your engineers need. With various physical interfaces and multiple ports ( ASI / SPI / SMPTE310M / RF Out / RF In ), manufacturers can easily set up manufacturing lines. In addition to the basic functions for MPEG2-TS recording and playback, DTV Signal Generator has several enhanced functions for professionals.
