Outline

The Xielide XLD3301B DVB-C (QAM) modulator is a high performance modulator developed according to DVB-C (EN300429) standard which is the standard of the European broadband satellite telecommunication. This unit provides a more powerful receiving ability to receive TS coming from encoder, multiplexer, DVB gateway, scrambler and etc. The output content carried by RF can be alternated between ASI input or IP input. Simultaneously, the modulator disposes the TS with RS encoding, convolution interlacing and QAM modulating. For the field scope, it can be used for Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.
