Manual

2. INTRODUCTION

Congratulations on purchasing the MLH-300. You now own a high quality, professional DTV headend. To get the

most out of your purchase, please take the time to carefully read through this manual.

3. INSTRUCTIONS

3.1 - DESCRIPTION

The MLH-300 is a very powerful, all-in-one mini headend device, able to receive up to two (2) HD signals and con-

vert them either in two (2) x DVB-T/C RF output channels or in IPTV streaming using UDP/RTP protocols multicast/

unicast.

It supports “pool” technology, meaning that the user is able to select any program from any of the two (2) inputs

and assign them to any of the two (2) RF or IP outputs providing great flexibility.

The embedded web server of the MLH-300 provides a very friendly user interface as well as the ability of remote

or local control of the device via LAN.

Its small size and its powerful features render the MLH-300 the ideal solution in case we want to distribute HD con-

tent eg. coming from STBs or blue ray to a CATV installation using the DVB-T/C or IPTV technology.

3.2.1 - Auto-reset functions and watchdog

During the normal operation of the MLH-300, the main CPU monitors all the internal parts in order to ensure that

the device works normally. In case of an internal error or module failure, the MLH-300 immediately initiates the

recovery procedure by resetting the appropriate module or the device. Finally, watchdog timers ensure that the

device will be reset in case of CPU failure.
