Janteq Corporation Overview
1.1 Introduction to the BHDTX-S-TWINTX-HP-AB Transmitter
The BHDTX-S-TWINTX-HP-AB is a high-power digital transmitter using COFDM modulation and MPEG-4
encoding. In addition to the normal DVB-T bandwidths of 6, 7, and 8 MHz, the radio is available with the
narrow band options of 1.25, 2.5, and 5 MHz. The new line of transmitters can cover multiple bands in one
radio and can be ordered in either the L, S, or C models.
The attractive ruggedized base unit is packed with features. The remote control unit has a 2” high resolution
color display provides crisp full frame rate pictures for video confidence and the display of the base unit’s
interactive menus. Local menu navigation is through the remote control unit’s front panel. Four tactile
buttons offer user or administrative-level access.
All Janteq radios use a main profile H.264 codec capable of IBP. This has been further enhanced by adding a
striping technique to create an ultra-low delay option. As a result, the user has a wide range of transmission
options:
• Low delay (≤ 50 mS) offers reasonable quality for reasonable bandwidth. (Optional)
• Normal delay (≈130 mS) offers good quality for reasonable bandwidth.
The base unit features optional full IP connectivity that can provide streaming video at variable bitrates,
along with user data, telemetry, and interfaces to the remote control unit.
