JVC TDR6 installation and operation guide Overview

Page 12

The TDR6 supports both single-channel-per-carrier (SCPC) and multi-channel-per-carrier (MCPC) operations and can be deployed in either a point-to-point or point-to-multipoint system.

If the TDR6 has been configured to receive satellite transmissions, it will accept input from 950 to 2150 MHz at power levels between -65 dBm and -25 dBm. It can also interface directly with satellite low noise block (LNB) downconverter input at up to 30 Msps, -25 dBm to -65 dBm. The TDR6 will receive a DVB or ATSC-compliant input signal, demodulate and decode the signal, and deliver separate video, audio, and optional data (for example auxiliary data or teletext) signals.

If the TDR6 has been configured to receive a terrestrial transmission, it will accept a signal compliant with the acceptable formats described in the option module section, decode the signal, and deliver separate video, audio, and optional data signals.

Option Modules The TDR6 has a modular construction which allows for easy expansion. The TDR6 accepts up to six option modules and can be rapidly altered to suit your needs.

Video Processing The TDR6 can be configured to support SDTV in NTSC and PAL formats. Video output provides both analog composite and digital D1 MPEG-2 4:4:2 or 4:2:0 formats, which are automatically sensed by the decoder.

The TDR6 can also be configured to support decoding of HDTV signals in either 1080i or 720p formats through the use of an option module. HD Video output provides 1.5 Gbps SDI.

Audio Processing The TDR6 provides decoding of up to two stereo or four mono channels of program audio in standard definition configuration.

A total of four additional stereo (or eight mono) channels of MPEG audio may be decoded using one additional option slot. Audio output is digital AES/EBU. Up to four AC3 audio channels are supported using external AC3 decoders.

Auxiliary Data Delivery The TDR6 is able to decode and deliver uncompressed optional data streams. This data may take the form of non-specific auxiliary data, or, depending on the transmission site, may be data such as teletext or other video or audio specific data. The installed option modules define the data types the TDR6 can decode and deliver to the receive site.

In its basic configuration the TDR6 supports two channels of synchronous data up to 2048 kbps or asynchronous data up to 34.8 kbps on EIA-232 and EIA-422 ports.

Input Interfaces The TDR6 can be configured for various inputs through the selection of input option modules. For example, a TDEM-6110 QPSK/8PSK/16QAM demodulator module allows the TDR6 to perform as an SDTV or HDTV IRD with four switchable L-band inputs.

Auto-Sensing Decoding The TDR6 features auto-sensing of the audio and video formats. Once the unit is locked onto an incoming signal and a service is selected, the TDR6 automatically configures parameters based on the information detected in the selected service.

Monitor and Control Functions The TDR6 monitor and control functions include:

■Front panel operator control utilizing an easy-to-use, intuitive menu and push-buttons

■Remote control using either an Ethernet or RS-232 interface
