Digital Headend Products

The Blonder Tongue Digital Collection offers a comprehensive series of products designed to multiplex, modulate, demodulate, process, and transcode signals in ASI, QAM, 8VSB, QPSK, and 8PSK formats.

Hi Constanza

The Blonder Tongue HDMI to QAM Encoder accepts one input in HDMI format such as a locally owned/originated content. It delivers one HD MPEG-2 encoded output in QAM format in the 54-864 MHz range, suitable for the distribution over a typical private coaxial network like sports arenas, broadcast and cable-television studios, airports, hospitals, university campuses, etc.

The Blonder Tongue SD10E-QAM accepts & auto-detects up to ten (10) inputs in SD (480i) and NTSC baseband Audio/Video formats. The encoder, when applicable, digitizes, & MPEG-2 encodes each into a standard-definition stream (SD-480i), and then multiplexes the resulting ten (10) streams into one (1) output in QAM format in the 5.75-864 MHz range (CATV channels T7-T14  and 2-135).

The Blonder Tongue HDMI to QAM Encoder auto-detects input streams in HD, SD, and analog NTSC formats, and delivers one HD/SD MPEG-2 encoded output in ASI format.

The Blonder Tongue HDE-2H-QAM accepts & auto-detects up to two (2) input streams in unencrypted HDMI & Component formats. The encoder, when applicable, digitizes & MPEG-2 encodes each input into a high-definition stream (HD-1080i/720p), and then multiplexes the resulting two streams into one output in QAM format in the 54-864 MHz range (CATV channels T7-T14 and 2-135). Any combination of input multiplexing is allowed.

DHDC-UV - Digital and HDTV Upconverter Module

DHDC - DV - Digital and HDTV Downconverter Module

The Blonder Tongue QT Transcoder accepts one input in QPSK or 8PSK format, and delivers one output in QAM format in the 54-864 MHz range.
The four available models are:
1. QTM-II accepts one input in QPSK format, and delivers one output in QAM 64 mode.
2. QTM-HD accepts one input in QPSK or 8PSKformat, and delivers one output in QAM 256 mode.
3. QTM-HD PLUS is the same as QTM-HD, but capable of QAM 512/1024 modes.
4. QTM-HD NPU is the same as QTM-HD, but with a “Null Packet” feature that allows adding/removing null packets to/from the input stream.

Both DAP and DAP-PLUS can be equipped with an optional RNC module (Remote Network Card) that allows remote monitoring and configuration of the unit.

Modulators

The Blonder Tongue AQM accepts one MPEG-2 digital transport stream encapsulated in an ASI format, and delivers one output in QAM format in the 5.75-864 MHz range.

Edge/IP Solutions

The Blonder Tongue EQAM400 accepts HD content through its GbE input interface, and delivers up to eight (8) outputs in QAM format, protected with Pro:Idiom™ encryption, in the 54-864 MHz range. The EQAM-400 can be configured with four output modules, each capable of delivering two (2) adjacent QAM outputs. Each QAM channel can contain two HD programs encoded in MPEG-4 or MPEG-2 for a total of 16 HD programs per EQAM- 00. The EQAM-400 is designed to accept up to 1 GbE of input from several sources; to transcode program streams into QAM; and to add Pro:Idiom™ encryption to each program stream.

The Blonder Tongue AQD PLUS is the same as AQD but with AFD (Active Format Description) feature.

Two types of input modules are available (ASI and 8VSB/QAM), and any combination of input modules is allowed - for example DQMx can be equipped with 2 ASI and 2 8VSB/QAM input modules.

The Blonder Tongue MUX-2D-QAM Multiplexer is designed to allow CATV operators to multiplex two digital channels received in either 8VSB or QAM format to a single QAM output channel for delivery over a standard coaxial distribution network.

It accepts up to two (2) 8VSB or clear QAM channels and aggregates them onto one QAM RF output in the 54-864 MHz range. The MUX-2D-QAM provides the capability to filter program streams and to assign major/minor or a single 4-digit channel number to each.

The Blonder Tongue MUX-12A-IP Multiplexer is designed for cherry-picking applications, allowing operators to create custom-made channel lineups by grooming standard and high-definition (SD/HD) programs on an as-needed basis.
