EN20 Encoder (2 channel SD & HD)

The EN20 is a two-channel High and Standard definition MPEG 2 distribution encoder supporting ATSC and DVB QAM, ASI and IP distribution platforms.
It inherits Adtec’s broadcast quality compression, advanced feature set, service performance and reliability in the new dense two-channel platform targeted towards broadcasters, cable and IP compression applications.

The device automatically detects video and audio from two sources (combination of HD and SD acceptable), encodes, multiplexes and send them back out as one combined TS via IP, ASI or optional QAM. Closed captioning and support for Emergency Alert (EAS) are standard.
mediaHUB-Pro 02 Encoder (High quality SD & HD)

The mediaHUB-Pro 02 is a real-time Contribution-quality MPEG 2 Standard and High Definition encoder. It is designed to support the most demanding Contribution, ATSC, DVB and IPTV MPEG 2 Distribution applications; the Studio version of the mediaHUB-Pro 02 encodes Cable Labs VOD and DPI compliant MPEG 2 Transport Streams. The Pro’s auto-detect HD/SD-SDI video input eliminates the need for user resolution and frame rate configuration. It boasts dual stream on-board audio encoding of MPEG 1 Layer 2 audio including support for Dolby E and Dolby 5.1 passthrough. Optional dual stream Dolby Digital AC3 encode can be added with a simple software key either at the factory or in the field. Standard Adtec transport interfaces include three ASI copper outputs with included support for transport over GIGE. Audio inputs include AES3 Digital Audio, SDI and Analog audio. BISS 1 and BISS E encryption is an option that can be field activated with a simple software key, no hardware required. The Pro’s user interfaces include a comprehensive easy-to-use front panel interface, on-board Web application server for configuration and monitoring plus SNMP 2.0C MIBS. Unique features of the Studio version include a built-in confidence decoder with HD/SD-SDI, HDMI and D1 outputs.

DTA3050 Multiplexer (10 channel)

Digital television service operators wishing to aggregate and process MPEG, ATSC, Digicypher, or DVB based services for traditional (satellite, cable, terrestrial) services will find the DTA ideal. It boasts 10 ASI inputs. Each supporting wire speed, a three-way mirrored ASI output, GIGE, and optional SMPTE-310. Redundancy for ASI and SMPTE-310 is supported with an intelligent built in relay-bypassed switch. The DTA-3050 is IPTV and BBTV ready today, it supports multicast and unicast configurations including SPTS/UDP, MPTS/UDP, MPEG and DVB tables. Encryption support includes DVB-CSA with Ethernet Simylcrypt, AES for use with Simylcrypt compatible Conditional Access management Servers (CAS) vendors. The DTA 3050 is ideal for traditional and next generation television networks.

Drake DigitalTM EH244 Encoder Host (MPEG2 and MPEG4 H.264 video)

Drake EH24A Encoder Host (6 module capacity)

 

The Drake model EH24A Encoder Host is a platform for supporting modular MPEG2 and MPEG4 H.264 video encoders, including the SDE24, HDE24, and SDI24A. The EH24A multiplexes the encoder outputs into a single Clear QAM RF Channel with up to 12 subprograms, configurable via a front panel interface or remotely over a network by Ethernet web server via an Ethernet port located on the rear of the chassis. The EH24A includes provisions for emergency alert services, using either video replacement or SCTE 18 control messages and is fully compatible with Drake’s “Bandwidth Recovery Solution”.

The EH24A’s sophisticated transport stream multiplexer can combine any or all of the program streams from the Encoder Modules. The operator may select what programs to include in the QAM output channel and, independent of the QAM output, what programs to output via the DVB-ASI port. The QAM RF output can be specified for either off-air or CATV frequency plans in the 54 to 1002 MHz spectrum. The EH24A and installed Encoder Modules are powered by a highly efficient, integrated switching power supply.

 

 

 

 

   

SDE24 & SDE24A Standard Definition Encoder Modules

The SDE24 module can encode up to two input sources, source 1 and source 2 in real-time. The module may be configured to encode source 1 in either MPEG2 or MPEG4 (H.264) transport streams. Source 2 may be encoded in MPEG2 only. Thus each Encoder Module can output one MPEG2 stream, two MPEG2 streams, one MPEG4 stream, or one MPEG2 and one MPEG4 stream.

Each SDE24 module provides two sets of input connectors for NTSC composite with stereo audio. Audio is encoded using Dolby AC-3 encoding.

The SDE24A module can encode up to two input sources, source 1 and source 2 in real-time. The module may be configured to encode both sources 1 & 2 in either MPEG2 or MPEG4 (H.264) transport streams. Thus each Encoder Module can output one MPEG2 stream, two MPEG2 streams, one MPEG4 stream, or two MPEG2 and one MPEG4 stream.

Each SDE24A module provides two sets of input connectors for NTSC composite with stereo audio. Audio is encoded using Dolby AC-3 encoding.

 

HDE24 & HDE24A High Definition Encoder Modules

The Drake HDE24 high-definition encoder module generates an MPEG2 or MPEG4 (H.264) video stream, with Dolby® AC3 or MPEG1 layer 2 audio. This module is designed to be installed into Drake's EH24 or MEQ1000-style chassis which provides the control and output interface to the unit. This configuration of encoder module and host chassis provides the ultimate in bandwidth management and economy by allowing multiple HD and SD streams to be multiplexed together dependent upon the limitations of the bandwidth of the chosen output: QAM and/or ASI.

The HDE24 high-definition encoder accepts non-encrypted HDMI or component video inputs and can inject closed-captioning data from a synchronized composite video source (typically provided by the same decoder that produces the HD video stream). Composite analog audio inputs provide the audio source when component video inputs are used. Typically HDMI has embedded audio but if the HDMI is derived from a source converter that does not provide audio, such as DVI-to-HDMI, then the analog composite inputs may be used.
