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.

Drake Encoders and Multiplexers
Drake EH24 Encoder Host (6 module capacity)


The scalable Drake Digital EH24 Encoder Host features six bays fitting any combination of SDE24 and HDE24 modules, all within in a 2 rack unit (RU) chassis. The EH24 system can encode up to 12 analog video inputs when fully populated with six SDE24 Encoder Modules. The EH24 can multiplex the encoded video streams and output them via an integrated 1GHz QAM modulator and/or an integrated DVB-ASI port, to transmit the digital video over the network.

The EH24’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 EH24 and installed Encoder Modules are powered by a highly efficient, integrated switching power supply.



SDE24 Standard Definition Encoder Module

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.


HDE24 High Definition Encoder Module

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.

ENC 333A; Encoder HD/SD/1SEG, MPEG2/H.264

The ENC 333A is a high-definition system designed for real-time audio/video encoding for broadcast applications. This device is able to encode several HD and SD formats, providing high quality video, suitable for broadcast transmission. The video encoding technique, H.264 and MPEG-2, guarantees low output bit-rate with a flexible range that goes from 2 up to 25 Mbps. The audio stream is coded with high efficiency and quality, using: MPEG-1 Layer II, AAC-HE and AAC-LC or Dolby Digital Pro.
ENC 333A encodes in SD or HD resolution the video input signal that it come from one of the inputs: SDI, HDMI, and Analog Video (Y, Cb, Cr), according to the coding standards, H.264 and MPEG-2.
The ENC 333A includes not only video processing, but also stereo audio encoding in MPEG-1 Layer II (MP3), AAC HEv1, HEv2 and LC formats, Dolby Digital CE and Dolby Digital Professional. Video and audio elementary streams are multiplexed in an MPEG-2 Transport stream for output over an ASI link. A separate ASI input provides support for an external PSIP/SI data generator. Next to PAT and PMT, PSIP support includes MGT, TVCT and CVCT, while SI support includes NIT, SDT, CAT and TDT.
ENC 326; Two channels multi-standard H.264 encoder tailored for Mobile TV applications

Enc 326, is a 2 channels multi-standard H.264 encoder tailored for the Broadcasting Mobile TV services.
Developed for the next generation of digital video and audio end-equipment applications.
The encoder relies on a powerful hardware platform that features a best-in-class acquisition board, advanced pre-processing filters, statistical encoding, multiple codec support, multi-stream generation, and superior configuration and supervision capabilities. As a result, it is the solution of choice for all mobile TV applications
ENC 334; Four Channel SD-Encoder MPEG2/H.264

ENC 334 is the compact solution for your digital television head end. It provides up to 4 SD channel encoding capacity in order to quickly create a new line up or easily transco- de existing analog channel line ups to new digital ones for either DVB-T, DVB-S, IPTV, cable delivery. ENC 334 provides not only video processing, but also stereo audio enco- ding in MPEG-1, Layer II (MP3) and AAC (HE and LC) formats for each video channel. Video and audio elementary streams are multiplexed in an MPEG-2 Transport Stream for output over an ASI link. A separate ASI input provides support for an external PSIP/ SI table data generator.
