ADTEC Digital EN91P Contribution Encoder

Posted on by

The ADTEC Digital EN91P is an ultra-low delay 1080P MPEG 4 AVC/H.264 high definition encoder.

The ultra-low delay mode requires the use of Adtec’s RD70 IRD and delivers picture-to-picture services in 100 milliseconds; The EN91P standard delay mode is fully interoperable with other IRDs making it ideal for mission critical trunking and ad-hoc applications. MPEG 4 AVC/H.264 is significantly more efficient than JPEG making it the CODEC of choice for multiplexed and bandwidth sensitive applications; AVCs inherent interoperability significantly adds to the value of solutions based on this industry standard.

The lightweight, 10 pound or 4.5 Kilo EN91P offers amazing features and specifications in its 1 RU chassis, including redundant AC power supplies, enhanced control and monitoring via its front-panel, a browser and SNMP; video support includes SD, 2D-HD and 3D AVC 422, sixteen channels of phase aligned audio, robust VBI support, reliability and easy of use all for an extraordinary value. In addition to encoding phase aligned audio, the EN91P pass-through support includes PCM, DolbyE (16 and 20 Bit) and Dolby AC3 (2.0 and 5.1).

The EN91P encodes and concurrently transports services via ASI, IP and DVBS/S2. The DVBS/S2 modulator is available in IF or L-band with modulation modes ranging from QPSK up to 32APSK based on software licenses.

Adtec Digital YUV2QAM Dual Channel High Definition and Standard Definition Encoder

Posted on by
The Adtec YUV2QAM is a dual-channel, high definition and standard definition MPEG 2 broadcast distribution encoder with QAM modulation and RF up-conversion built in.

Its primary application is for use with clear QAM distribution to ATSC televisions. The YUV2QAM automatically detects video and audio, encodes, multiplexes and generates program information (PSIP); it then modulates and up-converts two channels for distribution via coax. Closed captioning and support for Emergency Alert (EAS) are standard. Applications include private cable, hospitality, medical, education and cable television.

YUV2QAM Applications

  • ATSC Distribution
  • DVB Distribution
  • Private Cable
    • Hospitality
    • Medical
    • Education
  • Cable Television MSOs

Benefits

2-Channel High definition encoding: The YUV2QAM automatically detects two channels of video and audio via RCA input, encodes and multiplexes
the signal into a multiple program transport stream with either DVB or ATSC table compliance.

Automatic video detection: Video rates are automatically adjusted based on RCA video input resolution, audio passthrough or encode and QAM
modulation target.

QAM modulation and RF up-conversion: For cable television applications, the unit modulates the signal using QAM Annex A and B and up-converts two video and audio services multiplexed on one carrier frequency for distribution via coax networks.

ASI and GigE output: For non-RF applications, the YUV2QAM delivers ASI (75 Ohm source per EN500083-9) and GigE (MPEG2 or optional RTP multicast transport egress).

Program information: The YUV2QAM is compliant with the ATSC A69 Program and System Information Protocol (PSIP).

Closed captioning and EAS: Support for closed captioning and Emergency Alert (EAS) is standard.

DVB SI: The YUV2QAM is compliant with ETSI EN 300 468 Service Information specification.

Flexible configuration & control: Controlling and configuring the YUV2QAM is easy using the integrated front panel keypad and LCD and web page for
configuration and monitoring.

Ericsson Video Processor Chassis

Posted on by
The Ericsson Video Processor Chassis is a high density, multi-functional, video processing platform. It is designed for the evolving requirements of today’s broadcasters.

The Video Processor has a compact 1RU form factor with up to six hot swappable option slots with a single PSU or up to four option slots with a dual PSU option, making it an ideal solution for the whole spectrum of high resilience to high density requirements. The Video Processor chassis supports a comprehensive range of video processing options, including SD MPEG-2 and HD MPEG-4 AVC encoding on hot swappable option modules.

The platform’s modular design allows service providers to upgrade functionality and add new services incrementally, avoiding costly headend upgrades.

The Video Processor Chassis offers broadcasters the most advanced video and audio compression technology available today and is part of Ericsson’s portfolio of products including receivers, decoders, and descramblers all seamlessly integrated into a complete headend system with nCompass Control by Ericsson.

Video Processor Chassis Overview
Ericsson’s Video Processor Chassis is the basis for the most efficient video compression engines available to the broadcast market.

The platform itself is designed to address both the need for density with up to six option slots and the need for high resilience by making all the option slots hot swappable and the addition of a dual PSU version of the chassis.

Redundancy under nCompass Control by Ericsson can be both card and chassis based for ultimate resilience without disrupting non-failed channels.

The Video Processor Chassis supports Ericsson’s latest range of encoders.

The SD MPEG-2 EN8100 is simply the most efficient SD MPEG-2 encoder available. It delivers high quality SD video at bit-rates previously unachievable with the MPEG-2 standard. The radical design of the EN8100 is aimed specifically at the most demanding low bit-rate applications. The EN8100 is the ideal MPEG-2 real-time encoder for high performance DTH applications via satellite, digital terrestrial or cable.

The EN8190 is Ericsson’s third-generation of MPEG-4 AVC HD encoder. The EN8190 breaks new ground by implementing interpolating RDO coding technology for low bit-rate high quality HD MPEG-4 AVC compression.

Based on Ericsson’s own in house design, the EN8190 pushes encoding efficiency to new levels of excellence beating the previous generation of encoders by up to 25 percent.

Adtec Encoders Send Four Concurrent GIGE Routes per Destination

Posted on by

Adtec’s HD422 Encoders can send Four CONCURRENT (same time) GIGE routes (IP destinations) of the transport stream with unique configuration and FEC (SMPTE 2022) setting per destination! These routes are concurrent with ASI operational and internal constant capture with the hard drive if the TS rate is lower than 40 Mbs (old PATA hard drive limitation).

Adtec HD422 can encode four (4) MPEG 1 Layer 2 {they even support phase alignment of the MPEG 1 Layer 2 audio allowing surround sound without external processors when using the Tandberg TT1290 IRD}. Encoding also supports two (2) Dolby AC3 and two (2) MPEG 1 Layer 2 or any combination up to two each. Example, Encode one (1) Dolby AC3 and encode three (3) MPEG 1 Layer 2 audios.

Adtec can passthrough Dolby AC3/5.1/E, LPCM and Linear Acoustic E2. Passthrough support is via SDI and or AES. We can passthrough up to two (2) compressed Dolby (AC3/5.1/E) or Linear Acoustic E2 or two (2) SMPTE 302M (LPCM) audio streams. Dolby E, E2 and LPCM each take 2.308 Mbs.

Throughput for the 2.308 data rate:
Dolby E supports 4×2 or 5.1+2 (8 channels)
LPCM supports stereo audio (2 channels)
Linear Acoustic Stream Stacker E2 supports two (2) sets 4×2 or 5.1+2 or a total of sixteen (16) channels. E2 is equivalent to two (2) Dolby E boxes.
Base model NTT 9100 can pass one SMPTE 302M (nomenclature they use for Dolby E) and encode 2 MPEG 1 Layer 2. By adding NTTs additional audio board, they can pass two (2) SMPTE302M and even claim to pass four (4) with a very unique method with no audio encode capabilities with either two (2) or four (4) Dolby E passthrough. NTT is limited to TWO PIDs total when in passthrough mode. They claim they can passthrough four (4) Dolby E by combining two Dolby E payloads per AES3. This requires external audio processing to mix two Dolby E payloads onto a 96 Khz AES3 interface and requires sharing a single PID for two (2) Dolby E payloads. NTTs four (4) Dolby E passthrough lacks interoperability and Adtec deems it as very fragile because there is no control or monitoring at the transport layer nor lip sync adjustment per Dolby E stream; they are grouped in pairs of Dolby E. Simply put, they adjust the PID therefor both audios get the same adjustment. I would argue that Adtec and NTT can both passthrough two (2) Dolby E payloads. The Adtec advantage is the ability to pass two (2) and still encode two (2) MPEG 1 Layer 2 audios.
