Introduction
1.1 Description
The IQEDGE is a 3RU/4RU enclosure containing an IQMIX IP transceiver module and a
customer-defined selection of audio/video processing modules; 3RU models are also
equipped with a cooling fan. Signals are received over IP, converted into SDI, processed, then
converted back to IP for onward transmission.
Fundamental to this is the IQEDGE rear connector panel, which is capable of accommodating
up to four IQ modules. All communication between modules is performed by this unit; as a
bonus, the enclosure’s cabling requirement is also greatly simplified.
1.2 Feature Summary
•
Up to 8 channels per IQEDGE rear panel of common video and audio processing
tasks, in an IP networked environment.
•
Channel branding and side-bar keying facilities.
•
Dolby handling and loudness monitoring to ensure requirements are met.
•
Simulcast format and frame rate conversion processing to provide high quality content
across multiple regions and services.
•
Gain, offset and hue controls.
•
Horizontal and vertical picture enhancement, delay, RGB gamut legalization, aspect
ratio conversion with preset ARC maps, including selectable pan, tilt, aspect, size,
and output crop adjustments.
•
High quality up, down and cross conversion, including conversion aperture control.
•
Noise reduction options (adaptive spatial and recursive), side-bar keying, logo
insertion and frame rate conversion.
•
Processing for 16 channels of embedded audio present on each video channel, with
audio proc features including channel routing (shuffling), gain, invert, delay and
mixing.
•
Advanced audio options, including loudness processing for 4-channel or 5.1 surround
sound, downmixing, upmixing and Dolby E/D encoding and decoding.
•
Aspect ratio control (signalling reading and writing) using ETSI WSS and AFD Video
Index signaling (RP186, SMPTE 2016), closed caption passing or processing for
CEA608/708, and WST/OP42 and OP47 teletext captions, and VITC or SMPTE12M
timecode translation.
•
Built in test pattern and audio tone generators, along with 19-character scrolling
caption generator for signal path testing or keep-alive applications.
•
Full RollCall and SNMP compatibility allows easy integration with SAM or third party
network management systems.
•
Dual 25GbE or 40GbE IP links with multiple transport types available, including:
•
Compressed IP transport using SMPTE-2042 (VC2) low latency high quality
encoding profile;
•
Uncompressed video transport using either RFC 4175 RTP or SMPTE-2022-6
encapsulation;
•
PCM audio using RFC 3190 & AES67;
