BROADCAST FEATURE Monitoring and Measuring

A host of new monitoring options are going to be prevalent at IBC this year thanks in no small part to IP networking developments, file-based programme delivery requirements and the continuing quest for loudness control. Wohler (10.B10) will have its flagship AMP2-E16V modular audio and video processing monitor on show. Features include simultaneous multi-format monitoring, quick program selection, instant stereo downmix, loudness monitoring, internal channel mixing (including SDI re-embedding), and audio delays. With networked facilities and

broadcast operations in mind, a new AVB Monitoring Option card will also be on show that allows AVB (Audio-Video Bridging) channels to be mixed, level-adjusted, and monitored alongside AES, SDI, analogue, and other input types, and in the same fashion. A set of MPEG DVB-ASI and

IPTV monitors will make their debut at IBC too. Tese decode and then provide at-a-glance monitoring of programme content from MPEG-2/4 ASI and Ethernet IP streams, as well as 3G/HD-SDI inputs. With the continued clamour for

remote working, a software-based monitoring platform called iON may also be worth a look. Tis innovation gives users the ability to access, control, and manage a broad range of signals and associated data remotely from any web-enabled computer, mobile or tablet, with video and audio content streamed in real time. TSL Products (10.B41) will present

several European product launches that address the increasing demand for workflows based on audio and/or video-over-IP. Te PAM AVB range – for monitoring connections based on Audio-Video Bridging as well as SDI, AES, and analogue audio formats – and the AXIUS range of managed Ethernet switches will both be on show. As will the PAM PiCo Touch audio, loudness, and logging meter. “As the adoption of audio and video-over-IP continues to grow apace, we are excited to bring products to market that will help our customers to make the transition with tools that they know they can trust,” says managing director Chris Exelby. Of course it is difficult to go to IBC these days without getting involved in at least one discussion about loudness

20 August/September 2014 New from Nugen is DPP AS-11 programme compatibility for LMB

(even if it’s just bemoaning the racket being made by the stand demos in Halls 7 and 8). Nugen Audio (8.A76) is billing itself as the “go-to company for loudness management and compliance”, according to founder and creative director Jon Schorah. And it’s being done with at least one eye on October, the month in which television programme delivery in the UK will move from tape to file-based, as set by the DPP (Digital Production Partnership). New from Nugen for 2014 is DPP AS-11 programme compatibility for LMB, the offline file-based loudness analysis and correction technology. A native MXF file-handling option now enables LMB to perform automated analysis and correction of audio within an MXF container while preserving all other data within the file. Nugen will also showcase version 1.1 of MultiMonitor, the company’s loudness and true-peak monitoring software application. Te new version includes network meter reset options and a “tall” meter configuration. On that same theme, DK-

Technologies (8.E60) is offering an upgrade for its DK T7 audio, loudness and logging meter that includes loudness automation. Available free-of-charge to both existing and future DK T7 users, it is based on SMPTE timecode and allows the DK T7 to instantly recalculate the integrated loudness value up to a four-hour period. Audio engineers could save lots of time with this as it means they no longer have to re-run programme material to hit their loudness target value.

Intercom and Talkback

Intercom and talkback is big business as the wireless and IP evolution continues. At IBC2014 Riedel (10.A31) will

introduce Tango, what it describes as “an entirely new intercom solution”. As Audio Media went to press, details were still being finalised, but expect a big splash at the show. Something we do have details of is a completely redesigned virtual control panel from Trilogy (10.A29). Now available for PCs, laptops, phones, and tablets in either wired or wireless configurations, it allows more people than ever to be part of a comms network or, as the company puts it, ‘join the conversation’. IBC will also be the venue for a demo of L-S-B’s Virtual Studio Manager working in conjunction with Gemini, Trilogy’s distributed matrix intercom. Tis has come about thanks to the implementation of the Ember+ protocol. Te lower-end Messenger matrix-based intercom will also be on show.

Clear-Com (10.D29) will have a

new version of its 1.9GHz roaming digital wireless intercom system FreeSpeak at IBC. Version 2 is an “enhanced DECT-based offering that operates in multiple licence-free DECT bands from 1.897-1.933GHz”. Available as an integrated or standalone technology, FreeSpeak II allows more people, using wireless beltpacks, to roam across a production area at the same time. When using the base station, 20 full-duplex wireless beltpacks can be connected while, in a matrix setup, connection to 50 full-duplex wireless

beltpacks is possible by placing 10 or more distributed remote antennas together to create an expansive coverage zone. Clear-Com director of product management Simon Browne says: “Te introduction of the redesigned FreeSpeak II Beltpack and Antenna provides rugged and ergonomic operation, together with greatly improved radio and audio clarity.”

Networking, Routing, and Convertors

When it comes to linking things together, the Riedel stand is a good starting point. “We are continuing to develop next-generation solutions that leverage the power and convenience of our networked approach to signal transport and routing, and look forward to launching a few of these at IBC,” says chief executive Tomas Riedel.

MediorNet 2.0 will be one focus. Tis is a firmware update for the real- time signal routing and distribution network that provides video router functionality, high-speed re-routing and WAN capabilities. Supporting FEC (Forward

Error Correction), retransmission management and dynamic bit rate management, the Code One Transport Protocol used by MediorNet H.264 encoders and decoders ensures that the public internet can be used for point-to-point transmission of audio and video.

Riedel will also show MediorNet

MetroN, a 2RU large-scale core router that provides a real-time routing capacity of 64 x 10G ports. MediorNet
