theibcdaily Friday 13.09.13 119 Early birds boost their muxes In Brief
Conference Analysis By Chris Forrester
An 8am starting time on Day One of IBC’s conference sessions might not be a time when the organisers expect a full room, but ‘Improving Spectral Efficiency’ certainly drew a crowd. Their ‘early bird’ reward was a paper that showed how significant savings could be made in digital transmission. Eric Stare, senior R&D engineer
from Teracom, Sweden, outlined for delegates the potential gains that can be made by maximising

spectral efficiency. Stare compared and contrasted various digital transmission methods available to network planners.
IABM and Devoncroft in market research venture
IABM DC
By Fergal Ringrose The IABM and Devoncroft Partners today announce the launch of IABM DC, a joint venture of the two organisations that will develop and deliver a series of market intelligence products and services for broadcast and digital media clients. IABM DC’s first product will be
the IABM Global Market Valuation and Strategy Report, which will then be published on an annual basis. First created in 2006, this report is the result of a collaborative industry-wide project that provides market-sizing data for the broadcast industry as a whole, and for more than 100 individual product categories.
“The IABM Global Market
Valuation and Strategy Report has been and remains the definitive valuation report for the broadcast and media technology supply market, with detailed regional splits, product and segment analysis, and trends forecasts,” said IABM director general Peter White. “By teaming up with Devoncroft, we gain access to a wealth of valuable new data and expertise that strengthens the report’s modelling and forecasts, and gives us the ability to go on and customise reports for those seeking further forecasting and analysis. Through IABM DC, we will build on the solid foundation that we have created to provide a range of digital media market intelligence going forward.” 8.F50
Teracom showed a variety of
propagation models, including those based on Time Frequency Slicing and Multiple Frequency
Re-Use patterns each of which showed benefits, but by using a combination of these techniques, plus mixed polarisation as well as employing some subtle and highly innovative variations on the cellular-type grid layout, Stare said that potential improvements of up to 50% could be achieved. The panel, chaired by Colonel Dr Natee Sukonrat, vice chairman of Thailand’s National Broadcasting & Telecommunications Commission, also heard papers from Phil Brown, Arqiva’s principal spectrum engineer, and Mark Wadell, the BBC R&D’s lead research engineer.
Doherty tech boosts transmitters NEC
By Michael Burns
A new family of UHF digital TV transmitters from NEC is on show at IBC, taking advantage of power-saving Doherty amplifier technology. The high-power DTU-70D series and the low- to mid-range DTL-30 series transmitters are able to offer an increase in power efficiency of up to 38%. NEC is also showcasing a H.265 encoder, as well as its file-based video servers and super high-resolution techniques. Equipped with a new UX5000QF power amplifier, the DTU-70D enables maximum 17kW operation in a single rack. The unit power of UX5000QF becomes 1.56kW in Doherty mode, taking advantage of the latest generation LDMOS technology. The DTL-30 can also be equipped with new power amplifiers, with customers able to choose the UX400RF for 390W
Concerto interface for Sony’s MBC Software developer Blue Lucy Media (BLM) is releasing a workflow interface to Sony’s Media Backbone Conductor (MBC). Dubbed Concerto, it’s a general-purpose interface between MBC and the Blue Lucy Asset Manager. Sony’s MBC is an enterprise-level workflow automation platform and part of Sony’s tapeless initiative.
The Concerto interface enables BLM components to be ‘slaved’ to the MBC, enabling tape ingest to be assigned from within the MBC environment. It also enables tasks such as bulk tape digitisation utilising Flexicart tape robots that can be posted for autonomous operation. 7.J40, 11.D21
Lively boost for programme prep
A higher power: NEC’s DTU-70D is up to 38% more power efficient
and UX800RF for 780W (both in Doherty mode). The prototype H.265/HEVC encoder can support 4K broadcast (3840x2160 at 60p). It covers several types of input/output signals, offering four HD-SDI Dual Link and four 3G-SDI interfaces. The test encoder also features MPEG-2 AAC-LC and MPEG-4 AAC-LC audio compression. 8.B37
Clearer words for crossing platforms Miranda
By Michael Burns Miranda’s Softel Swift Create V8 caption and subtitle creation workstation is making its European debut at IBC. V8 is a major rebuild of the workstation, including more than 20 new functions that Miranda claimed would vastly simplify the processes required to create, repurpose and manage subtitle files for use on multiple platforms. According to the company,
Swift Create V8 allows captions and subtitles for content delivered to devices such as smartphones and tablets to match the quality of their traditional broadcast channel equivalents. Tools include the Swift Smart File Handling Engine, which supports a wide range of captioning and subtitling file formats and includes extended support for ingesting and captioning unconverted video. Miranda claimed this ‘caption without conversion’ capability meant that users would no longer have to create low-resolution
proxy files to insert and process the required text. A Smart Text import tool saves
review and editing time by using natural language processing to retain original sentence structures. Caption and subtitle repurposing for cross-platform use is also accelerated through integral EDL file support, which automatically generates reversioned captions from edited video by only addressing areas where edits were made. A user-definable Profanity
Guard tool identifies and provides automatic substitutes for
questionable terms, speeding through user-provided lists to ensure inappropriate words are either replaced or permanently deleted. Swift Create V8 also includes a rapid review mode that fast forwards through video portions that do not have captions or subtitles assigned to them, reducing the time required to review or QC the imported files. Automatic alignment checks performed by Swift Create V8 ensure that all captioning parameters will meet pre-defined criteria during the QC process. 8.D41
and archiving Demonstrations of the end-to-end capabilities of Dalet Media Life, which is used for programme preparation and archiving, are taking place on the Dalet stand. Dalet Media Life features the newly revamped Dalet Galaxy interface and MAM platform, as well as a BPM workflow engine that automates many processes. In addition to a complete set of functional tools for mass-ingest, pre-editing, storyboarding, subtitling and captioning, Dalet said Media Life would allow customers to optimise their human and other resources by tailoring QC processes for specific content and channels by using manual ‘sets of eyeballs’ QC or automated QC tools. 8.B77
Totalmovie selects
streaming supplier Totalmovie has chosen a complete multiscreen solution from Harmonic to power its new live TV streaming service. Harmonic said that its advanced adaptive bitrate and
multicast technology enables Totalmovie customers to view 64 high-quality SD and HD channels in more than 40 countries in Latin America and the Caribbean, including Brazil. The premium streaming service has been launched on a range of devices including TVs, set-top boxes and tablets. 1.B20
