TOKYO--(BUSINESS WIRE)--

OKI (TOKYO:6703) has recently developed Bandwidth Allocation Control Technology to enable OLT*1 drive control for next-generation optical access systems. This technology controls the number of OLT drive units*2 in response to traffic conditions and ensures efficient bandwidth allocation by varying the number of OLT drive units. In addition to dramatically increasing OLT bandwidth efficiency, the technology allows OLTs to sleep when traffic is low, cutting power consumption by a projected 30% on average.

In terms of subscriber access systems (PON systems*3), the rapid introduction of FTTH*4 has been assisted by the spread of GE-PON*5. Based on continuing growth in communications traffic, 10 Gbps PON systems (10G-EPON*6) are currently being developed to expand the bandwidth of FTTH communications. However, higher communication speeds increase power consumption. Projections for higher energy consumption by communication devices have prompted a search for ways to cut power consumption.

To resolve such issues, OKI has worked since 2009 as part of the "Research and development of wide area optical access networks" project commissioned by the National Institute of Information and Communications Technology (NICT). OKI has also sought to develop virtual PONs that would permit flexible configuration of connections between an OLT of central office and user ONUs,*7 thereby ensuring an immediate and practical application of the research technology.

"OKI developed its OLT drive control technology as part of this research program. The Bandwidth Allocation Control Technology developed by OKI is technology that will advance OLT drive control technologies, allowing OLT drive control units to vary the number of operating OLT drive units and thereby responding to bandwidth shortages by adjusting upper bandwidth limits in response to bandwidth volume fluctuations generated by user demand," says Takeshi Kamijoh, General Manager of Research and Development Center at OKI. "Varying the numbers of OLT drive units will result in significantly more efficient use of bandwidth. Verification testing has shown the system can cut bandwidth shortages by roughly one-fifth and power consumption by roughly 30%."

OKI will strive to commercialize this technology, including efforts to extend the technology to multi-channel bandwidth control and deployment to software defined networks (SDN*8).

The research leading to this technology was presented on September 18 at the ECOC 2012 (European Conference and Exhibition on Optical Communication), held from September 16 to 20 in Amsterdam, The Netherlands.

[Glossary] *1 OLT (Optical Line Terminal) A terminal device that forms part of a PON system.

*2 Number of OLT drive units OLT drive control is achieved by switching the OLT MAC (Media Access Control) function on or off. The number of OLT drive units is equal to the number of MAC functions.

*3 PON (Passive Optical Network) system Optical access systems currently in wide use to create networks in which the central office and user devices are connected without active devices.

Last year, ACP magazines reportedly generated earnings before interest, tax, depreciation and amortisation (EBITDA) of about $100 million.

BAUER Media last night signed off on the acquisition of Australia's largest magazine publisher, ACP, after securing approval from the Foreign Investment Review Board.

The move was the last remaining hurdle for the German publisher to take control of popular titles such as The Australian Women's Weekly.

Bauer publisher Yvonne Bauer is expected to arrive in Sydney today, but company executives have been camped out at ACP's Park Street headquarters since last week finalising the details of the deal.

We are pleased to have completed the sale of ACP. Bauer Media is one of the worlds largest magazine groups, and they were a logical owner for the business, said Nine Entertainment CEO David Gyngell.

Mr Gyngell said that there would be close ongoing collaboration between Nine Entertainment and ACP:

Nine and ACP will continue to work extensively together in the years ahead. In Sales, we will maintain focused ongoing cooperation between Nine, ACP and Mi9 through our Powered division. We will also continue to cross-promote ACP and Nine brands across the two companies, he said.

FIRB approval was considered a formality and the sale was effectively sealed last week when lenders to ACP's current owner, Nine Entertainment, gave their approval to the transaction, which will deliver just under $500 million to the debt-laden network owner.

All of the proceeds will be paid to senior lenders who are owed about $2.8 billion and effectively control the network's fate as it needs to restructure this debt if it is to avoid collapse.

Bauer takes control of ACP

NEW YORK (AP) A Citi analyst on Tuesday raised his rating for Liberty Media Corp. to "Buy" from "Neutral," predicting that the company will soon take control of Sirius XM Radio Inc.

Jason Bazinet, who also backed his "Buy" rating for Sirius XM, noted that over the past few months Liberty has spent $1.4 billion to boost its stake in the satellite radio broadcaster to from 40 percent to 49.6 percent. He added that he expects the company to cross the 50 percent line later this year.

Once Liberty Media has a 50 percent stake in Sirius, Bazinet said it's likely that Sirius will begin a $3 billion stock buyback program that will allow Liberty to largely recoup its $1.4 billion investment while keeping a 50 percent stake in Sirius.

Meanwhile, Bazinet expects Sirius' stock should rise to $3 per share over the next 12 months, boosting value for Liberty. In light of that, Bazinet boosted Sirius' price target by 50 cents to $3 and Liberty's by $27 to $121.

The Englewood, Colo.-based conglomerate controlled by cable TV magnate John Malone saved Sirius from near-bankruptcy in 2009 by agreeing to lend it up to $530 million in exchange for preferred stock.

This year, Liberty has been steadily increasing its ownership of Sirius as part of its plans to take control of the company.

In premarket trading, Sirius shares rose 7 cents, or 2.5 percent, to $2.63, while Liberty shares were unchanged at $104.77.

SEATTLE--(BUSINESS WIRE)--

The Open Control Architecture (OCA) Alliance, the industry collective developing a media networking system control standard for professional applications, today announced that it has been officially incorporated as a non-profit trade association.

The incorporation represents the latest milestone for the Alliance, which was founded in June 2011 to develop a standardized control and monitoring architecture for professional media networks.

Since its founding, the Alliance has moved rapidly, releasing initial technical documents to its Observer members in October of 2011, and the complete OCA 1.0 Specification to the Observers in May of 2012.

The Specification now stands at Release 1.1. Coincident with its incorporation, the Alliance has placed the entire Release 1.1 Specification on its public website (www.oca-alliance.com) for free download.

In the coming months, the Alliance will transfer the Specification to a public standards organization for ratification as an official open public standard, free for all to use at no cost. Subsequently, the Alliance will actively support the standards-making process, and will at the same time promote and support the adoption of OCA as a tool for the professional media systems industry.

Incorporation represents another major step forward in the creation of a robust, feature-rich media networking control solution, said Terry Holton, Senior Manager - Product Planning at Yamaha R&D Centre. We are making significant progress, with excellent participation from all our founding member companies.

Bob Tudor, Presonus CTO added, the cooperation between the founding members was critical to the success of OCA 1.0. We are achieving cross-brand control of parameters in our devices as a result, which is good for our respective customers and a stimulus for market growth.

Nathan ONeill, LOUDs VP Engineering, notes a key aspect of the OCA specification has been to allow for common control functionality yet provide manufacturers the ability to customize the protocol to their own needs, much like MIDI Sysex messages in this way they get the best of both worlds the ability to control functions across a multi-manufacturer system, yet the ability to keep manufacturer-specific algorithms proprietary.

With the OCA Alliance moving forward, integration of an audio system with a media control system will definitely get a lot simpler, commented Marc Weber, Product Manager, d&b audiotechnik. This means that the integrator can concentrate on the interface to the user rather than on the actual programming itself.
