The engine was specially developed to improve compatibility with client engines such as mobile phones and PCs, in order to achieve seamless applications on network equipment over the network.
Oki’s eSound Engine for Server V2 host media processing software can be used in network terminals to offer value-added service such as IVR, MCU and voice recording equipment.
In general, host media processing software processes media as well as controls communication, such as IP telephony, on a host computer. It facilitates in making applications such as IVR without dedicated hardware.
Based on Oki’s ‘eSound Engine’
, the new host media processing software is available to the global market now. The eSound is Oki’s VoIP technology that enables high quality voice conversation over IP networks. The technology is compliant to various voice signal methods and includes My eSound and eSound Positioning features.
Oki’s My eSound
is a voice band enhancer. It is a function for high-quality communication even when the other party uses a conventional phone, whereas eSound Positioning
is company’s voice service that can include direction to the voice.
Toshinori Suzuki, general manager of telecom system division at Oki, said, “Based on our long years of development of VoIP technology, Oki has been offering a highly realistic communication environment over IP networks with its eSound technology. The ‘eSound Engine’ was announced in April 2006 and has steadily expanded its lineup. The engine is widely accepted in the market and is used in various terminals such as mobile phones and software phones.”
The expansion of IP networks has increased the demand for IP-based host media processing software. As business infrastructures such as thin client and cloud computing are progressing, applications that were enabled on terminals earlier are now enabled on servers on IP-based network infrastructures. This has increased the demand to include commonality and portability in host media processing, says company.
) eSound Engine for Server V2 features common API (application programming interface) for client type eSound Engine such as “eSound Engine ForPC” and “eSound Engine ForMobile.” This helps in reducing application development load, says company.
Oki’s eSound Engine for Server V2 is compatible with multiple codecs. Apart from being compatible with conventional codecs such as G.711, the engine is also compatible with wideband codecs such as G.722. Functionality to mix different codecs is also made available on the engine.
One of the key characteristics of eSound Engine for Server V2 is low delay. Since the engine is equipped with OKI’s original “delay recovery function,” high level of latency recovery can be achieved. The engine is compatible with Windows and Linux platforms, thereby responding to a variety of systems from enterprise systems to carrier systems.
Toshinori Suzuki said, “OKI aims to achieve a 50 percent market share in Japan in the host media processing software market in the fiscal year ending March 2010. We will focus on contributing to telecom carriers’ service expansions in NGN, and will be compatible with various codecs that will be used in high-quality IP telephony services. We will also enhance collaboration with IMS (IP Multimedia Subsystem (News
)) and multimedia middleware technologies and aim to achieve a 30 percent market share in the world market in the next three years.”
