Transcoding

The explosion in the number of audio and video codecs used in modern telecommunication networks is making it challenging for network operations. Although some codec standards help carriers by requiring less bandwidth, the need to support numerous codecs increases network complexity and requires greater investment in media processing equipment.

Transcoding converts one type of digital encoding standard to another, achieving interoperability amongst media streams using different codec standards originating from different endpoints in the network.

Transcoding offers network operators the benefit of codec standardization in their networks. By supporting fewer codecs in a network, the carrier can minimize equipment capital expenditures (CapEx) and ongoing operating expenditures (OpEx).

RadiSys Convedia Media Servers support scalable transcoding solutions for next–generation networks

RadiSys is the industry leader in IP media stream processing products and solutions for next generation networks (NGNs), IP-based mobile, and IMS architectures. RadiSys Convedia media servers are deployed globally and support real-time IP audio, video, fax, and speech processing for a large variety of IP-based telecommunication services such as multimedia conferencing, unified communications, ringback tones, Interactive Voice and Video Response (IVVR), or IP Contact Centers. The RadiSys Convedia Media Server product family includes additional features specifically introduced for network transcoding applications and requirements. When combined with our traditional media processing features, plus additional media conditioning functions such as voice quality enhancements, RadiSys offers unique, comprehensive, transcoding solutions for discerning network operators.

RadiSys Convedia Media Server

Highlights of our solutions:

  • Audio transcoding across all supported codecs – including G.711, G.722, G.723.1A, G.726, G.729AB, AMR, and EVRC.
  • Transcoding Process Card (TPC-I) – A new processor blade for Convedia CMS-9000 systems offering a cost-efficient solution for high density transcoding requirements.
  • Standards-based control interfaces: All RadiSys transcoding features are exposed and controlled using open, standards-based interfaces such as SIP with Media Server Markup Language (MSML – RFC 5707). Alternatively, operators may choose to use RFC 4117, a SIP-based transcoding control interface for 2-party calls.
  • Voice Quality Enhancements : RadiSys is the only media server vendor offering a comprehensive VQE feature set delivering VoIP audio quality improvements, advanced VoIP audio processing features, and transcoding capabilities in the same product.
  • Industry-leading densities and scalability: RadiSys Convedia CMS-9000 media servers offer carrier-class densities for core transcoding applications. The combination of scalability, reliability, features, and economics of RadiSys Convedia media servers positions RadiSys as a leading choice for carrier transcoding requirements.
