Orban/CRL Releases OPTICODEC-PC Streaming Encoder Version 2.0.

TEMPE, Ariz. -- Orban(R)/CRL (OTCBB: CRLI) has announced the release of OPTICODEC-PC Streaming Encoder Version 2.0. This version features a new mid-cost "SE" standard edition and adds several new features to the already existing PE (professional) and LE (light) editions. All editions of the software let streaming providers supply content encoded with the Coding Technologies(R) AAC/HE AAC/aacPlus codec, widely acknowledged as offering the highest available audio quality at the lowest possible bit rate.

The new SE edition is a Microsoft Windows XP/Server 2003 application that can be used with Orban's Optimod-PC professional signal processing sound card or with any high-quality Windows sound card. Complementing the graphical user interface, a console user interface supports batch file execution to enable easy launching and automation. SE allows up to four encoder instances per stream, supporting up to 128 kbps using the aacPlus codec and up to 320 kbps using the AAC codec. Streaming is possible using both the MPEG-2 and MPEG-4 standards.

In addition to MPEG-2 and MPEG-4 support, the PE edition now supports streaming to 3GPP mobile devices, providing FM radio-quality stereo entertainment from these devices. All editions can supply streams compatible with the standards-based RTSP/RTP free Darwin Streaming Server, which are available for multiple platforms including Linux(R), FreeBSD(R), Sun Solaris(R), Microsoft Windows(R) and Apple Macintosh(R). Also supported are the popular standard HTTP/ICY free Nullsoft SHOUTcast(TM) and Icecast2 servers, which are available for Microsoft Windows(R), Linux(R), FreeBSD(R) and Sun Solaris(R). Robust TCP/IP encoder/server connectivity ensures that even with network interruptions, the encoder will automatically reconnect with the server. The addition of Real Networks Helix Universal Server and Universal Server Mobile (RTP Standards) support allows more AAC/aacPlus encoding options than any other streaming encoder.

An improved user interface in the SE and PE editions offers savable configurations and the ability to launch via GUI, command line, or a batch file. An improved GUI user interface for all editions uses standard Microsoft Windows menu structures for ease of learning and use.

Stations encoded with OPTICODEC-PC can be experienced through RealPlayer(R) 10 or Winamp 5.09 and can be listed on tuner2.com/opticodec.net, a directory service for OPTICODEC-PC streams.
