HALRAUD–D14
Audio Processing Module
Extending the Audio Capabilities of NetVX™
The HALRAUD–D14 audio processing module extends the audio capabilities of NetVX™ by providing up to four additional channels (stereo pairs) of audio I/O. Audio codecs include MPEG-1 Layer 2 and Dolby® AC-3. SMPTE 302 is also provided to support Dolby® E passthrough processing.
The unique cross-connect topology of the NetVX platform provides unprecedented flexibility to route — within a single system — a variety of otherwise disparate sources and destinations. Sources include in-system encoders and remotely originated ASI-, ATM- or IP-based media streams. Destinations include local decoders and transmission paths to remote equipment connected over ASI, ATM, or IP.
Each HALRAUD-D14 audio pair operates in either associated or standalone mode. In associated mode, one or more audio channels are associated with an MPEG-2 encoder or decoder to provide additional audio I/O facilities. In standalone mode, each HALRAUD-D14 channel operates as an independent audio encoder or decoder. For maximum flexibility, the HALRAUD-D14 module’s four interfaces each operate independently from one another. Multiple HALRAUD-D14 modules can operate simultaneously in the same NetVX system.
The integrated encoding, decoding and video networking capabilities of NetVX make it ideal for a wide variety of production, contribution, networking, and video distribution applications.
