The NAVE II encoder supports VBI encoding in SMPTE 259 video, VANC encoding in both SMPTE 259 and SMPTE 292 and expands upon Nielsen's audio coding technology by increasing the water-marking capability to 12 AES channels or 16 embedded audio channels. Mixed mode embedded and non-embedded (AES) audio configurations are possible, and the unit can be configured to support up to two simultaneous Dolby 5.1 audio streams. A core part of the familiar "SID" data is carried in the audio to allow SID data to survive VBI-stripping by compression systems and new video formats.
The "SID" (Source Identifier) is a second-by-second serial number used by Nielsen and the television industry to uniquely identify program content to ensure proper crediting of viewing.
The NAVE II is specifically designed for standard and high definition digital plants, with embedded or non-embedded (AES) audio. Possible locations include broadcast television stations (digital and analog), broadcast and cable network operation centers, other program uplink facilities, and other distribution sources delivered to television households. This unit is usually installed in the output chain, after all switching and routing.
The optional captioning software module, which supports EIA-608 VBI captioning in 259 and EIA-708 captioning in both 259 and 292 video, provides a very inexpensive way for users to add HD captioning.
