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.

A companion Norpak unit, the Nielsen Universal Reader, will decode and display the SID data to allow users to verify the encoded information.

Interface Connections

Video: Digital SD and HD video per SMPTE 259M and SMPTE 292M Serial Digital Interconnect (SDl)

Audio: Six pairs of 75-ohm BNC jacks, providing IN and OUT connections for six AES pairs. Input and output signals are unbalanced, 1V nominal into 75 ohms, and comply with SMPTE 276M. 24 bit resolution at 48K sample rate audio is maintained.

One DARS (AES11-1997) input for optional audio synchronization.

Audio and video terminations are 75 Ohm single ended.

Three serial ports (control, time code, captioning input).

RJ11 and RJ45 Ports for modem and LAN (software updates and configuration).

Contact closure for remote bypass.

Audio/Video Synchronization

Audio and Video are delayed by one frame maintaining proper lip-sync timing. (2 frames for 720p).
