Metadata¶
The data stream contains additional information about the program: this is called metadata, data about the data. Clicking the Metadata icon allows you to select one or more metadata sets associated with the video stream.
Metadata information may be displayed left or right justified by selecting the left or right arrow adjacent to the Metadata OFF option.

Video and Audio Metadata displays the parameters of how your Volicon MIP is configured to capture and store video and audio content. Parameters include video codec, the pixel resolution, the bits per second, frames per second and audio sampling frequency of each Video Stream.

NAVE (Nielsen Audio Video Encoder) is a Nielsen encoder that adds data to audio and/or video to track the distribution of content through a variety of local and national distribution systems. If the Video Stream you are watching carries a NAVE watermark, choosing this option will display that metadata.

Audio Loudness Metadata displays the audio regulatory environment from which the Video Stream originated: in the capture below, English language from the United States.

AC3 Metadata is the technical name for Dolby Digital Audio Compression. It has been standardized by the Advanced Television Systems Committee (ATSC), and is used for the efficient encoding of surround sound. If your Video Stream is carrying AC3 information to create surround sound, choosing AC3 will display that metadata.

AFD (Active Format Description) is a standard set of codes for television or set-top-box decoders. AFD displays that metadata on your Video Stream. The AFD information instructs the MIP as to what specific format is being sent, either 4:3 or 16:9. Since programs can vary in format in a given stream, the MIP will use the AFD to adjust the format dynamically for display.

DPI or Digital Program Insertion allows cable headends and broadcast affiliates to insert locally-generated commercials and short programs into remotely distributed regional programs before they are delivered to home users. If your Video Stream is displaying locally generated programming, you can see its parameters by observing the DPI metadata.

Input Name Metadata (Analog Only) displays the name of the analog input used to ingest the stream.
