Metadata¶
The data stream contains additional information about the program; this is called metadata, or data about the data. Clicking the <Metadata information> icon allows you to select metadata sets associated with the video stream. Available metadata will vary depending on the specific channel.

The <Video and audio metadata> option displays the video codec, resolution, bits per second, frames per second and audio sampling frequency of each video stream. The audio status displays the metadata for selected active audio if the program includes multiple audio tracks, such as English and Spanish.
If the CC display is turned on, the “CC” field lists details about CC; otherwise, it is listed as “None”.

XDS displays the source, title and program rating if present in the video stream.

NAVE (Nielsen Audio Video Encoder) watermark will display the metadata of the video stream you are watching if the stream carries a NAVE watermark.

Audio loudness displays the audio regulatory environment from which the video stream originated. If the channel includes multiple audio versions, the active one is displayed.

AC3 Properties 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 Volicon Media Intelligence service 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 Volicon Media Intelligence service will use the AFD to adjust the format dynamically for display.

DPI (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 displays the name of the Volicon Media Intelligence service input used to ingest the stream.
