Stereo Sound/SAP
The DView supports Multichannel Television Sound (MTS), the broadcast audio standard that
allows transmission of both stereo and Secondary Audio Program (SAP) content.
The SAP is usually a foreign-language translation. However, it can also be used for other
purposes such as Described Video Services (DVS), which provide descriptive narration of key
visual elements in programs for the benefit of the visually impaired.
You can select sound options (Mono, Stereo, SAP or
Mono+SAP) depending on the broadcast signal by
pressing the MTS/SAP button on the remote control.
• Choose Stereo for channels that are broadcasting in
stereo.
• Choose Mono for channels that are broadcasting in
mono, or if you are having difficulty receiving a
stereo signal.
• Choose SAP to listen to the Secondary Audio
Program.
• Choose Mono+SAP to listen to both the primary and
secondary audio programs (for example, when a
program has a DVS audio track).
Table 4-4 summarizes the audio broadcast modes supported by the DView.
