520AE4-HD

HD/SD-SDI Audio Embedder

VistaLINK® enabled Dolby Partner

The 520AE4-HD Audio Embedder embeds 4 AES channels into 2 specified groups as defined by SMPTE 299M in a 1.5Gb/s serial HDTV or as defined by SMPTE 272M in a 270Mb/s serial SDTV video signal.

Several optional processing steps can be applied to the input audio before it is embedded. If needed, the 4 stereo AES input channels can be processed by 4 on-board sample rate converters (SRC's). The SRC's can be configured to automatically respect Dolby E & Dolby Digital adding to ease of use & flexibility. The 8 discrete audio channels can be re-arranged in any arbitrary manner with on-board 8 x 8 router. The audio channels may be optionally and independantly delayed up to 3 seconds.

This device also handles the Dolby E Metadata. Metadata is optionally embedded in VANC for downstream devices according to SMPTE 2020.

The 520AE4-HD is housed in the 3RU 500FR exponent frame that will hold up to 16 modules.
