7770DS-HD HD Decompression Codec
1. OVERVIEW
The 7770DS-HD, HDTV Decompression Codec converts a 270Mb/s SDTi (SMPTE 305M) input signal
containing HDCAM compressed data with embedded AES audio, into a SMPTE 292M (1.485Gb/s)
component serial digital stream with embedded or separate AES audio. An additional stereo analog audio
channel is also available for local monitoring. The 7770DS-HD supports 1080i/59.94, 1080i/50,
1080p/29.97sF, 1080p/25sF, 1080p/23.97sF and 1035i/59.94 video formats.
The 7770DS-HD occupies two card slots and is housed in the standard Evertz 3RU frame that holds up to
15 modules.

2. INSTALLATION
The 7770DS-HD comes with a companion rear plate that has eight BNC connectors, occupying two slots
in the 7700FR frame. For information on mounting the rear plate and inserting the module into the frame
see the 7700FR chapter section 3.
Figure 2: 7770DS-HD Rear Panel
2.1. VIDEO CONNECTIONS
Connect a source of SDTi compressed HD serial component video, compatible with the SMPTE 259M and
SMPTE 305M standards, to the BNC labeled SDTi INPUT. See Table 2 for a list of the video formats
supported. Uncompressed HD video output, compatible with the SMPTE 292M standard, is available on
the HD OUTPUT BNCs.
2.2. AUDIO CONNECTIONS
The 7770DS-HD has the ability to de-embed up to 4 uncompressed AES audio streams (8 channels) from
2 groups on the compressed video input. The de-embedded audio can be either re-embedded on the HD
video output or output as AES audio on the 4 BNCs labeled AES OUTPUT. Selection of the audio
destination and embedding group is done by DIP switch (see section 5.6).
A 9 pin D connector labeled ANALOG AUDIO OUT contains 2 balanced analog audio outputs. The
connector pinout is shown in Table 1. See sections 5.5 and 5.9 for more information about the analog
audio outputs.
