Playout of multiple formats
The K2 client automatically handles material of various types and formats as specified
in the following sections:
Playout on K2 Media Client SDA-00 and SD-00 models
On SD-00 models, for a given frame rate, you can play clips of any format
back-to-back on the same timeline. Refer to the video codec description earlier in this
section for a list of the supported formats.
On SD-00 models, both 16:9 and 4:3 SD aspect ratio formats can be played on the
same timeline. However, there is no aspect ratio conversion mode applied, as there is
on the HD-00 model.
SDA-00, SD-00, and HD-00 models support mixed clips with uncompressed and
compressed (Dolby-E) audio on the same timeline. (requires external Dolby-E
decoder).
Also refer to “VBI/Ancillary/data track specifications” on page 269 .
Playout on K2 Media Client HD-00 models
On HD-00 models, for similar frame rates (25/50 fps or 29.97/59.95 fps), MPEG SD
material transferred or recorded into the K2 Media Client along with its audio is
up-converted when played on a HD output channel. Likewise, HD material is
down-converted along with its audio when played on SD output channel. HD and SD
clips can be played back-to-back on the same timeline, and aspect ratio conversion is
user configurable. Refer to
“Aspect ratio conversions on HD K2 client” on page 262 .
