Appendix B Specifications
K2 systems record closed GoP structure. If an open GoP clip is imported, it is fully
supported, including trimming the clip, playout of the clip, using the clip in playlists,
and exporting the clip.
AVC-Intra formats
Playout of multiple formats
The K2 client automatically handles material of various types and formats as specified
in the following sections:
Playout on K2 Summit/Solo
For a given frame rate, you can play SD clips of any format back-to-back on the same
timeline. Both 16:9 and 4:3 SD aspect ratio formats can be played on the same
timeline. Refer to video codec description earlier in this section for a list of the
supported formats.
On channels with the XDP (HD) license, for similar frame rates (25/50 fps or 29.97/
59.95 fps), SD material transferred or recorded into the K2 system 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 an 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 202 .
The K2 Summit Production Client and K2 Solo Media Server supports mixed clips
with uncompressed and compressed (PCM, AC3, and Dolby) audio on the same
timeline.
