Features of SD-00 models
SD-00 models have bi-directional video codecs, which means each of the four
channels support both record and play operations. These models are standard
definition only.
You can encode and decode video using the DVCAM, DVCPRO or MPEG-2
compression standards. You can play clips of any of these compression types through
any play channel without any configuration changes. For example, you can play DV,
DVCPro25, DVCPro50, and MPEG-2 clips back-to-back on the same timeline.
The complete product nomenclature for this model is K2-SD-04, which designates the
channel configuration as four record/play channels. Internal storage and external
storage models are available. Also refer to
“Introducing the SD-00 K2 Media Client”
on page 21 .
Features of HD-00 models
HD-00 models can process either high definition (HD) or standard definition (SD)
video. However, only the MPEG-2 compression standard is used in these HD/SD
models. In addition, these models use dedicated encoders for recording and dedicated
decoders for playing. The number and type (record or play) of channels in the chassis
is determined by the model.
Record channels can record either SD or HD through an HD encoder. Play channels
play both SD and HD clips through an Agile HD decoder. Both HD and SD clips are
played out in the format specified for the output assigned to the channel. All clips are
either up- or down-converted appropriately to play on that output, and their aspect
ratios are adjusted. For example, you can play 50 Hz SD 625, HD 1080i at 25 Hz, and
HD 720p at 50 Hz clips back-to-back on the same timeline.
HD-00 models support encode and decode of SD VBI data and HD Ancillary data,
with appropriate up/down conversion for playout.
The complete product nomenclature for this model designates channel configuration
as follows:
• K2-HD-02 — No record channels, two play channels
• K2-HD-03 — No record channels, three play channels
• K2-HD-04 — No record channels, four play channels
• K2-HD-12 — One record channel, two play channels
• K2-HD-13 — One record channel, two play channels
• K2-HD-22 — Two record channels, two play channels
Internal storage and external storage models are available. Also refer to “Introducing
the HD-00 K2 Media Client” on page 22 .
