K2 Media Client features
This section provides an overview of K2 Media Client features. Refer to Appendix A,
Specifications for details.
The following features are common to all models:
• Four channels (maximum) per chassis
• SDI video inputs and outputs
• AES/EBU or embedded audio inputs and outputs.
• Redundant power supply, RAID 1 protected Windows XP system disk, cooling
fans for reliability
• RAID media storage
• Remote operation and configuration via AppCenter
• NetCentral™ provides remote error reporting and monitoring via SNMP (Optional
for models using internal storage only)
• Gigabit Ethernet
• AMP, VDCP, and BVW remote control protocols supported

• GPI Trigger (12 I/O)
• Support for import of various media and graphics file formats, with transcode as
necessary to native file format.
Features of Standard Definition models
Standard definition (SD) models are SD-only, in that they neither encode nor decode
high-definition video. SD-only models have bi-directional video codecs, which
means each of the four channels can be configured to be either a record or a play
channel. 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.
SD-only models support encode and decode of VBI data.
Features of High Definition models
High definition (HD) models are really HD/SD, in that they can process either SD or
HD 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
