Features of internal storage models
The K2 Summit Production Client and K2 Solo Media Server have bi-directional
video codecs, which means each channel supports both record and play operations.
You can encode and decode video using the DVCPRO HD, DVCPRO 25/50, or
DVcompression standards. You can also decode MPEG-2. Options include MPEG-2
encode and AVC-Intra encode/decode. All channels support Standard Definition
(SD) video and, if licensed, each pair of channels can also support High Definition
(HD) video. For more information on available codecs, see
You can play a sequence of clips of different compression standards and, if licensed,
HD and SD formats back-to-back on the same timeline with no channel configuration
changes. 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 the K2 Summit Production Client, stand-alone internal storage, stand-alone
external direct-connect storage, and external shared (SAN) storage models are
available.
Features of internal storage models
An internal storage K2 Summit Production Client can have eight media drives. A K2
Solo Media Server has two media drives. Compact Flash serves as the system drive.
This makes the internal storage K2 system a self-contained, stand-alone unit, with no
external devices for storage connections required. You can transfer media in and out
of the internal storage K2 system via Gigabit Ethernet. You can also export media to
a mapped drive or USB-attached storage. With the K2 Solo Media Server, you can
also export media via the ExpressCard.
Features of external storage models
The external storage K2 Summit Production Client contains only the Compact Flash
that serves as the system drive. There are no media drives in an external storage K2
Summit Production Client. There are two types of external storage for media, as
follows:
• Shared storage — Multiple external storage K2 Summit Production Clients
connect to the K2 SAN via Gigabit Ethernet or Fibre Channel to share a common
pool of storage.
• Direct-connect storage — A single K2 Summit Production Client with the optional
Fibre Channel board installed connects directly to its own external (non-shared)
RAID storage device. This makes the direct-connect K2 Summit Production Client
a self-contained, stand-alone unit, with no external (non-shared) devices for
storage, audio, or video connections required. You can transfer media in and out of
the direct-connect K2 Summit Production Client via Gigabit Ethernet.
