SHAREFLEX™

APPLICATION NOTE ENABLING AND USING SHAREFLEX

2www.grassvalley.com

Understanding ShareFlexShareFlex is the application software, when using K2 Dyno Replay Systems with the K2 Dyno S Replay Controller (K2 Dyno S Replay Systems), to share the content of stand-alone K2 Summit 3G media servers, over a Gigabit Ethernet connection, without the need to trans-fer the content first. This allows a K2 Dyno Replay System with control of local K2 Summit 3G playback channels to cue remote clips, play-lists, and record trains of another K2 Summit 3G without the need to use the remote channels to do so.

In the ShareFlex mode, highlight clips can also be instantly shared be-tween systems. An operator of one replay system can view recorded content, make a clip from a record channel, load and play back a clip, retrieve content from the library, and place a clip in a local playlist. When selected content needs to be transferred, this activity occurs in the background and can be invoked by an action as fast and easy as double clicking on a thumbnail of a clip. Multiple K2 Dyno S Replay Systems can share resources either with the ShareFlex peer-to-peer mode or by using a K2 SAN. Key features of ShareFlex are:

• Sharing highlight clips between systems

• Viewing recorded content locally on a different K2 Summit 3G

• Making a clip from another K2 Summit’s record channel 3G

• Loading and playing back a clip from a different K2 Summit 3G

• Retrieving content from the library of a connected K2 Summit 3G

• Placing a clip in a local playlist from another K2 Summit 3G

ShareFlex allows sharing of record streams from one K2 Summit 3G to others, as if the remote channel is local. Each K2 Summit 3G must have a license to use ShareFlex features. The K2 Dyno S Replay Sys-tem is currently the only way to control ShareFlex features.

K2 Summit 3G can support up to four ShareFlex connections at the same time, one of which is guaranteed to be a real-time connection. The number of real-time connections depends on the number of ac-tive channel streams. ShareFlex connections beyond the real-time limit share the available network bandwidth similar to how FTP trans-fers operate.

Real-time connections act as if they are record channels on the lo-cal K2 Summit 3G. The total number of active channel streams and real-time ShareFlex connections is subject to the supported channel stream limit for the given media type and bitrate.

• Example 1: The number of supported DVCPRO HD (100 Mb/s) channel streams is six. If two channels are recording DVCPRO HD and two channels are playing DVCPRO HD, then up to two real-time ShareFlex connections and two non-real-time ShareFlex connec-tions are allowed.

• Example 2: The number of supported DVCPRO HD (100 Mb/s) channel streams is six. If two ChannelFlex channels are record-ing DVCPRO HD (each channel records two streams for a total of 4 streams) and two channels are playing DVCPRO HD, then one ShareFlex connection is real-time and one other non-real-time ShareFlex connection is allowed.

Network usage on the network interface connector must be below 80% for ShareFlex to operate at these levels. ShareFlex is limited to the maximum disk bandwidth that is supported on the K2 Summit 3G device and limited to the available network bandwidth.

Hardware SetupThe network diagram below shows how to connect two K2 Summit 3G media servers and two K2 Dyno S Replay Controllers together in a standalone configuration. This creates two K2 Dyno S Replay systems.

All connected devices intended to be part of the ShareFlex network require Host Tables with matching IP addresses and computer names for each device.

Make special note that the IP addresses for the K2 Summit 3Gs and the K2 Dyno S Replay Controllers are on the same Subnet, and that the Media connections are on their own Subnet.

The Media connections also require _he0 as part of the computer name in the Host Table description. See the following example.

Same Control Subnet

Same Media Subnet

Computer Name of K2 Summit 3G Server

Computer Name with Media Suffix

Computer Name of K2 Dyno



To find the host table, use Windows Start. In the “Search Programs and Files” field type run and hit enter. When the Run window opens, type drivers and click OK. Open the etc folder. Double click the hosts file and use Notepad to open the file.

Software Setup

The K2 Summit 3G requires v9.1.x or greater and the correct ShareFlex License. Verify with the License Manager (shortcut typically located on the desktop) that the ShareFlex License is valid and current.

Upon the start of a K2 Dyno session, select from the list of available K2 Summit 3Gs to connect to. Here is an example of a location where sharing of a K2 Summit 3G is proposed.



If a session has already been created, and may already be in use, the proposal to turn on sharing is offered again under the Home screen on the K2 Dyno S Replay Controller. Select the Summit List area to open the window that reveals which K2 Summit 3Gs on the network a user can select to both share and look at when it comes to browsing remote content. This list may change as K2 Summit 3G connections join or leave the network.

Using ShareFlex with Live Record Trains1) Select P1 or P2 while Live recording on a local K2 Summit 3G.

2) Use Shift | Browse buttons to list available record sessions.

3) To load the selected angle to a local playout channel, do one of the following:

Select a record train angle from the thumbnails available and touch the LOAD softkey

Double-tap the thumbnail

4) Use the angle buttons to choose from the available streams asso-ciated with the selected record train.

5) Use the Jog Wheel, T-bar, or Play button to control the channel.

6) Press Shift | Local buttons on the K2 Dyno S Replay Controller to return to local record trains.

If P1 is selected to load remote record trains, local record trains and angles are still available under P2. (Verify that connected K2 Summit 3Gs have matching timecode for frame accurate matches.)

Creating Local Clips From Remote Record Trains1) Select P1 or P2 on a local Summit.

2) To list the available record sessions, do one of the following:

• Use Shift | Browse buttons

• Use the Library page to navigate to a shared K2 Summit 3G

3) Select the desired session created by the remote K2 Dyno S Replay Controller.

4) Double-tap the Record Train to load the recording to a player channel.

5) Select an angle to create a clip from.

6) To initiate a transfer of the clip material to the local K2 Summit 3G, mark an In | Out and add to the local Highlight Bin by touching an empty slot or pressing Add HL on the controller.

7) Use Shift | Local to return back to a local record train.

Accessing and Working in a Remote Session1) Select P1 or P2 on a local Summit.

2) Use Shift | Browse buttons to list available record sessions.

3) Load the remote session by tapping the session folder icon cre-ated by the remote K2 Dyno S Replay Controller, and then using the LOAD Session soft key at the bottom of the screen.

4) Select from the Highlight bins to access and play clips or from Play-list bins to access, cue, play, and edit specific playlists.

5) This is considered Help Mode — where two or more operators can collaborate on working with the same clips, playlists, and record trains. When in this mode, creating a clip from the remote record train places it in the remote Highlight bin as well. Also, when adding clips to playlists, they are added to the remote playlists.

6) For future access, add the remote Highlight bins and Playlist bins to your local Favorites Bar.

7) Use Shift | Local to return back to the local session, record train, playlists, and clips.



Using ShareFlex to Cue and Play Remote Playlists1) Use the Library page to navigate to a shared K2 Summit 3G.

2) Select the desired session created by the remote K2 Dyno S Replay Controller.

3) Open the remote Playlist Bin and locate the desired Playlist.

4) Double tap the playlist, or single tap and press Shift | Open buttons on the controller.

5) Press PL button 3 times to cue for playback.

Changing a remotely cued playlist affects the playlist at the local level. When adding remote clips to a local playlist, an FTP transfer must take place first in order for mixing of local and remote clips to take place.

6) For quicker access to remote playlists, add the remote Playlist Bin to the local Favorites Bar.

7) Use Shift | Local to return back to local playlists.

Using ShareFlex to Find Matching Clips on the Network1) Select P1 or P2 on the K2 Dyno S Replay Controller.

2) Select a local Highlight clip in a local Highlight bin.

3) Press Fn | Cue Up buttons on the K2 Dyno S Replay Controller.

4) Select from available matching clips and angles by double-tapping a thumbnail to load the clip on the selected P1 or P2 channel.

5) Use the Jog Wheel, T-bar, or Play button to control the channel.

All angles associated with the clip are available with the angle buttons.

6) Verify that connected K2 Summit 3Gs have matching timecode for frame accurate matches to valid sources across record trains.

The in-point or out-point of the local clip must exist within the range of the guardbands of remote clips to produce valid results.

7) To access clips across the network by way of Library navigation, do the following:

a) Use the Library page to navigate to a shared K2 Summit 3G.

b) Select the desired session created by the remote K2 Dyno S Replay Controller.

c) Open the remote Highlight Bin and locate the desired clip.

8) Use the angle buttons on the controller to select the desired angle for playback.

All angles associated with the clip are available.

9) For a quick access to remote Bins and highlight clips, add the re-mote Highlight Bin to the local Favorites Bar.

Connection Stream Limits1) All K2 Summit 3Gs shipped prior to September 1, 2013 are required

to update the K2 Summit Bios prior to using ShareFlex for the first time to guarantee maximum transfer bandwidth results. (See: “How to Reset Bios” in this document.)

2) Real-time is defined as a stream of highest priority and full band-width.

3) FTP stream is defined as lower priority and non-guaranteed full bandwidth.

4) FTP transfers allow for 4 data transfers to happen simultaneously.

5) Codec variation of bit rates determine the increase or decrease of available real-time and FTP connections. (Example below uses 100 Mb/s as a base calculation.)
