The initial selection of a recorded stream is made by clicking on the appropriate ﬁlename

shown in the Listing Directory (also known as the Content Directory; see e in ﬁgure 23

and the About the Content Directory section on page 43 for more information). This

loads all of the content that contains the same preﬁx name and that was recorded at the

same time as the selection. Up to ﬁve channels, each containing different sets of elements,

can be loaded. After the content has been loaded, the user can edit the playback start and

finish times. This is only permitted within the current bounds of the recording time displayed

on channel 1 (also known as video‑player0).

NOTES:

• If any streams in a recording are not required for playback, they can be removed by

unchecking their boxes and clicking Update.

• During replay, the audio, whiteboard, and data streams are always slaved to their

respective video stream. All streams are slaved to the video stream on channel 1.

• The default transport protocols that are used during replay are unicast RTP and

unicast TCP, depending on the selection made at the corresponding decoder device.

If necessary, the multicast RTP transport protocol may also be enabled (see Multicast

Enable on page 40 of the Conﬁg Page section).

The other features of the Player page are detailed below.

a Playback Controls — When a media ﬁle as well as the start and finish times have

been selected, playback can be controlled using the play, pause, and stop buttons

(see the icons below). During active playback, a bookmark can be created using the

bookmark button (see the icons below). Clicking on this button sets a reference point

within the stream that can be retrieved later. A new reference point is placed within the

stream each time the button is pressed and allows for multiple reference points to be

set. For more information on bookmarks, see the Using Bookmarks section on

page 54.

Stop Pause Play Bookmark

NOTE: Attempts to create a bookmark while content is not playing will be ignored.

b netSlave — When multiple player systems are managed by a single controller, it is

possible to synchronize their start and pause operations during playback. This can be

conﬁgured by selecting a suitable netSlave. The netSlave can be set to either Local

NetMaster or to the name of another player in the system.

zWhen Local NetMaster is selected, the local player is either standalone or the

master of a group (if another player in the system selects it as netSlave). Figure 23

shows what a Player page would look like with Local NetMaster selected.

zWhen set to the name of another player, the local player becomes a network slave.

Playback sessions start and pause synchronously, but requires separate play and

pause commands to be issued on each local master player (for example,

a playback channel waiting for a remote system to start or pause will show the

NSYN status).

c auto repeat — Checking this box will result in the current ﬁle restarting immediately

after the ﬁle has ended. Manually stopped ﬁles do not repeat automatically.
