The progress indicator in Day view displays playback progress for one hour of video. Major

graduation marks denote 5-minute intervals, and are labeled accordingly. Minor graduation

marks representing 1-minute intervals are present between the major graduation marks.

Multiple video segments may exist within the selected hour. Video segments are indicated by

alternating light green and dark green bars below the progress indicator. Each alternating bar

represents a single video segment from the play list. Time spans, for which there are no

associated video segments in the play list and no available video, are gray.

Direct Indexing

Direct Indexing is the ability to start playback at a specific time within an available video

segment by dragging the progress bar slider to a point on the progress bar corresponding to the

desired time.

The Direct Indexing mode functions differently depending on the video source (server) selected

for the current session. There are two categories of video sources that can be accessed using the

BUS-WATCH® Play back application: Local and Remote Playback sources. For more

information on video source selection types, please see the section titled Source Selection on

page 28.

For local playback sources, or video sources that are stored on the host PC or on a USB

connected R1001/R4001 Hard Drive Module, any time within an available video segment in the

selected hour can be directly indexed.

To directly index video from a local playback source, start playback at the current playback

location and drag the slider bar to the desired time within an available video segment. Playback

will jump to the selected location and continue.

For remote playback sources, such as a BUS-WATCH® Mobile DVR connected to the host PC

through a network connection, video must be buffered before direct indexing can be used.

Buffering is the process of reading and storing video from the selected video segment in the

memory of the host PC in advance of playback, indexing, or other operations. Upon selection of

a video segment within the play list, the BUS-WATCH® Play back application begins buffering

the selected file in anticipation of playback or other operations.

During playback, the BUS-WATCH® Play back application reads and buffers video from the

currently selected video segment at a rate slightly higher than required for playback to assure

uninterrupted playback. When playback is paused or in a similar mode, buffering continues until

the entire current video segment is buffered.

Buffered video from the current segment is indicated by a light green bar filling in the area

behind the progress bar slider. Buffering occurs in both File and Day progress bar modes.
