Page 15

16 SNR Playback Viewer Video Settings Right-click a viewport to access the Video Settings menu. The table below describes the options. Option Deinterlacing Description PAL and NTSC devices stream an interlaced signal. To improve the viewing quality of streaming video on a computer monitor, the signal should be deinterlaced. The optimal deinterlacing method depends on the actual video content. Overscan None Safe area (10%) Overscan set by default for PAL and NTSC has the video image exceed the size of the viewport. This prevents undefined areas from appearing at the edges of the video 20% picture. The overscan percentage, set to Safe area (10%) by default, determines the border area of video that is cropped. 30% Decoding mode Improving video picture quality, video stream latency, and smoothness is subject to trade-offs. Many aspects of picture and stream quality are governed by a number of compression and signal parameters, which may work favourably on one aspect while adversely affecting another. Please consult appropriate literature on MPEG-4/MJPEG/H.264 video streams and applications for a more thorough explanation. Normal Low latency High quality I-Frame Only Default setting. To be selected if you need to keep the time delay between the SNR and SNR Playback Viewer as short as possible. The software does not compensate for irregularities, such as jarring or stuttering effects in the video, caused by erratic transmission delays. Consequently, image quality may vary. To be selected if high image quality is a requirement. Additional buffering space is used to reduce the occurrence of missing frames, giving more latency. To be selected if you wish to reduce CPU load. However, since the frequency with which frames are updated becomes very low, the perceived video quality is negatively affected by I-frame filtering, causing images to flicker or stutter in the viewport. Scaling mode Allows you to select in which scale to display the video stream. Inside Outside Fill Horizontal Fill Vertical Resizes the video to just fill the viewport so that there is no blank border and without hiding any part of the camera scene. Resizes the video to just fill the viewport so that there is no blank border. This may cause part of the camera scene to become invisible. Resizes the video to just fill the viewport in the horizontal direction so that there is no blank border. Resizes the video to just fill the viewport in the vertical direction so that there is no blank border. 1:1 Displays video as specified by the video stream ratio. If the aspect ratio of the viewport is very different from that of the video stream, blank areas will appear around the video. Page 16

17 Working with the Viewports Option Aspect ratio Description Since different cameras may stream differing television standards, the aspect ratio may need to be adjusted so that the images display optimally in a given viewport. Auto Stretch Automatically adapts the aspect ratio of displayed video to match the viewport aspect ratio. The image is stretched to completely fill the width of the viewport. Square Pixel Pixels in a digital video signal are non-square, so that a 100 pixel vertical line may be longer or shorter than a 100 pixel horizontal line, depending on the video standard. Pixel aspect ratio for square pixel is 1/1. A 100 pixel vertical line is as long as a 100 pixel horizontal line. 4:3 Ratio used in conventional displays: 4 units of width for every 3 units of height. 16:9 Ratio used for wide-screen displays: 16 units of width for every 9 units of height.

33 Preserving Recordings for Future Use 6.4 Protecting Recordings In order to preserve them from automatic deletion, recordings can be protected by marking them as Protected. The exact behaviour depends on how the system is configured. Protection of recordings has the following scenarios. A protected video clip will never be deleted from the recorder A protected clip will be deleted after a much longer retention time Protection of recordings has the advantage that the video stays where it is - that is, it is not copied to media which can be lost or misused. Additionally, the normal search and playback operations are available on these clips, which is not the case for exported recordings. On the downside, protected video takes space on the storage system. The use of the protect function must be anticipated and the expected additional storage requirements calculated and built into the system for reliable operation. There are two ways to protect recordings. To protect a video clip in a list of events 1. On the Events tab, select one or more events. Use CTRL+click or SHIFT+click to select multiple events. 2. Right-click the selected event(s), and then select Protect on the context menu. To protect a playing clip 1.
