ENR-1000 Series System Administrator’s Manual

Video Display Performance

On a live or playback screen, ENR handles displayed video based on the combination of the

following factors, which you should put into consideration when configuring your view layout:

(1) The number of channels of your current layout

(2) The format of video stream, e.g. resolution and frame rate.

To balance the loading of the system, ENR will decode only I frames (*1) for live view when

CPU usage is critical. The video stream is still recorded at its original frame rate regardless

of the display quality.

To acquire good video display quality, however, it is suggested that you try to use the layout

containing just enough channels, or make use of Sequence Patrol function.

Local Live View / Playback

On local display, ENR determines when to enter Decode-I mode according to these key

references – (1) your selection of Layout and (2) the Video Resolution. A layout consisting

of more channels and high-resolution streams are considered more CPU consuming, which

is more likely to trigger Decode-I mode. Take ENR-1100 for example, by switching the live

screen layout from 4x4 style (16 channels) to Quad style (4 channels), the video quality will

appear much smoother.

On a local live or playback screen, try to meet the conditions below for ideal video display

quality(12~30 FPS); otherwise, ENR will decode only I-frames for each channel.

(*1) A video sequence is composed of a series of GOP (Group of Pictures). Among these

pictures, I-frame (Intra-coded picture) is a fully specified picture with complete image

information, while P-frame and B-frame hold only partial image information.

(*2) ENR-1200 and ENR-2000 will automatically turn all channels into Decode-I Mode

when the number of layout channels exceeds 8.
