Video Resolution
The Video Input Resolution fi eld displays the following values:
• 720p50, 720p60, 720p59.94
• 1080i50, 1080i59.94, 1080i60
• NTSC [National Television System Committee]
• PAL [Phase Alternating Line]
Scaling Factor
The Scaling Factor describes the use of magnifi cation in devices to compensate for
differences between size of viewing areas.
Frame Rate
Frame rate, also known as frame frequency and frames per second [FPS], is the
frequency or rate at which NewStream unique consecutive images called frames.
Frame rate is often expressed in frames per second [FPS] and is also expressed in
progressive scan monitors as hertz [Hz].
Profi le
The Profi le fi eld presents the H.264 settings for video, which are also available for
Microwave and Satellite transmission. The Profi le fi eld displays one of the following
values:
• Baseline
• Main
• High
• High 422
GOP
In MPEG encoding, a Group of Pictures [GOP] specifi es the order in which intra-frames
are arranged. The GOP is a group of successive pictures within an MPEG-coded
fi lm and/or video stream. Each MPEG-coded fi lm and/or video stream consists of
successive groups of pictures. The valid range of successive groups of pictures is from
0 to 60.
Low Bitrate
This fi eld displays whether Low Bitrate control is Enabled or Disabled.
Frame Structure
Video frame structure is the division of defi ned lengths of media, such as a sequence of
images in a video, into different fi eld information parts. Video frame structure commonly
defi nes independent key frames, predicted adjacent frames, and bi-directional
frmaes created from the comparison of multiple frames. Key frames contain all of
the information of an image and the predicted and bi-directional frames contain the
difference elements from other frames which results in much lower data that is required
to recreate the images.
