Clickview Video Resolutions, Codecs, And Quality

720 refers to the number of lines from top to bottom

Digital television broadcasts use the aspect ratio of 16:9. This aspect ratio, also known as widescreen or HDTV, is wider than the traditional 4:3 aspect ratio used in older analog television broadcasts. The 16:9 aspect ratio provides a wider field of view, allowing for a more immersive viewing experience and better compatibility with modern widescreen displays. It has become the standard for high-definition television (HDTV) broadcasts and is commonly used in digital media formats such as DVDs and streaming services.

The explanation for the given answer is that ClickView Library Server prefers to use the WMV video container format with video compressed using the VC-1 codec. On the other hand, ClickView Online prefers to use the MP4 video container format with video compressed using the H.264 codec. Therefore, the statement is true as it accurately reflects the preferred video container and codec for each platform.

When a 480p video stored within ClickView Library Server is synchronized to ClickView Online, the video resolutions that will be stored on ClickView Online are 240p and 480p. This means that the video will be available in both 240p and 480p resolutions for streaming on ClickView Online.

Aspect Ratio

The correct answer is H.264. This is the correct way to reference the codec. The "H" represents the ITU-T H. series, which includes video coding standards. The "264" refers to the specific standard within the H. series, which is used for video compression. The capitalization of the "H" and the use of a dot between the "H" and "264" are important for accurately referencing the codec.

The answer is false because the video in the ClickView Library Server is in WMV format with a bitrate of 1Mbps, while the video in ClickView Online is in MP4 format with a higher bitrate of 2Mbps. Therefore, the video in ClickView Online will have a higher quality and bitrate compared to the video in the ClickView Library Server.

The correct answer is 2Mbps. This means that when a 720p video is recorded by ClickView 24-7 Cloud and available from Workspace, it will have a bitrate of 2Mbps. Bitrate refers to the amount of data that is processed per unit of time, so a higher bitrate generally results in better video quality.

'p' stands for 'progressive scan'

Only the highest ClickView Online resolution is stored in the local cache

The SD (standard definition) video recorded by ClickView 24-7 Cloud is recorded at 240p resolution. The bitrate refers to the amount of data that is transmitted per second in the video stream. The given correct answer of 400Kbps suggests that the video has a bitrate of 400 kilobits per second. This means that the video is encoded and compressed in such a way that it requires a data transfer rate of 400Kbps to be played smoothly.

When a 1080p video stored within ClickView Library Server is synchronized to ClickView Online, the video resolutions that will be stored on ClickView Online are 240p and 720p. This means that the video will be available in both 240p and 720p resolutions for streaming on ClickView Online.
