Average bitrate (ABR) refers to the average amount of data transferred per unit of time, usually measured per second, commonly for digital music or video. An MP3 file, for example, that has an average bit rate of 128 kbit/s transfers, on average, 128,000 bits every second. It can have higher bitrate and lower bitrate parts, and the average bitrate for a certain timeframe is obtained by dividing the number of bits used during the timeframe by the number of seconds in the timeframe. Bitrate is not reliable as a standalone measure of audio/video quality, since more efficient compression methods use lower bitrates to encode material at a similar quality.
AI-adjusted roi encoding for improving license plate text clarity in recorded video
An apparatus including an interface and a processor. The interface can be configured to receive pixel data. The processor can be configured to process the pixel data arranged as a video frame, detect a bounding box location for a vehicle in the video frame, perform license plate detection within the bounding box location to detect a license plate region, determine a first encoding parameter, determine a second encoding parameter for the license plate region, and generate an encoded video frame using the first encoding parameter outside the license plate region and the second encoding parameter within the license plate region. An offset can be applied to the first encoding parameter to determine the second encoding parameter. The second encoding parameter can provide legibility of text while maintaining an average bitrate of the encoded video the same as encoding a full one of the video frames using the first encoding parameter.

Methods and apparatus to determine virtual WIFI data rate
Methods, apparatus, systems and articles of manufacture are disclosed to determine virtual WiFi data rate. An example disclosed herein includes a control frame receiver to capture control frames from a user device. The example disclosed herein further includes a bitrate calculator to calculate a bitrate for each control frame by dividing a bitmap of a control frame by an amount of time between the control frame and a previously captured control frame. The example disclosed herein further includes an interval timer to control a length of time that the control frames are captured before calculating the virtual bandwidth. The example disclosed herein further includes a virtual bandwidth calculator to calculate the virtual bandwidth after the length of time, the virtual bandwidth calculated by dividing an average bitrate from the control frames by the length of time.

An apparatus comprising an interface and a processor. The interface may be configured to receive pixel data. The processor may be configured to process the pixel data arranged as video frames, detect a bounding box location for a vehicle in the video frames, perform license plate detection within the bounding box location to detect a license plate region, determine first encoding parameters, determine second encoding parameters for the license plate region and generate encoded video frames using the first encoding parameters outside of the license plate region and the second encoding parameters within the license plate region. An offset may be applied to the first encoding parameters to determine the second encoding parameters. The second encoding parameters may provide clarity of text while keeping an average bitrate of the encoded video the same as encoding an entire one of the video frames using the first encoding parameters.
