7 results about "Average bitrate" patented technology

A method and device estimate available transmission bandwidth of a network connection used to deliver a data file within a predetermined transmission time. A file size is obtained and a minimum average bitrate required to meet the time is computed as size divided by time. The transmission window is partitioned into alternating first and second time intervals. During each first interval, portions of the file are sent at a bitrate greater than the minimum average. During each second interval, remaining portions are sent at a lower bitrate selected such that the overall average bitrate across the window is at least the minimum average and below a configured bitrate threshold. Feedback (e.g., acknowledgments, loss, delay, or throughput) collected during the higher-rate first intervals is used to estimate the available bandwidth of the connection. The estimate may be used to adjust subsequent interval rates, file scheduling, or admission decisions.

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 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.

A method includes receiving transform coefficients corresponding to a scaled video input signal, the scaled video input signal including a plurality of spatial layers that include a base layer. The method also includes determining a spatial rate factor based on a sample of frames from the scaled video input signal. The spatial rate factor defines a factor for bit rate allocation at each spatial layer of an encoded bit stream formed from the scaled video input signal. The spatial rate factor is represented by a difference between a rate of bits per transform coefficient of the base layer and an average rate of bits per transform coefficient. The method also includes reducing a distortion for the plurality of spatial layers by allocating a bit rate to each spatial layer based on the spatial rate factor and the sample of frames.

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.
