- W2069222991 abstract "The very low bitrate requirement for broadband video telephony application is achieved via joint adjustment of frame rate and frame bit allocation. The frame rate control normally modelled using parameters that are related to the residual (error) signal, such as frame difference (FD), displace frame difference (DFD). And motion fields, such as motion vector magnitude (MVM), motion direction activity (MDA) as well as the video frame contrast (VFC) using the original video signal. The computational requirement for this model is very high from the perceptive of constrain on the video telephony equipments. In this paper, proposed a model based on the perceptual quality indicator for bitrate control via frame rate control because the Jerkiness parameter is all about providing the temporal change in the picture and frame bit allocation is predicted based on blockiness, blur and jerkiness. This model is implemented on TI DM642 based broadband video telephones and the experimental results are compared for the encoded video with and without this model." @default.
