Abstract:
1. A computer-readable medium having embodied thereon a program, the program being executable by a machine to perform a method for adjusting a video bit rate (VBR) during transmission of video data over a packet-switched network, the method comprising: reducing the VBR to no less than a minimum video bit rate threshold (VBRmin), if a packet loss (PL) over a time interval is greater than a PL threshold; increasing the reduced VBR by a bit rate enhancement factor (BREF) to obtain a second VBR, if the PL over a maximum integer number of time intervals (ntMax) is less than or equal to the PL threshold; increasing the ntMax if the PL at the second VBR is greater than the PL threshold; and increasing the second VBR by the BREF for each consecutive time interval until a VBRmax is reached, if the PL for each previous time interval is less than or equal to the PL threshold.
