Original Abstract Submitted
a cloud-based extended reality (xr) system includes a server configured to encode a set of frames each associated with an xr scene to be displayed. to encode the set of frames, the server estimates a total number of encoded output bits for the set of frames based on a set of quantization parameters (qps). the set of qps includes a corresponding qp for each frame of the set of frames and one or more predetermined relationships between the corresponding qps. the server then compares the estimated total number of encoded output bits to a target frame size threshold. based on the estimated total number of encoded bits being outside the target frame size threshold, the server updates the set of qps so as to maintain the predetermined relationships between the qps.
