Abstract

An encoder (e.g., a Versatile Video Coding (VVC) encoder, etc.) may make real-time encoding decisions to vary a bitrate of a content item (e.g., high-resolution video, streaming content, a movie, a show/program, etc.) by upsampling and/or downsampling portions (e.g., frames/slices, group of pictures (GOP), coding units (CU), coding tree units (CTU), etc.) based on a cost function that utilizes a versatile Lagrangian multiplier (denoted as λto denote the versatility). The versatile Lagrangian multiplier may not only account for the effects of quantization (e.g., a quantization parameter (QP), etc.) on portions of the content item, instead, the versatile Lagrangian multiplier may also be based on adjustment parameters associated with content resolution and/or playback quality of experience (QoE). The versatile Lagrangian multiplier enables a substantial decrease in transmission bitrate for portions of a content item without reducing the visual presentation quality and keeping an end-user quality of experience (QoE) at an optimal level.
