A Trellis Based Temporal Rate Allocation and Virtual Reference Frames for High Efficiency Video Coding
The High Efficiency Video Coding (HEVC) standard has now become the most popular video coding solution for video conferencing, broadcasting, and streaming. However, its compression performance is still a critical issue for adopting a large number of emerging video applications with higher spatial an...
