Problems solved by technology

However, since each part needs to be saved in multiple resolutions, this requires a large storage capacity, a solution that is not feasible due to the increased resolution of VR videos
Further, some legacy systems ignore the VR video streaming standard, which prevents streaming across many types of VR video devices (e.g., HMDs)

Embodiment Construction

[0022] One or more embodiments of the present disclosure include an adaptive rate allocation system that provides bandwidth management for high performance virtual reality video streaming. Specifically, in one or more embodiments, the adaptive rate allocation system splits the virtual reality panoramic video into multiple segments, and prioritizes each segment based on the user's current field of view to priority and corresponding rate allocation to stream each segment. In this way, the adaptive rate distribution system improves the streaming of virtual reality panoramic video over that of conventional systems. Further, the adaptive rate distribution system delivers higher quality content to areas in the panoramic video that the user is currently viewing / most likely to view and lower quality content to areas outside the user's view.

[0023] To illustrate, the adaptive rate allocation system accesses or receives virtual reality panorama video (or simply "panoramic video") to ...

Abstract

The present disclosure includes methods and systems for streaming high performance virtual reality video using adaptive rate allocation. In particular, the adaptive rate allocation system divides the panoramic video into segments or tiles and assigns a priority to each tile or segment based on input from the user client device (eg, viewport of the field of view). Further, the adaptive rate allocation system streams each tile or segment to user client devices according to an adaptive rate allocation, which maximizes bandwidth efficiency and video quality. In this way, the adaptive rate distribution system delivers higher quality content to the areas in the panoramic video that the user is currently viewing / most likely to be viewing.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 430,313, filed December 5, 2016, the entire contents of which are incorporated herein by reference. Background technique [0003] Advances in computing hardware and network technology (including the availability of high bandwidth) have enabled the development of networked multimedia applications (online video games, streaming movies, etc.). Recently, there has been a great deal of interest in using three-dimensional (3D) media, such as 3D immersive and virtual reality video applications. Virtual reality video is immersive video mapped into 3D geometry, where the user can look around during playback using a virtual reality head-mounted display (HMD), which gives the viewer a sense of depth in every direction. [0004] Despite recent advances in virtual reality video technology, conventional systems face many challenges in delivering virtual r...
