| Abstract: | We address the problem of real-time encoding multiview video for interactive multiview live video streaming, where clients can interactively switch views during video playback. In other words, as a client is playing back successive frames (in time), it sends requests to the server to switch to different views while continuing uninterrupted temporal playback. Noting that standard tools for random access (i.e., I-frame insertion) can be bandwidth-inefficient for view switching, we propose an algorithm to select and encode an optimal combination of I- and/or redundant P-frames in order to facilitate view switching for a given computation constraint. We show in our experiments that we can generate redundant frame structures offering a range of useful tradeoff points between transmission and computation, including ones that outperform simple I-frame insertion structures by up to 32.9% in terms of bandwidth efficiency, if we are willing to double computational resources devoted to encoding. |
