We consider the problem of simultaneous bitrate allocation for multiple video streams. Current methods for multiplexing video streams often rely on identifying the relative complexity of the video streams to improve the combined overall quality. In such methods, not all the videos benefit from the multiplexing process. Typically, the quality of high motion(More)
We consider the problem of bit-rate allocation for multiple video users sharing a common transmission channel. Previously, overall quality of multiple users was improved by exploiting relative video complexity. Users with high-complexity video benefit at the expense of video quality reduction for other users with simpler videos. The quality of all users can(More)
We consider rate allocation for multiple video users sharing a constant bitrate channel. Previously, overall quality of multiple users was improved by exploiting relative complexity. Users with high complexity video benefit at the expense of video quality reduction for other users with simpler videos. The quality of all users can be improved by collectively(More)
Methods for multiplexing video streams often rely on identifying the relative complexity of the video sequences to improve the combined overall quality. In such methods, the quality of high motion videos is improved at the expense of reduction in the quality of low motion videos. In our approach , we use the Edgeworth box solution for competitive(More)
We consider the multiplexing problem of transmitting multiple video source streams from a server over a shared channel. We use dual-frame video coding with high-quality Long-Term Reference (LTR) frames and propose multiplexing methods to reduce the sum of mean squared error for all the video streams. This paper makes several improvements to dual-frame video(More)
In dual-frame video coding, one long-term reference (LTR) and one short-term reference (STR) frames are used for motion estimation and compensation. In previous work, it was shown that the performance of video coding can be improved by pulsing the quality of LTR frames in dual-frame video coding , but this increases the encoder delay buffer size.

I collect data from a modiied ultimatum game designed to enable the estimation of fairness, altruism and learning. In the standard ultimatum game, if the receiver of the ultimatum rejects, both players get zero. In this modiied game, if the receiver rejects, the receiver gets a positive alternative p a y oo, while the sender still gets zero. The receiver's(More)
The infectious enthusiasm of scholars speaking about their research is often perfectly complemented by the never-ending quest of academic audiences for new knowledge, making seminars one of the most forceful and efficient mechanisms for transmitting scholarly information. Indeed, seminar attendance is an integral part of the experience for University of(More)
