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)
OVERVIEW In June of 2000, forty-four scientists gathered in Tempe, Arizona to discuss the needs and priorities for interdisciplinary environmental research, spanning natural sciences, social sciences, engineering, and humanities. Attendees came from over a dozen different fields, and represented thirty-one institutions. This report presents the consensus(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)
Businesses and governments devote substantial resources to the collection and analysis of survey data concerning the public's preferences. The possibility of strategic responses to such surveys is analyzed. Consequential and hypothetical surveys are formally defined. For the former the question is posed: what form should strategic behavior take? The(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)
