Wireless Transmission Using First and Second Radiation Beam Patterns

A video stream is wirelessly transmitted robustly and uses minimum energy. A base stream and at least one enhancement stream is obtained representing the video stream, the enhancement stream(s) including additional information that, when combined with the base stream, enhances the video stream rendering. First and second radiation beam patterns of an antenna are determined such that radiated signals resulting from the first radiation beam pattern (e.g. omni-directional or wide beam pattern) have greater or equal spatial robustness than radiated signals resulting from the second radiation beam pattern (e.g. narrow beam pattern). The base and enhancement streams are transmitted through the antenna using, respectively, the first and the second radiation beam patterns. Feedback from the receiving device may indicate that transmission quality is above or below a threshold. Such an indication may control transmission path direction. The base stream may be obtained by sub-sampling the video stream ...
