Abstract: A method of transmitting video data related to a sequence of video frames, includes: encoding the video frames according to a first predictive encoding to generate encoded video data, the encoded video data including a prediction error based on the difference between a portion of a current video frame in the sequence and a first predictor thereof based on a first preceding video frame in the sequence; generating auxiliary video data related to the portion of the current video frame; and transmitting the encoded video data and the auxiliary video data to a receiver, the encoded video data being transmitted over a first channel, and the auxiliary video data being transmitted over a second channel. The step of generating auxiliary video data includes calculating a correlation between the first predictor and a predetermined second predictor based on a second preceding video frame in the sequence, the second preceding video frame preceding in the sequence the first preceding video frame.

Abstract: An apparatus for locating the point of impact of a body on a surface comprises detecting means (12; 12a, 12b, 12c, 12d) adapted to detect pressure waves generated by the interaction of said body with said surface, and a processing unit (15) operatively connected to said detecting means (12; 12a, 12b, 12c, 12d); the detecting means (12; 12a, 12b, 12c, 12d) and the processing unit (14, 15) are configured for detecting and processing power values associated with said pressure waves so as to calculate the position of said point of impact as a function of the aforementioned power values. Also described is the related method.

Abstract: A method and a computer program product for identifying the domains, selecting for each domain one domain-specific search engine and data source to be involved, generating the domain-specific subqueries for each selected search engine, defining a strategy for sending requests to each search engine and data source, and receiving, merging and ranking results. The result of the multi-domain query is a list of combinations, where every combination consists of a tuple of data, each relative to one of the domains of the query; such data is present in the results returned either by search engines or by data sources. The method provides the combinations having the highest combination score, as computed by a monotone aggregation function over the combinations.
