Abstract: An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context. The apparatus receives an input from the user and other data. A predicted input is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback. Also provided is a pattern recognition system for a multimedia device, wherein a user input is matched to a video stream on a conceptual basis, allowing inexact programming of a multimedia device. The system analyzes a data stream for correspondence with a data pattern for processing and storage. The data stream is subjected to adaptive pattern recognition to extract features of interest to provide a highly compressed representation which may be efficiently processed to determine correspondence.

Abstract: In a method for error recognition of a digital bit data stream transmitted by a transmitter to a receiver, a digital bit data stream coded with a convolution coder is quantized to hard bit values. The hard bit values are read in in a forward feedback-coupled inverse shift register that is inverse to the generator shift register used for the coding, and yield a first result word. In a chronologically reversed sequence, the bit data stream is read into a reverse feedback-coupled inverse shift register, which yields a second result word. The two result words are exclusive OR-combined with one another in the same time orientation to form an error syndrome. The error syndrome indicates a set of possibly faulty bit positions in the bit data stream. A transmission rate that is increased in relation to known methods results, since apart from the tail bits, which are used anyway, no additional redundancy is required for the error handling.
