    摘要： A video processing device for automatic tuning of an audio-video signal (86) in accordance with a topic selection (80) made by a user. A user makes a selection of a subject matter topic from a menu (82) and the necessary tuning is thereafter automatically done under control of a menu control interface (82). In the example of digital information (90) transmitted in the vertical blanking interval of a video signal, the menu control interface (82) automatically adjusts the tuner (88) in accordance with the menu selection made by the user to choose an arbitrary channel and page of information within the channel. The menu or menus can be received from the incoming information, or can be stored in a memory (100).

    摘要： The present invention relates to a speech recognition system including Markov models which are adapted to be trained by an initial training label set and initial training speech using adaptation speech, and are used to recognise input speech. According to the invention, the system is characterised in that it comprises means for interpreting the adaptation speech into adaptation label strings using an adaptation label set; means for connecting each label in each of the adaptation label strings with each state or each state transition of a Markov model which corresponds to the adaptation label strings concerned; means for determining the confusion probability of each label in the initial training label set and each label in the adaptation label set being confused with each other, based on the connection between each label in the adaptation label set and each of the states or state transitions, and the parameter values of the Markov model concerned with the initial training set; and means for determining parameter values of each of the Markov models with respect to the adaptation label set, based on the confusion probabilities and the parameter values of the Markov model concerned with the initial label set.

    摘要： The present invention relates to an optical data storage apparatus comprising an optical data storage member, means for generating a light beam, means for directing the light beam onto the storage member for performing data storage and readback operations on the storage member, means for receiving a reflected beam of light from the storage member, means for detecting variations in the intensity of said reflected beam of light and for generating corresponding electrical signals, focus control means for controlling the focus of said light beam on the storage member, a servo mechanism for supplying a selected focus signal to the focus control means so as to produce a selected focus condition (31), and a calibrating system for calibrating the focus control means.
    According to the invention the storage apparatus is characterised in that the calibrating system comprises means for sequentially supplying to the servo mechanism a positive and a negative offset focus signal (FES OFFSET), means for measuring the values of the electrical signals (36.37) representing the intensity of the reflected light beam for each of the offset focus signals, means for determining the difference between the two electrical signal values, means for comparing the difference with a reference value, and means for supplying the offset signals to the servo mechanism to modify the selected focus condition (35) when the difference is less than the reference value.
