Abstract: The invention relates to a method and system for performing content-aware deduplication of video files and content storage cost optimization. The method includes pre-processing video files into a plurality of groups of video files based on type of genre and run-time of a video. The genre of a plurality of video files is automatically detected using a sliding-window similarity index, which is utilized to improve accuracy of genre detection. After the pre-processing step, each group of the plurality of groups of video files are simultaneously fed into a plurality of machine learning (ML) instances and models which measure a degree of similarity corresponding to each group of video files by detecting one or more conditions that exists in the video files. The one or more conditions are detected by performing deep inspection of content in the video files using hash-based active recognition of objects.

Abstract: A tour guide system includes a radio receiver section adapted to receive a plurality of preselected signal frequencies and an automatic frequency selecting means for tuning the receiver only to one of the preselected frequencies whose signal strength exceeds a predetermined amplitude. The receiver section essentially comprises an antenna stage, a tuning stage, a signal amplitude detecting stage, an expander stage, and an audio transducer stage. The automatic frequency selecting means comprises a level detector having an input connected to the output of the receiver detector stage, an astable multivibrator having an input connected to the output of the level detector, a shift register having an input connected to the output of the astable multivibrator and having a plurality of output of each stages, each connected to a field effect transistor (FET) in the tuning stage of the receiver. The tuning stage of the receiver comprises a plurality of capacitors and FET's in parallel with a common inductance.

Abstract: An electronic tour guide system including means for suppressing objectionable crosstalk and noise is described. Crosstalk suppression is achieved by means of a comprssor in the transmitter and an expander in the receiver. Objectionable noise between loops is eliminated by means of a squelch circuit which reduces power drain whenever the received signal is below a certain threshold. The transmitter and receiver are designed to handle a plurality of information signals simultaneously. For example, a listener can select one of several different languages broadcast within an antenna loop. The transmitting loop antenna is matched in impedance to the output of the channel means in the transmitter so that maximum power transfer is obtained. Each receiver is further equipped with a gravity operated mercury switch which turns off power to the receiver when the receiver chasis is inverted.
