    摘要： In a cable television system of the type wherein a cable television signal including free and restricted television channels is subjected to selective frequency conversion at individual terminal units to obtain a desired one of the channels for observation, a signal detector is provided for detecting the presence or absence of a polling signal from the central facility and the frequency converter is either disabled or adjusted for reception of a free channel if no polling signal is received.

    摘要： A television scrambling system of the GSS type includes a false key signal to defeat pirate decoders. The false key is placed approximately one half a horizontal line period following the last horizontal sync pulse preceding the vertical blanking interval of the television signal. If the pirate decoder is set to attenuate the video portion of the picture signal in response to receipt of a standard GSS scrambled signal, the pirate decoders will attenuate only the sync portion of the picture signal in response to a signal scrambled with the false key.

    摘要： A sentence forming apparatus forms a plurality of semantically equivalent sentences simultaneously in a plurality of languages by a conversational system. The apparatus includes a semantic dictionary memory which stores a plurality of indexes in a first language, a plurality of words in the first language semantically in coordination respectively with the indexes and grammatical information relating to the respective words, and first language syntax dictionary memory and second language syntax dictionary memory which store information concerning grammatical syntax and word in the corresponding language. A selection menu is formed based on the contents of the semantic dictionary. The apparatus further includes first language sentence assembler and second language sentence assembler which assemble, respectively, the first language sentence and the second language sentence utilizing the information concerning the grammatical syntax and word in the respective languages, in accordance with the selection menu.

    摘要： A fail-safe CATV system center facility in which abnormalities in a normal down-data signal transmitter are automatically corrected for so that there is no loss of reception at the terminal units. FM and AM detectors detect the presence or absence of the normal FSK data signal. The outputs of the FM and AM detectors are AND'ed together then delayed to control the switch state of a switch which selects between the outputs of the normal down data signal transmitter and a back-up transmitter for coupling through to the cable system. The back-up transmitter produces a clock signal which is obtained by modulating a carrier signal having the same frequency as that of the normal down data signal, preferably a frequency shift keyed signal.
