专利汇可以提供Frequency interleaved video multiplex system专利检索，专利查询，专利分析的服务。并且Two video signals having substantially all their energy distributed at the same discrete line harmonics are interleaved to form a multiplexed output. One signal is processed to form a modified signal whose alternate lines are phase inverted so that its energy spectrum is displaced by one-half line frequency from the original harmonics. The modified signal and the other unprocessed signal are algebraically added to produce the multiplexed output. After transmission, the signals are separated by comb characteristic filters and inverse processing reconstructs the original signal.，下面是Frequency interleaved video multiplex system专利的具体信息内容。
1. A multiplex transmission system having first and second independent synchronized video input signals consisting of a series of portions, each portion being representative of a line of an image, and the video input signals having spectra consisting of energy distributed substantially within a common frequency range at common frequency harmonics, comprising: means for processing the first video input signal to produce a processed signal having alternate portions phase inverted, said first video signal remaining within the common frequency range during the processing, the processed signal having a spectrum consisting of energy distributed substantially within the common frequency range at frequency harmonics displaced midway between the common frequency harmonics; a summing means for algebraically combining signals applied to its inputs to form a multiplexed output signal; a first comb characteristic filter for applying the processed signal to one input of said summing means; a second comb characteristic filter for applying the second video input signal to the other input of said summing means, said summing means producing a multiplexed signal at its output having the frequency spectrum of the processed signal interleaved in the common frequency range with the frequency spectrum of the second video input; means for transmitting the multiplexed signal; means for separating the multiplexed signal after transmission with a combination comb filter into two signals according to their respective frequency spectra, the two signals being substantial duplicates of the processed signal and the second video input signal; and means for phase inverting alternate segments of the duplicate of the processed signal to produce a substantial duplicate of the first video input signal.
2. A system as claimed in claim 1 wherein said means for processing said first video input signal comprises: delaying means for delaying the first video input signal for a period substantially equal to the period of one portion of the first video input signal and producing a delayed first video input signal; an inverting means for producing a delayed phase inverted version of the first video input signal from the delayed first video input signal; and switching means for alternately selecting portions of the delayed phase inverted version of the first video input signal and the first video input signal itself.
3. A multiplexer comprising: sources of two independent synchronized video inputs of the type consisting of a series of portions each representative of a line of an image, each input having a spectrum consisting of energy distributed substantially within a common frequency range at common frequency harmonics; means for processing one of said two inputs to produce a processed signal having alternate portions, each representative of a line of an image, phase inverted so that its spectrum is modified and its energy is distributed substantially within said common frequency range about the midpoints of the gaps between said common frequency harmonics, the signals remaining within said common frequency range during processing; and means for combining said processed signal and the other of said two inputs to form a multiplexed output substantially within the common frequency range and having the frequency spectrum of said other input, said means for combining comprising a summing means and two comb characteristic filters for connecting the processed and unprocessed signals to the input of the summing means.
