摘要： A sampled color video signal is recorded in component form in a plurality of channels. The form of the signal is chosen so that if only one channel is available due to dropouts upon playback, then at least approximate separation into color components is possible, and if all channels are available, then full color separation is possible. The form is also chosen to provide a dynamic range that fits the transmission channel.

摘要： In order to reduce the amount of hardware required in comparing 8-bit numbers representing digitized video signals, only the four LSB are compared, since if the numbers differ by more than the four LSB, no comparison is desired. This is done by detecting if any of the four MSB are logic "1", and if so, setting all of the four LSB to logic "1".
摘要翻译： 为了减少比较代表数字化视频信号的8位数所需的硬件数量，只比较4个LSB，因为如果数字差别大于4个LSB，则不需要比较。 这通过检测四个MSB中的任何一个是逻辑“1”来完成，如果是，则将所有四个LSB设置为逻辑“1”。

摘要： A transmission line cable terminated at both ends is routed through a plurality of separate television cameras and a television monitor. Each camera includes a current source coupled to the cable. The video from the camera modulates the current source to produce a signal across the terminations without changing the impedance across the line.

摘要： A solid-state color imaging apparatus comprising a beamsplitter for splitting an incoming light beam representative of an image into at least first and second light beams corresponding to a first color band (e.g., green) of the incoming light and the first color band and a second color band (e.g., blue) of the incoming light, respectively, and first and second solid-state imagers disposed for receiving respective ones of the light beams. The first imager is optically offset with respect to the second imager and their output signals processed so as to develop an apparently improved resolution signal for light of said first color band when compared to the signal developed for light of said second color band.

摘要： A portable video recorder transduces video signals onto an elongated medium. The transducer-to-medium velocity is controlled by a rotary member such as a capstan, turntable or headwheel. In portable applications, motion of the recorder causes accelerations or variations in velocity of the rotary member which affects the regular spacing on the medium of sync or timing signals transduced thereto. Regular spacing of sync signals is desirable for good reproduction on playback. Timing or sync signals generated by the rotary members are used to control the rate of the timing signals of the video to be recorded as they are applied to the transducer, thereby making the spacing regular.

摘要： A wide-angle television system, such as one having 2:1 or 5:3 aspect ratios, provides N portions that exceed the limits of a conventional 4:3 aspect ratio picture in regions that are normally hidden from view in a conventional receiver. Further, a receiver is provided wherein the picture is changed from the wide-angle display to the standard display by collapsing the horizontal scanning only. In another arrangement standard definition kinescopes having aspect ratios of 4:3 are masked in a special manner to provide a 5:3 aspect ratio display which may be collapsed to provide a 4:3 standard aspect ratio pictures.

摘要： A video FM transmission system includes a transmitter coupled to a receiver by means of an FM transmission path subject to triangular noise effects. The receiver includes a coring circuit for reducing the noise and the transmitter includes a coring compensation circuit having a transfer function different from and not complementary to the transfer function of the coring circuit. The transfer functions are selected so as to effect greater coring of the triangular noise characteristic of the FM transmission system and lesser coring of the desired small-signal high-frequency components of the video signal thereby providing a desired signal-to-noise ratio enhancement of the video. In preferred embodiments of the invention the transfer functions of both the coring circuit and the coring compensation circuit are provided by programmed read only memories having different and non-complementary programs.

摘要： An encoder for digital video signals uses averages of pairs of transmitted samples to reconstruct untransmitted samples. The pair selected for reconstruction is selected in accordance with the criteria of least change around the untransmitted sample. If a plurality of averages are tied for least change, a priority order is used to select which average to use. For color video the priority order is preferably the horizontal, diagonal and vertical averages. A different order can be used for monochrome signals.
