摘要： A speed-up circuit time compresses and interlaces field delayed and interpolated lines of a video input signal for display in progressive scan fashion. The interpolated lines are produced by adding low and high frequency components derived from the video input signal. The low frequency component is produced by frame-combing and low pass filtering the input signal. The high frequency component is obtained by field delaying, line comb filtering and low pass filtering the input signal. The combined low and high frequency components are spatially and temporally coincident thereby reducing the visibility of motion artifacts (double images) on the display.

摘要： A frame comb type composite video decoder which does not require motion adaptive processing circuitry generates low frequency luminance signal components from one field of composite video signal. The high frequency luminance component is derived from two lines of composite video signal from each of two fields disposed before and after the field from which the low frequency luminance signals is developed.

摘要： Method and apparatus for producing a frozen television picture are disclosed. Successive fields of picture information are generated by an interpolator which is responsive to a video input signal. These successive fields are applied to the input of a first field store device. The video input signal is applied to the input of a second field store device so that the successive fields of the video input signal correspond in time to the successive fields generated by the interpolator. Lines from the respective field store devices are sequenced repetitively to form a video signal representing the frozen television picture. The interpolator generates fields which, when displayed with corresponding fields of the video input signal, minimizes motion-induced artifacts without unduly degrading vertical resolution.

摘要： An adder circuit is described for producing signals representative of the sum of large numbers of block-synchronized digital signals each of which may have any value within the range of quantizing levels represented. The adder circuit includes one or more binary counters coupled to count bits of the input signal having a particular significance. Counting takes place during an active interval such as a television field interval, and the counters are reset after each counting interval. The counter outputs are latched either before or after processing by addition of other counter outputs. The latched signal represents the sum of the values of the words in one sync block.

摘要： A television camera or other source of color-representative signals such as R, G and B includes a matrix to which the R, G and B signals are applied to form luminance (Y) and color-difference (I,Q) signals. The source and matrix are coupled together by way of a signal path having a particular response or transfer function for the R, G and B signals over their normal range. Unavoidable noise occurring in the signals near black level may perturb the color-representative signals, and causes color errors. The errors are reduced by arranging the coupling to have a response to negative noise peaks into the blacker-than-black region. The response outside this normal range is complementary to the response within the normal range. In a particular embodiment the coupling includes a gamma corrector which has complementary response in the blacker-than-black region.

摘要： A progressive scan receiver includes a frame interpolation filter for generating added lines for display in a given field from a video input signal by interpolation from corresponding elements of immediately preceding and following fields. A second filter provides a line interpolated signal having picture elements spatially and temporally coincident with corresponding elements of the frame interpolated signal and having a suppressed vertical detail component. A third filter attenuates the vertical detail component of the frame interpolated signal. An output circuit combines the signals of the three filters to provide a frame interpolated video output signal in which the vertical resolution of the video input signal is preserved and motion artifacts characteristic of frame interpolation are attenuated.

摘要： A television camera-recorder combination includes an imager which forms a signal representative of the image during an integration interval. The integration interval is followed by a pull-down interval during which the integrated signal is transferred out of the photoresponsive region. Streaking of an image displayed from the signal results from light falling on the photoresponsive region during the pull-down interval. A mechanical shutter periodically prevents light from falling upon the photoresponsive region of the imager. The shutter is synchronized with the pull-down interval. The synchronization and drive arrangement of the video recorder portion is mechanically coupled to the shutter to provide a common drive. In another embodiment, a color wheel associated with the viewfinder of the camera is mechanically coupled to the video recorder drive arrangement for common mechanical drive.

摘要： An improved transmission arrangement for a color television signal includes a time-division multiplexing apparatus for alternately presenting for transmission through a single channel baseband signals defining the chrominance information of the television signal. In order to provide improved resolution, a store is coupled to the signal source for storing at a writing rate a first of the baseband components during the time at which it is generated. A read generator is coupled to the store for reading the stored baseband component at a higher data rate than that at which it was generated. The baseband component is transmitted through the single channel at the higher data rate.

摘要： A video signal is serially enclosed for transmission in PCM form during synchronizing level intervals and encoded in a run length limited NRZ form during non-synchronizing level intervals, each PCM word being selected from minimum and maximum disallowed states of the NRZ code. In a decoder, a first detector responds only to the presence of the PCM code for synchronizing a second detector with response to both the NRZ and PCM coded portions of the encoded video signal to provide a decoded video output signal whereby the PCM portion of the signal conveys both decoder timing information and information as to a specific level of the video signal.

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.
