摘要： A memory system for a television receiver is disclosed. The memory system contains an array of addressable memory cells, each row of which can contain one line of sampled video signals. The number of rows in the array is greater than the number of lines in a frame. Apparatus is included in the memory system for simultaneously writing more than one line of samples into the memory, for simultaneously reading more than one line of samples from the memory, or for both. Simultaneous access to multiple lines allows the reading and writing of multiple corresponding lines of samples from both the current and the prior frame. The row addresses that are used to store the lines of samples for a frame are not the same for each frame, rather the lines of each new frame are stored in rows with lesser addresses than the rows used for the prior frame. This introduces a backward scrolling of the stored image from frame to frame which avoids overwriting data to be used in time-domain or spatial-domain filtering done directly from memory.

摘要： A widescreen television signal having left side, right side and center panel information is converted into a signal compatible with a standard television system, such as NTSC. In the compatible signal, center panel information is expanded to occupy the standard display region seen by a viewer, side panel low frequency information is compressed into the horizontal overscan region, and side panel high frequency information modulates an alternative subcarrier other than the chrominance subcarrier.

摘要： A television sync signal generator adapted for ready conversion among various television standards includes a memory in which information related to the amplitude of at least one component of a composite sync signal is stored at address locations each corresponding to at least one particular time in each recurrent television frame. A clock signal generator addresses the memory to sequentially read out the information so the sync signal can be reconstructed. For reducing the number of memory addresses required, each memory address contains information relating to the instantaneous resolution or clock rate. A sample rate controller is coupled to the memory for having the instantaneous clock address rate controlled in response to the contents of the memory.

摘要： Graphics for television display which emphasize circles, ellipses, circular or elliptical arcs, and the radii of circles or ellipses are conveniently stored in image memories addressable in polar coordinates. Television images which are to be rotated are conveniently stored in such memories, so the angular coordinate of the image memory addresses can be incremented or decremented to rotate the image with hardware as simple as a single adder. To read image memories addressed in polar coordinates, the Cartesian coordinates descriptive of television raster display are scan-converted to polar coordinates. This scan conversion takes place in real time at video sampling rates. The generation of the angular coordinate of the polar coordinates is facilitated by dividing one Cartesian coordinate by another by differentially combining their logarithms as found from read-only-memory table look-up, then finding an arc tangent from the logarithm of their difference as found from further read-only-memory table look-up. Since the non-linearities of the logarithm and arc tangent functions tend to track each other to a degree, combining the anti-logarithm and arc tangent look-up steps in a single read-only memory provides greater angular resolution for number of bits used in the read-only-memory input addresses.
摘要翻译：强调圆，椭圆，圆或椭圆弧的电视显示图形以及圆或椭圆的半径方便地存储在以极坐标方式寻址的图像存储器中。要旋转的电视图像被方便地存储在这样的存储器中，因此图像存储器地址的角坐标可以被递增或递减，以使硬件像图像一样简单地旋转图像。要读取极坐标中寻址的图像存储器，将描述电视光栅显示的笛卡尔坐标扫描转换为极坐标。该扫描转换在视频采样率下实时进行。通过将一个笛卡尔坐标除以另一个笛卡尔坐标，通过差异地组合它们的对数（从只读存储器表查找中找到），然后从它们的差异的对数中找到反正切来促进极坐标的生成从进一步的只读内存表查找。由于对数和反正切函数的非线性倾向于在一定程度上彼此追踪，所以将单个只读存储器中的反对数和反正切查找步骤组合在一起，为只读存储器输入地址。

摘要： The present application discloses a video signal processing apparatus for minimizing cross-color and cross-luminance interference in a composite video signal. A first filter is coupled to a color difference signal input terminal and generates a signal occupying a first region of a predetermined spatio-temporal frequency space. A second filter is coupled to a brightness signal input terminal and generates a signal occupying a second region of the predetermined spatio-temporal frequency space exclusive of the first region. An encoder forms a composite video signal from the filtered color difference and brightness signals such that they occupy mutually exclusive spatio-temporal frequency spaces. A television receiver for decoding the composite video signal is described which comprises the serial connection of a vertical-temporal filter and a horizontal filter. Filters are also disclosed for the first and second filters described above which are the serial connection of vertical-temporal filters and a horizontal filter. Specific vertical-temporal filter arrangements are also disclosed.

摘要： Apparatus is disclosed for reducing unwanted jagged diagonal artifacts in a video signal. At an encoder, moving image information is intraframe averaged over a given frequency range, e.g., above 1.5 MHz, while still image information is subjected to a field repeat process over a given frequency range. At a decoder, still image information is subjected to a frame repeat process over the given field repeat frequency range, while moving image information is left unchanged.

摘要： A system for expanding/compressing a video signal includes a dual-port memory having read and write address inputs and a video signal input. A pixel counter provides a pixel location signal to the write address input of the dual-port memory, and to a programmed memory device (e.g., a PROM) including a look-up table. The memory device is programmed to provide a time expanded/compressed version of the pixel location signal in accordance with a programmed time expansion/compression factor, which is applied to the read address input of the dual-port memory. A time expanded/compressed video signal is developed at the output of the dual-port memory.
