    • An extended definition television (EDTV) system transmits, receives and displays both EDTV and NTSC signals using a NTSC channel bandwidth. The system procudes an EDTV broadcast signal having a picture with a 16:9 aspect ratio and at least one adjacent horizontal border to produce an overall image apsect ratio of 4:3. Picture information is also selectively modulated onto the horizontal border. The EDTV broadcast signal is transmitted in a NTSC format, and a receiving circuit is provided comprising a display with a 16:9 aspect ratio, a detector for determining whether an EDTV or other type of signal is being received, and an expansion circuit responsive to the detector to produce an expanded picture for display. When an EDTV signal is received, it is expanded and filtered vertically and is expanded horizontally and the 16:9 picture is displayed on the 16:9 display. The receiving circuit derives picture information from both the picture portion and the border portion of the EDTV signal. When an NTSC signal is received, it is displayed on the 16:9 display with at least one vertical border so that the NTSC picture has a 4:3 aspect ratio. The EDTV signal is also compatible with and may be received and displayed on standard NTSC receivers as a 16:9 picture with at least one horizontal border.

    • An interpolated line is created between the horizontal lines of each field of an interlaced television signal on a pixel-by-pixel basis. For each pixel to be interpolated, the pixel in the same field located immediately above and below the interpolated pixel are compared. If the difference between the two values exceeds a predetermined difference, the larger or the smaller pixel value is picked for the interpolated pixel, depending upon the value of the corresponding pixel in the immediately previous field. If the difference between the two pixel values is smaller than the reference value, either of the two values or an average of the two values may be used as the interpolated pixel value.
    • 在逐个像素的基础上,在隔行电视信号的每个场的水平线之间产生插入线。 对于要插值的每个像素,比较位于内插像素正上方和下方的相同场中的像素。 如果两个值之间的差超过预定的差值,则根据前一场中的相应像素的值,对于内插像素挑选较大或较小的像素值。 如果两个像素值之间的差小于参考值,则两个值中的任一个或两个值的平均值可以用作内插像素值。

    • A complex television system is provided for accommodating at the same time both highly technically oriented and less technically oriented users of the system. The system includes a state of the art complex television, a complex remote control transmitter device for use by the technically oriented user in both programming and, if desired, controlling the television, and a simple auxiliary remote control transmitter device for the less technically oriented user. The simple auxiliary remote control transmitter device has a minimum of keys, such as power-on, channel-up, channel-down, volume-up, and volume-down, as well as a switch which identifies the user. Different power-on and channel-up and down codes for each switch position is provided by the simple auxiliary remote control transmitter device, and each such code is different than the corresponding codes of the complex remote control transmitter device. In this manner, a microprocessor in the television will recognize which user is in control. By using the complex remote control transmitter device, values for personal preference parameter and/or channel rings associated with each user may be entered and stored in a programmable memory of the television. Then, when the television recognizes the power-on code for a particular user, the personal preference parameter and/or channel rings are immediately accessed. In this manner, less technically oriented users may be the beneficiaries of complex personal preference rings programmed by them by a highly technically oriented user, and will only have to deal with a simple auxiliary remote control transmitter device to control the television.

    • A conventional peaking signal derived by delaying the incoming video or luminance signal first by one horizontal line delay and then by a second horizontal line delay is modified by multiplication with an adaptive factor. The adaptive factor is derived by first taking the difference between the incoming signal and the twice delayed signal, then deriving the magnitude or the square of this difference and multiplying this by a factor K empirically derived for the particular display device. The resultant signal is then subtracted from unity. This yields the factor by which the conventional peaking signal is multiplied. The conventional signal multiplied by this factor constitutes the final peaking signal which is added to the 1H delayed luminance signal to yield the desired peaked luminance signal.
    • 通过将输入视频或亮度信号延迟一个水平行延迟然后再延迟第二水平行延迟而导出的常规峰值信号通过与自适应因子相乘来修改。 通过首先获取输入信号和两倍延迟信号之间的差异,然后导出该差值的幅度或平方,并乘以由特定显示器件经验导出的因子K,得出自适应因子。 然后从单位中减去得到的信号。 这产生了常规峰值信号乘以的因素。 乘以该因子的常规信号构成最终峰值信号,其被加到1H延迟亮度信号以产生期望的峰值亮度信号。
