摘要： A chroma-key insertion technique by which a part of a second television picture, designated by a chroma-key signal produced from a first television picture, is inserted into the first television picture. The second television picture is displayed on a television monitor which is inserted into the chroma-key frame advantageously allowing a television announcer to always face or direct his eyes toward the chroma-key screen in which a picture from a remote video source is to be inserted on a resultant picture.

摘要： A tracking system for producing special effects in a television picture by inserting a second television picture into a first television picture. The first and second pictures are represented by first and second video signals. A key signal representing a key frame to be positioned on the first picture is produced and the electrical noise is removed from the key signal. A position signal having two horizontal position signal values and two vertical position signal values is produced and represents the position of a circumscribed frame of the key frame. A compressed second video signal representing a compressed second picture is produced in response to the second video signal and the position signals. The horizontal and vertical position signals produce a frame signal, and the frame signal is applied to the noise removing circuitry. In response to the key signal the first video signal and the second video signal are combined to produce the special effects.

摘要： A scrambling apparatus which scrambles a television signal prior to its transmission to prevent interception of the signal by means other than a counterpart descrambler apparatus. The television signal is scrambled by dividing each scan line (a scan line includes its leading sync portion) into first and second portions which are divided by an intermediate picture element. Each line is transmitted as follows: first the intermediate picture element is transmitted followed by the second scan line portion, followed by the first portion which begins with the sync signal and is terminated by retransmission of the intermediate picture element. The position of the intermediate picture element is randomly changed in each successive scan line so that reconstruction of the original television signal becomes exceedingly difficult. In the descrambler (receiver), a random address generator which includes a read only memory which contains the sequence of the position of the intermediate picture element in successive scan lines is used for receiving the scrambled television signal and descrambling the signal and restoring it to its original form for use in standard television receivers.
摘要翻译：一种加扰装置，其在传输之前对电视信号进行加扰，以防止除对方的解扰器装置以外的装置拦截信号。通过将每个扫描线（扫描线包括其前同步部分）划分成由中间像素分割的第一和第二部分来加扰电视信号。每行如下传送：首先中继图像元素被发送，随后是第二扫描线部分，之后是以同步信号开始的第一部分，并且通过中间图像元素的重传而终止。中间像素的位置在每个连续的扫描线中随机地变化，使得原始电视信号的重建变得非常困难。在解扰器（接收机）中，随机地址生成器包括一个只读存储器，其中包含连续扫描行中的中间像素的位置的序列，用于接收加扰的电视信号并对信号进行解扰并将其恢复到其中原始形式用于标准电视接收机。

摘要： A phase locking system locks at least one incoming composite video signal to the synchronizing signals of a second, reference wave. The incoming signal is strobed at a rate dependent upon the incoming color subcarrier into a memory, essentially on a field-by-field basis. Circuitry is provided by grouping the fields on a repeating field-tagged basis (groups of four for the NTSC signal format) to maintain signal integrity.

摘要： An improved phase locking system in which an independently reproduced video signal is coded into a digitized video signal in response to a first clock pulse train, the first clock pulse train being produced from a synchronizing signal and/or a color burst signal contained in the video signal. The digitized video signal is stored and storage location as well as delay prior to storage is controlled in response to the phase difference between the synchronizing signal and a reference signal. The improved phase locking system reduces the frequency of occurence of visual shifts on the reproduced television picture.

摘要： A chromakey signal producing apparatus is disclosed. A color to be keyed is set as a first reference color and a color not to be keyed is set as a second reference color. A clear chromakey signal is automatically produced by discriminating the difference between the first and second reference colors. According to the invention, even when a part of the TV picture has a color similar to that of the part to be keyed, a clearly discriminated chromakey signal is produced without the need for any complicated sensitivity factor judgment, simply by designating the color of that particular part as the second reference color corresponding to the maximum sensitivity.

摘要： A digital transmission system wherein a signal to be transmitted is represented by a plurality of parallel data bits, each of said data bits having a positional significance ranging from a most significant data bit to a least significant data bit. Each of said data bits are assigned to one of a plurality of data transmission highways based on the positional significance of the data bit. Failure of a particular highway results in a reassignment of the data bits to the highways so that transmission degradation is minimized.
