  • Patent number: 6292944
    Abstract: A method and apparatus for locating the source of noise ingress into a CATV system return path by coupling a filter having a passband in the noise frequency bandwidth to the nodes between adjacent return path amplifiers. The filter is sequentially coupled to the nodes, working away from the CATV system headend. A signal level meter or the like monitors the effect on the noise of coupling the filter to the nodes. When a node is reached at which coupling of the filter to the node no longer has any effect on the signal level in the node, the source of the noise is isolated in the node immediately preceding the node under test.

  • Patent number: 6279157
    Abstract: To obtain unique identification data to be added to program data even if different encoders are used, identification data generated by adding serial data specific to an encoder to data (time code) indicating the time of encoding is inserted into program data to be stored in a storage device. Whether the program data has been transmitted is checked based on the thus-generated identification data. By virtue of the use of such an identification data, even if program data are produced at the same time point by using different encoders, they can be clearly distinguished from each other because they are associated with different identification data because serial data of the encoders are different.

  • Patent number: 6269482
    Abstract: Methods of testing circuits for degradation of electrical signals and compensating for this degradation are disclosed. One such method involves visually comparing a visual representation of a reference signal generated by a test signal source, which can be made substantially identical to an original signal, and a degraded signal generated by another test signal source after passing through a video system. The degraded image is then adjusted to visually match the reference image. Another disclosed method involves converting a degraded signal that has passed through a video system into two substantially identical copies of said degraded video signal and then adjusting one of the two substantially identical copies of said degraded video signal to compensate for the degradation of the system while comparing it with the other substantially identical copy of said degraded signal which remains uncompensated.
