    摘要: A magnetic recording and reproducing apparatus of a cassette type has a first and a second recording mode converting a luminance signal of a video signal into an FM luminance signal having a first and a second carrier frequency and recording the FM luminance signal on a magnetic tape respectively. When the FM luminance signal is to be recorded according to the second recording mode, a magnetic tape having an excellent short wavelength recording characteristic is used for recording. A cassette containing this magnetic tape is provided with a configurational feature on its upper or lower half, and a detector for detecting this feature is disposed in the apparatus. When the detector detects that a magnetic tape is adapted for recording according to the first recording mode, the FM luminance signal is recorded according to the first recording mode, but when the detector detects that the magnetic tape is adapted for recording according to the second recording mode, the user can select either the first recording mode or the second recording mode as desired. A discriminating circuit is disposed in the reproducing system to discriminate as to whether the FM luminance signal was recorded according to the first recording mode or the second recording mode, and, on the basis of the result of discrimination by the discriminating circuit, the reproduced FM luminance signal is automatically processed in a processing circuit with a processing characteristic corresponding to the recording mode.

    摘要: A video tape recorder enables a normal video signal for an aspect ratio of 4:3 or a wide-picture video signal for a greater aspect ratio of, for example, 16:9 to be selectively recorded/reproduced onto and from a magnetic tape. In order to identify which of the aspect ratios the reproduced video signal is based on, a recording mode signal indicative of the aspect ratio is recorded on the magnetic tape together with the video signal. A code signal or a pilot signal is used for the recording mode signal. In the reproducing operation, the aspect ratio of a reproduced picture is recognized from the recording mode signal, and a signal indicative of the aspect ratio is delivered to an external device, such as a television set, together with reproduced video/audio signals. In a case where the reproduced picture is a wide picture and where the external device does not conform to the wide picture, the aspect ratio of the video signal is changed. A television set suited to the features of the video tape recorder is also disclosed.

    摘要: In a high-speed routing control system, plural path candidates each leading to a destination node are selected on the basis of physical connection information of links connecting respective nodes in a path candidate selection unit 11, and a path candidate containing no congestion-occurring link is specified as the optimum path from the plural path candidates selected by the path candidate selection unit 11 in an optimizing unit 12. Accordingly, even when the destination node is nearer to the self node, the optimum path selection can be performed, and a switching operation to a bypass path can be performed at high speed. In addition, the traffic amount based on topology information can be suppressed, and the large-scaling of the network can be supported.
