Abstract: The present invention relates to a ring for extension hair, and it is desirable to include a upper ring and a lower ring in the for extension hair: the upper ring which has a first-penetration hole and is formed at a certain height; and the lower ring, which has a second-penetration hole, is formed at a certain height, is at to the side away from the lower part of the upper ring, and is connected by a connection piece connecting with the above upper ring. By the present invention, thanks to the advantage of simply and promptly treating the extension hair to the wearer's hair as well as of being able to treating the extension hair to wearer's hair on strand by strand, the ring for extension hair provides the advantages of soft movement while wearing the extension hair, of being able to attach the style as the wearer wants, and of being able to remove the extension hair without any pain.

Abstract: A multichannel scanning method for M-PIP TV system capable of displaying a plurality of sub-pictures on a main picture is disclosed which includes a first step of initializing the system, a second step of selecting and memorizing image video sources outputting image signals, a third step of successively outputting the image signals to a plurality of positions of the sub-pictures, and a fourth step of terminating the system operation in response to a multichannel scanning termination command. According to the method of the present invention, a multichannel scanning can be automatically carried out, and there is no possibility that a channel having no image signals can be outputted. Especially, even in the case where the number of channels to be scanned is larger than that of the displayable number of sub-pictures, scannings for the total amount channels can be carried out without being subjected to any restriction.

Abstract: A mixed simulcast circuit in which the voice signal demodulated in the voice demodulator through the tuner and the voice signal from the outside can be recorded on the recording medium according to the user's desire, then reproduced selectively. The mixed simulcast circuit has first means for recording a signal which is received in the tuner and demodulated in the demodulator, second means for recording the modulated voice signal on the one channel of the recording medium and for recording the voice signal from the external on the other channel thereof, and means for switching selectively one signal, either the voice signal which is demodulated and recorded from tuner or the voice signal, which is recorded from the external, when it reproduced.

Abstract: An automatic-shift circuit for a sub-picture screen for PIP feature is disclosed. The circuit includes;a brightness signal separator device for separating only the brightness signal from the composite video signal for the main picture screen; a brightness level comparison device for selecting the character brightness level and the width thereof from the separated brightness signals; and a identical position comparison device for determining whether the character brightness width is detected at the identical position. The circuit also includes a device for setting the vertical and the horizontal timing; a counter for counting the field number where character brightness width is detected at the identical position and for generating the automatic shifting signal if the field number counted is beyond the predetermined value; and a microcomputer for controlling the PIP processing unit so as to shift the sub-picture screen upon receipt of the automatic shifting signal.
