摘要:
A method for controlling a musical medley function in a karaoke television includes steps for randomly selecting song from a class of songs having similar form or theme, and continuously playing songs from the selected class. The user sets a minimum reference mark and the target number of challenging songs. Each song performed is graded, thus allowing the singer to proceed to a next song only when the graded mark exceeds the reference mark. The method includes a step for providing a celebrator message and fanfare when the number of played songs equals the target number of challenging songs, thereby prompting the user to take added interest in singing. The method is adaptable in karaoke televisions and is particularly useful in household karaoke televisions.

This invention relates to the process for producing ortho-isopropylated phenol derivatives having following general formula (VIII). ##STR1## (in the above formula, R.sub.1 is a hydrogen or a low alkyl group of C.sub.1 -C.sub.4)A process for producing ortho-isopropylated phenol derivatives (VIII) of the present invention is characterized by obtaining position isomer desired by means of Claisen rearrangement of phenyl allyl ether without catalyst in atmosphere, and then obtaining only one isomer by oxidation and reduction of the above-obtained position isomer. According to the present invention, ortho-alkylated phenol derivatives (VIII) having high purity at low temperature and low pressure can be prepared without producing a by-product and requirement of the complicated separation procedure.
