A karaoke reproducing apparatus is equipped a measure for easily checking whether a music piece selected by the user has correctly been accepted or not. The apparatus has a memory in which music title name information of each of the music pieces recorded on a recording medium has previously been stored. When one of the plurality of music pieces is selected by an operation, the music title name information of the selected music piece is soon displayed by characters. The apparatus also has memory means in which music piece classification information of each of the music pieces recorded on the recording medium has previously been stored. An item content selection command to designate the contents of at least one of a plurality of different items included in the music piece classification information is generated in accordance with an operation. The music piece corresponding to the contents of at least one item indicated by the item content selection command is searched for by using the information from the memory means.

A method of recording compressed and coded data is designed to improve the speed and ease of random accessing, and to reduce the buffer capacity and facilitate control and editing in the reproducing system. The method comprises the steps of compressing and coding video signals for every predetermined number of frames with the amount of codes per predetermined number of frames being constant; storing the predetermined number of frames of compressed and coded video signals into at least one video packet; storing the video packet in a pack having a time slot corresponding to the predetermined number of frames (preferably at the end of the pack); and recording the video signals on the recording medium in a pack stream containing such packs, with the relation between the size of the pack and the size of the logical block of the recording medium being set to 1:n (n: an integer) and the relation between the size of the pack and the size of the physical block of the recording medium being set to 2:m (m: an integer).

A synchronizing system with a simple structure accomplishes synchronous reproduction without complicating a control circuit for synchronizing video and audio signals with each other. The number of unit audio data blocks to be put in one pack is set in such a way that the difference between the presentation start times for the stream of video data and the stream of audio data in one pack in a predetermined pack period becomes a predetermined value, and the pack carries positional information of the pack in the predetermined pack period to the pack. In a reproducing apparatus, the difference between presentation start times for video signals and audio signals in each pack is acquired by referring to positional information (AAU sequence number) in a stream of packs, transferred by the above transmission method, and at least one of the presentation start times for video signals and audio signals in the stream of packs is controlled so that the difference between the presentation start times coincides with the difference between the presentation start times corresponding to the positional information.

Synchronizing system for time-divided video and audio signals

A karaoke reproducing apparatus for recording singing sound together with karaoke play sound, has a facility of printing information on the recorded musical program. The karaoke reproducing apparatus has a memory which contains previously stored recorded music information including at least the title, songwriter's name, and composer's name for each of musical programs recorded on the recording medium. In response to a recording start command, the recorded music information corresponding to a musical program selected by an operation is read from the memory, and output to a printer. Since recorded music information can be printed on a printed member such as a label and preserved as a record when singing sound is recorded together with karaoke play sound, the label, if adhered to a recording medium on which the sound is recorded, allows the user to readily know the recorded contents afterward. According to another aspect of the invention, a karaoke reproducing apparatus has a memory which contains copy right information on each of musical programs recorded on a recording medium. For a recording prohibited musical program, its karaoke play music can be prevented from being recorded so as to appropriately protect the copy right thereof.

Karaoke reproducing apparatus

A karaoke reproducing apparatus which allows a user to specify one vocal part or both vocal parts of two parts when one piece of music selected from a plurality of pieces of music by the user is a multi-audio type, reproduces only instrumental accompaniment (karaoke) when both parts are specified, and reproduces the vocal sounds of an unspecified one of the two parts together with the instrumental accompaniment when only one part is specified.
