Abstract

In a video signal recording apparatus, information about a video commercial program or message (CM) is recorded in the vertical blanking interval (VBI) of the video signal constituting the commercial message so that the information remains with the commercial program or message even during subsequent editing. Video signals representing a plurality of commercial messages and having respective information in the vertical blanking intervals are serially recorded on a master tape while generating stop code data and recording the stop codes in a longitudinal track on the master tape. Further, a video signal reproducing apparatus is described which can extract data from the VBI and longitudinal track of a tape, process the data and automatically terminate the reproduction after reproducing a stop code.

Claims

1. A video signal recording apparatus supplied with at least one video signal having vertical blanking intervals and constituting a plurality of programs, and with information data relating to the contents of the respective programs, comprising:

first time code generating means for generating first time code data including bits in which a material code indicative of an attribute of a respective one of said programs is formed, said attribute being selected from a group consisting of a title and a sponsor of said respective one of said programs;

inserting means receiving said video signal and said first time code data for providing an output signal in which said first time code data are inserted into a predetermined period in at least a selected one of said vertical blanking intervals of said video signal;

second time code generating means for generating second time code data including bits in which stop control data are formed; and

recording means for recording said output signal of said inserting means on a video track of a master recording medium and for recording said second time code data on a longitudinal track of said master recording medium such that said stop control data are positioned on the longitudinal track in a predetermined relation to a location on said video track in which said material code is recorded by the recording means such that, when said stop control data are read during a reproducing operation said attribute is reliably displayed.

2. A video signal recording apparatus according to claim 1, wherein each of said programs consists of a first abandoned cut area for providing a boundary ahead of the respective program, a program video signal portion used for recording of said respective program, a second abandoned cut area for providing a boundary after said respective program and a black burst signal formed serially in the order named.

3. A video signal recording apparatus according to claim 2, wherein said material code indicative of an attribute of a respective one of said programs is inserted in the vertical blanking intervals of said program video signal portion.

4. A video signal recording apparatus according to claim 3, wherein said material code is inserted a predetermined number of times.

5. A video signal recording apparatus according to claim 1, wherein said first time code generating means includes means for forming a user'"'"'s control code in said bits of said first time code data.

6. A video signal recording apparatus according to claim 1, in which said recording means includes:

first recording means for recording said output signal from the inserting means on a preliminary recording medium;

reproduction means for reproducing said output signal from said preliminary recording medium thereby generating a preliminary signal; and

second recording means for recording said preliminary signal on said video track of said master recording medium and for recording said second time code data on said longitudinal track of said master recording medium.
