Abstract

PURPOSE:To use a cassette tape at consecutive transmission by recording plural TV advertisement programs into a tape rewinding or fast forwarding in a prescribed unit time. CONSTITUTION:Plural recording regions (blocks) 1a, 1b...1m are provided on a cassette tape T. Then the length of the blocks 1a, 1b...1m is selected to N set of unit recording area 2 able to record the shortest CM in, e.g., 15sec, for example, 10 sets. The length is a length possible for rewinding or fast forwarding the tape in the shortest CM time 15sec. The same kind of CM is recorded to the unit recording area 21-2n of an optional block, e.g., 1b of the cassette tape T. The other blocks are not used for the day, and in this case, they can be blank and other CM sent to other same day can be recorded. In using the cassette tape in this way, consecutive transmission is attained without causing blank time.

Conventionally, in television broadcasting stations, a system has been known in which a large number of cassette tapes are played back in program order using a plurality of VTRs in order to continuously and automatically send out advertising programs called commercial messages (CM). ing.

The shortest commercial commercial length is 15 seconds, and some commercials are twice or four times longer than the shortest length, such as 30 seconds or 1 minute. “ [Problem to be solved by the invention] By the way, if you try to record and manage multiple commercials on one cassette tape, a 20-minute tape will have a length of 15 seconds, as shown in Figure 2. For example, 66 commercials can be recorded.

However, many Cs recorded on one cassette tape
Even if an attempt is made to continuously send out M using the system described above, depending on the order in which the CMs are sent out, the access time to the desired CM may take several tens of seconds, that is, several times the shortest CM time. The problem was that it was virtually impossible.

For example, if two VTRs are used, CM-As and CM-Af recorded at the beginning and end of one cassette tape, as shown in FIG. 3A, and CM-Af, respectively, as shown in FIG. CM-Af-4CM-Bm-CM-A recorded on the middle part of the other cassette tape.
When transmitting in the order of CM-As, after transmitting CM-A f is completed, CM-As must be accessed while transmitting CM-Bm.

However, if CM-Af and CM-As are recorded separately at both ends of the same 20-minute tape, the rewind time will be about 1 minute, and there will be a blank period of 30 seconds after the end of CM-Bm. will occur.
