- Figure 3 shows the timing lag during packet transfer that occurs when passing through a digital line.
- a trigger signal strg is set at a position prefetched by a pre-set time rs. Is engraved.
- the prefetch time s is the time required for trigger signal detection processing 501 required in affiliated station 120, the time required for switching processing for material replacement 503, and the margin for securing margin 5 This is the sum of 0 and 2, for example, set to 3 seconds.
- the trigger signal strg will be imprinted at the position pre-empted by pkt 3. This is based on the probability that packets pkt1 to pkt3 are transmitted via the line during time r s without excess or deficiency.
- the packet arrival intervals of packets pkt1 to pk73 fluctuate due to time fluctuations of packet arrival intervals caused by overload or the like during transmission.
- packets pkt1 to pkt3 are received as packets pkt1, to pkt3 'when the affiliated station 120 receives the packet, and the timing is delayed by jjt. Therefore, the packet pkt 3 ′ does not end even if the predetermined prefetch time r s has elapsed since the detection of the trigger signal str g.
- the flow of the replacement material cfl to cf 15 is automatically switched after a predetermined prefetch time ⁇ s from the detection of the trigger signal strg, so that the packet P kt 3 ′ does not end. This causes the inconvenience that the cut-out cut shown in the figure occurs.
- the replaced material cfl ⁇ cf 15 (for example, CM material for 15 seconds) ends.
- the original material cm1 to cm15 flowing in the broadcast cell evening remains due to the timing delay described above without remaining the packet cm15.
- R sd will be broadcast. That is, there is an inconvenience that a part of the original material, which should not originally appear, remains and is broadcasted without being deleted.
- the disadvantage is that some of the remaining commercials appear.
- the delay due to the time fluctuation is described as an example. However, the same applies to the case where the time fluctuates, and when the switching is performed by transmitting the stream, the switching may be more unnatural.
- the conventional broadcasting system may not only impair the dignity of the broadcast content, but also impair the impression of the sponsor providing the program.
- FIG. 4 is an explanatory diagram thereof.
- Key station 1 110 issues a switching signal at 18: 59: 57: 3 three seconds prior to 19: 00: 00: 00 which should be switched from the program to the key CM. Then, the signal is transmitted to the affiliated station 12 which is a local station via the analog line 102, but the switching signal arrives at the affiliated station 120 due to a line delay. If the time is 59: 58: 8, the automatic switching control unit 122 of the affiliated station 120 executes automatic switching three seconds after the arrival of the switching signal, so the actual switching is scheduled. Instead of 19:00:00, which had been done, it will be executed at 19:00:01, which is delayed by the delay.
- the first problem with the conventional broadcasting system is that the quality of the broadcast content is degraded due to a problem that occurs when the material is switched at each station.
- scheduler (scheduling device) and scheduler
- the affiliated station's automatic transmission equipment detects a trigger signal from the broadcast cell received from the key station and, based on this trigger signal, switches the material under real-time control to reorganize the broadcast content unique to the own station Function was essential.
- the third problem with the conventional broadcasting system is that the cost increases because equipment and personnel are required for trigger signal detection and broadcast content reorganization at each affiliated station.
- the fourth problem of the conventional broadcasting system is an increase in cost due to the fact that each affiliate requires personnel associated with spare automatic transmission equipment. Spare equipment is operated in an emergency, but multiple affiliated stations each have spare equipment, so the total number of spare equipment will increase, and these spare equipment will not be able to operate frequently Therefore, the operation efficiency was extremely low and a method for rationalization was required.
- a certain affiliated station for example, station A
- station B another affiliated station
