Here, supposed before summary reproduces operation, handling load in low relatively period, such as watch operating period or waiting time in standard, video reproducing apparatus 1020 is carried out the reception and the record of video content, the generation of the program information table that is recorded is reproduced rule and is determined table, the acquisition and the renewal of reproducing the Rule Information table, reproducing sectional management information or the like.

Below explanation is used for the operation that the video content summary reproduces.

Figure 30 is the flow chart that the process that is used to carry out definite segmentation reproduction order that the video content summary reproduces is shown.

At first, utilize remote controller, user's instruction video reproducer 1020 executive summaries are reproduced.

User instruction obtains the summary reproduction instruction (step S1101) that unit 1208 acquisitions provide by remote controller.

User instruction obtains unit 1208 and transmits the summary reproduction instruction to reproduction units 1209, and reproduction units 1209 obtains this summary reproduction instruction.

Reproduction units 1209 provides the segmentation reproduction order to determining unit 1207 and determines instruction.

Determining unit 1207 is at first checked its TV programme of reproducing of beginning to make a summary is not exceeded simultaneously reproduction counting (step S1102).

Here Tong Shi reproduction count table is shown with how much summary reproduction videos are simultaneously displayed on the reproduction screen.In current execution mode, the value of reproduction counting simultaneously is set to " 6 ".

The number that reproduces video when making a summary exceeds reproduction counting (in the "No" of step S1102) simultaneously, and this processing finishes.

The number that reproduces video when summary does not exceed reproduction counting (is ＂ at the ＂ of step S1102) simultaneously, and determining unit 1207 judges whether the TV programme that will be played summary also stays (step S1103) among the TV programme in the program information table that is recorded.

When this TV programme does not keep (denys ＂ at the ＂ of step S1103), this processing finishes.

When this TV programme is retained (is ＂ at the ＂ of step S1103), determining unit 1207 reads the programme information that is recorded (step S1104) of TV programme from the program information table T1000 that is recorded.

Determining unit 1207 is determined table T1010 with reference to reproducing rule, obtain and the corresponding rule ID (step S1105) of school ID in the programme information that is recorded that reads, and read the reproduction Rule Information (step S1106) corresponding with this rule ID from reproduction Rule Information table T1020.

And determining unit 1207 is from reproducing the reproduction Rule Information that Rule Information table T1020 obtains to have rule ID ＂ 001 ＂.

Determining unit 1207 obtains the reproduction sectional management information (step S1107) corresponding with the information type in the reproduction Rule Information that reads.

Next, determining unit 1207 is determined segmentation reproduction order (step S1108) based on the ＂ reproduction order ＂ in the reproduction Rule Information that obtains and the reproduction sectional management information of acquisition.

Reproduction units 1209 is according to the segmentation reproduction order displaying video content of being determined by determining unit 1207 (step S1109).

Supposing to be selected as the TV programme that will be played summary at step S1104, is the TV programme with the up-to-date record date-moment in the program information table T1000 that is recorded shown in Figure 26.

TV programme has program ID and programm name ＂ news program 1 ＂ of value ＂ 6 ＂.

Because the school ID of ＂ news program 1 ＂ is ＂ 001 (news) ＂, determining unit 1207 determines that from reproducing rule table T1010 acquisition value " 001 " is as rule ID at step S1105.

Because the value of rule ID is " 001 ", be " customer presentation information 1 " in step S1106 determining unit 1207 from reproducing Rule Information table T1020 identifying information type, reproduction order is " sequence of importance ", and the recovery time is " 10 minutes ".

In present example, when information type is " a customer presentation information 1 ", reproducing sectional management information accordingly is reproduction sectional management information T1030 shown in Figure 29.

Utilize the reproduction sectional management information T1030 of Figure 29, determining unit 1207 is determined the segmentation reproduction order, make segmentation with the highest importance values, be that segmentation ID is that the segmentation of numerical value " 3 " at first is played, and the segmentation with segmentation ID " 1 ", segmentation ID " 2 " and segmentation ID " 4 " is play subsequently by described order.

When reproduction order is ＂ age order ＂, determining unit 1207 is determined the segmentation reproduction order, makes from having the segmentation of minimum shift time, the played in order segmentation of pressing shift time.

Figure 31 is reproduction order tabulation T1040, and it illustrates last segmentation reproduction order.Reproduction order tabulation T1040 is produced according to the segmentation reproduction order of determining at step S1108 by determining unit 1207.

Reproduction order tabulation T1040 is the zone that is used to store at least one set of segmentation ID, shift time and recovery time.

Here, the recovery time T1041 with reproduction segmentation of segmentation ID " 1 " is " 00:02:00 ", is not " 00:03:00 ".This expression TV programme be recorded in TV programme a minute after beginning the time, and first minute of the TV programme that is not recorded of compensation.

And because according to reproducing Rule Information table T1020, total recovery time is to be predefined for 10 minutes, the recovery time T1042 with reproduction segmentation of segmentation ID " 4 " only is two minutes.

Figure 32 illustrates the example that the summary that is shown by display device 1030 reproduces screen.

Summary reproduces video and shows in each of video display area 1091 to 1096.

For example, above-mentioned ＂ news program 1 ＂ shows in video display area 1901, " movie program 2 " shows in video display area 1902, " movie program 1 " shows in video display area 1903, " drama programs 2 " shows in video display area 1904, " cartoon program 1 " shows in video display area 1905, and " drama programs 1 " shows in video display area 1906.

In explanation display frame 1911 to 1916, the Lower Half of summary reproduction screen is presented at the programm name of the video content that shows in the video display area 1901 to 1906.

Figure 33 is the demonstration example that reproduces a display video in the picture at summary.
