Abstract

In order to make a recording mode in case of recording a broadcast program to be a mode which is easily used when reproducing, guide information of the broadcast program of the recorded channel is obtained in a case when a received broadcast program is recorded and a pointer is set according to the obtained guide information at a recording position of the time from which each program is started in a case when a plurality of programs exist during a period from the recording start time to the ending time thereof.

Claims

1. A program data recording method for recording a received broadcast program comprising:

obtaining and storing guide information of a broadcast program in a recorded channel;

setting predetermined pointers at recording positions of time points on which respective programs are started in a case when a plurality of programs exist during a period from a recording start time to an ending time thereof according to the obtained guide information; and

recording said pointers by making a connection with said guide information.

2. A program data recording method according to claim 1, wherein it is constituted on an occasion of reproduction such that recording programs can be reproduced from said set positions of the respective pointers.

3. A program data recording method according to claim 2, wherein also said guide information is recorded together with the program data and it is made possible to display a recording program list according to the recorded guide information.

4. A program data recording apparatus comprising:

receiving means for receiving a broadcast signal of a predetermined broadcast service;

recording means for recording the broadcast signal received by said receiving means;

guide information obtaining means for obtaining and storing guide information of a program broadcasted by said broadcast service; and

control means for obtaining the guide information relating to the program which is being recorded by said recording means from said guide information obtaining means, for setting predetermined pointers at recording positions of time points in which respective programs are started in a case when a plurality of programs exist during a period from a recording start time to an ending time thereof according to the obtained guide information, and for recording said pointers by making a connection with said guide information.

5. A program data recording apparatus according to claim 4, wherein said control means carries out a control for reproducing recording programs from said set positions of the respective pointers when reproducing the programs recorded by said recording means.

6. A program data recording apparatus according to claim 5, wherein said recording means records also the guide information of the program recorded at that time together with the program data and said control means carries out a control for displaying a recording program list according to the recorded guide information.
