Abstract

A controller makes a demultiplexer select a transport stream corresponding to user'"'"'s operation, and supplies it to a VTR through an I/F circuit. The I/F circuit of the VTR gives the transport stream to a recording/reproducing unit for recording, and transmits EIT data to a TV to supply them to a program guide GUI generating part. The GUI generating part generates GUI data based on the inputted EIT data, and makes them stored in a cassette memory using a cassette memory unit of the VTR. At the time of reproduction, GUI data read by the cassette memory unit is supplied to the program guide GUI generating part, and a program guide display of programs recorded on a cassette tape is displayed. In this manner, guide information on programs recorded on a cassette tape is automatically displayed.

Claims

1. An apparatus for displaying recorded contents, comprising:

a plurality of devices connected on a network;

a first recording device included in one of said plurality of devices, which records program data inputted in one of said plurality of devices;

a second recording device included in one of said plurality of devices, in which program guide information that relates to said program data is inputted and which records or stores said program guide information on a predetermined recording medium on which said recording device records or in a storing medium which relates to said predetermined recording medium;

a device using an application program interface which can be commonly owned by one or more devices in said network, said device being able to read and write list data prepared in correspondence with said application program interface based on said program guide information recorded on said recording medium or stored in said storing medium using said application program interface; and

an updating device which updates said program guide information recorded on said recording medium or stored in said storing medium based on list data written by said application program interface.

2. An apparatus for displaying recorded contents according to claim 1, further comprising a display data generating device which generates display data to display a guide display about programs recorded on said predetermined recording medium based on said list data which is read using said application program interface.

3. An apparatus for displaying recorded contents according to claim 2, further comprising a display device which displays said guide display based on said display data.

4. An apparatus for displaying recorded contents according to claim 3, wherein said display device includes a device which uses said guide display as a graphical user interface and controls a selecting operation by a user and said first recording device.

5. An apparatus fir displaying recorded contents according to claim 2, wherein said display data generating device generates retrieving data for retrieving programs recorded on said predetermined recording medium based on information read by said second recording device from said predetermined recording medium or said storing medium.

6. An apparatus for displaying recorded contents according to claim 1, wherein said recording medium is a cassette tape, and a storing medium related to said recording medium is a cassette memory.

7. An apparatus for displaying recorded contents according to claim 1, wherein said recording medium is a DVD disk, and wherein said second recording is the one for recording information based on said program guide information in a TOC area of said DVD disk.

8. An apparatus for displaying recorded contents according to claim 1, further comprising a transmitting device which transmits changed list data to the device using said application program interface when written in the list data by said application program interface.

9. An apparatus for displaying recorded contents according to claim 1, further comprising an informing device which informs the device using said application program interface that said list data is changed when written in the list data by said application program interface.

10. An apparatus for displaying recorded contents, comprising:

a device using an application program interface which can be commonly owned by one or more devices in a network on which a plurality of devices are connected, said device being able to read and write list data prepared in correspondence with said application program interface based on program guide information recorded in a predetermined recording medium by the devices in said network, from other devices using said application program interface; and

an updating device which updates said program guide information stored in said predetermined recording medium based on the list data written by said application program interface.
