• a user accesses an IPTV server, which provides the IPTV PVR service, using the mobile terminal, which can receive the IPTV PVR service, at step Sl.
• the IPTV server After the access has been completed by the user's mobile terminal at step Sl, the IPTV server transmits a list of PVR services, which can be provided, to the mobile terminal, and enables the mobile terminal to output the list and, then a user selects PVR service which provides desired content from among the various services provided by the IPTV server at step S2.
• the IPTV server that provides the PVR service transmits information about the size of desired content for the selected PVR service and the encoding of the content to the user's mobile terminal at step S3.
• the user's mobile terminal searches the internal memory area thereof and checks the currently available storage space in the mobile terminal at step S4.
• the mobile terminal which has checked the available storage space, receives the information about the size of content for the PVR service, which is desired by the user, and the encoding of the content, which is transmitted at step S3, and displays the two pieces of information, that is, the size of content for the PVR service, which is provided by the PVR server, and encoding information, and the size of storage space that is currently available in the user's mobile terminal on a display screen.
• menu items for executing a storage space editing function for obtaining sufficient storage space are output along with the displayed information at step S5.
• the user compares the size of content for the PVR service, which is provided by the PVR server, the encoding information, and the currently available storage space, which are output to the display screen of the mobile terminal at step S5, and determines whether it is necessary to create more storage space at step S6.
• step S6 If, as a result of the determination at step S6, it is determined that it is necessary to create storage space, the user obtains storage space by performing editing, such as deleting data stored in the memory area of the mobile terminal, through the selection of the menu items for executing the editing function for the storage space output to the display screen of the mobile terminal. Thereafter, the process returns to step S4 and the processing is repeated. That is, in this process, the user conducts a task of deleting or arranging content previously stored in the mobile terminal, and thus the available storage space of the mobile terminal can be obtained at step S7.

• step S6 determines whether the content for the PVR service can be stored. If, as a result of the determination at step S6, it is determined that available storage space, in which the content for the PVR service selected by the user can be stored, remains in the mobile terminal or it is determined that available storage space, in which the content for the PVR service selected at step S2 can be stored, is obtained in the storage space of the mobile terminal through the editing of a storage space at step S 7, the user selects the content for the PVR service output to the display screen of the mobile terminal at step S8. In this process, the mobile terminal determines whether the content for the PVR service can be stored at step S9.

In this case, the process returns to step S5, and the processing from step S5 to step S9 is repeated. Thereafter, the mobile terminal displays information about the currently available storage space and the size of the content and a screen through which the editing of the storage space of the mobile terminal can be selected.
