Abstract

A recording apparatus includes a delivery schedule information acquisition section, an update reservation section, and an update data acquisition section. The delivery schedule information acquisition section acquires information on a delivery schedule of update data for updating control software, the update data being delivered from an update delivery server by an IP multicast system. The update reservation section generates, based on the information on the delivery schedule acquired by the delivery schedule information acquisition section, acquisition reservation information of the update data. The update data acquisition section acquires the update data based on the acquisition reservation information generated by the update reservation section.

Claims

1. A recording apparatus, comprising:

a delivery schedule information acquisition section to acquire information on a delivery schedule of update data for updating control software, the update data being delivered from an update delivery server by an IP multicast system;

an update reservation section to generate, based on the information on the delivery schedule acquired by the delivery schedule information acquisition section, acquisition reservation information of the update data; and

an update data acquisition section to acquire the update data based on the acquisition reservation information generated by the update reservation section.

2. The recording apparatus according to claim 1, further comprising:

a program information acquisition section to acquire information on a program delivered from a program delivery server;

a program selection section to prompt a user to select a program to be set to a recording reservation using the information on a program acquired by the program information acquisition section;

a recording reservation section to generate recording reservation information of data of the selected program; and

a recording reservation information storage section to store the recording reservation information generated by the recording reservation section,

wherein the update reservation section generates the acquisition reservation information of the update data based on the information on the delivery schedule acquired by the delivery schedule information acquisition section and the recording reservation information stored in the recording reservation information storage section.

3. The recording apparatus according to claim 2,

wherein the update data is delivered repetitively from the update delivery server, and the information on the delivery schedule contains information on all delivery dates/times of the update data that is delivered repetitively, and

wherein the update reservation section generates the acquisition reservation information by determining a delivery date/time of the update data based on the information on the delivery schedule acquired by the delivery schedule information acquisition section and the recording reservation information stored in the recording reservation information storage section.

4. The recording apparatus according to claim 2,

wherein the update data is delivered repetitively from the update delivery server, and the information on the delivery schedule contains information on all delivery dates/times of the update data that is delivered repetitively, and

wherein the update reservation section-presents to the user the information on a program and the information on the delivery schedule of the update data, prompts the user to select one of the delivery dates/times of the update data, and generates the acquisition reservation information using data of the selected one of the delivery dates/times.

5. A software update data acquisition method, comprising:

acquiring information on a delivery schedule of update data for updating control software, the update data being delivered from an update delivery server by an IP multicast system;

generating, based on the acquired information on the delivery schedule, acquisition reservation information of the update data; and

acquiring the update data based on the generated acquisition reservation information.

6. A medium storing a program to cause a computer to function as:

a delivery schedule information acquisition section to acquire information on a delivery schedule of update data for updating control software, the update data being delivered from an update delivery server by an IP multicast system;

an update reservation section to generate, based on the information on the delivery schedule acquired by the delivery schedule information acquisition section, acquisition reservation information of the update data; and

an update data acquisition section to acquire the update data based on the acquisition reservation information generated by the update reservation section.

7. A data delivery system, comprising:

a recording apparatus; and

an update delivery server to deliver data of a delivery timetable of update data for updating control software of the recording apparatus, the update delivery server delivering the update data by an IP multicast system,

the recording apparatus including

a delivery schedule information acquisition section to acquire information on a delivery schedule of the update data for updating the control software, the update data being delivered from the update delivery server by the IP multicast system,

an update reservation section to generate, based on the information on the delivery schedule acquired by the delivery schedule information acquisition section, acquisition reservation information of the update data, and

an update data acquisition section to acquire the update data based on the acquisition reservation information generated by the update reservation section.
