Problems solved by technology

[0009] In Patent Document 1, since the occurrence of such a power supply cutoff is not considered, when the power supply is cut off in a device that is performing cooperative processing, then resulting in the inability to complete collaborative processing
[0010] In addition, according to Patent Document 2, even if the power supply to the device in the cooperative processing is cut off, it is possible to switch to an alternate device to continue the cooperative processing, However, it is unavoidable that cooperative processing is interrupted by switching to an alternate device
Interruption of such cooperative processing is a problem in high real-time processing, such as recording processing of TV programs transmitted from broadcasting stations (cooperative processing between devices receiving TV programs and devices recording video)

Embodiment approach 1

[0125]

[0126] The information processing system according to Embodiment 1 is obtained by improving a conventional information processing system in which a plurality of devices connected to a network cooperate to process a processing request from a user.

[0127] Each device installed in a general household, etc. may be operated by the user of each device at an arbitrary timing by turning off the main power switch provided on the device or pulling out the power cable. , will cause the collaborative processing to stop.

[0128] Therefore, the information processing system according to this embodiment is configured such that a device that receives a processing request from a user (hereinafter referred to as an "indicating device") selects a power source that satisfies a predetermined level from other devices (hereinafter referred to as a "processing device"). The processing device of the supplied reliability reference is a device that cooperates with the instruction device (h...

example 1

[0225]

[0226] In Embodiment 1, a method was described in which the instructing device 200 selects a cooperative object device using the power supply attribute table 500, wherein the above-mentioned power supply attribute table 500 includes a plug-in / unplug-in / out-possibility 502 indicating whether each processing device can pull out a power cable from a power outlet. and an estimated insertion / removal probability 503 indicating the probability level of insertion / removal.

[0227] Hereinafter, a modified example in which the power supply attribute table 500 is replaced with a power supply attribute table composed of different items will be described focusing on differences from the first embodiment.

[0228]

[0229] Hereinafter, the power supply attribute table used by the pointing device 200 will be described.

[0230] Figure 8 It is a diagram showing an example of the data structure and contents of the power supply attribute table 800 .

[0231] The power supply att...

Embodiment approach 2

[0245]

[0246] It has been described above that the processing device 300 according to Embodiment 1 transmits the electric power information stored in advance in the storage unit 306 to the instruction device 200 .

[0247]In the processing device according to Embodiment 2, when the execution unit 303 of the device detects that power is supplied from a commercial AC power source, the content of the power information stored in the storage unit 306 is updated every time the detection is detected, and the updated power The information is sent to the pointing device according to the second embodiment. Hereinafter, the difference from Embodiment 1 will be mainly described.

[0248]

[0249] First, the functional configuration of the pointing device according to Embodiment 2 will be described.

[0250] The pointing device 200 according to the second embodiment basically has the same structure as the pointing device 200 according to the first embodiment. However, with regard t...

Abstract

A table information receiving unit (201) of an instructing device (200) receives a device name of a processing device from each processing device connected with a network, function information on functions with which its device is provided, and power information indicative of assurance of power supply to the device, and reflects them on a table stored at memory unit (202). An analyzing unit (204) analyzes contents of a processing request from a user when the analyzing unit receives the processing request, and sends an execution control unit (205) necessary function information indicative of functions necessary for carrying out processing corresponding to the processing request. The execution control unit (205) judges whether it is necessary to work in cooperation with other processing devices on the basis of the received necessary function information and, if necessary for cooperation, selects a processing device expected to stably supply power as a cooperation subject processing device in accordance with the table stored at the memory unit (202).

Description

technical field [0001] The present invention relates to cooperative processing technology among a plurality of devices connected to a network. Background technique [0002] In recent years, cooperative processing has gradually begun to be carried out between TV receivers and popular electric appliances such as DVD / HDD (Hard Disk Drive: Hard Disk Drive) players which can be connected to the network. For example, a user can make a video recording reservation for a DVD / HDD player by operating a TV receiver displaying a program table through a remote controller or the like. [0003] As cooperative processing technologies between devices, there are Patent Document 1 and Patent Document 2, for example. Briefly describe these techniques. [0004] In Patent Document 1, in a content recording system in which a plurality of video recording devices are connected to a network, when a certain video recording device records a plurality of videos provided in the same time zone, when it i...
