Server device, and method and program for processing on the same

摘要

A server device which makes a function equivalent to its own function available on an old-generation client device inferior in functionality includes a request receiving unit which receives from the client device a request for processing using a function which the client device lacks, a device status determination unit which determines whether or not the server device is capable of the requested processing depending on statuses indicated by status information tables, and, when it is determined that the server device is capable of it, specifies alternative processing corresponding to a function for the requested processing among functions of the server device with reference to a function information table, an alternative-processing providing unit which performs the specified alternative processing, and a transmission unit which transmits data generated through the performing of the alternative processing to the client device.

1. A server device comprising:
a transmitter that transmits an encoded content item to a client device; a request receiver that receives, from the client device, a request for processing a content item using a function lacking from the client device, during a period in which the client device uses the content item; a function information storage that stores function information, the function information indicating, for each of functions which said server device includes, alternative processing for obtaining, using a function which the client device includes, a result identical to a result of processing performed using the function which said server device includes; an alternative-processing specifier that specifies alternative processing for enabling a video to be displayed, the alternative processing being specified with reference to the function information, the specified alternative processing corresponding to a function to be used for the requested processing from among the functions which said server device includes; a decoder that decodes the content item; an alternative processor that generates a content item for special playback by performing, as image processing on the decoded content item, the specified alternative processing for enabling a video to be displayed, the content item for special playback being a content item which is different from the decoded content item and is to be reproduced by the client device using a normal play back function as a video identical to a decoded video reproduced by said server device using a special function which is included in said server device and lacking from the client device; and an encoder that encodes the content item for special playback generated from the decoded content item through the performance of the specified alternative processing by said alternative processor, wherein said transmitter transmits, to the client device, the encoded content item for special playback encoded by said encoder.
