Problems solved by technology

However, it is generally difficult to continuously support numerous network services due to insufficient hardware resources of CE devices, inability to install other than a limited number of programs, and continuous increase in development costs and support costs.
[0011] In addition, in the case of using the technology of Patent Document 1, although the above-mentioned problems can be solved, information other than information directly representing data such as animation and music, in other words, the number of times of commentary and viewing times, etc. The functions provided by the service server, such as obtaining additional information on data, searching functions, and comment posting functions, have been deleted.
In this way, CE equipment can only provide a very small part of the functions originally provided in network services

Embodiment 1

[0077] figure 1 It is a diagram of a home theater system showing an example of the usage behavior of the Internet service reproduction device according to the first embodiment of the present invention. The home theater system shown in the figure includes a playback device 101 , a remote controller 102 , a display 103 , a removable medium 104 , and a recording medium 105 . Here, the playback device 101 corresponds to the Internet service playback device of the present invention. In addition, the display 103 can be used as a part of the Internet service reproduction device of the present invention.

[0078] The playback device 101 is used in a home theater system to provide movie works. For example, the reproduction device 101 obtains content data such as a movie through the removable medium 104, the recording medium 105, or the Internet. Then, in accordance with instructions from the remote controller 102 or the like, video is displayed on the display 103 and sound is output...

Embodiment 2

[0208] In Embodiment 1, there is such a problem that when the network service application instructs the reproduction of the content data selected by the user, and the reproduction device does not have the ability to reproduce the content data, although the user has made a selection, the selected content The data is not reproduced, thereby giving discomfort to the user.

[0209] In the second embodiment of the present invention, a playback device is provided with a playback abnormality notification unit, and when playback of specified content data fails, a method of notifying a network service application of playback failure to reduce discomfort to the user is described. .

[0210] Figure 19 is expressed in image 3 A diagram showing the internal structure of the second embodiment of the AV reproduction control unit 303 .

[0211] The AV reproduction control unit 303 includes a request acceptance unit 1601 , a data analysis unit 1602 , a data processing unit 1603 , an outpu...

Embodiment 3

[0223] There is such a problem in Embodiment 1 and Embodiment 2 that when the Internet service application instructs the reproduction of the content data selected by the user, if the reproduction device is unable to reproduce the content data, even if the user selects, However, the selected content data cannot be reproduced, which gives discomfort to the user.

[0224] In Embodiment 3 of the present invention, it is described that by including a type judging part, the application judges the type of content data to be reproduced; A method of reducing discomfort to the user.

[0225] Figure 21 It is a diagram showing the internal structure of the playback device 101 according to the third embodiment of the present invention. Additionally, regarding having image 3 Components that have the same functions as the components to be described are given the same numbers and descriptions are omitted.

[0226] regeneration device 101, in addition to utilizing image 3 In addition t...

Abstract

Disclosed is a link server (201) that is provided with a service data acquisition unit(352) for acquiring first data having a first format from an external service server (202) for providing data accumulated in a database through an electrical communication line; a data conversion unit (353) for converting the first data into second data having a second format which is usable by a program operating upon a reproduction device; and a communication control unit (351) for transmitting the second data converted by the data conversion unit (353) to the program operating upon the reproduction device (101).

Description

technical field [0001] The present invention is a technique for easily adding reproducible web services to CE (Consumer Electronics: Consumer Electronics) devices. Background technique [0002] In general, a CE device has insufficient hardware resources such as CPU performance and memory capacity compared with a PC (Personal Computer: personal computer). Therefore, in order to make an application running on a PC work on a CE device, measures such as reducing the functions of the application or reducing versatility are usually taken to reduce required hardware resources. [0003] With regard to such CE equipment, playback devices equipped with a BD (Blu-ray Disc)-ROM playback function including a Java (registered trademark) virtual machine have been widely used in recent years. ) performance of the degree to which the virtual machine works. However, considering that CE devices with the same functions as HTML (HyperText Markup Language) browsers working on PCs have not yet b...
