Embodiment approach 1

[0083] Below, based on Figure 1 to Figure 15 One embodiment of the present invention will be described in detail.

[0084] 〔Overview of the system〕

[0085] First, based on figure 1 The outline of the content transmission and reception system according to this embodiment will be described. figure 1 Showing one embodiment of the present invention, it is a block diagram showing the configuration of main parts of a client (reproducing device) 1 and a server (generating device) 2 included in the content transmitting and receiving system 3 .

[0086] As shown in the figure, the client 1 is equipped with: a client control unit 10 for centrally controlling the operation of the client 1, a client storage unit 11 for storing data used by the client 1, and a device for the client 1 to communicate with an external device through a network. A client communication unit (communication unit) 12 that performs communication. In addition, the client control unit 10 includes a content sel...

example 2

[0142] Next, based on Figure 5 Another example of an MPD including a combination attribute combining three or more representations will be described. Figure 5 It is a diagram showing another example of an MPD including a combination attribute combining three representations.

[0143] In the illustrated example, with Figure 4 Similarly, representations #1 to #3 belong to group 1, representations #4 to #6 belong to group 2, and representations #7 to #9 belong to group 3.

[0144] here, in Figure 5 2 combination_required are described in #1 and #2 manifestations. Specifically, in the presentation of #1, combination_required for combinations #4 and #5, and combination_required for combinations #7 and #8 are described. In addition, in the representation of #2, combination_required that sets the objects of combination to #5 and #6, and combination_required that makes the objects of combination #8 and #9 are described.

[0145] Because combination_required is an attribute th...

example 3

[0179] Next, based on Figure 9 An example of an MPD including combination_required and combination_optional for combining three or more representations will be described. Figure 9 It is a diagram showing an example of an MPD that combines three representations including combination_required and combination_optional.

[0180] Except that the attribute of the combination in the manifestation of group 1 becomes combination_optional, Figure 9 MPD with Figure 4 The example is the same. exist Figure 9 In the example, the combination attribute of the representation of group 1 is set to combination_optional, and the reproduction of the representation of group 1 alone can be performed.

[0181] That is, client 1 is running from Figure 9 When the MPD of MPD selects #1 manifestation, it becomes #1, #1+#4, #1+#5, #1+#7, #1+#8, #1+#4+#7, Any one of nine combinations of #1+#4+#8, #1+#5+#7, and #1+#5+#8 is reproduced.

[0182] This kind of MPD can be suitably applied to a case w...

Abstract

A client (1) includes: a content selecting section (13) for selecting contents in accordance with Attributes of combination included in an MPD, that indicate combinations of contents to be reproduced simultaneously; a request executing section (14) for requesting a server (2) to send the selected contents; and a content reproducing section (15) for reproducing the contents sent from the server (2) in response to the request, in the selected combination.

Description

[0001] This application is filed with the State Intellectual Property Office of China on January 6, 2012, entitled "Reproducing device and its control method, generating device and its control method, recording medium, data structure, control program, and recording medium recording the program" A divisional application of Application No.201280004852.7. technical field [0002] The present invention relates to a playback device or the like that plays back content acquired through a communication network, and more specifically, relates to a playback device or the like that determines content to be acquired by referring to description information including information on the content. Background technique [0003] Conventionally, technologies for providing content through a communication network have been widely used. For example, Patent Document 1 below discloses a content streaming service system in which a request for content is sent from a client to a server using HTTP, and ...
