Embodiment Construction

[0046] The mode for carrying out the present invention (hereinafter referred to as "embodiment") is described below. At the same time, it is described in the following order.

[0047] 1. Example

[0048] 2. Deformation

[0049]

[0050] [Content delivery mode]

[0051] In this embodiment, the content is distributed from a content server (such as an Internet Protocol Television (IPTV) server) to a 3D compatible terminal (receiver) through a network (such as the Internet). First, the transmission mode (types 1 to 4) of the content proposed in this embodiment will be described.

[0052] [About Type 1]

[0053] First, "Type 1" is described. figure 1 The "Type 1" transmission mode is schematically illustrated. In "Type 1", the 3D content includes one file, which only includes the 3D stream. There is no 2D content, or if there is 2D content, this is prepared as another content without direct contact.

[0054] "Type 1" is the basic state of 3D content. Because all are 3D streams, it is no...

Abstract

A process of a 3D compatible terminal to which content is distributed is made convenient. Meta information and a control signal are transmitted together with content transmitted from a content server 10 in a predetermined transmission mode. The meta information includes information indicating whether the entirety of the content is 3D or a part thereof is 3D, information indicating whether this starts with 2D or 3D when a part thereof is 3D, and identification information of a 3D transmission method when the content is 3D. The control signal includes a signal for identifying 2D and 3D, that is, switching information regarding switching timing between 2D and 3D. An encoding unit 154 encodes the content stored in a content storage unit 151, the meta information generated by a meta information generating unit 152, and the control signal generated by a control signal generating unit 153 in a predetermined encoding system. The meta information is inserted into a meta file or an MP4 container, for example, to be transmitted.

Description

Technical field [0001] The present invention relates to a signal sending method, a signal sending device, and a signal receiving device, and more particularly to a signal sending method for distributing content through a network or the like. Background technique [0002] Researched the distribution of 3D content through the network. All 3D content is not always created by 3D signals. The 3D signal may be partially used. This is because in the case of very long content, if all the content is 3D, the audience will become tired and the creation of the content is expensive, and videos in which 3D expression is effective are limited. [0003] The strategy may be to separately produce content for 3D compatible terminals and for non-3D compatible terminals, and after confirming whether the terminal supports 3D in advance, provide content including 3D to the former and 2D content to the latter. Even when a user of a 3D compatible terminal watches a 3D program, the user does not necessar...
