Therefore, if the content to be distributed is a 3D image display section or a partial 3D image display section, or a partial 3D image display section, the 3D-compatible terminal starts with a 3D image display section.
- Information regarding whether it is a display section or a 2D image display section can be easily known prior to the reproduction of the content by this content information.
- switching information regarding the switching timing of the stereoscopic image display section and the two-dimensional image display section is transmitted together with the content.
- the switching information may be described inside the content and transmitted.

- IPTV Internet Protocol Television
- 3D-compatible terminal for example, the Internet.
- FIG. 1 conceptually shows this “type 1” transmission mode.
- all 3D content is composed of one file of only a 3D stream.
- This “Type 1” is a basic 3D content. Since the entire program is a 3D stream, it is not necessary to embed a control signal indicating 2D or 3D in the stream, or it is not necessary to monitor the control signal in a 3D-compatible terminal. However, if the entire content is produced as 3D, the degree of freedom is lost and the production cost increases.
- This “type 1” is a case where, when a non-scalable 3D system is applied as a transmission system, a 2D video is generated using only half of the stream image data when generating a 2D video from a 3D stream in a 3D compatible terminal. , Image quality deteriorates.
- the non-scalable 3D system includes a side-by-side (SBS) system and a top-and-bottom system.

- Type 2 like “Type 1”, if the entire contents are produced as 3D, the degree of freedom is lost and the production cost increases.
- type 2 can be switched from 3D to 2D in a 3D-compatible terminal even in the non-scalable 3D system by using simultaneous 2D content.
- the service can be provided with the original image quality.
- pairing information between 3D content and simul 2D content is required, and the operation and implementation associated therewith are complicated.

- a part of the content is a 3D image display section. That is, in this “type 3”, one content includes a 3D image display section and a 2D image display section.
- This “type 3” needs to embed a control signal for identifying a 2D stream and a 3D stream on the stream, and a 3D-compatible terminal needs to monitor this control signal and switch between 2D playback and 3D playback. .
- non-scalable 3D when “non-scalable 3D” is applied to “type 3”, viewing of a 2D image in a 3D image display section generates 2D video using only half of the stream in a 3D compatible terminal. Image quality deteriorates.
- viewing of 2D video on a 3D-compatible terminal can be performed seamlessly without degrading image quality.
- FIG. 4 conceptually shows this “type 4” transmission mode.
- This “type 4” is a transmission form assumed to be applied in the case of the non-scalable 3D system.
- “Type 4” by adding simul 2D content to “Type 3”, 2D images can be viewed in the 3D image display section without deterioration in image quality on a 3D-compatible terminal. .

1.実施の形態
2.変形例
[コンテンツの送信形態]
この実施の形態においては、IPTV(Internet ProtocolTelevision)サーバ等のコンテンツサーバからネットワーク、例えばインターネットを介して、3D対応端末(受信機)に、コンテンツが配信される。最初に、この実施の形態で想定するコンテンツの送信形態(タイプ1~タイプ4)について説明する。
最初に、「タイプ1」を説明する。図1は、この「タイプ1」の送信形態を概念的に示している。この「タイプ1」においては、3Dのコンテンツは、全て3Dストリームのみの1ファイルで構成されている。2Dのコンテンツは、無いか、あっても直接的な結びつきが無い単なる別コンテンツとして用意される。
次に、「タイプ2」を説明する。図2は、この「タイプ2」の送信形態を概念的に示している。この「タイプ2」は、ノンスケーラブル3D方式の場合に適用が想定される送信形態である。この「タイプ2」においては、3Dのコンテンツは、全て3Dストリームのみの1ファイルで構成されている。この3Dのコンテンツと対応付けされている2Dのコンテンツ(サイマル2Dコンテンツ)により、3Dから2Dへの切り替えを可能にした送信形態である。
次に、「タイプ3」を説明する。図3は、この「タイプ3」の送信形態を概念的に示している。この「タイプ3」においては、コンテンツの一部が3D画像表示区間となっている。つまり、この「タイプ3」においては、1つのコンテンツに、3D画像表示区間と2D画像表示区間が含まれている。
次に、「タイプ4」を説明する。図4は、この「タイプ4」の送信形態を概念的に示している。この「タイプ4」は、ノンスケーラブル3D方式の場合に適用が想定される送信形態である。この「タイプ4」においては、「タイプ3」に対して、サイマル2Dコンテンツを加えることにより、3D対応端末において、3D画像表示区間での2D画像の視聴を、画質劣化なく行うことが可能となる。
この実施の形態においては、コンテンツサーバからの上述した各送信形態のコンテンツの伝送に併せて、3Dに係るメタ情報および制御信号も伝送される。これらメタ情報および制御信号は、受信側において、上述したタイプ1~タイプ4の送信形態に対処するために用いられる。メタ情報および制御信号のそれぞれを説明する。
メタ情報は、コンテンツ全体に関する情報である。このメタ情報には、コンテンツ全体が3Dであるか部分的に3Dであるかを示す情報が含まれる。また、このメタ情報には、部分的に3Dである場合には、さらに先頭が2Dであるか3Dであるかを示す情報が含まれる。また、このメタ情報には、コンテンツが3Dである場合に、3Dの伝送方式を識別する情報が含まれる。3Dの伝送方式には、サイドバイサイド(Side By Side)方式、トップアンドボトム(Top & Bottom)方式、フレームシーケンシャル(Frame Sequential)方式、MVC(Multi View Coding)などがある。
制御信号は、映像ストリームや音声ストリーム(AVストリーム)を直接制御するための信号である。この制御信号には、コンテンツが部分的に3Dである場合に、2Dと3Dを識別する信号が含まれる。この識別信号は、2Dと3Dの切り替えタイミングに関する切り替え情報である。
メタ情報、制御信号の挿入位置について説明する。最初にメタ情報の挿入位置について説明する。メタ情報は、例えば、メタファイルの内部に挿入される(第1の方法)。また、メタ情報は、例えば、MP4コンテナ内部に挿入される(第2の方法)。また、制御信号は、MPEG4-AVCのビデオデータストリームを構成する各アクセスユニットのヘッダ部に挿入される。
図5は、メタ情報の挿入位置の第1の例を示す説明図である。この例では、コンテンツを再生するためのライセンス取得情報、コンテンツ取得情報などを含むメタファイル170に、メタ情報が記述されたメタ情報171が挿入されている。この場合、受信機は、メタファイル170からライセンス取得情報を得て、3Dコンテンツを再生するためのライセンスを取得する。また、この場合、受信機は、メタファイル170からコンテンツ取得情報を得て、3Dコンテンツを取得する。
図7は、メタ情報の挿入位置の第2の例を示す説明図である。この例は、MP4コンテナの内部にメタ情報を記述する場合について示している。図7では、moovコンテナの内部に「uuid CF3D」というユーザ定義のメタデータを用意し、この「uuid CF3D」にメタ情報を記述する。
図9は、制御信号の挿入位置を示す説明図である。この例では、MPEG4-AVCのビデオデータストリームを構成する各ユニットのヘッダ部に、制御信号が挿入される。この制御信号には、上述したように、部分的に3Dである場合に、2Dと3Dを識別する信号(切り替え情報)が含まれる。
図10は、上述の「タイプ1」の送信形態におけるコンテンツサーバのファイル構成例を概略的に示している。図10(a)は、メタ情報の挿入位置が第1の例である場合を示している。この場合、コンテンツサーバは、全体が3Dコンテンツのファイルと共に、メタ情報が挿入されたメタファイルを有している。一方、図10(b)は、メタ情報の挿入位置が第2の例である場合を示している。この場合、コンテンツサーバは、メタ情報が挿入された全体が3Dコンテンツのファイルを有するが、メタ情報が挿入されたメタファイルを有していない。
図14は、コンテンツサーバ10の構成例を示している。コンテンツサーバ10は、コンテンツ保存部151と、メタ情報生成部152と、制御信号生成部153と、エンコード部154と、送信部155と、を含んで構成される。
次に、上述したコンテンツサーバ10から配信される、タイプ1~タイプ4のコンテンツを受信する受信機20の構成例を説明する。受信機20としては、例えば、インターネットに接続できるテレビ受像機であってもよく、また、インターネットに接続できるパーソナルコンピュータ、携帯型の情報端末、例えば携帯型ゲーム機、携帯型音楽プレーヤ等のようなものであってもよい。
D制御部118からの指示に基づいて、3D映像として表示させるための各種信号処理を実行する。3D処理部120における各種信号処理には、例えば、3D伝送方式に応じた映像データの並び替え等がある。3D処理部120で信号処理が行われた映像信号は加算器134に送られる。
次に、受信機20の動作を、図16、図17のフローチャートに沿って説明する。コンテンツ再生が開始されると、受信機20(メタ情報処理部108)は、ステップS101において、メタ情報を取得して解析する。次に、受信機20(2D3D制御部118)は、その解析結果に基づき、コンテンツ全体が3Dであるか否かを判断する。
なお、上述していないが、図16、図17のフローチャートに示す一連の処理は、ハードウエアにより実行させることもできるし、ソフトウエアにより実行させることもできる。一連の処理をソフトウエアにより実行させる場合には、そのソフトウエアを構成するプログラムが、専用のハードウエアに組み込まれているコンピュータ、または、各種のプログラムをインストールすることで、各種の機能を実行することが可能な、例えば汎用のパーソナルコンピュータなどに、プログラム記録媒体からインストールされる。
