Abstract
Description
1.第1の実施形態(複数の任意の画像を伝送する例)
2.第2の実施形態(立体視画像への適用)
先ず、本実施形態に係るシステムの概念について、図面に基づいて説明する。ここではゴルフ中継のコンテンツを例に、付加情報動画像として二眼立体視には使用しない動画像を伝送する場合について説明する。尚、ゴルフ中継のコンテンツは単なる例示であり、本発明の適用範囲はゴルフ中継に限られるものではない。
本実施形態では、現行の動画像圧縮伸長手段からの変更を少なくするために、通常視聴用動画像と付加情報動画像を1フレーム(またはフィールド)上に配置して、1つの動画像(以後、統合動画像と記述する)として圧縮伸長処理を行う。
現行のデジタル放送システムで上記の統合動画像を伝送する場合を説明する。現行のデジタル放送システムでは、MPEG2-TS(transport stream)と呼ばれるパケット多重化方式により、動画像も音声も符号化されて伝送される。動画像のコーデックとしてはMPEG2
VIDEO、H.264(AVC)が主流を占めており、動画像はこれらのコーデックによって圧縮されて伝送される。
図22は、本実施形態に係る送信装置100を示すブロック図である。図22に示すように、送信装置100は、動画像圧縮部102、通常視聴用動画像領域符号化部104、付加情報動画像存在情報符号化部106を備える。図22の送信装置100への入力は、通常視聴用動画像と付加情報動画像を統合した統合動画像、通常視聴用動画像の統合動画像内での領域とアスペクト・レシオ、付加情報動画像の種類と(送信受信間であらかじめ取り決めがない場合の)領域、付加情報動画像使用時の通常視聴用動画像の統合動画像内での領域(送信受信間であらかじめ取り決めがない場合)であり、出力はこれらが符号化されたストリームである。なお、図23は、既存の送信装置を示しており、既存の送信装置は、符号化情報動画像存在情報符号化部106を備えていない点で図22の送信装置100と相違する。図22及び図23に示す構成は、回路などのハードウェア、又は中央仙山処理装置(CPU)とこれを機能させるためのプログラム(ソフトウェア)によって構成することができる。後述する受信装置についても同様である。
本実施形態では、図1のように配置された統合動画像を動画像圧縮部102にて既存のコーデックにて動画圧縮する。さらに、図2の配置情報のうち、通常視聴用動画像のサンプル・アスペクト・レシオならび領域を示す情報(左上端点、幅高さ)は、通常視聴用動画像領域符号化部104にて既存のコーデックの符号化方法を用いて符号化する。
左上端点の座標(xs,ys)は、
xs=SubWidthC * frame_crop_left_offset
ys=SubHeightC * (2-frame_mbs_only_flag) * frame_crop_top_offset
で示される。
xe=PicWidthInSamles
- (SubWidthC * frame_crop_right_offset + 1)
ye=16 * FrameHeightInMbs
- (SubHeightC * (2-frame_mbs_only_flag) * frame_crop_bottom_offset + 1)
で示される。
xs=2 * frame_crop_left_offset
ys=2 * frame_crop_top_offset
xe=PicWidthInSamles
- (2 * frame_crop_right_offset + 1)
ye=16 * FrameHeightInMbs
- (2 * frame_crop_bottom_offset + 1)

frame_crop_left_offset=0
frame_crop_top_offset=0
frame_crop_right_offset=480
frame_crop_bottom_offset=8
として設定すればよい。
図1の例では、通常視聴用動画像のほかに、付加情報動画像1,2の2つの付加情報動画像を伝送している。これらの付加情報動画像は、番組上の補足動画像として有効な動画像であるが、常に表示されるというよりは、ユーザの好みに応じて表示される動画像と考えてよい。
H.264規格には、Supplemental enhancement information(SEI)という、補助情報の記述方法がある。SEIではデコードの際の入出力バッファ内のデータの保持時間やランダムアクセス時にデコードを行うポイントの提示などの情報を記述する。
MPEG2-TSでは、伝送する番組プログラムの、ストリーム情報を記述するPSI(Program System Information)として、PMT(Program map table)がある。
MPEG2-TSでは、PMTの階層と同じ階層に、sectionデータを伝送することができる。このsectionに新規追加する場合を想定して、private sectionが考えられており、本実施形態の付加情報動画像存在情報を、新規のprivate sectionとして伝送することも考えられる。図8は、付加情報動画像存在情報を、新規のprivate sectionとして伝送する場合を示している。
VIDEO(ITU-T Rec.H.262)であっても同様である。
本実施形態の受信装置200では、付加情報動画像有りの番組プログラムを受信した場合には、ユーザから受信装置200への設定・指示によって、少なくとも以下の3通りの表示を選択することができる。
1)通常視聴用動画像を通常通りに表示すること
2)通常視聴用動画像と付加情報動画像を同時に画面表示すること、
3)付加情報動画像のみを画面表示すること
ここでは山の景色の複数眼立体視コンテンツを例に、付加情報動画像として複数眼立体視に使用する動画像を伝送する場合について、送信・受信間で、以下の情報についての取り決めを行った場合について説明する。尚、取り決めを行わない場合については「第1の実施の形態」と同様にこれらの情報を伝送すればよい。

・付加情報動画像の位置
・付加情報動画像の幅高さ
・付加情報動画像のサンプル・アスペクト・レシオ
ここでは複数眼立体視のうちの二眼立体視動画像に対して、左眼動画像を通常視聴用動画像、右眼動画像を付加情報動画像として伝送する場合を考える。
(1)通常視聴用動画像と付加情報動画像の画像サイズは同じ幅高さである。
(2)通常視聴用動画像と付加情報動画像のサンプル・アスペクト・レシオは同じである。
(3)付加情報動画像使用時の通常視聴用動画像の切り出し領域は付加情報動画像非使用時の通常視聴用動画像の切り出し領域と同じであること、
を取り決めることとする。
xa=frame_crop_left_offset
ya=16 * FrameHeightInMbs
- 2 * frame_crop_bottom_offset
となり、付加情報動画像の画像サイズ(w、h)は、通常視聴用動画像と同じで
w=PicWidthInSamles
- 2 * frame_crop_left_offset
- 2 * frame_crop_right_offset
h=16 * FrameHeightInMbs
- 2 * frame_crop_top_offset
- 2 * frame_crop_bottom_offset
となる。
xb=xa
yb=ya+(16 - ya%16)
となる。(ya%16はyaを16で除算した余りを示す。)
(4)付加情報動画像の統合動画像における切り出し開始位置の特定方法を、たとえば、図12のテーブルに基づき、テーブルに無い画像サイズの場合はその高さ以上で最も近い高さを持つものを使用するとする。
を取り決めることとする。
・付加情報動画像使用時の通常視聴用動画像の切り出し領域、
・付加情報動画像の位置
・付加情報動画像の幅高さ
・付加情報動画像のサンプル・アスペクト・レシオ
・H.264のSEI
(MPEG2 videoであればUSER_DATA)
・MPEG2-TSのPMTのdescriptor
(MPEG2-PSであればPSMのdescriptor)
・MPEG2-TSのprivate section
といった情報について、本実施形態を適用した場合を説明する。
VIDEO(ITU-T Rec.H.262)であっても同様である。
レンチキュラー方式やパララックスバリア方式では、複数眼立体視の動画像を扱うことが可能である。この場合、例えば第1及び第2の画像を左目用及び右眼用の画像として第1の方向から立体視が可能となり、第3及び第4の画像を左目用及び右眼用の画像として第1の方向と異なる第2の方向から立体視が可能となる。本実施形態は、動画像出力手段にこれらの方式の画像提示方法を持っている場合にも有効であり、通常視聴用動画像として、複数眼立体視のうちの1画像を用い、残りの画像については、付加情報動画像として扱えば良い。
この取り決めで並べた場合の統合画像の配置状況を図14に示す。図13、図14についても画像間に間隔をあけるかどうかも含めて取り決めを行う必要がある。もちろん、付加情報動画像の種類として、画像間隔あり横方向方向配置三眼立体視、画像間隔なし横方向三眼立体視の2種類を用意しておき、付加情報動画像存在情報として伝送すればコンテンツごとに、どちらの統合動画像の形式かを選択することができる。
さらに、番組プログラムとしては、第1の実施形態で記述したように、別の観点からの映像を伝送することも考えられる。メイン映像が立体視動画像であるので、別の観点からの映像も立体視動画像とした方が視聴上好ましいので、立体視動画像であるとして説明する。なお、特に別観点映像が立体視動画像でなくとも、本実施形態は有効である。
補足用の立体視動画像である、補足横配列三眼視用の付加情報動画像となる。補足横配列三眼視用は、横配列三眼視用で、かつ、通常視聴用動画像を含まないことを意味しており、単なる横配列三眼視用とは異なることを意味するものとする。
・通常視聴用動画像を用いるかどうかのビット

・送信側と受信側で付加情報動画像の位置を取り決めたかどうかのビット、
・送信側と受信側で付加情報動画像の幅高さを取り決めたかどうかのビット、
・送信側と受信側で付加情報動画像のサンプル・アスペクト・レシオを取り決めたかどうかのビット、
・立体視かどうかのビット
・立体視の場合に横並びかどうかを示すビット

・メインの付加情報動画像の位置
・メインの付加情報動画像の幅高さ
・メインの付加情報動画像のサンプル・アスペクト・レシオ
を特定し、次に、補足横配列三眼視用の付加情報動画像を指定することで、三眼分の付加情報動画像の、位置・幅高さ・サンプル・アスペクト・レシオを特定することができる。
既定横配列三眼視用の付加情報動画像を指定することで、以下の情報を特定する。
・メインの付加情報動画像使用時の通常視聴用動画像の切り出し領域、
・メインの付加情報動画像の位置
・メインの付加情報動画像の幅高さ
・メインの付加情報動画像のサンプル・アスペクト・レシオ
図31は、通常視聴用動画像を左眼動画像1440x1080、付加情報動画像を右眼動画像480x1080として統合画像内に配置した場合であり、図32は、通常視聴用動画像を中央動画像1920x810、付加情報動画像を960x270の2画像(左動画像、右動画像)として配置した場合である。
