Description
別の表現をすると、映画等の著作権を持つ側の利益と、映画等の映像情報をいつでもどこでも楽しみたい一般の消費者の利益が相反する現状に対し、両者に利益をもたらす新しい仕組み(ユビキタスムービー)を追加創造することが課題といえる。
図1は、映像情報記録済み光ディスク媒体の一実施例の構成例を示したものである。1は光ディスク媒体、2は第1の映像情報の記録エリア、3は第2の映像情報の記録エリアである。
図3ではフラッシュメモリカード12、HDD13は再生モード、光ディスク装置5は記録モードになっており、直径8cmの記録可能な光ディスク媒体23が光ディスク装置5に装着されており、フラッシュメモリカード12あるいはHDD13から再生され、信号選択回路24で選択出力された第2のデジタルデータ25は書き込み装置26を経て小型光ディスク媒体23に記録される。
図4において、27は小型ディスプレイ付き映像情報の再生装置、28は8cm光ディスク媒体23の再生装置、29は第1及び第2の映像情報を再生する信号処理回路、30は小型ディスプレイ、31は著作権保護情報及びVeil情報や電子透かし情報の著作権保護情報読出し回路、32はVeil情報や電子透かし情報を含む映像情報、33はビデオ信号制御信号、34はビデオ信号出力端子、35は音声信号出力端子である。
小型の光ディスク媒体としては、図3で作成したような低画質映像情報である第2の映像情報を記録した光ディスク媒体だけでなく、図1の実施例において前述したような高画質映像情報である第1の映像情報と第2の映像情報を同一媒体上に記録済みであるプリレコーデッドの8cm光ディスク媒体、及び現在市販されている高画質情報のプリレコーデッドの8cm光ディスク媒体がある。小型ディスプレイ付き再生装置27はこれらの8cm光ディスク媒体を再生することが出来る。
映像信号にVeil情報や電子透かし情報が含まれる場合は、著作権保護情報読出し回路31で映像情報32に含まれる著作権保護情報及びVeil情報や電子透かし情報を読み出し、著作権保護情報がVeil情報あるいは電子透かし情報と一致しない場合はビデオ信号制御信号33により信号処理回路29を制御し、小型ディスプレイ30へのビデオ信号の供給を停止する。
図4に示す本発明の小型ディスプレイ付き映像情報の再生装置27は、持ち運びが容易な小型ディスプレイ付き映像情報の再生装置であり、高画質の第1の映像情報を見たい場合には、屋外で楽しむだけでなく屋内の大型のディスプレイに接続することが可能である。
出力端子としては、ビデオ信号出力端子34、音声信号出力端子35の代わりに上記したデジタル信号出力端子を設けても良いし、またはデジタル信号出力端子を追加しても良い。
Claims (2)
- 同じ映像情報に基づいて生成された所定の解像度の第1の圧縮映像情報及び前記所定の解像度に比して低解像度の第2の圧縮映像情報を記録媒体上に記録する記録方法であって、
前記映像情報を、第1の画像圧縮方法により所定の解像度で圧縮し、第1の暗号化方法により暗号化し、第1の著作権保護情報を付加した第1の圧縮映像情報と、
前記映像情報を、解像度の低い映像情報に変換し、前記第1の画像圧縮方法とは異なる第2の画像圧縮方法により、前記第1の圧縮映像情報に比して低解像度かつ高圧縮率で圧縮し、前記第1の暗号化方法とは異なる第2の暗号化方法により暗号化し、前記第1の著作権保護情報よりも制限度の低い第2の著作権保護情報を付加した第2の圧縮映像情報とを生成し、
前記第1の著作権保護情報が付加された第1の圧縮映像情報及び前記第2の著作権保護情報が付加された第2の圧縮映像情報とを前記記録媒体上に記録することを特徴とする記録方法。 - 前記第2の圧縮映像情報は前記映像情報を再生時間が短くなるように編集した情報を圧縮した圧縮映像情報であることを特徴とする請求項1に記載の記録方法。
