Abstract
【課題】一枚の１２センチビデオディスクに、記録フォーマットの異なる二種類の信号を記録させる販売・レンタル用ビデオディスクを提供する。【解決手段】記録層が片面一層の１２センチ・デジタル・ディスクで、収録時間がだいたい同じぐらいになるように記録面を内周と外周で分けて、ＤＶＤ方式とブルーレイ方式のそれぞれ異なる信号フォーマットで同一コンテンツをハイブリッド収録する。また、記録層が片面二層または両面二層の１２センチ・デジタル・ビデオディスクで、収録時間がだいたい同じぐらいになるように記録面を内周と外周で分けて、ＤＶＤ方式とブルーレイ方式のそれぞれ異なる信号フォーマットで同一コンテンツをハイブリッド収録する。【選択図】図１PROBLEM TO BE SOLVED: To provide a video disc for sale / rental in which two types of signals having different recording formats are recorded on one 12 cm video disc. SOLUTION: A 12 cm digital disc having a single-sided recording layer, the recording surface is divided into an inner circumference and an outer circumference so that the recording time is about the same, and different signal formats of a DVD system and a Blu-ray system are used. Hybrid recording of the same content. In addition, the recording layer is a single-sided double-layer or double-sided double-layer 12 cm digital video disc, and the recording surface is divided into the inner circumference and the outer circumference so that the recording time is about the same, and the DVD system and the Blu-ray system are used respectively. Hybrid recording of the same content in different signal formats. [Selection diagram] Fig. 1
Description
本考案は、一枚の１２センチビデオディスクに、記録フォーマットの異なる二種類の信号を記録させるものです。 This invention is to record two kinds of signals with different recording formats on one 12cm video disc.
現在、デジタル・ビデオディスクにはＤＶＤ方式とブルーレイ方式の二種類あり、同一タイトルのソフトがわざわざ二種類発売されています。 Currently, there are two types of digital video discs, DVD and Blu-ray, and two types of software with the same title are on sale.
同一タイトルを二種類発売するのは、メーカーにとっても製造・流通コストが二重にかかるし、小売店も陳列スペースをとるし、消費者も店に欲しい商品がなかったりと、不都合を生じさせています。これを一枚のディスクにまとめたい。 Launching two types of the same title causes inconveniences for manufacturers, including double manufacturing and distribution costs, retail stores taking up display space, and consumers not having the products they want. The I want to put this on a single disc.
ＤＶＤは一層の記録容量が４．７Ｇバイトで、映像記録時間に換算して約１２０分前後。ブルーレイは２５Ｇバイトで容量に余裕がある。それを少し間引いて記録面をＤＶＤに割り当ててやれば、一枚のディスクにＤＶＤ方式とブルーレイ方式両方の信号フォーマットで同一コンテンツをハイブリッド収録することができると思います。
片面一層ディスクの内周と外周で記録方式を分ければ、同一コンテンツをだいたい８０分前後ずつ、二層にすれば１６０分前後ずつハイブリッド収録できるのでは？
単純に片面二層ディスクの一層目と二層目で記録方式を分けても、だいたい１２０分前後までなら収録できると思います（収録時間は作品の情報量にもよりますが）。DVD has a single-layer recording capacity of 4.7 Gbytes, which is about 120 minutes in terms of video recording time. Blu-ray has a capacity of 25GB. If you thin it out and assign the recording surface to DVD, you can record the same content on a single disc in both DVD format and Blu-ray format.
If the recording method is divided into the inner and outer peripheries of a single-sided single-sided disc, the same content can be hybrid-recorded approximately every 80 minutes, and if double-layered, it can be recorded in approximately 160 minutes.
Even if the recording method is simply divided into the first and second layers of a single-sided dual-layer disc, it can be recorded up to about 120 minutes (although the recording time depends on the amount of information in the work).
もし実現すれば、製造・流通コストの削減、消費者の利便性向上は明らかです。
ブルーレイ方式のレコーダー、プレーヤーは普及率が低いので、一枚のディスクでＤＶＤとブルーレイの双方に互換性を持たせる意味は大きいと思います。８０分以下の短編ソフトさえ、わざわざ二種類出してる現状は資源と労力の無駄使いです。If realized, the reduction of manufacturing and distribution costs and the improvement of consumer convenience are clear.
Blu-ray recorders and players have a low penetration rate, so I think it's important to make both DVD and Blu-ray compatible with a single disc. Even the short software of less than 80 minutes is bothering resources and labor.
