Description

本発明は、コンテンツの出力方法に関する。 The present invention relates to a content output method .

Claims (1)

デジタル放送のコンテンツを受信してインタフェースから出力する放送受信装置におけるコンテンツの出力方法であって、
前記デジタル放送のコンテンツを受信する受信ステップと、
前記受信ステップで受信したコンテンツを蓄積する蓄積ステップと、
前記蓄積ステップで蓄積したコンテンツをインタフェースから出力する出力ステップと、
を備え、
前記受信ステップで受信した前記コンテンツにはＤＴＣＰ２のＬ２―Ｏｎｌｙフラグに対応する制御情報が設けられておらず、該コンテンツの解像度が水平１９２０画素×垂直１０８０画素以下であり、当該コンテンツを解像度変換せずに、前記出力ステップで前記蓄積ステップで蓄積したコンテンツを出力する場合の出力状態には、前記コンテンツを前記インタフェースを介してＤＴＣＰ２によるコンテンツの保護を行って出力する状態と、前記コンテンツを前記インタフェースを介してＤＴＣＰ１によるコンテンツの保護を行って出力する状態とがあり、
前記コンテンツを前記インタフェースを介してＤＴＣＰ２によるコンテンツの保護を行って出力する状態では、前記受信ステップで前記コンテンツを受信したときに、前記コンテンツが前記デジタル放送において1世代のみコピー可の保護が指定されて伝送されたコンテンツであっても、前記コンテンツが前記デジタル放送において個数制限コピー可の保護が指定されて伝送されたコンテンツであっても、前記コンテンツが前記デジタル放送において制約条件なしにコピー可の状態で伝送されたコンテンツであっても、前記蓄積ステップで蓄積したコンテンツを前記インタフェースを介してＤＴＣＰ２によるコンテンツの保護を行って出力するときにＤＴＣＰ２のＬ２―Ｏｎｌｙフラグを０に固定して出力する、
コンテンツの出力方法。 A content output method in a broadcast receiving device that receives digital broadcast content and outputs the content from an interface,
A receiving step of receiving the digital broadcast content;
An accumulating step of accumulating the content received in the receiving step;
An output step of outputting the content accumulated in the accumulation step from an interface;
With
The content received in the receiving step does not have control information corresponding to the L2-Only flag of DTCP2, and the resolution of the content is 1920 horizontal pixels × 1080 vertical pixels or less. Instead, when the content stored in the storage step is output in the output step, the output state includes a state in which the content is protected by DTCP2 via the interface and output, and a state in which the content is output through the interface. And the content is protected by DTCP1 and output.
In a state where the content is protected by DTCP2 and output via the interface, when the content is received in the receiving step, protection that the content can be copied for only one generation in the digital broadcast is designated. Even if the content is transmitted by the digital broadcast, even if the content is the content transmitted with the number-limited copy permitted protection specified in the digital broadcast, the content can be copied without restriction in the digital broadcast. Even if the content is transmitted in a state, when the content stored in the storing step is output with the content protected by DTCP2 via the interface, the L2-Only flag of DTCP2 is fixed to 0 and output. ,
Content output method.
