Description

本発明は、コンテンツの保護方法に関する。 The present invention relates to a content protection method .

Claims (1)

放送局側から放送番組のコンテンツを伝送し、受信装置で前記コンテンツを受信する伝送システムの前記受信装置におけるコンテンツの保護方法であって、
前記伝送システムは、ＤＴＣＰ２のＬ２−Ｏｎｌｙフラグに対応する制御情報、ＤＴＣＰ２のＥＩフラグに対応する制御情報、ＤＴＣＰ２のＨＤＲフラグに対応する制御情報、ＤＴＣＰ２のＳＤＯフラグに対応する制御情報のいずれも放送局側から受信装置へ伝送しないものであり、
前記受信装置が前記放送局側から前記放送番組の前記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について、前記受信装置が有する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出力ステップと、を備え、
前記伝送システムにおいて、前記受信装置は、ＤＴＣＰ２のＬ２−Ｏｎｌｙフラグに対応する制御情報、ＤＴＣＰ２のＥＩフラグに対応する制御情報、ＤＴＣＰ２のＨＤＲフラグに対応する制御情報、ＤＴＣＰ２のＳＤＯフラグに対応する制御情報のいずれも取得しない受信装置であり、
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について、ＤＴＣＰ２の制御情報であるそれぞれ１ビットのＬ２−Ｏｎｌｙフラグ、ＥＩフラグ、ＨＤＲフラグ、ＳＤＯフラグを設定して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、Ｌ２−Ｏｎｌｙフラグは０に固定され、ＨＤＲフラグは０に固定される、ことを特徴とする、コンテンツの保護方法。 A method of protecting content in the receiving device of a transmission system, wherein the content of a broadcast program is transmitted from a broadcasting station side, and the content is received by the receiving device .
The transmission system broadcasts control information corresponding to the L2-Only flag of DTCP2, control information corresponding to the EI flag of DTCP2, control information corresponding to the HDR flag of DTCP2, and control information corresponding to the SDO flag of DTCP2. It is not transmitted from the station side to the receiving device,
A receiving step in which the receiving device receives the content of the broadcast program from the broadcast station side;
A storing step of storing the content received in the receiving step,
An output step of outputting the content stored in the storage step by protecting the content with DTCP2 through an interface of the receiving device and outputting the content.
In the transmission system, the receiving device controls the control information corresponding to the L2-Only flag of DTCP2, the control information corresponding to the EI flag of DTCP2, the control information corresponding to the HDR flag of DTCP2, and the control corresponding to the SDO flag of DTCP2. A receiving device that does not acquire any of the information,
In the output step, with respect to the content stored in the storage step, a 1-bit L2-Only flag, an EI flag, an HDR flag, and an SDO flag, which are control information of DTCP2, are set, and the content by DTCP2 is set via the interface. When protecting and outputting, the L2-Only flag is fixed to 0, and the HDR flag is fixed to 0, The content protection method characterized by the above-mentioned.
