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)
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、および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、
前記放送番組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前記受信装置が有する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、および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、
前記受信ステップにおいて受信した前記コンテンツがいずれの解像度であっても、前記伝送システムにおける前記コンテンツのコピー制御状態がいずれの状態であっても、前記コンテンツを解像度変換せずにそのまま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前記出力ステップで出力するときはDTCP2のL2−Onlyフラグの1ビットが示す値を0に固定して出力するものであり、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前記出力ステップで出力するときのDTCP2のL2−Onlyフラグの1ビットが示す値、DTCP2のEIフラグの1ビットが示す値、DTCP2のHDRフラグの1ビットが示す値、およびDTCP2のSDOフラグの1ビットが示す値の組み合わせは16よりも少ないものであり、
前記受信ステップにおいて受信した前記コンテンツの前記伝送システムにおけるコピー制御状態が制限なしコピー可であって出力時の暗号化による保護が指定されている場合は、前記出力ステップで、前記コンテンツを前記インタフェースを介してDTCP2による保護を行って出力する場合でもDTCP1による保護を行って出力する場合でも、EPN状態とし暗号化による保護を行って出力するものであり、
前記受信ステップにおいて受信した前記コンテンツを解像度変換せずに前記インタフェースを介して出力する出力状態には、BT.709規格に準拠した伝達特性を有するコンテンツを前記受信ステップで受信して、前記インタフェースを介してDTCP1による保護を行ってDTCP2のHDRフラグに対応するフラグ無しで出力する第1の出力状態と、BT.709規格に準拠した伝達特性を有するコンテンツを前記受信ステップで受信して前記インタフェースを介してDTCP2による保護を行ってDTCP2のHDRフラグの1ビットが示す値を0として出力する第2の出力状態とがある、
コンテンツの出力方法。 A method of outputting 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 includes any of 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 broadcasting station to the receiving device,
A receiving step of receiving the content of the broadcast program ,
An output step of outputting the content received in the receiving step from an interface of the receiving device ;
Equipped with
In the transmission system, the receiving device corresponds to 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 SDO flag of DTCP2. A receiving device that does not acquire any of the control information,
Regardless of the resolution of the content received in the receiving step or the copy control status of the content in the transmission system, the content is directly subjected to resolution conversion through the interface without resolution conversion. When the content is protected by DTCP2 and is output in the output step, the value indicated by 1 bit of the L2-Only flag of DTCP2 is fixed to 0 and output, and the content is protected by DTCP2 via the interface. And a value indicated by 1 bit of the L2-Only flag of DTCP2, a value indicated by 1 bit of the EI flag of DTCP2, a value indicated by 1 bit of the HDR flag of DTCP2, and an SDO of DTCP2. The combination of values indicated by 1 bit of the flag is less than 16,
When the copy control state of the content received in the receiving step in the transmission system is copy-enabled without restriction and the protection by encryption at the time of output is designated, the content is transferred to the interface in the output step. Whether the data is protected and output by DTCP2 or the data is protected and output by DTCP1, the EPN state is set, the data is protected by encryption, and the data is output.
The output state in which the content received in the receiving step is output via the interface without resolution conversion is BT. A first output state in which a content having a transfer characteristic conforming to the G.709 standard is received in the receiving step, is protected by DTCP1 through the interface, and is output without a flag corresponding to the HDR flag of DTCP2; . A second output state in which a content having a transfer characteristic conforming to the G.709 standard is received in the receiving step, protected by DTCP2 via the interface, and a value indicated by 1 bit of an HDR flag of DTCP2 is output as 0; There is
How to output the content.
