Title: Method of protecting content
Inventor: SHIMIZU TAKUYA
IPC: H04N21/8355
Filed: 2020-06-10
Abstract: To provide a digital broadcast receiving apparatus capable of executing a function with a higher added value.SOLUTION: There is provided a broadcast receiving apparatus 100 to receive content transmitted through broadcasting signals. The broadcasting signals can transmit control information indicating a copy control state of transmitted content, control information for specifying whether protection is required when the transmitted content is output from the broadcast receiving apparatus, information indicating resolution of video of the transmitted content, and information indicating transmission characteristics of the video of the transmitted content. The control information for specifying whether protection is required indicates that protection is required or that protection is not required. When the control information cannot be received, a control unit determines that the control information indicates that protection is not required. The control unit executes control to apply output protection to the content in a case where the control information indicating the copy control state indicates that there is copy restriction or in a case where the control information indicates that protection is required on output.SELECTED DRAWING: Figure 7A
