Abstract: To enable copy control according to original copy control information at a data output destination by converting copy control information defined in MMT format data into copy control information defined by DTCP and transmitting the converted copy control information to a network-connected device. The copy control information defined in the MMT format data is converted into the copy control information defined by DTCP and transmitted to the network-connected device. In the case where the transmission data is any of a 4K image, an 8K image, or an HDR image, and in a case where the copy control information defined by DTCP2 and the transmission data are images are 2K images or SDR images, the copy control information defined by DTCP1 is generated and recorded in a control information storage packet or a program map table (PMT) to be transmitted to a network-connected device, and transmitted.

Abstract: Captured images acquired by a plurality of imaging units are output to a captured image combining unit, which generates a composite image by joining the captured images in accordance with composite setting information generated by a composite setting information generation unit. A specific region information generation unit generates specific region information indicating the specific region corresponding to a specific imaging region in the composite image.

Abstract: The disclosure is directed to reduce a load of time and cost at the time of transition to a safer system in which an encryption scheme is newly set. By allowing a device of a transition step which implements a predetermined security reinforcement measure to handle high-value content only for a given system transition period, a problem of a time necessary for the transition can be avoided and the transition to the safer system can be performed smoothly. The device mentioned herein which implements the predetermined security reinforcement measure is, for example, a device which supports only an existing encryption algorithm and for which security of a weaker portion other than the encryption scheme is ensured.

Abstract: Content is transmitted within a range of the user's legitimate use while limiting the number of equipment to which the content is transmitted at the same time. A content using apparatus periodically transmits an exchange key and the corresponding key ID using a command. Only while receiving the key ID at predetermined reception cycles, a content providing apparatus maintains the corresponding exchange key. When not periodically receiving the key ID, the content providing apparatus destroys the corresponding exchange key. After that, when receiving a command including the key ID, the content providing apparatus returns a response including information indicating that the exchange key has become invalid.

Abstract: A communication apparatus includes a tuner, a content storage, and a controller that acquires content from the tuner, for one of providing the content to a terminal or recording the content to the content storage, and registers the terminal, in association with a registration date, to a home network. The terminal requests the content from outside the home network. The controller provides the content to the registered terminal based on a request, from the registered terminal, for the content, where the providing of the content to the registered terminal is based on the request, before an expiration date, for the content. The expiration date is based on the registration date of the registered terminal. The providing of the content to the registered terminal is restricted based on the request, after the expiration date, for the content.

Abstract: A source apparatus and a conditional access apparatus are disclosed. The source apparatus may transmit a command to the conditional access apparatus.
