摘要： 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.

摘要： Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's user station where selected music files are recorded. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to playback for their enjoyment. An antipiracy WID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction. Music is transmitted on a fixed schedule or through an active scheduling process that monitors music requests from all or a subset of satellite receivers and adjust scheduling according to demand for various CD's. Receivers store selections that are likely to be preferred by a specific customer. In those instances where weather conditions, motion of atmospheric layers or dish obstructions result in data loss, the system downloads the next transmission of the requested CD and uses both transmissions to produce a “good copy”. In conjunction 20 with the blanket transmission of more popular music, an automated CD manufacturing facility may be provided to manufacture CD's that are not frequently requested and distribute them by ground transportation.

摘要： A control device and control method are suitable for copying digital data between electronic devices connected to one another via a digital data bus. A digital broadcast receiver receives and decodes a digital broadcast signal, and outputs the resulting video signal to a display and the resulting audio signal to a speaker. The digital broadcast receiver also exchanges decoded video signals and audio signals with digital recorders/players that are connected to one another via an IEEE 1394 data bus. Further, the digital broadcast receiver controls a digital data copy operation that is performed among the digital recorders/players connected to the IEEE 1394 data bus.

摘要： An apparatus, method and a computer program for processing multimedia data is described, where the apparatus may include an input switch which may receive a plurality of transport stream packets corresponding to a plurality of digital multimedia data signals input thereto, and a packet identification (PID) filter unit which may selectively output a given set of TS packets to be demultiplexed from the received plurality of TS packets. A buffer and/or an external memory device may store at least some of the TS packets of the output given set. A conditional access/content protection (CA/CP) unit may read and decrypt the TS packets stored in the buffer, and may encrypt at least some of the decrypted TS packets for storage in the external memory device if the buffer becomes full, to prevent the TS packets to be stored in the external memory device from being copied.
