摘要： In order to limit use of content, when a source receives a request for transmitting content from a sink, the source performs an authentication process. When the authentication is successful, the source transmits to the sink key information necessary for decrypting the encryption applied to the content. The sink can receive the content by receiving the key information and by decrypting the encryption applied to the content by using the key information.

摘要： The present invention relates to a telecommunications apparatus and a method, a storage medium, and a program for determining whether or not the other side communicating content data is located on a LAN or across a WAN. In step S13, the difference between a counter value in a received check packet and a value in a register is computed. In step S14, the resultant difference is checked to determine if it is equal to a constant value X. If it is determined that the difference is equal to the constant value X, the counter value in the packet is stored in the register in step S15. In step S16, it is determined whether or not all the predetermined number of check packets is received. If all the predetermined number of check packets is received, it is determined that the communication takes place over a LAN connection in step S17. If, in step S14, it is determined that the difference is not equal to the constant value X, it is determined that the communication takes place across a WAN connection in step S18. The present invention can be applied to a personal computer on a wireless LAN.

摘要： In a digital broadcast receiving apparatus, digital broadcast signals provided by a digital broadcast method are supplied to various types of external units and are effectively utilized. In the above apparatus, a descrambler descrambles a transport stream output from a front end unit and supplies it to a digital interface and a demultiplexer. The demultiplexer extracts from the transport stream a compressed video signal and a compressed audio signal of a program specified by a user, and supplies the extracted signals to an MPEG decoder. The MPEG decoder decompresses the supplied video signal and the audio signal and supplies them to the digital interface, an NTSC encoder, and an audio signal D/A converter. The digital interface supplies either of the transport stream or the decompressed data to a digital external unit under the control of the controller.

摘要： A transmitting apparatus and method, and a receiving apparatus and method for communicating a pack of 2,048 bytes using the digital interface in accordance with the IEEE 1394 standard. A 4-byte time stamp is added to a 2,048-byte pack of MPEG (Moving Picture Experts Group)-PS (program stream) data. Also, 124 bytes of padding data is added to this pack in order that the overall byte length of data be a multiple of 16. Then the data is divided into a number of fractions which is a multiple of 2 (e.g., 32), thereby being converted into a number of data blocks equal to the number of fractions. Each data block has a byte length of a multiple of 4 (e.g., 68 bytes). A CIP header and the like are added to a predetermined number of the data blocks to form a packet.

摘要： To securely transmit content through remote access via an external network, such as a WAN, while exceeding restrictions of an RTT and a TTL.A way of handling a flag for controlling remote access of content is explicitly defined, and an authentication method is explicitly defined when a content using device performs remote access. Thus, also in remote access, similarly to access of the related art in a household, a copyright protection environment of content based on the DTCP-IP is constructed.
