摘要： A data transmitting and receiving method for improving transmission and reception efficiency can be obtained by improving the security through update of a control key and reduction of the frequency of the authentication and key exchange process. An STB 1 transmits encrypted digital data Kw (D) obtained by encrypting digital data D using a work key Kw, and an encrypted work key Kc (Kw) obtained by encrypting the Kw using a control key Kc. The Kc is periodically or non-periodically updated, and an identifier L identifying the Kc is assigned to each Kc. A VTR device 2 decrypts the received Kc (Kw) using the Kc obtained by performing the authentication and key exchange process with the STB 1, decrypts the Kw (D) received using the Kw to obtain the D. It is determined whether or not the Kc has been updated while the reception process is suspended by referring to the transmitted L when the reception process is suspended and then resumed. If it is determined that the Kc has been updated, then the authentication and key exchange process is performed again to obtain the updated Kc.

摘要： It is objected to simplify a procedure concerning bandwidth acquisition. Bandwidth acquiring means 809 of a second transmitting apparatus 814 acquires a bandwidth which was used by a first transmitting apparatus 806 by using a propagation delay identifier 804 read from first transmitting apparatus 806 and a maximum transmission data size 805 after stopping transmission of first transmitting apparatus 806. Each apparatus is composed so that transmission is started using this bandwidth and because returning and re-acquisition are not accompanied when the transmission is switched, necessary procedure can be simplified. Further, it is possible to effectively use the bandwidth by using a propagation delay identifier.

摘要： In a digital signal recording and reproducing apparatus, digital input data is transmitted in a transmission packet format and is recorded in a recording packet format. In a recording stage, an auxiliary signal generator (3) generates an auxiliary signal for special reproduction in the transmission packet format, and the digital and auxiliary signals are converted into respective recording packets by means of recording signal converters (5, 6). Recording means (9, 10) performs a specific recording process on the recording packets and an identification signal for identifying between the recording packets of the digital signal and of the auxiliary signal. While in a reproducing stage, reproduction signal processing means (14, 15) performs a specific reproduction process on the reproduction signal to thereby reconstruct the recording packets and the identification signal. A packet selector (16) detects the reconstructed identification signal to determine whether the recording packet is of the digital signal or of the auxiliary signal, and then the digital signal or auxiliary signal is reconstructed by a signal reconstructor (17) in the transmission format using the selected recording packet, whereby a high quality image output conforming to the transmission format used in the normal reproductions mode is also obtained during the special reproduction modes.
