A content access method and apparatus includes decompressing an input stream read from a storage medium to produce an output signal. The output signal is then multiplexed with timing information different from the timing information contained in the input stream.

Digital information processing method

Method and apparatus for digital information processing

In a DVD video player with a built-in CD-R drive, until it reaches the state that the data of an optical disk can be reproduced, the output is switched into the reproduction output from a flash memory, a record medium that is quick to start reading. This makes it possible to develop user interfaces such as: voluntarily reproducing an audio information from the flash memory to add music sounds or sounds with special effects to the screen saver, in replacement of the optical disk drive that cannot read data during the screen saver being in operation or being in standby; reproducing the sounds with special effects; reproducing click sounds in response to a key input from the key or the remote control unit; and announcing to inform of the state to the user.

Recording/reproducing method and device with supplementary data storage and output

A communication system has an analog signal broadcasting station for transmitting an analog signal, a digital signal broadcasting station for transmitting a digital signal and a receiving unit for receiving the analog signal from the analog signal broadcasting station and the digital signal from the digital signal broadcasting station. The receiving unit has a recording and reproducing unit for selectively recording one of received analog and digital signals. The recording and reproducing unit has heads for analog signal each having a predetermined azimuth angle and operative to record an analog signal and heads for digital signal each having an azimuth angle larger than that of the analog signal head and operative to record a digital signal, and performs selective recording and reproduction of the analog signal and the digital signal on and from a recording medium.

Communication system for encrypted data and apparatus for selectively recording and reproducing received analog signal and received digital signal

A billing system for use in a chargeable program broadcasting is capable of reliably billing a subscriber for program reception while preventing unauthorized reception thereof. A receiving terminal includes a primary terminal,and a secondary terminal,. The primary terminal,receives a compressed video signal and confirms by an error checker,thereof whether there is a transmission error and bills, by a billing device,thereof, the receiving subscriber on the basis of an error information and a program information, etc., separated from the video signal by a separation circuit,. The compressed video data is time-axis multiplexed with a terminal identifying code and a key signal and transmitted to the secondary terminal,. In the secondary terminal,, a bill for the subscriber is confirmed by the terminal identifying code and the compressed data is decoded by a decoder circuit,thereof.

Interactive chargeable communication system with billing system therefor

A billing system for use in a chargeable program broadcasting is capable of reliably billing a subscriber for program reception while preventing unauthorized reception thereof. A receiving terminal includes a primary terminal 100 and a secondary terminal 150. The primary terminal 100 receives a compressed video signal and confirms by an error checker 113 thereof whether there is a transmission error and bills, by means of a billing device 114 thereof, the receiving subscriber on the basis of an error information and a program information, etc., separated from the video signal by a separation circuit 112. The compressed video data is time-axis multiplexed with a terminal identifying code and a key signal and transmitted to the secondary terminal 150. In the secondary terminal 150, a bill for the subscriber is confirmed by the terminal identifying code and the compressed data is decoded by a decoder circuit 166 thereof.
