On a reception side, display processing and the like is easily performed in synchronization with content data. A cam coder transmits reproduction content data to a television set through a TMDS line of an HDMI cable. The cam coder transmits processing information used to perform the display processing in synchronization with the reproduction content data to the television set through a bidirectional communication path included in the cable before the reproduction content data is transmitted. Index information is added to the processing information for each unit of processing. Index information corresponding to the index information added to the processing information is added to the reproduction content data at a timing when the processing information of each unit of processing is processed. The television set superposes information on a shooting location, a date and time, and the like on an image in accordance with the processing information corresponding to the index information at a timing when the index information is added to the received content data.

Transmission apparatus, information transmission method, reception apparatus, and information processing method

A storage device incorporating an electrically erasable read only memory (EEPROM) or other data storage device having a limited number of total times of rewriting, has its useful like extended by the method of storing a pointer corresponding to the capacity of the memory, which pointer identifies a start position in the data storage device at which rewriting is to occur, and incrementing the pointer sequentially with each writing of the data storage device. The method and associated apparatus may be used to maintain a record of on-time of electronic apparatus, and/or to maintain data for correcting the white balance of a video camera under various light conditions.

A video signal recording and/or reproducing apparatus includes a copy guard processing detecting current which can correctly judge whether or not a copy guard is applied to an input video signal and prevents copy guard processing from being applied to a video signal to which a copy guard is not applied. The copy guard processing detecting apparatus includes a first circuit for receiving an input video signal which includes a plurality of false synchronizing signals for prevention of duplication inserted in a vertical blanking interval thereof and for counting the number of the false synchronizing signals, a second circuit for counting the number of synchronizing signals in an image interval of the input video signal except the vertical blanking interval, a discriminating circuit for discriminating whether or not copy guard processing is applied to the input video signal from the count values of the first and second circuits, and a recording system for receiving and recording the input video signal based on the results of the copy guard discriminating operation.

A double-deck video tape recorder has two tape cassette slots defined in a front panel thereof for inserting and ejecting respective magnetic tape cassettes therethrough. The double-deck video tape recorder also has a pair of drive mechanisms disposed in a housing for recording information on and reproducing information from the magnetic tape cassettes inserted in the respective drive mechanisms through the tape cassette slots. When an edit direction key is pressed, a control system places one of the drive mechanisms in a playback mode and another of the drive mechanisms in a recording mode. When a start/pause key is pressed, the control system starts to operate the one of the drive mechanisms to reproduce recorded information from the magnetic tape cassette inserted therein and also to operate the other drive mechanism to record the reproduced information in the magnetic tape cassette inserted therein.

Copy guard processing detecting apparatus

According to the present invention, in an image enhancer, an output of an outline extracting circuit is transmitted through a band limiting filter for suppressing bands other than an objective frequency band to be enhanced and, thereafter, it is supplied to a noise slicing circuit for eliminating micro amplitude noises. The noises near the cut-off frequency of the filter can be more effectively suppressed and the deterioration of the waveform characteristic of the outline enhancement signal due to the filter can be also improved.
