摘要： An image switching device for connecting a plurality of image outputting devices via a digital interface and capable of selecting image outputs sequentially, and image outputting devices. Cameras (101 to 104) are connected to a camera switching device (105) via an IEEE 1394 standard-based digital interface (114). Synchronizing timing signals transmitted in isochronous communication packets from the camera switching device (105) are synchronized with image signals on the camera (101 to 104) sides, each camera (101 to 104) transmits its image signals in synchronous communication packets based on image switching control data transmitted in asynchronous communication packets or isochronous communication packets from a camera switching control unit (106), and the camera switching device (105) selectively receives image data transmitted from a desired camera based on image switching control data.

摘要： A system and method for creating multimedia information synchronized with a video signal ( e.g., a program of a television broadcast) are provided. The multimedia information may be formatted in accordance with, for example, the MHEG standard or the ATVEF standard. The system includes means for specifying and verifying the contents of, and synchronizations for, the multimedia information. A scenario creation program creates a scenario composed of a plurality of scenes synchronized with playback of the video. A scene creation program combines objects consisting of text, images, audio, operation buttons and the like to create scenes (pages). A contents management program, a scenario management program and a scene management program set a directory of the contents, the scenarios and the scenes.

摘要： A method and a system are disclosed for synchronizing audio/video data with interactive applications in an interactive TV system. A trigger event data packet, such as the "Do It Now" command, is inserted into the video frame data packet stream at a location that is correlated to a data packet representing a specified video frame. Thus, a robust and effective synchronization mechanism is provided that also offers a high degree of compatibility with currently available equipment.

摘要： Signal (digital sine wave signals) (Sd) stored in a memory means (3) are read. The phase of input signal (analog sine wave signal) (Sr) supplied to an input terminal is compared with that of signal (Sa) generated by D/A-converting the signals (Sd) (by means of a comparator (2)), the reading address signal of the memory means (3) is controlled based on the phase error signal (a) generated as a result of the comparison by the comparator (2) (by means of an address forming circuit (5)). Thus, the phase of the digital sine wave signals (Sd) supplied to an output terminal (6) is synchronized with that of the analog sine wave signals (Sr) supplied to the input terminal (1). Desired digital signals synchronized with the phase of the input signals can be generated by processing the digital signals with a simple constitution.

摘要： A superimposing circuit (10̸) includes a PAL ID circuit (50̸) in which phases of an external burst signal and a CDG burst signal are compared with each other. If the phases are not coincident with each other, it is determined that polarities of the burst signals are not coincident with each other, and therefore, the PAL ID circuit (50̸) outputs a PAL ID signal to a color encoder (28). In response to the PAL ID signal, the color encoder (28) stops a changeover of the polarity at every 2H such that the polarities of the both burst signals can be made to be coincident with each other.

摘要： A time-axis of a digital video-signal is converted to a standard time-axis by changing a clock signal contained therein to a standard clock signal and by locking phases of input synchronizing signals contained therein onto the phase of the standard clock signal through a memory for alternately writing and reading the digital video signal at one half of the period of the standard clock signal. As a result, the time-axis correction of the digital video signal is efficiently effected through the memory having a small capacity and a simplified controlling arrangement.
