A display device includes: a video playback unit configured to play video media including multiple frames; a first memory unit configured to store a video signal of the video media that is being played; an acquisition unit configured to acquire a readout control signal representing a readout timing for playing each frame in the video media in a first display device different from an own display device in a multi-display system formed from multiple display devices; a readout control unit configured to cause frames of the video signal corresponding to the readout controls signal to be sequentially read out from the first memory unit in accordance with the acquired readout control signal; and a display control circuit configured to display, on a display unit, the frames of the video signal that have been read out.

Display device and multi-display system

A display system includes an arrangement of a plurality of display apparatuses. Each of the plurality of display apparatuses includes a display panel that displays an image, a processor configured to process the image for display, a memory storing the image information for processing by the processor to display on the display panel, and a send and receive hardware interface that at least receives setting information of one of the plurality of display apparatuses. A first display apparatus of the plurality of display apparatuses displaying an arrangement image, the first display apparatus further comprises a coordinate acquiring hardware that acquires a coordinate in the first display apparatus, the coordinate specifies a position of a second display apparatus of the plurality of display apparatuses displayed in the arrangement image, and a first send and receive hardware interface of the first display apparatus receives setting information of the second display apparatus.

Display system, display apparatus and adjustment method

An image display device having a display panel, the device being utilized to form an image display system in which a plurality of the image display devices are arrayed in one or both of vertical and horizontal directions to display one image as a whole while an image allocated to each device is displayed via the corresponding display panel, the image display device includes a reading processing unit that reads out image information and delays start of output of this image information by a predetermined period of time determined based on the number of the image display devices which forms the image display system and a row to which the present device belongs in the vertical arrangement.

Image display device, the image display system, and image display method

A display system includes a plurality of display apparatuses. Each of the plurality of display apparatuses includes a display panel that displays an image and a sending and receiving unit that at least receives setting information of one of the plurality of display apparatuses. A first display apparatus that is one of the plurality of display apparatuses further includes a coordinate acquiring unit that acquires a coordinate. A first sending and receiving unit of the first display apparatus receives setting information of a second display apparatus specified by the coordinate from the second display apparatus. A first display panel of the first display apparatus displays a setting image that indicates the setting information.

A moving image distribution server for distributing to a reproducing apparatus moving image data including video data and audio data and capable of prescribing decoding times and reproducing times for the video data and the audio data, the moving image distribution server including a data storage unit for storing in advance the moving image data including information as to the decoding times and the reproducing times for the video data and the audio data, a phase adjustment variable storage unit for storing a predetermined phase adjustment variable, and a first rewriter for reading the moving image data stored in the data storage unit, and changing the information included therein as to the decoding times or the reproducing times based on the predetermined phase adjustment variable to adjust the phase relationship between the video data and the audio data.

Moving image distribution system and moving image distribution server

Upon receipt of an MPEG stream, a time information converter modifies the PTSs of the audio data in the stream so that the timing for outputting the audio sound is delayed by the amount of time that is required for the processing of the video signal to be performed in a video signal processor while keeping the PTSs of the video data in the stream unchanged.

Video and audio reproducing apparatus and video and audio reproducing method for reproducing video images and sound based on video and audio streams

A moving image distribution system is capable of making phase adjustment of video data and audio data while preventing the cost of a display apparatus from increasing, by adjusting time information with a moving image distribution server. The moving image distribution server stores moving image data, reads the moving image data, changes information included therein as to decoding times or reproducing times of video data or audio data included in the moving image data based on a predetermined phase adjustment variable, and then distributes the moving image data. A reproducing apparatus receives the moving image data distributed from the moving image distribution server, decodes the moving image data according to the information included therein as to the decoding times and the reproducing times, and reproduces the moving image data.
