An encoding system includes: a plurality of encoding devices that each include an encoding processing unit configured to, at a timing in accordance with a vertical synchronization signal included in a moving picture signal, encode divided image data, wherein one encoding device acts as a single master and the remaining one or more encoding devices act as slave. A main synchronization processing unit configured to be provided in the master, in accordance with the vertical synchronization signal, to transmit a setting signal to the slave to perform setting on the encoding processing unit, so that a start timing of encoding processing by each of the encoding processing units is synchronized in frame image units, and to monitor a synchronization state of the encoding devices based on a state signal representing a state of the encoding processing unit of the ancillary encoding device received from the slave.

Encoding system, device, and method

A video/audio synchronization apparatus includes: a decoder configured to decode a frame contained in encoded video data and determine playback time of the frame based on a first clock signal, and decode encoded audio data and determine playback time of an associated audio signal contained in the decoded audio data and to be played back simultaneously with the frame, based on a second clock signal different from the first clock signal; a silent period detector configured to detect a silent period from within the associated audio signal; and an audio timing adjuster configured to reduce a difference between the playback time of the frame and the playback time of the associated audio signal by skipping or repeating a silent period contained within a period of the associated audio signal.

Video/audio synchronization apparatus and video/audio synchronization method

An image transmitting apparatus includes input terminals, first frame buffers corresponding to the input terminals, a write controlling portion, a read clock generating portion, a read controlling portion, an image compressing portion, and an image transmitting portion. The image transmitting apparatus inputs data on digital frame images of one frame captured with video cameras and synchronous signals synchronized with the data on the digital frame images, respectively, within a predetermined period of time; processes the data including multiplexing and compressing the data; and outputs the data on the digital frame images encoded by the image compressing portion.

Apparatus and system to multiplex data on a plurality of digital frame images into data on one frame and to encode and transmit the data

A video data transmitting devicemanages storage areasof a memory cardby equally segmenting these storage areas into partitions whose capacities are equal to each other. Image data forming video data is stored piece by piece in each partition in the sequence from a head partition toward a tail partition. Then, the image data is overwritten sequentially from the oldest, whereby the storage areasare always temporarily stored with N-pieces of image data starting from a point of the time when recording the image data and ending to a point of time tracing back for a predetermined period of time.

Video data saving device and video data saving method

To provide a technology for easily distributing an image in a requested photograph direction. Photograph images, which are photographed by turning a photographing apparatus and continuously photographing the periphery of the photographing apparatus, are stored in a storing region. Any direction in a photograph range of the photographing apparatus is specified and a distribution request of an image photographed in the specified direction is received. A reading start position on one image is determined from the continuous photograph images in accordance with the specified direction of the distribution request. A part of the photograph image is read out from the start position as a distribution image. The distribution images are read out from the positions moved correspondingly to the turns from the start position on the image following the photograph image. The distribution images are distributed to request destinations of the distribution requests.

Image distributing apparatus

An IP image transmission apparatus for TCP and UDP transmission of encoded data includes a storage medium, a first memory, a first bus, a second bus, an encoder for encoding image and audio data into encoded data and outputting the encoded data to the first bus, an encoded data transfer unit for writing the encoded data output to the first bus into the first memory through the second bus, a storage data writing controller for writing the encoded data output to the first bus into the storage medium through the first bus, and a storage data reading controller for reading storage data written in the storage medium through the first bus and writing the storage data into the first memory through the second bus.

IP image transmission apparatus

A traffic monitoring apparatus that is used to reliably detect the occurrence of an abnormal situation, such as a traffic accident. An imaging device produces and outputs images of a point to be monitored at predetermined intervals. Image inputting unit of the traffic monitoring apparatus inputs images output from the imaging device. Move vector extracting unit first generates a background image from a plurality of images input, then specifies areas where a moving object exists by calculating the difference between the background image and a newly input image, and then extracts move vectors from the specified areas. Parameter calculating unit calculates the slope and intercept, being parameters, of a move vector by considering the move vector as a segment. Plotting unit plots parameters for each move vector in a two-dimensional coordinate system with slope and intercept as its bases. Abnormality judging unit judges, in the case of the parameters being plotted in an unusual area, that an abnormal situation has occurred and informs a control center etc. (not shown) via a network of this.
