A stereoscopic video processing system includes an output image generator configured to generate interpolation frames in interpolation phases using the frames of the input video signal and the motion vector and output the frames of the input video signal or the interpolation frames as the frames of an output video signal. The stereoscopic video processing system further includes an output controller configured to (i) determine whether frames of the input video signal include image regions with motion based on the motion vector, (ii) control the output image generator to output the interpolation frames upon determining the frames of the input video signal include the image regions with motion, and (iii) control the output image generator to output the frames of the input video signal upon determining the frames of the input video signal does not include image regions with motion.

Performing video processing for frame sequential display for alternately displaying right and left images of stereoscopic video signals

The instant application describes a stereoscopic video processing system that includes a vector detector configured to detect a motion vector associated with frames of an input video signal; an output image generator configured to generate interpolation frames based on the frames of the input video signal and the motion vector and to arrange the frames of the input video signal and the interpolation frame along a time axis; and an output controller configured to control the output image generator to output the interpolation frames as the output video signal alternately at intervals of one frame and two frames, and output the frames of the input video signal between the one frame and the two frames of the interpolation frames.

Generation interpolation frames

A parallax detector detects a parallax between a left-eye image and a right-eye image of an input stereoscopic image signal. A vector detector detects an inter-frame motion vector in the stereoscopic image signal. An output controller determines whether or not to generate an interpolated frame based on the detected parallax and motion vector, and outputs a control signal indicating a result of the determination. An output image generator generates an interpolated frame having an interpolation phase using the motion vector when the control signal indicates that an interpolated frame is to be generated.

A communication system includes a device and a server connected to the Internet, which transfers communications between the device and a terminal connectable to the Internet via the server. The device periodically transmits a notice packet to the server. The server transmits a connection request packet to the device in reply to the notice packet when a transfer to the device is requested from the terminal. The device transmits a TCP connection request to the server when receiving the connection request packet from the server. The server accepts the TCP connection request transmitted from the device to the server in reply to the connection request packet, to establish the TCP connection. Thus, the server transfers communications between the terminal and the device on the TCP connection after the TCP connection is established.

It is objected to simplify a procedure concerning bandwidth acquisition. Bandwidth acquiring meansof a second transmitting apparatusacquires a bandwidth which was used by a first transmitting apparatusby using a propagation delay identifierread from first transmitting apparatusand a maximum transmission data sizeafter stopping transmission of first transmitting apparatus. Each apparatus is composed so that transmission is started using this bandwidth and because returning and re-acquisition are not accompanied when the transmission is switched, necessary procedure can be simplified. Further, it is possible to effectively use the bandwidth by using a propagation delay identifier.

When a plurality of display parts, or icons, such as &ldquo;play&rdquo; or &ldquo;stop&rdquo; are displayed on a screen, information about the positional relationship in which these icons will be laid out on the screen is first assigned as an attribute of each icon. Also, using a certain icon as a reference, information about the layout of the icons, such as whether they are above, below, to the left, or to the right of this icon, is assigned as an attribute of the icon serving as the reference. In this way it is possible to vary the layout of a display according to the size of the display screen.

A data transmitting device connected to a prescribed network includes a coding device for receiving plural kinds of coded data, and coupling these coded data in first data units to generate a first coded stream. A divider divides the first coded stream into second data units of a prescribed data size to generate divided pack data corresponding to divided packs as the second units. A packet generating device adds header information to respective divided pack data to generate packet data corresponding to packets as data transmission units; and a transmitter outputs the respective packet data toward the network as a second coded stream which has a data structure different from that of the first coded stream.

In transmission and reception of signals in which audio data and management information used in playback are mingled, such as the data recorded in DVD or other recording media, this is to present means for separating the information into video and audio data and management information used in playback, so that the reception side can make use of various playback functions, such as a playback of original picture and sound information, a change of playback procedure, and a selection of playback information. At the transmission side, the data packet transforming means generates a first packet stream from transmission data. Consequently, the transmission packet generating means inserts packets generated from the playback management information by playback management information packet transforming means into the first packet stream at a specified rate, and generates a second packet stream. This is transmitted by using communication media as designated in IEEE1394 or the like. At the reception side, the signal acquired in the receiving means is separated into a packet stream of data and packets of playback management information in the packet identification means, so that the playback data is restored from the packet stream of data on the basis of the management information.
