摘要:
A system of detecting a motion vector for an object block in a current frame of an orthogonally transformed video with respect to a stored reference frame. The motion vector is detected by: extracting a predetermined pattern of lower frequency components from the object block; orthogonally inverse transforming the extracted lower frequency components within the pattern to yield the pattern of pixel data; searching the reference frame for a block having a maximum correlation with the pattern of pixel data; and calculating the motion vector from the object block to the block having a maximum correlation. As an orthogonal transform, DCT (discrete cosine transform) is preferable. Creating a row and a column image comprising sums obtained by adding all the pixels in each column and each row of the object block and applying the above searching and calculating process to the row and the column image enables the motion vector detection from a normal or noncompressed video.

A multimedia title including sources of plural data-types such as a motion picture, still picture and text data, presentation methods of respective sources, and the data-types is edited in every frame, so that a video signal is created. Based on a scenario, the video signal is coded adaptively to respective data-types of each source. As a result, calculation volume is reduced and picture quality is improved.

A system is arranged by a service providing apparatus 109 for storing a plurality of contents data 110 and capable of transmitting the contents data via network interfaces 116a/116b and a communication path 112; and also a service relaying apparatus 101 for producing compressed moving picture data having a high image quality from still picture data, and capable of transmitting the compressed moving picture data via network interfaces 115a/115b and another communication path 111 to a reproducing terminal 106. As a result, desirable contents data can be displayed by the reproducing terminal which owns a capability of displaying the compressed moving picture data, but does not own such a capability of displaying the desirable contents data.
摘要:
A picture coding apparatus contains a rate control unit 100, an image buffer 200, an orthogonal transformation unit 300, a quantizing unit 400, a variable length coding unit 500, a motion predicting unit 600, a coding unit 700, and an output buffer 800. The rate control unit 100 allocates a target code amount to each of pictures, and transfers a quantizing value 100a which is determined by a code amount to the quantizing unit 400. This target code amount is calculated by adding a reference target code amount to a correction value. The correction value is calculated based on a difference between a predetermined target value and an actual value of a remaining coding picture amount of the output buffer 800.
摘要:
A mobile device includes a position sensing unit, a remote control information obtainment unit, and a storage unit. Position information obtained by the position sensing unit is stored in the storage unit in association with remote control information. The mobile device further includes a directional space obtainment unit and an apparatus specification unit. The mobile device recognizes a direction pointed by a user using the mobile device, and enables operation of a terminal apparatus existing in the pointing direction.

The communication device can easily serve as an extended user interface such as a remote controller of a target apparatus without causing any complicated operations to a user. The communication device includes the following units. An apparatus information obtainment unit (203) obtains apparatus information from an apparatus. A position information obtainment unit (206) obtains position information of the communication device (102). An operation information obtainment unit (212) obtains operation information based on the apparatus information. A storage unit (213) stores the position information as apparatus position information indicating as a position of the apparatus, in association with the operation information. A direction sensor unit (207) detects direction of the communication device (102). A directional space calculation unit (208) calculates a directional space of the communication device (102). A selection unit (209a) specifies the apparatus existing in the directional space based on the apparatus position information and selects the operation information associated with the specified apparatus. An operation information transmission unit (215) transmits, based on the selected operation information, a control signal to the specified apparatus so as to allow the communication device to operate the apparatus.

摘要:
A laminated material suitable for fabricating miniaturized security tags which have the uniform resonance frequency, and security tags obtained by using the laminated material, are provided. A manufacturing method of a laminated material for security tags characterized in that metal foils are laminated on both sides of a previously formed synthetic resin film, and security tags obtained by using the laminated material by the manufacturing method, are provided. Because the lamination is performed on the previously formed resin film, the amount of variation in thickness of the resin film is small, and the thin resin film can be precisely manufactured. Further, because the oriented film has a relatively high strength even for a thin film, the laminated material is easy to be etched for forming a circuit. The security tag obtained by using a previously formed resin film can satisfy both uniformizing the resonance frequency and miniaturizing the security tag simultaneously, and has an excellent performance.
