This invention is directed to the provision of a moving image data editing apparatus 1 for applying masking to a portion of an image by editing moving image data in which each frame is divided into pixel blocks of a predetermined size and encoded on a pixel block basis. Moving image data editing apparatus 1 comprises: pixel block extracting means 11 for extracting from an input data stream of moving image data 71 pixel blocks BL2 and BL4 that are located within the region 72 to which masking is to be applied; fixed pattern inserting means 12 for inserting precoded fixed pattern data 73 into the original positions of extracted pixel blocks BL2 and BL4 in the data stream; and pixel block inserting means 13 for inserting extracted pixel blocks BL2 and BL4 as user data into the data stream.

The present invention provides a multiplexing device, multiplexing method, and multiplexing program that allow an optional character string to be easily multiplexed with video online. The multiplexing processing unit multiplexes a dummy character string with the respective encoded data for video and audio. The multiplexed data are stored in the multiplexed data storage unit. The multiplexing processing unit stores the position (first dummy point) in which the dummy character string data were stored in the dummy point storage unit. The character string substitution processing unit substitutes the dummy character string data for the optional character string data to be inserted that has been input from the character string input unit on the basis of a first dummy point. The substituted multiplexed data are output as a multiplexed file from the file generation processing unit.

摘要:
A CPU, a main memory, a network interface section and a control section are connected to an internal bus. The control section is connected to a storage device to control read-out and write-in processes relative to the storage device. The network interface section receives an access request to the storage device transferred through a network and sends it to the control section through the CPU. The network interface section and the control section are connected to each other by an exclusive line. Data read out of the storage device and data to be written into it is transferred through the exclusive line.

摘要:
An image processing system which efficiently generates a desired special effect with a simple circuit. In order to add special effects to a given source picture, a target area specifying unit first specifies a target area, as part of the given source picture, which is to be subjected to a special effect generation process. The source image is coded by an image data coding unit, and the resultant coded data is then modified by a target data relocation unit, Here, part of the coded data, or target data in the target area, is extracted and relocated from its original field to a different field of the coded data. An image data transmission unit transmits the coded bitstream which contains the relocated target data. At the receiving ends, a target data extraction unit extracts the target data from the received coded bitstream, which is then saved into a target data storage unit. A data reproduction unit reproduces the original coded data or imperfect coded data from the received data, where the latter lacks the target data. The data decoding unit decodes the coded data or the imperfect coded data to reconstruct a picture.
