    摘要： As the video signals of macroblocks are coded, they are stored in a buffer. When the total code length of the stored macroblocks exceeds a predetermined value, all but the most recently coded macroblock are output from the buffer as a video packet, and the most recently coded macroblock is coded again. To minimize this occurrence, when each coded macroblock is stored, the code length of the next macroblock is predicted and added to the total length, and if the resulting sum exceeds the predetermined value, all of the coded macroblocks stored in the buffer are output as a video packet.

    摘要： A videophone takes a live picture of the user, sends the live picture during part of a call, generates a processed picture different from the live picture, and sends the processed picture during another part of the call. The processed picture may be prepared in advance, or may be generated by combining the live picture with a prepared picture. Alternatively, the processed picture may be obtained by increasing a quantization coefficient of the live picture, producing a mosaic effect that disguises the live picture. The processed picture can be sent to protect the privacy of the videophone user, or to provide appropriate transition at the beginning or end of the call. The processed picture can also be sent when the call is placed on hold.

    摘要： An image encoding device is provided that can transmit encoded image data without lowering the frame rate even when the transmission speed of the transmission path is lowered. An encoded region designator selects the region that is to be encoded, in the input image, depending on the bit rate of the transmission path. Only such a region that is designated by the encoded region designator is encoded. The encoded region designator may be one which selects the region that is to be encoded, according to the bit rate of the transmission path, and the motion vector detected by the image encoding circuit. As an alternative, an encoded region designator may be used which selects the region that is to be encoded according to the bit rate of the transmission path, and the information on the designated region supplied from the outside. Also, a selector limiting the number of bits of the signal from the image signal input circuit may be provided, and when the bit rate of the transmission path is lowered, the number of bits of the input image may be adaptively switched.

    摘要： When a detected value of the signal processing speed from a frequency comparator is larger than a prescribed value input from an input terminal, the rotation control of a disk is switched from constant linear velocity control to constant angular velocity control using an error signal from an arithmetic unit. Alternatively, when a detected value of the rotational velocity from a frequency comparator is larger than a prescribed value input form an input terminal, the rotation control of the disk is switched from the constant angular velocity control into the constant linear velocity control.
