Abstract: A communication system is provided which includes: a portable terminal; a mobility management device that manages mobility of the portable terminal; a first gateway that connects the portable terminal to a first network; and a second gateway that connects the portable terminal to a second network. Based on a result of determining whether to connect the portable terminal to the first network via the first gateway or connect the portable terminal to the second network via the second gateway, the mobility management device switches between causing the portable terminal to use first contract information for connection to the first network via the first gateway and causing the portable terminal to use second contract information for connection to the second network via the second gateway.

Abstract: Provided is an image encoding apparatus capable of encoding a region important to a user with high quality. An update interval index calculation unit calculates an update interval index representing an index having a long update interval in an entire update tile overlapping the update region for each update region. An importance region specification unit specifies an important region, from each update region by using the update interval index. An quality control unit allocates a code amount, which is larger than a result obtained by dividing the total target code amount per one frame proportionally according to a ratio of an area of an entire important region with respect to an area of an entire update region, as a target code amount of the entire important region and specifies a quality value of the entire important region on the basis of the target code amount.

Abstract: A removal region detection means detects a rectangular non-update region from a circumscribed rectangle of all update blocks. An update region dividing means divides the circumscribed rectangle of all update blocks into two or more rectangular update regions not including the detected non-update region. If the number of update regions after the division does not exceeds a threshold, a division processing control means recursively applies the processing by the removal region detection means on the update regions after the division, and recursively applies the processing by the update region dividing means based on the detected non-update region. The division processing control means terminates repetition of the division processing of the update region on a condition that a new non-update region is not detected any more by the removal region detection means, or that the number of update regions exceeds the threshold, whichever is satisfied earlier.

The coefficient encoding unit has: a unit for collectively encoding the wavelet transform coefficients included in the coefficient group; a unit for individually encoding; a unit for extracting, as a mode determination reference coefficient group, a group of already-encoded wavelet transform coefficients located spatially in neighborhood of the encoding target coefficient group; and a unit for comparing the sum of the absolute values of the wavelet transform coefficients included in the mode determination reference coefficient group with a predetermined threshold, and determining whether to collectively encode or individually encode the wavelet transform coefficients included in the encoding target coefficient group.

Abstract: The moving image region detection device includes an updated block detection means, a natural image updated block determination means, and a moving image block extraction means. The updated block detection means compares pixel values between a frame of an input video and the previous frame, and detects a block including a pixel in which a value having been changed, as an updated block. The natural image updated block determination means calculates an index value representing a degree of continuity of changes in pixel values in the updated block, compares the calculated index value with a threshold, and determines whether it is an updated block of a natural image. The moving image block extraction means extracts a block determined to be an updated block of a natural image a given number of times or more in most recent frames including the frame, as a moving image block of a natural image.

Abstract: An updated region encoding unit detects an updated region in a frame of an inputted image signal and encodes the updated region. A retransmission candidate tile extracting unit extracts from within a screen a tile which does not belong to an updated region in a current frame and which is a partial region transmitted after encoded with a quality equal to or less than a first quality. A character likelihood estimating unit, with respect to a tile extracted by the retransmission candidate tile extracting unit, calculates a likelihood value indicating likelihood that the tile is a character region. A character-likelihood-order intra update unit selects a tile in decreasing order of the likelihood value from among tiles extracted by the retransmission candidate tile extracting unit, and encodes the tile with a second quality which is higher than the first quality and transmits the result.

Abstract: This moving image coding device has an update region detection unit, a coding target region detection and cache update unit, and a coding unit. The update region detection unit compares a reference frame and a current frame, and detects an update region that a pixel value changed. The coding target region detection and cache update unit replaces an image of an update region in the reference frame with an image in a cache frame, and thereafter, detects a region that a pixel value changed as a coding target region and stores an image of a region that a pixel value did not change for a predetermined past period in the image of the update region in the reference frame before the replacement, into the cache frame as an image of a stable region. The coding unit codes an image of the coding target region and cache information.
