Abstract: In a moving picture in which data corresponding to one picture is required for display, data corresponding to one picture is divided into line blocks including a predetermined number of pixel lines and captured as block data. A compression rate of each block data is dynamically set according to a capture point in time of each block data. Each block data is compressed at the set compression rate and transmitted to a reception apparatus through a transmission path. On a plurality of block data, a series of processes including the capture and the transmission of each block data is performed in parallel while shifting only a time required for the capture. Block data that is late in start order of the capture, among the data corresponding to one picture, is set to be lower in compression rate than block data that is early in start order of the capture.

Abstract: The present technique relates to a sending device, a sending method, and a program that can restrain a disturbance or the like of an image, the disturbance or the like being generated when the image, transmitted from a data transmission channel, is displayed with low delay. An RTP communication part obtains an adjustment quantity for adjusting a capture timing to start capturing an image, a capture adjusting part adjusts the capture timing based on the adjustment quantity, a capture part captures the image in synchronization with the adjusted capture timing, and the RTP communication part sends the captured image to a receiving device. The present technique may be applied to, for example, a sending device that captures and sends an image.

Abstract: Disclosed herein is a communication control apparatus including: a bandwidth measuring section configured to measure a physical bandwidth of data communication via a communication channel; and a rate control section configured to set a threshold that does not exceed the physical bandwidth measured by the bandwidth measuring section, cause a rate of the data communication to increase exponentially up to the threshold, and cause the rate to decrease when the rate has reached or exceeded the threshold but not reached the physical bandwidth.

Abstract: There is provided a communication apparatus including: a transmission unit which transmits data to an opposite communication apparatus; a physical band measurement unit which measures a physical band against the opposite communication apparatus; and a rate control unit which controls a transmission rate of the transmission unit within a range of the physical band when a previous transmission rate of the transmission unit is below a value of subtracting a predetermined value from the physical band and within a range of exceeding the physical band when the previous transmission rate is beyond the value of subtracting the predetermined value from the physical band.
