Abstract: A transmission system transmits a series of coded frames from a transmitting device to a receiving device, using both intra-frame coding and inter-frame coding. The receiving device decodes the frames and sends acknowledgment signals to the transmitting device. The transmitting device selects the reference frame employed in inter-frame coding according to these acknowledgment signals. The method of reference frame selection can be varied according to an assessment of transmission channel quality. The assessment criteria, or the reference frame selection method itself, can be varied in response to input from a human user.

Abstract: In a belt type continuously variable speed system, when a hydraulic cylinder (110) operates, the hydraulic cylinder (110) and an elastic member (134) in a tensioner (104) draw a belt (102) against an elastic member contained in a variable radius pulley (107). Consequently, a power transmission ring contained in the variable radius pulley (107) is made eccentric from the axis of the variable radius pulley. The power transmission ring is displaced to the position where a force produced by the hydraulic cylinder (110) and the elastic member (134) in the tensioner (104) to make the power transmission ring eccentric and a force produced by an elastic member contained in the variable radius pulley (107) to urge the power transmission ring toward a position which is concentric with the axis of the variable radius pulley (107) are balanced with each other, thereby achieving speed variation.
