Abstract:
Disclosed is a Bluetooth® moving picture stream transmission terminal for moving picture data stream transmission through Bluetooth® to a moving picture output device. The Bluetooth® terminal provides the moving picture output device with the optimized streaming service by either acquiring the transcoding reference variable according to decoding function included in the moving picture output device when the Audio Video Distribution Transport Protocol (AVDTP) channel of the moving picture output device is opened, or acquiring the transcoding reference variable by using the newly defined transcoding reference variable request/response message after opening the AVDTP channel, and by setting an encoding environment with reference to the acquired transcoding reference variable, and encoding the corresponding moving picture and transmitting stream of the encoded moving picture through Bluetooth®.
Abstract:
The present invention relates to a method of controlling the characteristics of a double relaxation oscillation SQUID having a reference junction. In the method of controlling characteristics of a reference junction-type double relaxation oscillation SQUID (RJ-DROS) having a signal SQUID and a reference junction, a reference DC current flows through the reference junction in order to control the characteristics of the DROS. A modulation width of an averaged relaxation voltage, which reacts to a magnetic flux, may be controlled at the reference junction. An amount (modulation depth) of an averaged relaxation voltage, which reacts to a magnetic flux, may be controlled at the reference junction. An amount of an operation application current may be controlled at the reference junction. Accordingly, the reference current of the reference junction can be changed by causing the current to flow through the reference junction. A magnetic flux-voltage characteristic and a transfer coefficient of the DROS can be easily controlled externally and the DROS can operate stably.
