摘要:
An object of the present invention is to enable a real-time distribution even if the band of a network varies. A distributing apparatus receives a packet retransmission request or a packet restoration notification, which is transmitted from a receiving apparatus, with an error information receiving unit. If the number of received retransmission requests or that of restoration notifications becomes equal to or larger than a certain value, a distribution band controlling unit decreases a band used to distribute a packet by a certain band.

Provided is a Schottky emitter having the conical end with a radius of curvature of 2.0 μm on the emission side of an electron beam. Since a radius of curvature is 1 μm or more, a focal length of an electron gun can be longer than in a conventional practice wherein a radius of curvature is in the range of from 0.5 μm to not more than 0.6 μm. The focal length was found to be roughly proportional to the radius of the curvature. Since the angular current intensity (the beam current per unit solid angle) is proportional to square of the electron gun focal length, the former can be improved by an order of magnitude within a practicable increase in the emitter radius. A higher angular current intensity means a larger beam current available from the electron gun and the invention enables the Schottky emitters to be used in applications which require relatively high beam current of microampere regime such as microfocus X-ray tube, electron probe micro-analyzer, and electron beam lithography system.

When error correction data, which is to be inserted into transmission data at specific intervals, is generated by calculating exclusive-OR of the transmission data, cumulative exclusive-OR of the transmission data is continuously calculated independent of the error correction data insertion intervals. Exclusive-OR between a calculation of the exclusive-OR at the time of the previous error correction data insertion and a calculation of the exclusive-OR at the time of the current error correction data insertion is calculated, thereby generating error correction data to be inserted at the present time. This provides efficient error correction data calculation.
