Abstract: This invention is related to an improved structure for a polishing machine of an optical disk, which comprises a motor, a turntable unit integrated with a housing, at least two polishing wheel positioned on a cover which can cover up the housing, and a timer. When the cover is closed, the polishing wheel can polish the optical disk. The primary objective of this invention is to provide a structure for a polishing machine with a precise polishing effect and higher automation to increase the quality of polishing. The secondary objective of the present invention is to provide a structure for a polishing machine which is simplified in structure, miniaturize in volume and easy to stored and used personally.

Abstract: In a method and system for the remote reception of real-time audio/video programmes, a receiver station establishes an Internet connection with a source station that is connected to a signal source, which provides a programme signal containing a plurality of channels of audio/video programmes. The source station is enabled to select one of the channels of the programme signal, to convert programme content of the selected one of the channels into digital programme data, to compress the digital programme data to result in compressed programme data, to convert the compressed programme data into a format suitable for transmission over the Internet, and to transmit the compressed programme data to the receiver station through the Internet.
