Multiple devices to accept MPEG II video stream channels

摘要

An object of the present invention is to provide a DS3 multiple device for multiplexing the MPEG II video stream 6 channel DS3 by installing a remote device in close proximity to the subscriber.;In order to achieve the above object, the present invention generates a 6.46 Mb / s (hereinafter referred to as 6.5 M) frame signal in an MPEG II video stream in one step. In order to make this signal a signal that can be accommodated in a DS3 frame, three 6.5s are first multiplexed into 20.1312Mb signals. The 20.1312Mb signal frame accepts three 6.5M signals and has a frame structure consisting of a 12-bit FAW (Frame Alignment Word), maintenance-related M & A channels, and other overhead. Two 20.1312 Mb / s frames are used to form a DS3 frame, which accommodates six MPEG II video streams in the DS3 frame.
