    摘要： In an MPEG-2 decoding system, a transport decoder decodes a transport packet corresponding to a Program Identification (PID) from an input transport stream, and retrieves a Program Association Table/Program Map Table PAT/PMT) from the stream when it is requested to retrieve Program Specific lnformation (PSI). A pre-decoder checks PSI stored in a PSI memory in response to a request to change to a desired channnel, reads PIDs of transport packets for a Packetized Elementary Stream (PES) of a program corresponding to the desired channel from the PSI memory to provide it to the transport decoder, receives the PAT/PMT and updates the contents of the memory using the PAT/PMT. After decoding, PSI previously extracted therefrom is stored in the memory. PIDs of transport packets for the PES of desired program are obtained referring to the stored PSI, and transport packets having the PIDs are retrieved and decoded.

    摘要： In an MPEG-2 decoding system, a transport decoder decodes a transport packet corresponding to a PID from an input transport stream, and retrieves a PAT/PMT from the stream when it is requested to retrieve PSI. A pre-decoder checks PSI stored in a PSI memory if a request to change to a desired channel is made, reads PIDs of transport packets for a PES of a program corresponding to the desired channel from the PSI memory to provide it to the transport decoder, receives the PAT/PMT from therefrom at a predetermined time, and updates the contents of the memory using the PAT/PMT. When a transport stream is decoded, PSI is previously extracted therefrom and stored in the memory. Upon the channel change request, PIDs of transport packets for the PES of the desired program are obtained referring to the stored PSI, and transport packets having the PIDs are retrieved and decoded.

    摘要： A system and method for assigning IP addresses in an Ethernet passive optical network which includes one OLT (Optical Line Terminal) and a plurality of ONTs (Optical Network Terminals) connected to the OLT are disclosed. The method includes the steps of including a dynamic host configuration protocol (DHCP) server in the OLT, establishing IP address pools including at least one IP address according to the ONTs, and searching for an ONT from a MAC processing section of the OLT by means of a MAC address from which IP address assignment is requested when IP address assignment is requested from one of the ONTs. The ONT is connected to a DHCP client. The DHCP server assigns an available IP address existing in an IP address pool established for the ONT having requested the IP address assignment according to ONTs.

    摘要： A connector assembly for coupling a corrosive gas supply pipe with a glass tube in an apparatus for fabricating an optical fiber preform using vapor deposition is disclosed. The connector assembly includes a first connector formed on an inner periphery thereof with a threaded portion, a second connector having a stepped surface on an inner surface and formed on an outer periphery with a threaded portion threadedly engaged with the first connector, an O-ring installed in the first connector and in close contact with the stepped surface when the second connector is threadedly engaged with the first connector, and resilient means for urging the O-ring against the stepped surface. The connector assembly consistently applies a resilient force to the O-ring functioning as a seal between the first and second connectors. For a long-running operation, even though the O-ring is cured, the fitting maintains a consistent sealing state to prevent metal material from being oxidized by the corrosive gas. As a result, fine oxidized metal particulars do not infiltrate into the gas supply pipe to prevent the optical fiber preform from deteriorating.
