摘要： An apparatus and method for broadcast signal frame using layered division multiplexing are disclosed. An apparatus for generating broadcast signal frame according to an embodiment of the present invention includes a combiner configured to generate a multiplexed signal by combining a core layer signal and an enhanced layer signal at different power levels; a power normalizer configured to reduce the power of the multiplexed signal to a power level corresponding to the core layer signal; a time interleaver configured to generate a time-interleaved signal by performing interleaving that is applied to both the core layer signal and the enhanced layer signal; and a frame builder configured to generate a broadcast signal frame including a preamble for signaling time interleaver information shared by the core layer signal and the enhanced layer signal, using the time-interleaved signal.

摘要： A system and method for real-time data transfer on a system-on-chip (SoC) allows MIPI-CSI (camera serial interface) data received on a first interface to be output on another MIPI-CSI interface without using system memory or delaying the loopback path. The system includes a CSI receiver, a loopback buffer, and a CSI transmitter. The loopback buffer is used for the data transfer between the CSI receiver and the CSI transmitter. The CSI transmitter receives a payload included in a data packet from the CSI receiver by way of the loopback buffer. The CSI receiver communicates a packet header of the data packet to the CSI transmitter. The CSI transmitter reads the payload from the loopback buffer based on the packet header and at least one of a buffer threshold capacity and payload size.

摘要： An enhanced LOng RAnge Navigation (eLORAN) system may include a plurality of eLORAN stations, each having an eLORAN antenna and an eLORAN transmitter that may transmit data over an eLORAN data channel and may transmit a series of eLORAN navigation RF pulses. An eLORAN control station may generate station specific eLORAN data and non-station specific eLORAN data, divide the non-station specific eLORAN data into non-specific eLORAN data subsets, and cause each eLORAN station to transmit the station specific eLORAN data and a corresponding non-station specific eLORAN data subset over the eLORAN data channel in a manner to optimize data throughput.

摘要： The present disclosure provides a method, apparatus, and device for PPTP VPN based access acceleration. A PPTP VPN system includes a client-side, a first server, a VPN server, and a second server cluster supporting a GRE protocol connected between the first server and the VPN server. When the client-side starts an accelerated access, the first server receives a first PPTP message and a first GRE message from a same client-side, and encapsulates the first GRE message. An encapsulated first GRE message and the first PPTP message are send to a same second server. The first GRE message is encapsulated and the source addresses of the first GRE message and the first PPTP message are changed. Therefore, the reliability of the transmission can be achieved. Reverse transmission is no difference. The present disclosure accelerates the access speed of the VPN server and improves the access quality of the user.

摘要： In a method of generating a field of a physical layer (PHY) preamble of a data unit, information bits to be included in the field are generated. Respective sets of tail bits are appended after respective sets of information bits corresponding to respective ones of a plurality of groups of subfields of the field, each group including one or more of the subfields of the field, to generate an encoder input bit stream. One or more padding bits are added to the encoder input stream to generate a padded encoder input bit stream, the one or more padding bits to ensure an integer number of puncturing blocks in an encoded output bit stream. The padded encoder input bit stream is encoded to generate the encoded output bit stream. The field is generated to include at least some bits from the encoded output bit stream.

摘要： Representative implementations of devices and techniques provide communication between networked nodes operating on a communication network medium. In an implementation, a node generates a broadcast frame that includes at least a preamble and a payload. The preamble of the broadcast frame may include supplemental information. The supplemental information may be associated with one or more symbols of the preamble. The supplemental information may contain predetermined header information for use by nodes operating on the communication network medium.

摘要： In one embodiment, a decapsulating network device receives a plurality of encapsulated packet fragments of an original packet, and decapsulates them into respective decapsulated packet fragments. The decapsulating network device caches an inner header of the original packet from one of the decapsulated packet fragments, and in response to caching the inner header, and for each particular decapsulated packet fragment as it is received and decapsulated: prepends the inner header and fragmentation information to the particular decapsulated packet fragment; and forwards the particular decapsulated packet fragment with the prepended inner header and fragmentation information from the decapsulating network device toward a destination of the original packet.
