Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0026] According to the transmission specification of TS (Transport Stream) in the radio and television network, the input MAC data packet is fragmented, and the data is transmitted in the radio and television network in the form of TS flow, and the output is repackaged, and the TS stream is The MAC data in the network is extracted and repackaged; the algorithm of MAC OVER DVB is realized, that is, the GW realizes fragmented QPSK modulation, which is simulated transmission in the HFC network, and QPSK demodulation and packetization is realized at the CM (Cable Modem, fiber cable modem) .

[0027] see figure 1 , the server serves as the information source, and sends it to the GW (Gate Way, gateway) through Ethernet. After receiving the Ethernet frame, the GW first unpacks and filters out valid ...

Abstract

The invention provides a splicing packing method for a MAC frame of an Ethernet, belonging to the field of data communication, which solves the problem of integration of three networks in the prior art. The invention provides a splicing packing method for the MAC frame of the Ethernet. The method includes that splicing is carried through on the MAC frame after a gateway receives the MAC frame and adds marks and control information on the MAC data after splicing to combine a TS flow and transmit to an HFC network by a QPSK modulation module; a CM carries through QPSK modulation by a DVB-S tuner and combines into the step for the MAC frame to send to a PC according to the marks and control information in a packet. By adopting the scheme of the invention, digital video broadcast transmission of MAC data is realized and the problem that the access network is not unified in the integration of the three networks is solved.

Description

technical field [0001] The invention relates to the technical field of cable TV transmission and reception, in particular to a fragmentation and packetization method of an Ethernet MAC frame in the triple play technology. Background technique [0002] With the rapid development of information technology, great changes have taken place in people's way of life and work, and more and more diversified services are needed. The three major industries of telecommunication network, computer network and cable TV network are all looking for a larger market space, and are tending to penetrate and integrate with each other. Therefore, triple play is an inevitable trend of network development. The main difficulty of the current "triple play" is the access network problem (the last mile problem), including network terminals, network units, distribution units, line terminals and transmission media. [0003] In the Cable Modem (cable modem) technology, a two-way asymmetric technology is a...
