Problems solved by technology

[0006] This method can also use the BootP protocol to replace the DHCP protocol, but there are two disadvantages in the BootP protocol: one, before configuration, the server must know the MAC address of the IP set-top box; two, the IP address is statically bound, when the IP resource is insufficient , it may cause a waste of IP addresses
When there are a large number of users in the network, but the IP resources are insufficient, and there will not be more than the total number of users logging in to the network at the same time, the static binding IP of the BootP protocol will cause an IP conflict problem.

specific Embodiment approach

[0029] The first step is to install the DHCP client program in the ROM chip of the IPTV set-top box.

[0030] In the second step, as shown in the (1) step of accompanying drawing 2, the IPTV set-top box starts, and the ROM chip starts the DHCP client program initialization TCP / IP. The set-top box sends a lease IP address request packet to the network through UDP port 67. The content in the packet is the MAC address of the network card of the set-top box and the logo of the set-top box, as well as the broadcast source IP address 0.0.0.0 and the destination IP address 255.255.255.255. The request packet format is as follows:

[0031] Source IP address 0.0.0.0

Destination IP address 255.255.255255

MAC address and identification of IPTV set-top box

[0032] The third step, as shown in the (2) step of the accompanying drawing 2, after all the DHCP servers in the network receive the request, if there is an idle IP address, a confirmation message will be sen...

Abstract

A method for dynamically distributing IP address on set-top box includes connecting client end module to IPTV set top box of Internet and using service end module to distribute and manage DHCP server of IP, utilizing set-top box at client end to monitor UDP port 67 and to send IP address leasing request as well as to configure TCP / IP, using server at service end to receive IP address leasing request of set -top box and to return confirmed IP address back as well as to change IP address mapping table on server.

Description

technical field [0001] The invention relates to the field of computer network communication and some related network communication protocols. Background technique [0002] IPTV receiving terminal, that is, IPTV set-top box, is one of the key equipment of IPTV system. Its main functions include: supporting LAN or xDSL network transmission, receiving and processing IP data and video stream; supporting H.264, MPEG-2, MPEG-4 , WMV and Real video decoding; support corresponding CA technology; support HTML web browsing and online games, etc. [0003] Since IPTV is based on network transmission, the set-top box as a network access device should be set with network parameters such as IP address and gateway before use. If it is manually set up one by one in the actual project, it will greatly increase the labor cost of the operator, and the maintenance cost in the future will also increase accordingly. Therefore, in the design of the IPTV set-top box, the plug...
