A method for generating the mac address of a two-way set-top box

Abstract

The invention discloses a method for generating the MAC address of a two-way set-top box. A customized electronic registration code chip is used to automatically complete the generation of the MAC address. When starting up each time, the information is extracted from the silicon serial number of the electronic registration code chip to automatically generate the MAC address. , using the customizable characteristics and uniqueness of the electronic registration code chip, the uniqueness of the MAC address is guaranteed, and the software of the MAC address is automatically generated without additional hardware costs; in the process of generating the MAC address by the set-top box software, it has passed the CRC calibration successively. verification, family code verification, user identification code judgment, user-defined number segment judgment and other four-layer judgments to ensure the reliability of the serial number data; the set-top box will use the electronic registration code to generate a MAC address every time it is turned on. Therefore, During the service life of the electronic registration code chip, the MAC address is always safe and valid.

Description

technical field [0001] The invention relates to the technical field of digital television, and more specifically relates to a method for generating a two-way set-top box MAC address. Background technique [0002] With the development of digital TV, two-way set-top boxes have become the mainstream of the market, and network functions have gradually become common functions of set-top boxes. MAC (Media Access Control) address is a set of 48-bit long binary numbers used to identify the location of network devices and is globally unique. The 0-23 bits of the MAC address are called organizational unique identifiers (organizationally unique, OUI), which are the identifiers for identifying LAN (local area network) nodes. Each network equipment manufacturer will have its own fixed OUI, and the 24-47 bits are determined by the set-top box manufacturer itself. distribute. The distribution of the MAC address of the two-way set-top box is to determine the 24-47 bits of each two-way set...
