Method for generating two-direction set top box MAC address

Abstract

The invention discloses a method for generating a two-direction set top box MAC address. A customized electronic registration code chip is adopted to automatically achieve the generation of the MAC address, each time when a set top box is started, information is extracted from a silicon serial number of the electronic registration code chip to automatically generate the MAC address, the characteristic that the electronic registration code chip is customizable and the uniqueness of the electronic registration code chip are utilized to guarantee the uniqueness of the MAC address and complete software automatic generation of the MAC address, and no extra hardware cost is needed. In the process of generating the MAC address through set top box software, four layers of judgment including CRC verification judgment, family code verification judgment, user identification code judgment and user defined number section judgment are conducted in sequence, and reliability of serial number data is guaranteed. Each time when the set top box is started, an electronic registration code is utilized to generate the MAC address, and therefore during the service life of the electronic registration code chip, the MAC address is always safe and effective.

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. Assign yourself. 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-t...
