access technologies have emerged. From the use of telephone lines as the transmission media xDSL, to the use of Cable Modem by Cable TV cables, to Ethernet access by man, various new technologies emerge one after another, and the upgrade is extremely fast. XDSL broadband access includes ADSL, CDSL, HDSL, IDSL, UDSL, and so on. A typical example is ADSL, which is an asymmetric digital user line. ADSL is considered to be one of the access technologies

-to-point or point-to-point network structures. You can choose to operate in licensed frequencies or licensed spectrum, depending on your needs for service levels, the maximum transmission distance of WiMAX is 31 miles. WiMAX and Wi-Fi, 3G, and DSL will coexist in a long period of time, and compete with each other in the overlap area to a certain extent. I. WiMAX and DSL XDSL can be divided into symmetric rate and asymmetric rate based on the same upstream and downstream speeds. XDSL with symmet

applications. User complaints are increasing, and remote users need fast and high-quality access methods. Especially with the emergence of emerging network applications in recent years, the requirements for network bandwidth and the sensitivity to latency are getting higher and higher. The maximum speed of PSTN dial-up access is 56 kbps, which is far from meeting today's application requirements. Therefore, some access technologies have emerged.

that the line speed can be changed based on the change of the line quality.◆ IDSL: isdn dsl is a DSL Based on ISDN technology. Security drawbacks of permanent connections Broadband access network Internet is booming. It has been reported that in the past five years, China will become the cheapest part of the world's broadband access network. Therefore, achieving permanent connections and online anytime is no longer a distant dream. At the same time,

1 IntroductionMPEG-Ⅱ has been widely used as an international standard for motion images. Digital Video Broadcast (DVB) has used MPEG-Ⅱ as a source format. In many practical applications, including satellite broadcasting, digital cables, and high-definition TV HDTV, MPEG-Ⅱ groups are input to channels through synchronous interfaces of encoder. In the broadband digital communication network, for example, ADSL, FTTC and broadband IDSL convert the MPEG-Ⅱ
