[Abstract]: This paper introduces the DVB-based Data Broadcast System (IP over DVB) developed by the Blue topology company for cable TV networks, which focuses on the system structure, the front-end system structure and implementation, and the design and implementation of the backend data receiving card. Key parts of the system: Front-End Server software, multi-protocol wrappers, and data receiving cards are independently developed by Alibaba Cloud an

Recently the project has just been delivered, and there are occasional voice and voice search features. Voice search I use is to fly the demo, the feeling is also good, interested in the words can go to the official online download demo, which said the special details, but slightly more trouble. Voice broadcast flying also has a demo, but do the development of course to seek the most concise way to deal with, after ios7.0 added some new features, whic

The three types of message exchange modes in WCF are discussed above, One-way,request/reply,duplex. The first two relatively simple, needless to say, duplex relatively complex, the above just to achieve a simple callback, in the real application, there are many noteworthy, this article on the combination of a practical example to discuss the specific application of duplex and very worthy of our attention. The starting point of this article By reading this article, you can understand the follow

standard network application uses a standard port address. For example, a Web server uses port 80. You can view the registered port addresses in/etc/services. The IP protocol layer can also use different physical media to transmit IP packets to other IP address hosts. You can add protocol headers to these media sets. For example, the Ethernet protocol layer, PPP protocol layer, or slip protocol layer. Ethernet can be connected to multiple hosts at the same time, and each host has an ethernet ad

Brief introductionBefore a manufacturer can manufacture a network card, it must register with the IEEE to obtain a vendor code length of 24bit, also known as OUI (Organizationally-unique Identifier). In the process of manufacturing the network card, the manufacturer will burn a 48bit bia (burned-in address, Cure addresses) address to each of the NIC's ROM, the first 3 bytes of the BIA address are the manufacturer's OUI, and the last 3 bytes are determined by the manufacturer itself, but differen

The IP address consists of three types: unicast address (destination is a single host), broadcast address (destination is all hosts on a given network), and multicast address (destination is all hosts within the same group).　　broadcast and multicast only apply to UDP, It is important that they transmit messages to multiple receivers simultaneously.　　TCP is a connection-oriented protocol that means that ther

from 224 to 239. the first byte of the Class d ip address starts with "1110". It is a specially reserved address. It does not point to a specific network. Currently, this type of address is used in multi-point broadcast (Multicast. A multicast address is used to address a group of computers at a time. It identifies a group of computers that share the same protocol. Multicast over an IP network is generally achieved through multicast IP addresses. Mul
