CATV Network is an efficient and inexpensive comprehensive network, it has a wide bandwidth, large capacity, multi-function, low cost, anti-interference ability, support a variety of services to connect the advantages of millions of households, its development for the development of Information superhighway laid a foundation. In recent years in China CATV Network development, the country has built more than 1500 cable

Comparison of IP transmission technology in cable TV networks Abstract: IP transmission technology in cable TV networks includes three forms: IP over ATM, IP over SDH, and IP over WDM, this article introduces and compares the three IP Address Transmission Technologies in detail. Key words: IP technology,

Cable TV NetworkAbstract: Give a graph with n points vertex, give M edge. Find the point of connectivity KAlgorithm: Each vertex v is split into V ' V ', and V '-->v ' has a capacity of 1. For edges in the original (u,v) edge u '--->v ' V '-->u '. P (u,v) for each pair of points, with u as source and V as meeting point.We just need to fix one vertex and enumerate the other sinks.1#include 2#include 3#inclu

win8.1 system notebook connection use HDMI HD cable to connect to TV no sound how to solve? win8.1 system notebook has an HDMI interface, as long as the use of HDMI high-definition cable can be connected to the monitor, LCD TV screen display, so you can operate under the large screens. But some win8.1 system friends sa

POJ 1966 Cable TV NetworkLinks: http://poj.org/problem?id=1966Test Instructions: in a cable TV network, the repeater connection is bidirectional. If there is at least one route between any two repeaters in the network, the repeater network is called connected, or the repeater network is not connected. An empty network,

The main topic: to a N-point, M-edge of the graph, the minimum point cut set of the cardinality.Problem Analysis: The base of the minimum point cut set of the graph can be changed to the minimum cut. Considering the graph of single source s single-sink T, if a minimum point set is required, so that the graph is no longer connected after the point set is removed (the number of connected components is increased), simply split each point into two (in and out points), and with a capacity of 1 arc, t
