Internet Factors The speed of development of the Internet has been phenomenal. Today almost every household has access to computers (non-poor areas) and can connect to the Internet to watch TV. Therefore, the first, must have a network, just as its name - HD network set-top boxes (HD set-top boxes) as the name suggests has a network. Next look at how much bandwidth?
How much is the bandwidth? Although the broadband coverage is relatively wide, but in fact the bandwidth of different regions is not the same, we calculate according to the generality, if you want to see the 720P source, the bandwidth needs at least 2Mbps, popular 1080P The video needs more than 8Mbps bandwidth, provided that your bandwidth does not shrink. Usually, the bandwidth that we purchase when we handle broadband is not actually obtained. We often fail to meet the standard, so the theoretical value is not credible. It depends on the actual rate.
Look at the actual rate
360 Guardian is the software that most computer users will install (some friends like drug tyrants), actually obtain the current network speed through the measurement network speed function in the traffic firewall, when the actual rate reaches 200K/S is basically see 720P HD movie is not There will be a lot of problems, see 1080P full HD need to reach the average standard 1.3M / S, or else Calton is inevitable.
The effect of bit rate The above mentioned actual rate is suitable for most users, but sometimes there will be lower than the standard rate can see high-definition programs, that is, the effect of code rate, high code rate, corresponding to the required playback rate When it is high and the relative code rate is low, the actual rate requirement is not so high.
The TV interface can not see high-definition programs without the HD network set-top box, and your TV must have the corresponding interface settings. If you are an old-fashioned CRT TV, you should have an AV video interface. You can play 720P high-definition programs; 1080P Full HD movies require an HDMI HD interface.
