With the continuous improvement of optical fiber networks, watching television programs through the Internet has become a mainstream nowadays. Therefore, major operators have launched broadband-based television services to seize the user's living room. Mobile, telecommunications, and Unicom provincial companies all have their own TV services. Many users are tangling up to which one to choose? In fact, before we choose, we first understand the difference between the two, and then according to our own needs, we can determine what suits them. Picture from the network At present, TVs of operators can be divided into two categories: IPTV and OTT. First of all, under IPTV, only IPTV and Unicom have IPTV licenses. Currently, there is only one IPTV service in a province. Business, so the south is telecommunications, north is China Unicom. Advantages of IPTV: There is no delay in live broadcasting, and on-demand broadcasting is not possible. If you have an elderly person in your home, you have to watch live broadcasts, or you want to choose an alternative to the current cable TV, first choose IPTV, because IPTV is approved by broadcasting and television, with live broadcasting qualification, no delay in live broadcast, IPTV again It is an independent channel and does not occupy bandwidth. That is, TV and broadband are separate and will not affect your access to the Internet. However, some people have doubts at this time, Telecom or China Unicom's IPTV is a line, how can the same PON port does not occupy bandwidth? In fact, this is the advantage of fiber optics. An optical fiber can carry at least 1G of traffic. However, at present, the home bandwidth is basically 100 megabits. That is, the capacity of the optical fiber is large enough. The television will allocate 100 M to you, and then use technical means. Distinguish whether the user's traffic is Internet traffic or TV traffic, so IPTV will never affect your access to the Internet, but if it is ADSL it is impossible to achieve, such as the ADAL largest bearer is 4M, there is no way to give you separate bandwidth, this time to see TV will certainly affect the Internet. Secondly, IPTV is less likely to affect the external network on the intranet. Disadvantages of IPTV: Due to intranet transmission, there is no open Internet set-top box, so the content resources are relatively scarce, and there is a large amount of paid on-demand content. If you have a bear child at home, you must remember to set a consumer password to avoid unnecessary expenses. Picture from the network OTT, the so-called OTT, can be completely understood as the video service of the Internet company. From this point of view, it can be seen that OTT is a video service based on the public network. Mobile does not obtain an IPTV license, so it is only possible to develop TV services using OTT mode. . Advantages of mobile OTT set-top box: The content is relatively open, just like the current network box such as the millet box, Lynx box, etc., because it is based on the public network, so users can download the APP to watch their favorite content, of course, there are restrictions on the mobile set-top box That is, it will not let you download and install the tripartite app. Disadvantages of mobile OTT set-top boxes: Based on the public network transmission, it will occupy your actual bandwidth, and the switching platform will cache, and occasionally return to the card. Coupled with the restrictions on the three-party APP, so personal feeling is not as good as buying an ordinary network box to use. And more importantly, radio and television do not allow OTT live broadcast, so the TV on the mobile set-top box is strictly speaking not a live broadcast, because there is a delay, a relatively normal live broadcast to be delayed by about 3 minutes. This is not recommended for regular watching game broadcasts because you can't see live streaming. Of course, there are also a lot of live APPs that can be downloaded arbitrarily. There are no problems with hundreds of thousands of channels, but these are all delayed broadcasts. Once there was such a paragraph on the Internet, it probably meant that a rural area had finally moved through broadband before the New Year's Eve. Mobile sent a set-top box to ensure that users can watch the high-def Spring Gala on New Year's Eve. When a user watches TV at zero hour, waiting to go out and letting go of the fireworks, the results wait until the inside of the TV to report time when he goes out and finds silence around because the zero point has passed for several minutes. Picture from the network Finally, it is added that not only mobile is the OTT box. For example, China Unicom has obtained the IPTV license, but China Unicom does not operate IPTV in the South China region. The same OTT model is used. The Xiaobian is installed in Chengdu before Unicom broadband. The set-top box is also an OTT box. The live broadcast delay is 2 minutes, and the picture quality is very poor. It is simply not comparable to IPTV.
