The difference between OTT TV and IPTV

The difference between OTT TV and IPTV system is that many practitioners want to make it clear. Xiaobian sums up some of his own tests, and also organizes other related materials, hoping to help those in need: First, the individual understands the difference between OTT TV and IPTV system
what is OTT TV BOX technology

OTT TV and IPTV are differently defined by definitions, and are also influenced by human factors. From the perspective of the Zhengzhou SARFT, IPTV is a broadband operator that is qualified to operate. Its advantage is to take a private network, so the clarity of the live broadcast is better, the playback is smooth, and the carrier will not increase too More extra hardware costs, so for the operation, most operators use broadband to send IPTV boxes for free for the first year, and then charge an annual fee. In fact, the function of IPTV is to use live channels, such as CCTV and local TV. Of course, the IPTV in each province is somewhat different, and there will be some local local stations. For example, Shandong's IPTV TV box will have Jinan's main live broadcast channels (Qilu, Jinan TV, etc.).

Another advantage of IPTV is that it is back in 7 days. It is also an on-demand broadcast. It is only time-sensitive. In order to regulate the spread of market content, the non-operator companies can only operate OTT TV. The biggest one. The difference is that this kind of network TV directly uses the same network as the computer, so his on-demand resources are also synchronized with the network (IPTV will be less on-demand resources, and the update will be slower), and the resource richness and network are also In the same way, many OTT TVs have very close cooperation with the three major video websites, occupying the proportion of the business of the big screen. For example, Xiaomi can only pre-install the iQiyi TV, as long as the Xiaomi member is opened, the iqiyi vip is big. The screen is also free to watch. In addition, OTT's extended functions are also more abundant, and it can connect to third parties such as entertainment and shopping.

In general, OTT TV is richer in on-demand resources and more timely, and IPTV has the advantage of innate zehngce. In many users, it has become accustomed to watching live broadcasts using IPTV boxes, and watching them on-demand with OTT boxes. The situation should last for a while.

Two: OTT TV's past and present

1. What is OTT?

OTT is an abbreviation of “Over The Top”, which refers to providing various application services to users through the Internet. This kind of application is different from the communication service provided by the current operator. It only uses the operator's network, and the service is provided by a third party other than the operator. Currently, typical OTT services include Internet TV services, Apple App Store, and others.

 2, OTT TV is the abbreviation of "Over The Top TV", refers to the video service based on open Internet, the terminal can be TV, computer, set-top box, PAD, smart phone and so on. It means providing services on the network, emphasizing the independence of services from the physical network. The content of the video programs transmitted via the Internet, such as PPS, UUSEE, etc., is transmitted to the display screen (including the television).

From the consumer's point of view, OTT TV is an Internet TV that meets the needs of consumers and integrates full-featured Internet TV with interactive TV functions. For example, now more popular Xiaomi TV, Future TV, Galaxy Kiwi, Mango TV and so on.

The originator of the OTT business came from Skype. In the past, Skype invented the Internet phone, which allowed people to have free high-definition voice conversations with other users, as well as domestic and international calls. Later, Internet companies such as Google also followed suit and developed their free voice call services using the carrier's broadband network. In China, Skype has long been stopped by the Ministry of Information Industry, but Tencent’s WeChat has risen and appeared in the form of social services, but it is still a typical OTT business, because WeChat can realize free voice calls, and now many China If you go abroad, you can use WeChat to talk as soon as you can get free internet access. The reason is that you can avoid international roaming calls.

3, OTT TV three development models [1]

From a global perspective, there are three development models for OTT TV worldwide. The first is the HBBTV model that combines traditional broadcast and OTT services in Europe, and the second is the open OTT model based on the Internet architecture. The three are China's manageable and controllable models that emphasize content regulation.

1).HBBTV mode is the abbreviation of Hybrid Broadcast/Broadband TV. As a hybrid broadcast technology, it is an application function of a DVB-compatible content distribution platform. In addition to the most basic broadcast, HbbTV is used for networking services. There are VOD, time-shift TV, interactive advertising, online shopping and other applications.

2). The US open OTT model is represented by Google TV, Hulu, Netflix and iTV. Zeng Huiming, CEO of China Broadcasting Corporation, believes that the US OTT model is a view of open Internet services. Its core goal is to seek to interconnect home devices. Video services are no longer patents for broadcasting and television operators, telecom operators and the Internet. Enterprises, hardware vendors, and content producers all position themselves as participants in the video industry and gain value. In this process, in addition to PC terminals, OTT video services are gradually covering multiple terminals such as iPhone, iPad and Internet TV.

OTT (Over The Top), in the field of communications, refers to the provision of services including SMS, voice and even video by means of the operator's network services. In the TV field, OTT TV provides TV programs to users through the operator's network. Internationally, OTT TV transmits converged services such as IP video and Internet applications through various public network-oriented terminals (television, computers, tablets, smart phones, etc.).

Unlike traditional analog cable TV and classic digital TV, OTT TV and IPTV both transmit video content over IP networks, but IPTV and OTT TV still have essential differences in many aspects.

Third, the difference between OTT TV and IPTV system

In China, based on the national conditions and the influence of some policies, the difference between domestic OTT TV and IPTV is mainly reflected in the following points:

1, content provider

Due to policy restrictions, both IPTV and OTT TV are required to obtain relevant licenses issued by relevant departments.

Currently, IPTV content provider licenses include Shanghai Wenguang, CCTV International, Southern Media, and International Radio.

The content providers of OTT TV are Internet integration platform licensees, including Huashu, Bestcom, and Southern Media.

2. Business operators

The business operation of the IPTV service is undoubtedly the responsibility of operators such as China Unicom Mobile.

The service of the OTT TV service is provided by seven Internet integration platform licensees. After the user leases the broadband service of the operator, the OTT service will no longer bring other benefits to the telecom operator.

3, the network

The dissemination of IPTV TV content is based on a private network built by telecom operators. The initial investment is large, but the network bandwidth and video quality are guaranteed for users.

The spread of OTT TV is based on the ordinary public broadband Internet and requires a certain amount of bandwidth to guarantee the quality of video services. In the next few years, the optical network's substantial increase in broadband Internet bandwidth will largely guarantee the video quality of OTT TV and even HD OTT TV.

4, the terminal

The IPTV terminal collects STB+ ordinary home TV for operators. Since the IPTV set-top box is generally given by the operator when the user handles the service, the cost is low, and the IPTV private network needs to be coordinated, and the openness and operability are limited, and most of them are non-intelligent set-top boxes.

The terminal of OTT TV is OTT set-top box + display (television, computer, pad, mobile phone, etc.), and the set-top box can even be placed in the TV set. At present, the more popular mainstream set-top boxes are basically hardware manufacturers and seven licensees who have obtained licenses to launch smart set-top boxes with service and hardware binding.

5, video coding technology

IPTV video uses H.264 video coding technology.

OTT TV's video supports a variety of video encoding and decoding technologies based on terminal configurations such as set-top boxes. Relative to IPTV video, the bit rate is low and there is an adaptive function to keep the service uninterrupted in a poor network environment.

==================================================

IPTV is a video service carried out by telecom operators through IP private networks and dedicated IPTV set-top boxes. The display terminals are usually TV sets.

OTT TV is a video service carried out through the public Internet. The display terminal can be a personal computer or other display terminal such as a television or tablet.

OTT TV's service providers can be telecom operators, but also a variety of video sites and TV production facilities; therefore, OTT TV has multi-screen distribution, the natural advantage of multi-screen interaction

1, transmission: IPTV is the IP metropolitan area network, OTT is the Internet Internet

2. Content: IPTV is mainly the content of the licensee; OTT except the licensee content + video network content (with copyright) + other

3, the screen: IPTV is still only for the TV screen; OTT more Pad, Phone screen (so-called multi-screen interaction)

4. Business operators: IPTV is responsible for telecom operators, and OTT TV is an Internet integration platform licensee.

Others are more or less, mainly because the policy supervision is too strict, and it is felt that OTT and IPTV are different physical network transmission properties.
