Description
Technical Field
The invention belongs to the technical field of IPTV, and particularly relates to an IPTV soft terminal system based on automatic switching of multiple protocols of live broadcast services.
Background
Network television (Interactive Personality TV, IPTV) is a technology integrating internet, multimedia, communication and other technologies, and mainly presents content on a large screen through a set top box, so as to provide immersive video viewing experience for numerous home users. IPTV, unlike traditional analog cable television and digital television, adopts broadband network channels to transmit programs through IP protocol, and provides more interactive service functions, such as: on demand, live, review, time shift, etc. IPTV is also more diverse in terms of program selection and video quantity, and users can watch programs of live television stations, select on-demand resources and review missed programs. Meanwhile, the IPTV also has a bidirectional interaction function, so that a user can participate in the interaction discussion of the interested programs and can select the actively selected programs. In addition, IPTV uses a dedicated broadband network of an operator (telecommunications, communication, mobile), and adopts an independent networking mode to provide various interactive services including digital television.
However, as the popularization of intelligent televisions becomes a big trend, the performance of the intelligent television can completely replace the set top box, and the self-contained system of the intelligent television gradually preempts the first interface of the traditional IPTV set top box. The traditional IPTV operation mode based on the set top box has fallen to the trend of the times, and mainly has the following problems:
(1) IPTV hardware chip production constraints
The continuous improvement of the hardware cost of the set top box leads to the increase of the service development cost, and the problem of insufficient supply often occurs due to the production restriction of a hardware chip, and the old set top box is difficult to replace due to the cost problem;
(2) The hardware version is slowly upgraded in an iterative way, and the operation and maintenance support is insufficient
The existing network old and provider-withdrawn set top boxes cannot iterate due to maintenance-free support, novel applications such as 8K, VR and the like cannot bear, and the conventional hard set top boxes are upgraded with the problems of slow iteration of manufacturer versions and long period of existing network deployment and upgrading;
(3) Network environment is single
The IPTV is based on a set top box mode, a gateway iTV port is directly connected with the set top box, the set top box is directly connected with a television, and the IPTV live broadcast, the on-demand content and the like can be normally watched only in a wired mode, so that the installation environment is very limited;
(4) The barrier removal means is single in live-broadcast and blocking, and smooth recovery of user non-perception business cannot be realized
IPTV is based on the mode of a set top box, when problems such as live broadcast blocking and stream pulling failure occur, a fault report popup window occurs, and a user is required to contact operation and maintenance personnel for investigation. In this case, the user can only pause the viewing, and the master to be assembled can continue the viewing after the challenge is ended.
