System and method for introducing Internet video into cable television network for playing

Technical Field

The invention belongs to the technical field of cable television network video on demand service, and particularly relates to a system and a method for introducing an internet video into a cable television network for playing.

Background

With the continuous change of user demands and the rise of the internet in recent years, the dependence of users on the internet is deepened. Meanwhile, with the fire heat of the Internet television and the intelligent set top box, the networking of the cable television and the interaction of the television experience are shown to be a great trend in the future. With the basic completion of the digital translation work of the cable television and the deepening of the bidirectional network transformation work of the cable television network, the cable television network is expanded from a unidirectional transmission network to a comprehensive service network which can bear emerging service types such as IP data service, interactive video service and the like. Therefore, cable operators can introduce excellent services of the internet to expand their service layouts and meet the increasing demands of users, so as to gain the favor of users in intense market competition.

For internet general video services, the problems encountered when the internet is introduced into a cable television network are that the internet is different from an android set top box, the types of the television set top box are numerous, most of the traditional set top boxes do not support the HLS protocol of the internet video, and the set top box is difficult to modify and support the HLS protocol or is not feasible basically. In addition, with the continuous popularization of intelligent terminals, the requirements of users on terminal intellectualization are higher and higher, and updating and replacing an intelligent terminal supporting the HLS protocol is a good choice, but the cost is inevitably increased greatly. Therefore, when introducing video services of the internet, cable operators are often constrained by the performance of the set-top box, the cost of the set-top box, and the like, which brings great trouble to service introduction.

Disclosure of Invention

In order to introduce Internet video services into a cable television network, adapt to various types of traditional set top boxes, enable most of the traditional set top boxes to enjoy Internet video content services, reduce introduction cost and fully utilize the existing resources of the Internet, the technical scheme adopted by the invention is a method and a system for introducing Internet videos into the cable television network for playing.

Because general internet video playing is based on the HLS protocol and transmits video data through the IP network, the conventional set-top box does not support the HLS protocol and can only play video data transmitted based on the Cable network. The method adopted by the invention is to construct a conversion system which is added into the process of the video-on-demand of the cable television. The conversion system performs real-time protocol conversion on a video at the front end during each on-demand playing, converts video data transmitted by the Internet through an IP network channel based on an HLS protocol into video data pushed based on an udp protocol, then pushes the video data to the IPQAM, finally transmits the video data to the set top box through a Cable network channel, and the set top box performs frequency locking playing. The method can enable most of traditional cable television set-top boxes to play audio and video streams from the Internet without any adjustment, and achieves the purpose that the traditional set-top boxes quickly introduce Internet videos to play.
