A radio and television ott fusion terminal and its implementation method

Abstract

The invention discloses a broadcasting and TV OTT (over the top) integration terminal and an implementing method thereof. The terminal comprises a video ASI signal source, a DCM transcoder, a video coder, a multicast live streaming server, a Live Smooth stream / HLS (HTTP live streaming) server and a set top box. The terminal integrates the RTP multicast technology and the Live Smooth stream / HLS technology, has abundant high-definition broadcasting and TV live streaming resources and is high and stable in video quality; the set top box can automatically distinguish network environments, play high-definition live streaming signals based on RTP multicast in an inner broadcasting and TV network and automatically and selectively play Live Smooth stream / HLS code streams capable of being adapted to the network environments in an outer broadcasting and TV network, live streaming services can be enjoyed nationwide, and the application range is not limited by regions. The terminal can be widely applied to the video field.

Description

technical field [0001] The invention relates to the field of video, in particular to a radio and TV OTT fusion terminal and an implementation method thereof. Background technique [0002] At present, the mainstream products of video service terminals are divided into: DVB, OTT, IPTV, DVB+OTT according to technology. The characteristics of various products are as follows: [0003] 1. DVB (Digital Video Broadcasting): Traditional radio and television technology, rich in frequency resources but lacking in video content, guaranteed bandwidth, and good channel quality; through IPQAM (a type of modulation equipment, multiplexing, scrambling, modulation, Transformation functions as a whole) or IP way to realize interactive business, the interactivity is weak; generally use linux system, set-top box bottom driver + middleware to realize software functions, business expansion must be specially customized and developed software for this system, mostly through OTA ( OTA technology) i...

AI Technical Summary

Problems solved by technology

[0003] 1. DVB (Digital Video Broadcasting): Traditional radio and television technology, rich in frequency resources but lacking in video content, guaranteed bandwidth, and good channel quality; through IPQAM (a type of modulation equipment, multiplexing, scrambling, modulation, Transformation functions as a whole) or IP way to realize interactive business, the interactivity is weak; generally use linux system, set-top box bottom driver + middleware to realize software functions, business expansion must be specially customized and developed software for this system, mostly through OTA ( Over the air download technology) upgrade to complete new services, business scalability is poor; the scope of application is limited by the region, only users within the scope of the radio and television network can enjoy the video services it provides

[0004] 2. IPTV (Interactive Internet TV): Mainly used in the scope of telecom operators, the video quality is poor and unstable, the promotion is restricted by policies, and the live broadcast resources are insufficient; the Linux system is generally used, and business expansion requires custom development, and the business scalability is relatively low. Poor; transmission via all-IP

[0005] 3. OTT (Internet TV): A newly launched Internet video service terminal, with rich video content but poor video quality, a wide range of applications, and can provide users with independent video services; using the Android system, the business scalability is very good; but Due to the impact of the policy, it has no legal live TV resource service at all

[0007] To sum up, the current video service terminal products in the industry cannot simultaneously meet the requirements of rich live broadcast resources, high video quality, stability, and application scope without geographical restrictions
