[0091] The present invention is a radio and television OTT fusion terminal, which can switch the network environment of the internal network / external network at any time, and achieve self-adaptation; in the internal network environment of the broadcasting and television operator, the live broadcast program is received through the RTP multicast protocol supported by the set-top box for video playback ;In the external network environment, the live broadcast program is received through the supported Live Smooth stream / HLS protocol for video playback. Time shifting, playback, and on-demand other video content, both internal and external, are all performed through the Live Smooth stream / HLS protocol supported by the set-top box. The main components of the fusion terminal of the present invention include: video ASI signal source, video ASI signal to IP signal transcoding equipment, video format MPEG2 to H.264 encoding equipment, live multicast server, live time-shifted Live Smooth st...

Embodiment 2

[0107] This embodiment introduces each working process of a method for implementing a radio and television OTT fusion terminal according to the present invention.

[0108] (1) Live broadcast on the radio and television intranet through the working method of multicast broadcasting

[0109] Intranet live broadcast adopts RTP protocol for multicast distribution, and transmits through optical fiber / coaxial cable / category 5 line, etc. When the set-top box authenticated by the intranet authentication server initiates a live multicast request, for example, after sending a multicast request of "rtp: / / *.*.*.*:*", the live multicast server performs a multicast access request. Under the CMTS network, the live multicast server has the following special requirements for the Cable Modem:

[0110] (1) Cable Modem needs to have built-in lineup.xml.

[0111] lineup.xml describes the correspondence between multicast addresses and frequencies. When the set-top box has a multicast request, Cabl...

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; Transformation function as one) or IP way to achieve interactive business, the interaction 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 the new business, the business scalability is poor; the...
