Description
Technical Field
The invention belongs to the field of computer networks, and particularly relates to a method and a device for distributing Internet live streaming and computing equipment.
Background
The fusion media is also called media fusion or fusion media, and includes narrow media fusion and broad media fusion, the narrow media fusion refers to that different media forms are "fused" together, and then "qualitative change" is generated, so as to form a new media form, such as electronic magazine, blog news, etc.; the broad media fusion is broad in scope, including the combination, aggregation and even fusion of all media and related elements, including not only the fusion of media forms, but also the fusion of media functions, propagation means, ownership, organization structures and other elements. In other words, "media fusion" is a new operation mode under diversification of information transmission channels, and is to effectively combine traditional media such as newspapers, television stations, radio stations and the like with a propagation channel of emerging media of intelligent mobile terminals such as the internet, smart phones, tablet computers and the like, share resources, and perform centralized processing to derive information products of different forms.
In the era of integrated media, media units promote the integration of self-generated internal resources and integrate the internet acquisition and propagation channel of contents. The transmission of the live broadcast signal is an important form of content transmission, and as the concept of the fusion media is deepened, a fusion media reporter can explore news values anytime and anywhere and accelerate the transmission speed of the news, so that professional rebroadcasting equipment is abandoned, the rapid internet distribution is introduced to become a necessary working method for the fusion media reporter, and in a transmission channel, an internet channel, a television channel, a cable network or an IPTV (Internet protocol television) private network channel are all important transmission ways.
However, the existing distribution scheme of the internet live stream has the following problems: when the converged media reporter is live broadcast (including local and remote live broadcast) on the internet, the converged media reporter can only accelerate the broadcast in a new media channel through a Content Delivery Network (CDN), and a traditional channel, such as a television channel, cannot acquire signals, but because operator networks are private networks, the converged media reporter cannot broadcast in a private Network channel. In other words, the existing distribution scheme of internet live streaming still has the problem that the media cannot share and communicate with each other, and is not in accordance with the original intention of merging the media.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is a schematic flow chart of an implementation process of a distribution method of internet live streaming provided by an embodiment of the present invention, which mainly includes the following steps S101 to S104, and the following detailed description:
s101, according to live broadcast performed by the terminal, the scheduling center generates a live broadcast address of the internet live broadcast stream.
Since the existing smart phone has a video recording function, in the embodiment of the present invention, the terminal may be a mobile terminal such as a smart phone, or some electronic devices with a video recording function, such as a video recorder, which is not limited in this respect. When the terminal is in live broadcasting, live broadcasting content can be transmitted to the scheduling center in a form of live broadcasting stream (stream) through a Real Time Message Protocol (RTMP). In the embodiment of the present invention, the scheduling center and the forwarding server may be the same physical device located at the internet end, for example, one server having the scheduling function and the forwarding function, or two servers which may be interactive and respectively have the scheduling function and the forwarding function.
As an embodiment of the present invention, according to the live broadcast performed by the terminal, the generation of the internet live broadcast stream by the scheduling center may be: the method comprises the steps that a scheduling center receives a live stream transmitted by a terminal, the scheduling center generates a live broadcast address of the internet live stream according to a live stream internet domain name and the live stream, and the terminal pushes the internet live stream to a Content Delivery Network (CDN) according to the live broadcast address of the internet live stream. For example, if the live stream of the terminal for live broadcasting is represented by live/StreamName, and the internet domain name of the live stream is live.
And S102, under the scheduling of the scheduling center, the forwarding server pulls the Internet live stream according to the live address of the Internet live stream.
In the embodiment of the invention, after the scheduling center generates the live broadcast address of the Internet live broadcast stream, the scheduling center is automatically triggered to issue the distribution command to the forwarding server, and the distribution command comprises the live broadcast address of the Internet live broadcast stream. As described above, the terminal has already pushed the internet live stream to the CDN according to the live address of the internet live stream. Therefore, when the forwarding server receives the distribution command issued by the scheduling center, the forwarding server pulls the internet live stream from the CDN according to the live address of the internet live stream. It should be noted that the internet live stream pulled by the forwarding server from the CDN is actually distributed by the CDN according to the internet live stream pushed by the terminal. Because different CDN anti-theft chain rules can be realized in the scheduling center, the forwarding server can pull a plurality of live stream addresses containing CDN anti-theft chains, and therefore the addresses of the internet live streams pulled by the forwarding server from the CDN are also the addresses containing the anti-theft chains calculated by the scheduling center in a statistical manner.
S103, under the scheduling of the scheduling center, the video production system in the television station pulls the Internet live stream from the forwarding server to generate a television signal for playing.
As an embodiment of the present invention, under the scheduling of the scheduling center, the video production system in the television station pulls the internet live stream from the forwarding server to generate the television signal for playing may be completed by the following steps S1031 to S1033:
and S1031, the video production system in the television station receives the stream pulling decoding command and the switching command transmitted by the dispatching center.
S1032, according to the stream pulling decoding command issued by the dispatching center, a decoder of the video production system in the television station pulls the Internet live stream from the forwarding server and decodes the Internet live stream to obtain the serial digital interface SDI signal.
As described above, the forwarding server has pulled the live internet stream from the CDN according to the live broadcast address of the live internet stream, so that after receiving the stream pulling decoding command issued by the scheduling center, the decoder of the video production system in the television station can pull the live internet stream from the forwarding server and decode the live internet stream to obtain the serial digital interface SDI signal. It should be noted that the forwarding server is internally provided with a broadcast anti-theft chain, so that it can be ensured that the internet live stream pulled by the decoder of the video production system in the television station from the forwarding server is an effective and legal internet live stream.
And S1033, outputting the SDI signal decoded by the decoder to a master control room or a studio by a serial signal interface matrix of a video production system in the television station according to the switching command issued by the dispatching center.
And S104, the forwarding server pushes the Internet live stream to a private network according to the requirement.
The forwarding server has pulled the internet live stream, via step S102. The forwarding server may push the live internet stream to a private network, such as a private cable television network or a private IPTV network, as needed. Specifically, The forwarding server may actively push an internet live stream to an intranet streaming media server of a private network in an RTMP mode as required, and then The intranet streaming media server transmits The internet live stream to an Over The Top (OTT) device of The private network, for example, a set Top box, and The Over The Top (OTT) device plays The internet live stream.
It should be noted that, although the internet live stream is broadcast in different channels (internet, video production systems in television stations, and private networks), the signal stream is distributed and broadcast in the whole network integrally by domain name binding in view of the uniqueness of the name or ID of the internet live stream.
In addition to pulling the internet live stream from the forwarding server, the private network such as the cable television private network or the IPTV private network may also directly send the source stream of the internet live stream to the private network, that is, the scheduling center directly sends the source stream to the private network without pulling the internet live stream from the forwarding server. For example, assuming that the source stream name issued by the scheduling center to the private network is live/StreamName, the OTT device in the private network reassembles the live address of the source stream according to its domain name and the anti-stealing chain rule, e.g., live. the OTT device in the private network can live this stream, and the timestamp & Sign is a signature. Similar to the source stream that the scheduling center can directly send the internet live stream to the private network, the scheduling center can also send the source stream of the internet live stream to the internet terminal, for example, assuming that the source stream name that the scheduling center issues to the internet terminal is live/StreamName, the internet terminal reassembles the live address of the source stream according to its domain name and the anti-stealing chain rule, for example, live. the time stamp & Sign is a signature, and the internet terminal can play this stream.
As can be known from the distribution method of the internet live stream illustrated in fig. 1, since the internet live stream always exists on the internet, the internet live stream can be transmitted on the internet, on the other hand, under the scheduling of the scheduling center, the video production system in the television station pulls the internet live stream from the forwarding server to generate a television signal for playing, and the forwarding server can also push the internet live stream to the private network.
