Description

Streaming media server and system capable of randomly combining acquisition modules and implementation method

Technical Field

The invention relates to the technical field of audio and video signal transmission, in particular to a streaming media server, a server system and a system implementation method capable of randomly combining acquisition modules.

Background

The current streaming media server collects DVB signals and converts the DVB signals into network streams to a transcoder, the transcoder sends the audio/video signals to a content delivery platform (CDN), and the content delivery platform delivers the audio/video signals to terminal devices such as a mobile phone, an ott box, and a computer. The whole process comprises three main modules: a streaming server, a transcoder and a content delivery server (CDN).

Some of the current streaming media servers support signals of a DVB system, such as: some DVBS, DVBC or DVBT, etc. simultaneously support signals of multiple determined DVB systems, so that a client can only purchase one server according to a certain stage or a certain requirement of the client, and when the requirement changes, the server needs to be purchased again, which results in high cost, difficult construction and high maintenance cost.

Specifically, for example, some users need to support signals of two DVB systems: DVBT/C, some require one DVBS, and some require three DVBS/T/C; the number of each board may be different, and some customers only need one board to be the DVBS, the other three boards to be the DVBT, and one board to be the DVBC.

Therefore, there is a need to provide a streaming media server capable of freely combining the collection modules, so as to meet the requirements of all clients.

Preferably, each acquisition board card comprises an acquisition bottom plate, a one-to-two power divider arranged on the acquisition bottom plate, a plurality of tuners and a plurality of demodulators, wherein the number of the tuners and the number of the demodulators are consistent with that of the pluggable acquisition modules; the signal input end of the power divider is connected with an external signal socket, and the signal output end of the power divider is connected with the tuner.

Preferably, the number of the plurality of acquisition board cards is 5, and each acquisition board card is provided with 6 pluggable acquisition modules.

A can make up the flow media server system which gathers the die set at will, it includes: the streaming media server, the switch and the server mainboard of the acquisition module can be combined randomly; each acquisition module of the streaming media server converts acquired DVB signals into network streams, forwards the network streams to the server mainboard through the switch, and forwards the network streams to downstream equipment through the server built on the server mainboard.

Preferably, the number of switches is two, both gigabit switches.

A method for realizing the streaming media server capable of randomly combining the acquisition modules comprises the following steps:

configuring a plurality of acquisition board cards according to use requirements, and starting up the power supply;

the server mainboard acquires DVB (digital video broadcasting) modes of all acquisition modules on each acquisition board card and stores the DVB modes in a database;

a user accesses the Web, and the Web background acquires the DVB standard of each acquisition board card from the database;

judging whether the inserted acquisition board card is consistent with the previous acquisition board card;

if the judgment result is yes, continuously judging which DVB mode the inserted board card has; if not, deleting all the data stored in the database before the board card, and then continuously judging which DVB standard the inserted board card has;

if the judgment result is that the inserted board card is in a DVBS, DVBT or DVBC system, refreshing corresponding display, and configuring various satellite and frequency point lists in a database corresponding to the board card;

and the user respectively configures each acquisition board card to search and push the stream.

Compared with the prior art, the invention has the following advantages:

the server can be freely combined and randomly matched with the acquisition module, is provided with a plurality of board cards, can support any more or one of DVBS/T/C, is randomly matched in number, and can meet the requirements of different users; any use scenario may be accommodated.

Specifically, the streaming media server of the invention can freely combine the number of systems for collecting DVB signals, and can be one DVBS or DVBT, or three DVBS/T/C; the number of each acquisition module can be configured at will, so that the requirements of different users can be met, and the system is suitable for any use scene.

Detailed Description

The patent of the present invention is further illustrated by the following specific examples, which are not intended to limit the scope of the patent.

The first embodiment is as follows:

this embodiment provides a but combination wantonly gathers streaming media server of module, and it includes 5 collection integrated circuit boards 1, is equipped with 6 collection modules on every collection integrated circuit board 1, 30 collection modules altogether. The 5 acquisition board cards 1 can support different DVB systems, that is, the 5 acquisition board cards 1 can simultaneously support one of DVBs, DVBT and DVBC systems, or can respectively support two or three of the DVBs, and the number of the acquisition board cards 1 supporting each DVB system can be set at will (not greater than 5), so that various combinations can be formed according to the use requirements.
