Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention by being that each program transport streams distribute a uniform resource locator in video converter,
Then video playing is carried out by video player, can be realized and carries out video data broadcasting in Android system.
In order to illustrate technical solutions according to the invention, the following is a description of specific embodiments.
Fig. 1, which is shown, carries out video conversion method implementation by virtual server suitable for provided in an embodiment of the present invention
Network environment.Video converter is connect by Dongle (condition reception equipment) with television network broadcast, and broadcasting and television network is obtained
Audio/video program signal on network, i.e. transport stream, and played out on video player, optionally, video converter can also
Directly to be connect with television network broadcast.
In embodiments of the present invention, video player is the video playback apparatus for being installed on Android operation system, this sets
It is standby can also be by software realization in terminal Android operation system such as smart television and smart phone by hardware realization
The playout software of installation.
In embodiments of the present invention, video converter is the vision signal conversion equipment for being installed on Android operation system,
This equipment can also be realized that video converter can be placed in Web TV, can also be placed in by hardware realization by software
Network machine top box.
Video player and video converter can be located at the same hardware device, such as Web TV；It can also be located at not
Same hardware device, if video converter is located at network machine top box or Dongle, video player is located at Web TV.
As another embodiment of the present invention, video player can be to pass through wirelessly or non-wirelessly network and video converter
Connection receives virtual server in video converter and sends signal, and the equipment for being equipped with video jukebox software, such as：Mobile phone,
PAD or computer etc..
Video converter is Fig. 2 shows the implementation process of video conversion method provided in an embodiment of the present invention, and details are as follows：
In step s 201, multiplexed program transport stream is received, multiple single channel programs is converted by multiplexed program transport stream and passes
Defeated stream；
It in an embodiment of the invention, can be by video converter Dongle by received multifrequency point multiplexed program TS
Stream process is after single-frequency point multiplexed program TS flows, to pass through DVB (Digital Video in video converter
Broadcasting, digital video broadcasting system) standard modification be single channel program TS stream, the list is then sent by virtual server
Road program TS stream, can watch video in android system.
Since the TS stream that television network broadcast is transmitted to Dongle is the TS stream for including multiple frequency points, under each frequency point
TS stream contains multiple programs.Then it handles, multifrequency point TS stream is deleted only to specify frequency point comprising user through video converter
Polymera TS stream, and single-frequency point Polymera TS is streamed to video converter.
In video converter, received single-frequency point multiplexed program transport stream passes through DVB (Digital Video
Broadcasting, digital video broadcasting system) standard handled, is revised as single-frequency point single program transport stream, is transmitted to void
Quasi- server.
Video converter distributes a uniform resource locator in step S202, for each single program transport stream；
The source of media of the supported video playing of Android system has：What media file, file system in application program stored
Media file and external URL stream.Wherein, the media file in application program and file system is the media text for having size to limit
Part, this does not meet the requirement for playing TS stream；External URL stream is a data flow by network connection, is carrying out TS stream broadcasting
In the process, needing TS circulation turning to external URL stream could be in Android system normal play.
In embodiments of the present invention, a virtual server can be generated in video converter to be embodied as each single channel
Program transport streams distribute a uniform resource locator；The operating system of video converter is virtual server and TCP/IP
(Transmission Control Protocol/Internet Protocol transmits control/Internet protocol) protocol interaction mentions
Socket (Socket) interface is supplied.Virtual server passes through the IP (Internet of sockets interface and video converter
Protocol, Internet protocol) address binding, meanwhile, which is also the IP address in URL.At this time in video converter
A virtual server end is constructed, video player can access virtual server by URL.
Its Android video player and virtual server foundation are equivalent to C/S (Client/Server, client computer/service
Device) structure, Android video player accesses virtual server by URL.
In embodiments of the present invention, virtual server can be RTSP (Real Time Streaming Protocol, reality
When flow host-host protocol) server or HTTP (HTTP-Hypertext transfer protocol, hypertext transfer protocol)
Server etc..
In step S203, according to program playing request, by uniform resource locator by corresponding single channel program transmission
It spreads and is defeated by video player and plays out.
The single channel program TS stream that video converter transmits is sent to Android video player by virtual server, and by Android
The TS stream is decoded broadcasting by video player.
As an embodiment of the present invention, single-frequency point single channel program TS stream can be sent to video and turned by virtual server
Android video player in parallel operation plays out.
As another embodiment of the present invention, single-frequency point single channel program TS stream can also be sent to by virtual server to be passed through
Wirelessly or non-wirelessly network is connect with video converter, and the equipment for being equipped with video jukebox software, such as：Mobile phone, PAD or computer
Deng.
Fig. 3 shows the implementation process that virtual server provided in an embodiment of the present invention sends TS stream, and details are as follows：
In step S301, by the uniform resource locator, the connection request of at least one video playing is monitored；
Video player establishes connection request to virtual server broadcast transmission Discover message, at this time virtual clothes
Business device listens to connection request.
In step s 302, connection request is made a response, and at least one program for receiving video player transmission is broadcast
Put request；
In step S303, according to program playing request, corresponding single channel program TS stream is sent to video player.
Virtual server sends single channel program TS stream to video player respectively according to different playing requests.
Those of ordinary skill in the art will appreciate that：The step of realizing above method embodiment or part steps can pass through
The relevant hardware of program instruction is completed, and program above-mentioned can store in computer-readable storage medium, which exists
When execution, step including the steps of the foregoing method embodiments is executed, and storage medium above-mentioned includes：ROM, RAM, magnetic or disk
Etc. the various media that can store program code.
In embodiments of the present invention, by being that one unified resource of each program transport streams distribution is fixed in video converter
Position symbol, then carries out video playing by video player, reaches that it is not necessary to modify Android systems, both can local playback interface play
TS stream, can also mobile video terminal device play TS stream, reduce cost of implementation, allow user possess good play quality and
Internet experience.
