Abstract
The invention relates to a method for mobile stream media lively broadcasting quasi real-time stream. The generated media file is multi-bit rate file that every media type in file has multi-bit rate data, and every data block contains data of different media type and all needed bit rate; the method comprises: step 110, user terminal sends request for quasi real-time stream to downloading server, the request indicating transmission bit rate the terminal needed; step 120, downloading server extracts all media type data with user terminal needed bit rate in current data block of multiple bit rate file, reconstructs a media file data block with standard format, then transmits to user terminal. The inventive method can make user accessing to different network to enjoy the transmission speed.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method of live broadcasting quasi-real-time stream by mobile stream media.
Background technology
Along with the construction of 3G network, mobile flow medium service more and more is subjected to telecom operators and users' attention and welcome.But telecom operators also will take into account the problem that the user who considers the 2.5G network uses mobile flow medium usually when building mobile stream media system.3G network is different on message transmission rate with the 2.5G network, and gap is bigger.
The user is when using the quasi real time stream of watching programme televised live while downloading professional, because the network difference that the user inserts, the speed difference of wireless transmission causes the demand difference of user to the bit rate of program transmission.For example CDMA2000 1xEVDO user is different because of wireless transmission speed with CDMA2000 1X user, when watching same program, if carry out the transmission of programme content according to a transmission speed, will cause certain customers satisfied and another part user dissatisfied.If carry out the transmission of programme content according to the transmission speed of CDMA2000 1xEVDO, because the restriction of wireless transmission bandwidth will cause a large amount of message droppings, it is bad the mosaic user experience to occur for CDMA20001X user.If carry out the transmission of programme content according to the transmission speed of CDMA2000 1X, for CDMA2000 1xEVDO user, its wireless network bandwidth can cause an idle part, the frame per second of image, bit rate all can only adapt to the transmission speed of CDMA2000 1X, and can not get better user experience.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of bit rate system of selection of live broadcasting quasi-real-time stream by mobile stream media is provided, and makes the user who inserts heterogeneous networks can both obtain satisfied transmission rate.
For addressing the above problem, the present invention proposes a kind of method of live broadcasting quasi-real-time stream by mobile stream media, it is characterized in that, the media file that live broadcasting quasi-real-time stream by mobile stream media generated is the multiple bit rate file, be that every kind of medium type has the data of multiple bit rate in the file, and comprise the data of bit rate of all requirements of different media types in each data block; The method of described live broadcasting quasi-real-time stream by mobile stream media comprises following steps:
Step 110, user terminal sends quasi real time stream request to Download Server, indicates the transmission bit rate of this demanding terminal in the request;
Step 120, Download Server comes out the data pick-up of all medium types of the bit rate of user terminal requirement in the multiple bit rate file current data block, re-constructs into the media file data piece of a reference format, sends to user terminal.
Further, said method also can have following characteristics, and each bit rate in the described multiple bit rate is corresponding to a kind of wireless transmission bandwidth of network, and the user selects the bit rate of corresponding transmission program according to employed network.
Further, said method also can have following characteristics, and the media file that described live broadcasting quasi-real-time stream by mobile stream media generated is kept in the Download Server.
Further, said method also can have following characteristics, and the request of described quasi real time stream is for watching the quasi real time stream request of programme televised live while downloading.
Adopt method of the present invention can make the user who inserts heterogeneous networks can both obtain satisfied transmission rate.
Description of drawings
Fig. 1 is the interacting message schematic diagram of embodiment of the invention method.
Fig. 2 is the schematic diagram of data pick-up reconstruct in the described embodiment method of Fig. 1.
Embodiment
At first, the media file that live broadcasting quasi-real-time stream by mobile stream media generated must be the multiple bit rate file, and promptly every kind of medium type has the data of multiple bit rate in the file, and comprises the data of bit rate of all requirements of different media types in each data block.Quasi real time flow the multiple bit rate file that is generated and be kept in the Download Server, each bit rate in the multiple bit rate is corresponding to a kind of wireless transmission bandwidth of network, and the user selects the bit rate of corresponding transmission program according to employed network.
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
Please refer to Fig. 1 and Fig. 2, the method that present embodiment indicates the bit rate of Download Server transmission program may further comprise the steps:
User terminal sends the quasi real time stream request of watching programme televised live while downloading to Download Server, and having indicated in the request and having required the bit rate of Download Server transmission program is 64kbps;
After Download Server is received described quasi real time stream request, know that user terminal wishes to use the programme content of bit rate as 64kbps;
Download Server is at the current data block in the multiple bit rate program file, and the data pick-up of all medium types of the 64kbps bit rate that user terminal is wherein wished comes out;
The data of all medium types that Download Server will extract re-construct into the form of the media file data piece of a standard, send to user terminal;
Then begin programme content to user terminal transmission 64kbps bit rate.
User terminal has obtained the programme content of own desirable transmission rate
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
Claims (4)
1, a kind of method of live broadcasting quasi-real-time stream by mobile stream media, it is characterized in that, the media file that live broadcasting quasi-real-time stream by mobile stream media generated is the multiple bit rate file, be that every kind of medium type has the data of multiple bit rate in the file, and comprise the data of bit rate of all requirements of different media types in each data block; The method of described live broadcasting quasi-real-time stream by mobile stream media comprises following steps:
Step 110, user terminal sends quasi real time stream request to Download Server, indicates the transmission bit rate of this demanding terminal in the request;
Step 120, Download Server comes out the data pick-up of all medium types of the bit rate of user terminal requirement in the multiple bit rate file current data block, re-constructs into the media file data piece of a reference format, sends to user terminal.
