Problems solved by technology

For example, due to the different wireless transmission speeds between CDMA2000 1xEVDO users and CDMA2000 1X users, when watching the same program, if the content of the program is transmitted at a transmission speed, some users will be satisfied while others will be dissatisfied
If the program content is transmitted at the transmission speed of CDMA2000 1xEVDO, for CDMA20001X users, due to the limitation of wireless transmission bandwidth, a large number of messages will be lost, and mosaic will appear, which is not good for user experience
If the program content is transmitted at the transmission speed of CDMA2000 1X, for CDMA2000 1xEVDO users, the wireless network bandwidth will be idle, and the frame rate and bit rate of the image can only adapt to the transmission speed of CDMA2000 1X, but cannot get better user experience

Embodiment Construction

[0014] First of all, the media files generated by quasi-real-time streaming of mobile streaming media must be multi-bit rate files, that is, each media type in the file has data of multiple bit rates, and each data block contains all required data of different media types bit rate data. The multi-bit rate files generated by the quasi-real-time stream are stored in the download server. Each of the various bit rates corresponds to the wireless transmission bandwidth of a network, and the user selects the corresponding transmission program according to the network used. bit rate.

[0015] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0016] Please refer to figure 1 with figure 2 , the present embodiment indicates that the method for downloading the bit rate of the program transmitted by the server includes the following steps:

[0017] The user terminal sends a quasi-real-time streamin...

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 [0001] The invention relates to the communication field, in particular to a method for live quasi-real-time streaming of mobile streaming media. Background technique [0002] With the construction of 3G network, the mobile streaming media service is more and more valued and welcomed by telecom operators and users. However, when telecom operators build mobile streaming systems, they usually have to take into account the use of mobile streaming by users of 2.5G networks. 3G network and 2.5G network are different in data transmission rate, and the gap is large. [0003] When users use the quasi-real-time streaming service of watching live programs while downloading, because the networks the users access are different, the wireless transmission speeds are different, resulting in different user requirements for the bit rate of program transmission. For example, CDMA2000 1xEVDO users and CDMA2000 1X users have different wireless transmission speeds. When watching...
