Description
Technical field
The present invention relates to a kind of network system applied technical field, the system and method that particularly a kind of Streaming Media is downloaded.
Background technology
Streaming Media is meant that data such as video, sound carry with RTP, and transmits to destination from the source end with the form of continuous stream, receives the multimedia application that certain data cached back just can play back at destination.
Streaming Media is the address to the time base continuous media that can transmit as a stream.Continuous media itself has the advantages that partial data just can be play.3GPP standard " 3GPP TS 26.244 " all has clearly definition to the file format and the coded format of Streaming Media, and files in stream media can be play in this locality.
The Streaming Media basic service can be divided into following three kinds of typical traffic pattern:
1, streaming media on demand (VOD)
Streaming media on demand is that the content of multimedia encoding compression that content supplier will prerecord becomes corresponding format, leave on the content server and and be placed in the portal website of Streaming Media the descriptor of content and link, find interested content by the terminal use, play selectively.
2, live streaming media
Live streaming media is that the Streaming Media encoder server becomes corresponding form with the live signal encoding compression, and is distributed to user's terminal player via streaming media server.According to the difference of real time content signal source, can be divided into live telecast, remote monitoring etc. again.
3, downloading and playing
Downloading and playing is that the user downloads streaming medium content and store in the local terminal, can be chosen in random time then and play.For the local file playback, main restriction index is the disposal ability of terminal and the storage capacity of terminal, content supplier can produce the video content (high bandwidth, high frame rate) of better quality, but will consider the download time of content and the memory space of terminal.
Download is that complete media content is sent to mobile device terminal from the download service system.Compare with stream mode, could play owing to media content need be downloaded to mobile device terminal fully, the user need wait for the long period.Stream mode is higher to requirements for transmission, if the encoded bandwidth of media content is higher than transmission bandwidth, and then can not normal play.
Downloading mode is less demanding to bandwidth.If transmission bandwidth is lower, period of reservation of number is long slightly.Usually provide the download load mode to the higher medium of encoded bandwidth, therefore download the effect of the result of broadcast comparison type broadcast of back medium and will get well.And after downloading, media content has been kept at mobile device terminal, and the time place that the user can select arbitrarily oneself to like is watched, and can not be subjected to the influence of network environment.
May be in the downloading process owing to mobile device terminal, medium can not download to mobile device terminal fully, and perhaps medium can not be play after downloading.If relate to charging problem, the download service system might occur and think that success downloads, mobile device terminal is then thought and the situation that not have download to finish for above problem, is adopted method and system provided by the invention to solve.
Summary of the invention
