Below by drawings and Examples, technical scheme of the present invention is described in further detail.
A kind of VOD method first embodiment of the present invention
As shown in Figure 1, be the flow chart of a kind of VOD method first embodiment of the present invention, this VOD method specifically comprises as follows:
At present, the media formats of terminal support has multiple, as dynamic image MPEG-2 (MovingPictures Experts Group-2 is designated hereinafter simply as MPEG-2), H.264 wait; And the network of terminal support also has multiple, as cable (Cable) network and Internet protocol (InternetProtocol is designated hereinafter simply as IP) network.
A kind of VOD method first embodiment of the present invention, terminal is by selecting program and generating the mode of terminal requirements information from the electronic program list with related information, the electronic program list that makes terminal receive is succinct, overcome the defective that has a plurality of identical media contents in the electronic program list that terminal receives in the prior art, promptly overcome electronic program list and showed complicated defective.And the TV electronic program list that is generated has also been considered the attribute of terminal, therefore the brief introduction that can improve electronic program list further, be specially: if the media formats of supporting based on related information and terminal generates electronic program list, then can prevent has terminal not occur by display media content in the electronic program list that terminal receives; If the network plutonic electronic program list that media formats of supporting based on related information, terminal and terminal are supported, though terminal is supported this media formats in the electronic program list that then can terminal receives, the media content that terminal can not receive occurs.
In a kind of VOD method first embodiment of the present invention, further comprise: receive the program address of network side according to the available situation generation of terminal requirements information and described terminal attribute, related information and network; And obtain corresponding program according to described program address.The available situation of network specifically is meant the load of network or the ability of network support media formats, when generating program address (as URL(uniform resource locator) etc.), if specifically considered the loading condition of network, prevented that then the big network of load from continuing the carrying VOD service, if specifically considered the ability of network support media formats, then under identical network condition, can generate the higher program address of quality, the higher media formats of program address correspondence image quality that promptly generates, thereby can improve the display quality of the media content that terminal receives, if considered the ability of network load condition and network support media formats simultaneously, both can prevent then that the big network of load capacity from continuing bearer service, can improve the display quality of the media content that terminal receives again, thereby effectively managed the service bearer amount between the heterogeneous networks, thereby improved network operation efficient.
In a kind of VOD method first embodiment of the present invention, may further include:, provide service by corresponding TV programme module to the network side request according to the display capabilities of terminal; And receive the TV programme module information that is complementary with the terminal display capabilities according to this request.Like this, in subsequent operation, terminal provides service according to this TV programme module information to this TV programme module request.And the entity in this service request of network side receiving terminal is specially TV programme scheduler (EPG Distribute System, be designated hereinafter simply as EDS), be that terminal provides service to the EDS request, and the corresponding TV programme module information of reception and terminal display capabilities, wherein display capabilities includes resolution, the picture format that can show or the media formats that can show etc.; Login described EPG according to terminal attribute, wherein terminal attribute includes the network of terminal support and the media formats that terminal is supported.Like this, can be by receiving the EPG information that sends by EDS, terminal display capabilities and EPG were mated, and login the method for this EPG according to this terminal attribute, the defective of the service that terminal is not supported EPG and provided has been provided, make terminal to realize VOD service, thereby further improved resource utilization according to resolution capability.
Another kind of VOD method first embodiment of the present invention
Fig. 2 is the flow chart of another kind of VOD method first embodiment of the present invention, and this VOD method specifically comprises:
Table 1
In addition based on media formats, the program address of offered load and terminal requirements information (as the URL of program), the generation method is specially: based on institute's attribute information of terminal, all media formats of supporting as terminal, BMS obtains the media formats that terminal can receive from related information, be about to get common factor between the media formats of media formats corresponding and terminal support with media content, generate the media formats that terminal can receive, media formats and the loading condition of current network and the ability of network support media formats that can receive then according to terminal, judge with which network carrying business, and generate corresponding program address (as URL etc.) according to this judged result; The ability of network support media formats just is meant between specific media format and the particular network and has compatibility relation, if media formats is respectively MPEG-2 and H.264, the network that is used for bearer service is respectively cable system and IP network, compatibility relation between then above-mentioned specific media format and the particular network is as shown in table 1 below, and table 2 has been represented compatibility relation between media formats and the network.
Table 2
Here, if loading condition Network Based generates program address, can prevent that then the bigger network of load from continuing the carrying video traffic, if the ability of support media form Network Based generates program address, then can under the identical network condition, can improve the display effect of media content, if the ability of loading condition Network Based and network support media formats generates program address, then consider offered load and display effect simultaneously.In fact, can generate two or more program address at a demand information according to concrete algorithm with after the situation through weighting network.
Another kind of VOD method first embodiment of the present invention, by media content and media formats being carried out method related and that send, make the TV programme module can generate electronic program list with related information, thereby overcome the defective that repeats to show media content in the electronic program list of prior art generation with different media formats, and by BMS according to the current network loading condition, dynamically generate the method for URL, realized the dynamic dispatching network, therefore can prevent that the big network of load capacity from continuing the carrying VOD service, thereby overcome the inefficient defective of prior art network operation, improve the network service efficiency effectively, can also improve the quality of terminal receiving video service simultaneously.
Another kind of VOD method first embodiment of the present invention, can further include: BMS notice video request program device (VOD) media content download, BMS carries out related with media formats described media content then, generate related information, content provider (Content Provider) oneself sets up a FTP (File Transfer Protocol) for the VOD media content download in general, then by BMS notice VOD media content download.Further, can pass through Content Management System (Content Management System before the VOD media content download, be designated hereinafter simply as CMS) revise the relevant information of media content, as the title of media content, the author of media content, the brief introduction of media content etc.Like this can enrich the content of showing in the electronic program list by follow-up further operation.
