For reaching above-mentioned purpose, the present invention has adopted following technical scheme to realize: a kind of online player method of digital television program, and it comprises step:
The user of digital-television terminal equipment selects to watch the link of program, sends access request by the internet to streaming media server;
Streaming media server is packaged into a plurality of packets with the stream medium data of the corresponding program of this access request;
Digital-television terminal equipment creates the packet of downloading task download stream media data, and carries out playback process by the decoder of setting this stream medium data of decoding.
Wherein, digital-television terminal equipment is with P2P mode or HTTP mode download stream media data.
Wherein, digital-television terminal equipment is preserved file with the download that the stream medium data of downloading is kept on hard disk.
Wherein, digital-television terminal equipment is that URL by program chaining sends access request to streaming media server.
Wherein, digital-television terminal equipment manual search or acquiescence address searching mode enter streaming media server searching streaming media content.
Wherein, if select the manual search mode, according to the keyword search streaming media server content of user in the digital-television terminal equipment input, and streaming media server is back to digital-television terminal equipment with Search Results.
Wherein, if select acquiescence address searching mode, streaming media server is shown to digital-television terminal equipment with whole categorised content links.
Wherein, streaming media server judges is from the access request of digital-television terminal equipment, judges for the authority of access request whether this access request is effective.
Compared with prior art, the present invention has following beneficial effect:
Due to the present invention be by digital-television terminal equipment by P2P technology or HTTP technology from internet download stream media data, Internet-based network speed of download can be very fast, can satisfy the bandwidth demand of online playing stream media TV programme fully, realize playing online TV programme according to user's needs on digital-television terminal equipment.Therefore, the present invention watches program only need to use the Internet, particularly the Internet has spread to average family now, can realize simultaneously that Web TV watches and other network functions, avoided the user must wait for the shortcoming that whole file all just can be watched from the internet download, enriched the function of digital-television terminal equipment, and make the user can free select time and program watch.
Description of drawings
Fig. 1 is connection diagram of the present invention;
Fig. 2 is schematic flow sheet of the present invention.
Embodiment
The present invention is disclosed on digital TV terminal by internet use stream media technology accesses network media program resource, realize watching online program and downloading while watching on the P2P stream media technology, solve the time restriction of television-viewing program and to the washability of program, allow TV programme adapt to the user, make the user can free select time and program watch.
As shown in Figure 1, digital-television terminal equipment 1 utilizes the network access equipment accessing Internet networks such as router and switch, and with URL (Uniform Resource Locator, URL(uniform resource locator) or webpage network address) mode accesses the streaming media server 2 in the internet, obtains the flow-medium performance resource that can play.Streaming media server 2 is after the access request that receives digital-television terminal equipment 1, the streaming media resource link that can provide is provided by authority, the program that the user elects and likes in digital-television terminal equipment 1 drilling attaches to streaming media server 2 by the streaming media resource chain that returns and carries out the program location; Streaming media server 2 sends the user in the mode of packet and selects stream medium data corresponding to program to digital-television terminal equipment 1, the player plays program that digital-television terminal equipment 1 sets in use.
In general, digital-television terminal equipment 1 is the IP set-top box, can access the IPVT network by IP mode or Ethernet mode, and will convert by the information such as Media Stream that Internet Transmission is come simulation to and look audio frequency and export the television set that is connected with digital-television terminal equipment 1 to.
In conjunction with shown in Figure 2.The present invention realizes comprising in the processing procedure of streaming media playing at digital-television terminal equipment:
Step S1: with digital-television terminal equipment accessing Internet network.This function mainly relies on the Internet to realize whether digital-television terminal equipment and streaming media server can be completed normal communication and judge.Network connects and can judge according to the interconnection network kind of family, and present network uses kind many, and the present invention is applicable to multiple network.
Step S2: the mode of selecting to enter streaming media server searching streaming media content is manual search or gives tacit consent to address searching.This is similar with the pc access web film, and a kind of is can be according to all the elements of streaming media server demonstrations of classifying, and selects to segment program entering into corresponding classification, and the server access URL of this mode is for arranging; Also having a kind of access mode is manual search, can input keyword with input method, from key combination URL access stream media server.
Step S3: if select the manual search mode, according to the keyword search streaming media server content of user in the digital-television terminal equipment input.
Step S4: streaming media server is back to digital-television terminal equipment with Search Results.This Search Results is not real flow-medium performance, but some programm names of streaming medium content, introduce in detail, be the link URL of each program in addition.
Step S5: if select acquiescence address searching mode, streaming media server is shown to digital-television terminal equipment with whole categorised content links.
Step S6: the user of digital-television terminal equipment selects the program chaining like by the streaming media server returned content, and the URL access request by program chaining is to streaming media server.
Step S7: streaming media server judges is from the access request of digital-television terminal equipment, judges for the authority of access request whether this access request is effective.
Step S8: if access request is effective, streaming media server program data compression packing corresponding to this access request, being divided into a lot of packets, is convenient to send to digital-television terminal equipment take packet as unit by the internet.
Step S9: digital-television terminal equipment creates downloading task, utilizes P2P download or HTTP downloading mode from streaming media server downloading data bag, creates on the acquiescence hard disk simultaneously and downloads the preservation file to preserve the packet of this program.
Step S10: after streaming media server sent bag, digital-television terminal equipment need to cushion several seconds and start time-delay, and by the stream medium data that player is decoded and processed, namely exportable program video and audio frequency to television set is watched.After program begins to play, the stream medium data of program remainder will continue to download from streaming media server on the backstage, download simultaneously the program of watching, the stream media technology transmission has avoided the user must wait for that whole file is all from the complete shortcoming that just can watch of streaming media server download.
