Description
Technical field
The present invention relates to a kind of call method, particularly, be a kind of be carrier with TV, network, mobile phone and display, be the call method of user's audio plays, video content.
Background technology
Along with the continuous development of science and technology, audio frequency, Video service are also in continuous upgrading, and we can be in and come channel selection to watch audio-video frequency content by remote controller; Can be connected with computer by network and more see audio-video frequency content, can receive audio-video frequency content by the value-added service of mobile phone.
But, be in and have TV in arms and constantly change this traditional watching mode of TV programme and can not be accepted by people already.Because TV programme all is to record in advance, along with different time sections is play different audio-video frequency contents, and one section audio-video document can intercut several times in the middle of playing process, and the time has influenced viewer interest than long advertisement.And, using for example such audio-video frequency content of TV series of television-viewing, TV station plays 1 to 2 limited collection programme content in can only be at a fixed time, allows watching that the user can not follow one's inclinations at any time.And when spectators were interested to a lot of relevant informations of this programme content, TV can not be aside with for example program historical background, camera titbits, performers and clerks' information pass to spectators in the playing audio/video programs content.This passive viewing method, the numerous users' of incompatibility demand already.
Utilize network and computer to mutually combine and watch audio/video information to substitute traditional tv gradually, praised highly by a lot of netizens.Take this method to play corresponding video content, make the user select to watch video content, changed the deficiency of user's passive viewing audio frequency, video content according to self wish according to user's needs.Along with the development of Internet technology, the user can be on internet page program request watch video file in the network.The common player that is applicable to the Internet Online Video program request comprises at present: use the Flash player, Wmp (Windows Media Player, the windows media player) player that dodge the Flash technology, true player Real Player etc.
Wherein, the Flash technology is a kind of technology that can create rich interactive formula content, it can create interactive site, the rich-media advertisement, the directiveness medium, spectacular demonstration and recreation etc., and the Flash player of using the Flash technology has the good interface customizability, the user can arbitrarily formulate the interface appearance of Flash player (can formulate the interface color of Flash player such as the user, order button etc.), but the Flash player can only be play the Flv (FlashVideo that himself is supported, the blinking frequency) video content of form, and can't play other as WMV (Windows Media Video, windows media video), RM (Real Media, true medium), RMVB (RealMedia Variable Bitrate, true medium variable bit rate) video content of form such as, except that the Flash player, other player by the formulated interface that assignable graphical interactive software is developed has similar problem.
The player of format media contents such as the Wmp player is can displaying video, audio frequency, it can play the video content of forms such as WMV, RM, RMVB, but lack the good interface customizability, such as: when the page style of webpage is a black, when needing player also for the black interface, the Wmp player but can not provide the skin of black; When only placing broadcast and stopping two buttons on wishing player interface, the Wmp player but can't be cancelled other button and feedback areas.Like this, it is very dumb that the Wmp player just seems, the user can only be machine-made the User Interface that provides of use Wmp player self, and can not formulate the Wmp player interface as required flexibly.Except that the Wmp player, other for example function such as Reai Player player can support at least two kinds of format video files to play but the multi-format player that lacks the good interface customizability has similar problem.
This shows that existing player can't be taken into account good program decidability and support multiple format video file to play two kinds of performances.
