Abstract
The invention discloses a method for synchronizing videos/score according to time stamps on a mobile terminal. The method comprises the following steps: installing a plurality of digital high-definition cameras on a sports ground according to different angles and regions, and broadcasting the same competition through the plurality of digital high-definition cameras in a live way at the same time; automatically adding a current time stamp during acquisition of videos from the plurality of high-definition camera videos; performing real-time character live broadcast through a scoring tool on the sports ground; and automatically adding the current time stamp during acquisition of character information. According to the method for synchronizing the videos/score according to the time stamps on the mobile terminal provided by the invention, a playing speed is adjusted according to the time stamps, so that video data and character data are played synchronously, and the playing smoothness and picture consistency are enhanced.
Description
Technical field
The present invention relates to a kind of sports event live broadcast method, be specifically related to a kind of in the method for mobile terminal according to timestamp synchronization video/score.
Background technology
Along with the development of on-the-spot broadcasting network technology, user can watch sports tournament online by network, such as, carry out viewing Basketball Match, needs the video of collection site, lteral data, namely video data, lteral data are transferred to other users, and locate other users the data playing this collection.
Traditional live telecast is, in live broadcast vehicle, video data, lteral data are transferred to terminal behind interflow.But live telecast somewhat expensive.Use network direct broadcasting cost lower, but Problems existing is, the time irreversibility that video data, lteral data transmit due to Internet Transmission reason, just there is word and the inconsistent problem of picture in this, under normal circumstances, Word message can faster than video information transmission, causes video pictures also not play, word game situation shows in advance, causes poor user experience.
For above-mentioned problem, the invention provides a kind of in the method for mobile terminal according to timestamp synchronization video/score, by automatically adding current time stamp in the video gathered, word, after terminal gets video information and word, first take out the timestamp of video, according to the time that video current time stamp adjustment word is play, by advanced Word message buffer memory, thus realize word and picture synchronization.
Summary of the invention
Provided by the invention a kind of in the method for mobile terminal according to timestamp synchronization video/score, specific as follows:
Sports ground installs several digital high-definition camera according to different angles and region, by several digital high-definition camera live same bout simultaneously; When gathering several digital high-definition camera video, automatically add current time stamp;
Sports ground carries out real-time text by score instrument live; When gathering Word message, automatically add current time stamp;
After terminal gets video information and word, first take out the timestamp of video, according to the time that video current time stamp adjustment word is play, by advanced Word message buffer memory, thus realize word and picture synchronization.
Above-mentioned is a kind of in the method for mobile terminal according to timestamp synchronization video/score, wherein:
The decoding of terminal receiving video data obtains corresponding timestamp, receives written broadcasting live information, takes out the timestamp in live information;
According to the written broadcasting live information that the timestamp buffer memory of current video upgrades than video time;
According to the current video time, controlling written broadcasting live information time must be strict consistent with video time, can not exceed video time, synchronous to make video data, Word message play.
Above-mentioned is a kind of in the method for mobile terminal according to timestamp synchronization video/score, wherein:
The timestamp of video data, Word message and correspondence thereof is carried out coding and is sent to high in the clouds.
The present invention has following beneficial effect relative to prior art:
Provided by the invention a kind of in the method for mobile terminal according to timestamp synchronization video/score, by the timestamp according to current video data, Word message, according to the current video time, controlling written broadcasting live information time must be strict consistent with video time, calculate the time difference that current video is play, and obtain regulations speed according to the time difference of current broadcasting, playback rate is regulated according to regulations speed, make video data, Word message data playback synchronous, improve video data, the fluency of Word message broadcasting and the consistency of picture.
Accompanying drawing explanation
Fig. 1 is provided by the invention a kind of at the schematic diagram of mobile terminal according to the method for timestamp synchronization video/score.
Embodiment
Below in conjunction with accompanying drawing and example, the invention will be further described.
The method of a kind of many group cameras provided by the invention live broadcasting.
Sports ground installs several digital high-definition camera according to different angles and region, by several digital high-definition camera live same bout simultaneously; When gathering several digital high-definition camera video, automatically add current time stamp;
Sports ground carries out real-time text by score instrument live; When gathering Word message, automatically add current time stamp;
After terminal gets video information and word, first take out the timestamp of video, according to the time that video current time stamp adjustment word is play, by advanced Word message buffer memory, thus realize word and picture synchronization.
Terminal use uses mobile terminal display video information, Word message reproduction time keeps synchronous real-time game situation information.
The decoding of terminal receiving video data obtains corresponding timestamp, receives written broadcasting live information, takes out the timestamp in live information;
According to the written broadcasting live information that the timestamp buffer memory of current video upgrades than video time;
According to the current video time, controlling written broadcasting live information time must be strict consistent with video time, can not exceed video time, synchronous to make video data, Word message play.
As shown in Figure 1, the written broadcasting live time is 10:00, and to be 9:55, APP play the time of net cast, and time of Word message is adjusted to 9:55, namely cushions Word message time 5min, plays end like this at APP, make video, Word message is consistent.
Although the present invention discloses as above with preferred embodiments; so itself and be not used to limit the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when doing a little amendment and perfect, therefore protection scope of the present invention is when being as the criterion of defining with claims.
