The invention relates to a method and a device for playing a news video, which mainly utilize news resources to be displayed in a scene of a set top box, or displayed in video playing programs of other mobile terminals of a user, such as a tablet, a mobile phone and the like, or used for pushing the news resources to a user terminal from a server through a news template, and have the basic ideas that: after key frames in video information are extracted and converted into picture information when the video information is included in news, the converted picture information and character information displayed in the news are displayed together, so that the news is more smooth when displayed, and the experience of a user in browsing or reading the news is improved.
The present embodiment may be applicable to a news plug-in for playing a news video, where the method may be executed by the news plug-in, where the news plug-in may be implemented by software and/or hardware, and may be generally integrated in a system installed in a set top box or other user terminals, or controlled by a central control module of the set top box or other user terminals, as shown in fig. 1, which is a flowchart of a method for playing a news video according to the present invention, and the method specifically includes the following steps:
in step 110, receiving a news resource;
the news resource may consist of a plurality of news items, which are typically pushed by the server into corresponding news plugins.
In step 120, detecting whether the news resource contains video information;
the news content of each news item can include pure character information, picture information, video information and the like, and when the news content includes any one of the video information or the picture information, the news item is indicated to be non-pure character information.
The attribute parameter tag of the video information may be denoted by "V", and in a possible embodiment, the detection may be performed by whether the attribute parameter tag includes news content for which "V" is available.
In step 130, when the news resource contains video information, extracting a key frame from the video information and playing the video information;
in a possible implementation manner, when the news resource includes a piece of news, it is determined whether the attribute parameter of the news includes news content with a parameter labeled "V", and when it is determined that the news content with a parameter labeled "V" is included, it is determined that the news resource includes video information.
Extracting key frames from the video information, wherein the key frames can be frames marked as important in frame marks of the video information, or frames at the middle positions in the video information can be selected as key frames, and the video information is not completely loaded, but the key frames are selected and then loaded and played.
In step 140, when the news resource does not contain video information, the news resource is filled into a news template for display.
The news resource does not contain video information, namely the news resource is pure character information, and the news resource can be directly filled into a template and displayed to a user.
According to the method, after the key frames in the video information are extracted and converted into the picture information when the fact that the news to be played or displayed comprises the video information is detected, the picture information and the text information displayed in the news are displayed together, so that the news is displayed more smoothly, the problem that a user abandons reading of the corresponding news due to low network speed or insufficient flow and the like is solved, and the effect that the news plug-in can play the corresponding news with the video information more quickly and more smoothly when the news plug-in displays the corresponding news is achieved.
In another implementation scenario of the exemplary embodiment of the present invention, after the extracting the key frame from the video information and playing the video information, the method further includes:
converting the key frame into a picture;
and playing the picture while playing the news resource.
The key frame is a component of the video information, the format of the key frame is generally determined by the video information, and the key frame is converted into a picture information format, so that the picture can be completely played when other contents in news resources are played, and the situation that the picture cannot be played due to incorrect format is avoided.
In another implementation scenario of an exemplary embodiment of the present invention, the method further includes a process of matching the playing speed of the key frames or pictures to other information in the news resource, which includes the following steps:
acquiring the playing speed of the character information in the news resource;
and adjusting the speed of playing the key frames or the pictures according to the playing speed.
By the method, the speed of playing the key frames or pictures of the video information is matched with the speed of playing the text information in the news resource, and particularly, when the video information is displayed on the news resource in a rolling mode, a user can know the resource information more quickly by adopting the method.
In another implementation scenario of the exemplary embodiment of the present invention, when the news resource contains video information, the extracting a key frame from the video information and playing the video information, as shown in fig. 2, may include:
in step 210, acquiring the playing speed of the text information in the news resource;
in step 220, deriving an extraction frequency for extracting key frames from the video information according to the playing speed;
the extracted key frame can be extracted according to the playing speed of the text information, and when the text information is closed, excessive frame extraction of the video information can be prevented.
In step 230, extracting key frames from the video information according to the extraction frequency;
in step 240, converting the extracted key frame into picture information;
in step 250, the picture information is played in the order of extracting key frames in combination with the playing speed.
By the method, the key frame is determined to be extracted or converted into the picture through the playing speed of the text information (generally, the rolling speed of the text information during rolling display), so that the speed of playing the key frame or the picture of the video information is further matched with the speed of playing the text information in the news resource, and particularly, when the text information is displayed on the news resource in a rolling mode, a user can know the resource information more quickly by adopting the method.
In another implementation scenario of the exemplary embodiment of the present invention, as shown in fig. 3, the method further includes:
in step 310, detecting whether the playing speed of the picture information is matched with the playing speed of the text information;
in step 320, when the playing speeds of the two are not matched, adjusting the playing speed of the picture information;
in step 330, when the playing speeds of the two are matched, the playing speed of the picture information is corrected according to the playing speed of the text information.
By the method, the speed matching between the picture playing and the text displaying can be further ensured, so that a user can obtain excellent news reading experience when watching news.
