[0021] In the actual use process, the number of advertisements is completely random. Therefore, as long as the highest playback resolution of the feature film is greater than 1080p, there is a 50% probability that the video playback device will have the above-mentioned black screen waiting process, that is, the fast switching failure will occur, which seriously affects It reduces the timeliness of video switching, and seriously reduces the user experience, which cannot meet the needs of the market

The invention relates to a streaming media technology, and discloses a method for switching streaming media videos and an intelligent television. The method aims to improve the switching timeliness ofstreaming video. The method comprises the following steps: according to the low playback resolution and the high playback resolution respectively downloading the starting part data and the continuingpart data of the main video from the server, As that Main decode is occupied by the multimedia presentation information, At first, that start-up data is play through the Sub decoder, After the multimedia display information is played, A main decode is switched to play that data of the follow-up part, In this way, seamless switching of the main video and multimedia presentation information can berealized, while saving as much memory as possible, The invention eliminates the defect that the dual-channel decoder cannot switch back to the main video with high playback resolution when inserting an even number of multimedia display information in the main video with maximum probability, effectively improves the timeliness of streaming media video switching, guarantees the streaming media videoplayback performance of the system, and improves the user experience.
Description
technical field [0001] The invention relates to streaming media technology, in particular to a streaming media video switching method and a smart TV. Background technique [0002] With the development of streaming media technology, video playback devices have higher and higher requirements for fast switching. Some applications in the European and American markets have clear performance requirements for video switching and advertising insertion. For example, some players even require the switching time of advertisement insertion to be within 250ms. [0003] In order to meet this requirement, the video playback device must have at least two decoders. While the first decoder is decoding and playing the feature film, the second decoder is used to decode and cache the data of the multimedia display information, where the multimedia display information is resolution Video sources with relatively low rate, such as advertisements, natural disaster warnings, real-time news inserts, ...
