Problems solved by technology

[0003] In order to bring a better picture quality experience, 4K and 8K video resources adopt high-bit-rate encoding methods. Due to the limited external file reading and writing performance of the smart TV system itself, file data reading performance occurs when high-bit-rate sources are played. It cannot keep up with the data consumption speed of decoding and playback, which in turn leads to the phenomenon of freeze on the playback screen, which greatly affects the overall video viewing experience and also affects the overall performance of the product.

Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with specific examples, but the present invention is not limited by the content of the examples in any form.

[0019] The invention proposes a method for playing high-bit-rate video resources, which mainly includes bit-rate pre-analysis technology and high-speed file reading technology. Among them, the bit rate pre-analysis technology is used to extract and analyze the bit rate of the video resource in advance, so as to obtain the real bit rate value of the video resource; the high-speed file reading technology is used to read the data of the video resource file at a high speed, and its The basic technology comes from memory mapping technology.

[0020] In this embodiment, the smart TV plays 8K high-bit-rate video resources on a local mobile hard disk as an example. The smart TV is connected to the mobile hard disk through a USB interface, and multiple 8K high-bit-rate video ...

Abstract

The present invention provides a method for playing high-bit-rate video resources, comprising the following steps: Step 1, pre-analyzing and extracting the bit-rate information of the video resource to be played, and extracting the bit-rate information of the video resource as a video resource record and save the key attribute information; step 2, read the bit rate information extracted in step 1 of the video resource to be played, and compare this bit rate information with the high bit rate threshold value preset by the system, and according to the comparison result Enter high-speed reading playback mode or normal reading playback mode. Step 3: After the current video resource is played, close the current read and play mode, continue to play the next video resource, and re-enter step 2 until all video resources are played. The method of the present invention can realize smooth playback of high-bit-rate video resources, and improve the viewing effect of high-bit-rate video resources on smart TVs.

Description

technical field [0001] The invention belongs to the technical field of multimedia playing, and relates to a method for playing high bit-rate video resources, a terminal device and a storage medium. Background technique [0002] With the popularization of 4K smart TVs and the rise of 8K video resources, the decoding and playback capabilities of smart TV terminals are getting stronger and stronger. The video players of smart TVs can directly play local 4K and 8K video resources, bringing users Very good audio-visual experience. [0003] In order to bring a better picture quality experience, 4K and 8K video resources adopt high-bit-rate encoding methods. Due to the limited external file reading and writing performance of the smart TV system itself, file data reading performance occurs when high-bit-rate sources are played. It can't keep up with the data consumption speed of decoding and playback, which in turn causes the playback screen to freeze, which greatly affects the ove...
