Problems solved by technology
At present, most users in our country use ADSL to access the broadband network, which cannot fully meet the needs of real-time transmission of TV video streams. Therefore, if sequential streaming is used, the program will be very slow and may pause after a period of smooth playback. Subsequent programs can only be played after a period of buffering
This kind of pause will occur periodically and frequently, which is completely unacceptable for TV users who are accustomed to enjoying smooth programs
If the real-time streaming transmission method is adopted, in order to ensure that the multimedia information can be played smoothly under the current network conditions, some data of the original multimedia information must be cut down, resulting in damage to the video and audio quality. This is also true for TV users. unacceptable

Description
technical field [0001] The invention relates to the technical field of multimedia information, in particular to a method for downloading and playing multimedia information with a TV set-top box as a terminal and a set-top box device for realizing the method. Background technique [0002] On the Internet, the transmission and playback of multimedia information using computers as terminals has become very popular. Especially in recent years, with the advancement of access technology and the development of multimedia information compression algorithms, satisfactory results can be achieved no matter whether it is downloaded or transmitted through streaming media. However, the method of using the television set as the playback terminal to transmit and play network multimedia information has not been widely accepted by users at present. An important reason for this problem is that the existing multimedia information playback technology cannot meet the needs of TV users. [0003]...
