Problems solved by technology

However, in fact, not every user understands the above knowledge. If they do not understand, they are likely to make wrong choices.
[0008] For example, according to the current actual bandwidth, the user could have downloaded information with better quality to play with the CD, but because he selected a bandwidth smaller than the current actual bandwidth, he downloaded information with poor quality to play with the CD. The user brings poor playback effect, which affects the user's interest in watching CD information
On the other hand, if the current actual bandwidth is used, the user can only download information with poor quality to match the disc playback, but because the selected bandwidth is greater than the current actual bandwidth, the user downloads information with better quality that does not match the current bandwidth. It is very easy to cause the download content to be delayed than the information read directly from the disc, so it is difficult to achieve synchronous playback

[0027] On the one hand, the network communication device 22 is used to receive the disc ID and the URL of the required download content sent by the reading device 21 , and on the other hand, to receive the current network link bandwidth transmitted by the bandwidth detection device 26 . The network communication device 22 includes a sending device 27 and a receiving device 28 . The sending device 27 is used to send a download request, and the receiving device 28 is used to receive information corresponding to the download request. The content of the sent download request includes the URL of the desired downloaded content, the disc ID and the current bandwidth information of the network link. According to the first embodiment of the present invention, when the bandwidth changes, the network communication device 22 sends the changed bandwidth information together with the download request to the network server 60 .

[0028] The above-mentioned download request is sent to the ne...

example 1

[0036] In Example 1, the quality selection menu of the desired download content is pre-stored on the optical disc. In this way, the information read out by the reading device 21 includes the content stored on the optical disc to be played, the ID of the optical disc, the URL corresponding to the required downloading content, and the quality selection menu of the required downloading content. The quality selection menu is as described in the first embodiment.

[0037] The bandwidth detection means 26 is used to detect the current bandwidth in real time (as described in the first embodiment), and output the bandwidth to the selection means 31 . Among them, the corresponding API (Application Programming Interface) is stored in the selection device 31 .

[0038] The network communication device 22 includes a sending device 27 and a receiving device 28 . Wherein, the quality selection menu of the desired downloaded content from the reading device 21 can be output to the selection...

example 2

[0042] In Example 2, the quality selection menu for the desired download is stored on the web server instead of on the disc. In this case, the bandwidth detection means 26 outputs the detected bandwidth information to the selection means 31 . The sending device 27 in the network communication device 22 sends a request for downloading the quality menu to the network server, and the request includes the disc ID and the URL corresponding to the desired download content.

[0043] After receiving the download request, the network server sends quality selection menus of all content to be downloaded to the network communication device 22 . The network communication device 22 outputs the received quality selection menu to the selection device 31 . According to the current bandwidth detected by the bandwidth detection device 26 , the selection device 31 selects a quality that meets the bandwidth from the quality menu of the currently required downloaded content, and outputs the qualit...

Abstract

A play content device and method by accessing prestored content which containing information related with downloaded content, checking available bandwidth according to downloaded content, then sending a request containing bandwidth information, receiving relative downloaded content accorded with checked bandwidth, playing downloaded content combined with prestored content. Said invention adopts real time automatically checking current available bandwidth of connected network to dynamically changing downloaded content quality, realizing seamless playing without the problem resulted from user self-selecting quality.

Description

Background technique [0001] The present invention relates to a method and device for playing content, in particular to a method and device for downloading and playing content of appropriate quality by detecting in real time the available bandwidth of a playback device linked to a network. [0002] With the rapid development of optical discs and optical disc playing technologies, more and more contents are stored on the network server, so that these contents can be downloaded to the player during the playing of the optical disc, so as to cooperate with the player to play the optical disc. [0003] The downloaded content can be applications, audio and subtitles, etc. The application program refers to an application program expressed in JAVA language or an application program expressed in other programming languages. The application programs expressed by the JAVA language are: advertisements, games, animations, and execution programs for controlling the process of playing CDs wr...
