Abstract

The invention is used in IPTV network comprising IPTV service system, set-top box and display device. The system comprises: a subtitle control module located in IPTV service system, which is used for defining the subtitle information in a HTML webpage, and sending the HTML webpage to said set-top box; a subtitle resolving module located in said set-top box, which is used for translating the HTML webpage to a displayable webpage; a subtitle stacking module located in the set-top box, which is used for stacking at least a part of the displayable webpage into the display interface on the screen.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a system and method for realizing scrolling letters on an IPTV set-top box. Background technique [0002] IPTV (Internet TV) is a data value-added service that uses "TV + set-top box" as the main terminal equipment to provide users with interactive TV and multimedia services through the IP data network. In IPTV service applications, it is a common service to superimpose prompt subtitles on the video during the video playback of the set-top box. There are many ways to realize this service. The usual method is to send the subtitles to be displayed to the set-top box through some means, and the set-top box is responsible for the specific superimposition process of the subtitles. This implementation method has great limitations, mainly due to the lack of flexibility in implementation, such as the position of subtitle superimposition, the direction of subtitle scrolling...
