Subtitle Language Switching in Multimedia Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multimedia systems face user experience deterioration when subtitle languages are changed due to differences in subtitle lengths, leading to incomplete viewing of subtitles during transitions between languages.
Innovation Solution
A method and device for transmitting and receiving multimedia signals that detect requests to change subtitle languages, allowing for the replay of previous subtitle data during the transition period to ensure complete user experience, by transmitting information required for replaying data before the given point in time among the first-type and second-type data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If subtitle language is changed during reproduction, then users can access subtitles in different languages, but users cannot fully read subtitles during the transition period due to length differences
Solution Approach 1:
The system performs preliminary actions by detecting the subtitle language change request in advance and transmitting reproduction information for previous subtitle data before the actual language switch occurs. This allows the reception device to prepare and display the previous subtitle content during the transition period, ensuring users can fully read subtitles without information loss.
Solution Approach 2:
The transmission device acts as an intermediary by generating and transmitting reproduction information for previous subtitle data between the subtitle language change request and the actual language switch. This intermediary mechanism ensures that subtitle content completeness is maintained during the transition by providing the necessary information for replaying previous subtitles.
2Adaptability or versatility
If subtitle language is changed during reproduction, then users can access subtitles in different languages, but user experience deteriorates due to incomplete subtitle viewing
Solution Approach 1:
The system performs preliminary actions by detecting the subtitle language change request in advance and transmitting reproduction information for previous subtitle data before the actual language switch occurs. This allows the reception device to prepare and display the previous subtitle content during the transition period, ensuring users can fully read subtitles without information loss.
Solution Approach 2:
The transmission device uses feedback by detecting the subtitle language change request from the reception device and responding by transmitting the necessary reproduction information for previous subtitle data. This feedback mechanism ensures that user experience is maintained during language transitions by automatically providing the appropriate subtitle replay information.
3Loss of information
If previous subtitle data is replayed during language transition, then users can fully read subtitles, but additional data transmission is required
Solution Approach 1:
The transmission device extracts only the necessary reproduction information for previous subtitle data that is required for the language transition, rather than transmitting all subtitle data. This extraction approach ensures that subtitle content completeness is maintained while minimizing the additional data transmission volume to only what is essential for replaying the previous subtitles during the transition period.

AI summary
A method of a transmission device in a multimedia system comprises the steps of: detecting a request for changing first-type data into second-type data while the first-type data is being played at a given point in time; and transmitting, before the second-type data is played, information necessary for replaying data, among the first-type data, played prior to the given point in time, and/or data, among the second-type data, played prior to the given point in time.
