Media Content Updating via Changed Object Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multimedia communication, especially in videoconferencing, the existing methods waste bandwidth by transmitting all media content instead of only the changed media object attributes, leading to inefficient use of bandwidth resources.
Innovation Solution
A method where only the changed media object attributes are sent, along with an updating operation instruction, from the media transmit end to the media receive end, allowing the receive end to update the media content accordingly, thereby reducing bandwidth occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all media content is transmitted from the media transmit end to the media receive end, then the media receive end can update its stored media content, but a large amount of bandwidth is wasted
Solution Approach 1:
The patent extracts and transmits only the changed media object attributes from the complete media content, rather than transmitting all media content. This selective extraction of changed attributes significantly reduces bandwidth usage while still enabling the media receive end to update its stored content accurately
Solution Approach 2:
The patent segments media content into individual media objects and further segments changes into specific media object attributes. By identifying and transmitting only the changed attributes (such as position, size, or content of specific objects), the system achieves efficient bandwidth utilization while maintaining updating completeness
2Manufacturing precision
If all media content is transmitted to ensure complete updating, then updating accuracy is maintained, but transmission time increases
Solution Approach 1:
The patent extracts only the changed media object attributes for transmission, which maintains updating accuracy by providing precise change information while significantly reducing transmission time compared to sending complete media content
Solution Approach 2:
The patent applies partial action by transmitting only the necessary changed attributes rather than complete media content. This partial transmission is sufficient to achieve accurate updating while minimizing transmission time

AI summary
A media content updating method is presented, wherein the method is performed by a media transmit end, including obtaining a changed media object attribute on a side of the media transmit end; determining an updating operation instruction for the changed media object attribute according to a change type of the changed media object attribute; and sending a first announcement message to a media receive end, where the first announcement message includes the updating operation instruction and the changed media object attribute, so that the media receive end updates, according to the updating operation instruction and the changed media object attribute, media content that is on the side of the media transmit end and that is stored on a side of the media receive end. In embodiments of the present disclosure, an announcement message carries a changed media object attribute, so that a bandwidth occupancy rate can be reduced.
