Video Transmission Apparatus for Quick Response Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiencies in quickly finding desired playback positions in video content, leading to decreased quick response performance when seeking through video playback or editing, as existing methods require transferring and playing back initial segments of video content to reduce waiting times.
Innovation Solution
A transmission apparatus, relay apparatus, and reception apparatus system that transmits first encoded data for playback at a first quality and selectively transmits portions of second encoded data corresponding to user-defined playback positions, allowing playback at a higher quality while minimizing data transfer and improving response time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the first several tens of seconds of video content are automatically transferred to reduce waiting time, then the waiting time until start of streaming playback is reduced, but when the desired playback position is not within this initial segment, the user experiences increased waiting time due to arbitrary seeking positions
Solution Approach 1:
The system performs preliminary actions by automatically transferring and storing the first several tens of seconds of video content (initial segment) to the user terminal before the user actually needs it. This preliminary transfer reduces the waiting time when users want to watch from the beginning or early parts of the video, while the system prepares additional segments on-demand based on user seeking behavior.
Solution Approach 2:
The system dynamically adjusts the video segment transfer strategy based on user behavior. When users perform seeking operations to positions beyond the initial segment, the system responds by transferring additional video segments corresponding to those sought positions, thereby maintaining quick response performance regardless of where users want to watch.
2Productivity
If video content is transferred in full to ensure immediate playback at any position, then quick response performance is improved, but data transfer amount and storage requirements increase significantly
Solution Approach 1:
The video content is divided into multiple segments based on time positions. The system transfers only specific segments (initial segment of several tens of seconds, and additional segments corresponding to user-sought positions) rather than the entire video content. This segmentation approach reduces data transfer amount while maintaining the ability to provide quick playback at user-desired positions.
Solution Approach 2:
The system extracts and transfers only the necessary video segments that users are likely to watch - specifically the initial segment and additional segments corresponding to sought positions - rather than transferring the complete video content. This extraction strategy minimizes data transfer while ensuring quick response performance for actual user viewing needs.

AI summary
[Object] To propose a novel and improved transmission apparatus, relay apparatus, and reception apparatus that have improved quick response performance involved in content processing. [Solution] According to the present disclosure, there is provided a transmission apparatus including: a storage unit configured to store first encoded data used for playback at first quality and second encoded data used for playback at second quality higher than the first quality, for same temporally continuous content; and a communication unit configured to transmit the first encoded data to a reception apparatus, and thereafter, receive first position information relating to a data position from the reception apparatus, and transmit a portion of the second encoded data corresponding to the first position information to the reception apparatus.
