Playback Device Content Selection via Identification Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content playback systems face significant processing loads when transitioning between playback periods due to the need to parse and reselect representations, representation groups, and subsets, leading to inefficiencies in content selection and playback.
Innovation Solution
A playback device and method that include selection, acquisition, and playback means to efficiently select and play content based on identification information within content information for each playback period, reducing the need for full reanalysis by referencing identification information for seamless transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the playback device parses and reselects all representations, representation groups, and subsets in each playback period, then content selection accuracy is maintained, but processing load increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-organizing content into periods with identification information that indicates continuity relationships. The playback device uses this pre-established structure to directly identify and select content for the next playback period without performing full reanalysis, thereby maintaining selection accuracy while reducing processing load.
2Reliability
If the playback device performs full reanalysis of content information in each playback period, then content selection reliability is ensured, but playback efficiency decreases
Solution Approach 1:
The content information is pre-organized with identification information that establishes reliability guarantees before playback. The playback device leverages this pre-established structure to efficiently transition between periods without compromising selection reliability, thus improving playback efficiency while maintaining content selection accuracy.
3Loss of time
If the playback device references identification information for content selection, then processing time is reduced, but information completeness may be compromised
Solution Approach 1:
The patent segments content information into periods with identification information that captures essential continuity relationships. This segmentation allows the playback device to process only relevant identification information rather than complete content details, reducing processing time while preserving necessary information for accurate content selection and seamless transitions.

AI summary
A client (1) is provisioned with a content selection unit (13) for referencing description information (26), selecting content to be played in a certain period, and at the same time, and selecting content to be played at the next period from an id of a subset that is the same as the subset selected at the period, a request execution unit (14) for requesting the transmission of the selected content, and a content playback unit (15) for continuously playing the content transmitted in response to the request.
