Segmented Streaming Content Management with Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional streaming content management techniques lack effective playback positioning functions, only allowing pausing of currently broadcast content or replaying past content within a limited time period without precise control.
Innovation Solution
A streaming content management apparatus and method that records incoming content streams in segments with added indexing information, enabling precise playback positioning by segmenting content into predetermined time durations or chapters, and using metadata for efficient retrieval and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional time shift techniques are used to record and replay streaming content, then basic pausing and limited replay functionality is provided, but effective playback positioning function is lacking
Solution Approach 1:
The patent segments the recorded streaming content into discrete units called segments, each with assigned indexes. This segmentation allows the system to jump directly to specific segment positions during playback, enabling precise playback positioning instead of sequential replay through the entire recorded content.
Solution Approach 2:
The patent performs preliminary indexing of content segments during the recording phase. By pre-assigning indexes to segments as they are recorded, the system prepares the playback structure in advance, allowing users to quickly locate and jump to specific content points without having to replay through intermediate segments.
2Productivity
If streaming content is recorded without indexing, then storage space is conserved, but playback positioning and retrieval efficiency deteriorates
Solution Approach 1:
The patent divides content into segments and assigns indexes to each segment, creating a structured navigation system. This segmentation approach enables efficient content retrieval by allowing direct access to specific segments through their indexes, dramatically improving productivity in locating and replaying specific content portions.
Solution Approach 2:
The patent introduces an intermediary indexing layer between the raw content stream and the playback function. This index structure acts as a mediator that translates user playback position requests into specific segment identifiers, enabling efficient content retrieval without requiring complex random access to the entire recorded stream.
3Measurement precision
If content is segmented into small units with indexes, then playback positioning precision is improved, but recording and processing complexity increases
Solution Approach 1:
The patent implements segmentation of recorded content into manageable units with assigned indexes, achieving precise playback positioning. The segmentation allows the system to accurately locate and replay specific portions of content by referencing segment indexes, thereby improving measurement precision for playback positioning despite the added processing complexity.
Data Source
AI summary
A streaming content management apparatus and method for recording and replaying video and audio data using a real time video indexing function are provided. A streaming content management apparatus of a multimedia broadcast receiver includes a recording unit for recording an incoming content stream in units of segment together with indexes and a player for replaying the content stream recorded by the recording unit in response to an index that is input to request playback from a segment corresponding to the input index. The streaming content management apparatus divides the streaming content incoming through a broadcast channel in units of segment and stores segments of the streaming content with storage index and chapter information such that it is possible to quickly retrieve a playback position using the storage index or chapter information.
