Mobile Terminal Broadcast Storage Segmentation for Seamless Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital broadcast receivers with HDD-based storage systems face delays and image quality reduction due to the need to simultaneously store and reproduce broadcast content, as they can only process one file at a time, leading to jitter and inadequate seamless reproduction of broadcast content.
Innovation Solution
A method that involves delaying the reproduction of broadcast content in response to specific events, such as user interactions or phone calls, allowing for the storage of new content while previously stored content is reproduced, and then deleting the older content to enable continuous playback without file opening/closing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single file is used for storing and reproducing broadcast content in real-time, then the system structure is simple, but delays and image quality reduction occur due to file opening/closing operations
Solution Approach 1:
The patent divides the storage medium into multiple segments (first segment and second segment) that can be independently accessed. This segmentation allows the system to store and reproduce broadcast content in separate segments simultaneously, eliminating the need to open and close a single file during real-time operations, thereby reducing delays while maintaining manageable system structure.
2Loss of time
If storage space is divided into multiple segments for simultaneous storage and reproduction, then delays are minimized and image quality is maintained, but the device complexity increases
Solution Approach 1:
The storage medium is divided into multiple segments with distinct functions: one segment for storing incoming broadcast content and another for reproducing previously stored content. This segmentation enables simultaneous storage and reproduction operations without file opening/closing delays, while the segmentation management remains relatively simple through dedicated segment assignment.
Solution Approach 2:
The system preliminarily divides the storage medium into multiple segments before operation, designating specific segments for storage and reproduction functions. This preliminary action prepares the system to handle simultaneous storage and reproduction operations efficiently, avoiding delays during real-time broadcast processing while maintaining organized storage management.
3Ease of operation
If a single pointer is used for write/read operations, then the system is simple to manage, but seamless reproduction of broadcast content is inadequate
Solution Approach 1:
The patent employs multiple pointers (first pointer and second pointer) corresponding to different segments, allowing independent write and read operations to occur simultaneously without interfering with each other. This multi-pointer approach ensures seamless reproduction of broadcast content while keeping pointer management relatively straightforward through dedicated pointer-segment assignment.

AI summary
A mobile communication terminal is provided comprising a receiver for receiving broadcast content over a first broadcast channel; and a controller for controlling reproduction of the broadcast content on a display of the mobile terminal. In response to detecting a first event, the controller receives a first request to delay reproduction of broadcast content in real-time. In response to receiving the first request the controller stores, in a storage medium, first broadcast content received between a time T1 and T2. In response to detecting a second event, the controller reproduces the first broadcast content. The controller stores second broadcast content received after a time T3. After the first broadcast content is reproduced, the controller reproduces the second broadcast content.
