DVR Ticker Playback System Replacing Stale Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital video recorders (DVRs) currently record news tickers as part of video streams, resulting in stale information during playback, which is not useful to viewers as it reflects past events and lacks real-time updates.
Innovation Solution
A system and method within DVRs that analyzes the current broadcast signal for ticker information during playback, replacing pre-recorded ticker data with real-time data, ensuring viewers receive current news updates while watching recorded programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the DVR records the television program including ticker event data as part of the recording, then the complete program content is preserved, but the ticker information becomes stale during playback and loses usefulness
Solution Approach 1:
The system performs preliminary actions by storing the channel identifier and ticker data structure during recording, and prepares the ticker replacement mechanism in advance during playback by tuning to the original channel and capturing current ticker data. This preliminary preparation enables the seamless replacement of stale ticker information with current information without requiring complete re-recording.
Solution Approach 2:
The patent introduces an intermediary ticker replacement system that acts as a mediator between the recorded video content and the current broadcast ticker data. This intermediary layer captures current ticker information from the live broadcast and overlays it on the recorded playback, effectively decoupling the static recorded content from the dynamic need for current information.
2Ease of operation
If the DVR plays back the recorded video stream with the original ticker data, then the playback is simple and straightforward, but the ticker information is already known and not useful to the viewer
Solution Approach 1:
The playback system is designed with multi-functionality, capable of operating in both simple playback mode (using original recorded ticker data) and enhanced playback mode (with current ticker information overlay). This universal design allows the system to adapt to different user needs while maintaining ease of operation through automatic mode selection or user preference settings.
Solution Approach 2:
The ticker display system transitions from a static state (original recorded ticker) to a dynamic state (current live ticker) during playback. The system dynamically adjusts the ticker information source based on whether current broadcast data is available and relevant, enabling the playback function to evolve from simple reproduction to intelligent information delivery.
3Loss of information
If the DVR captures and analyzes the current broadcast signal during playback to replace ticker information, then current ticker information is displayed, but the system complexity increases
Solution Approach 1:
The patent segments the ticker information processing from the main video playback stream. By separating the ticker data extraction, analysis, and replacement functions into distinct modular components, the system reduces overall complexity while achieving current information display. The segmentation allows independent optimization of each function and simplifies the integration with the existing playback infrastructure.
Data Source
AI summary
A system and method of controlling the playback of the event stream information of a particular television channel by a digital video recorder (DVR). The DVR is a computer system configured with a hard drive and video decoder/encoder devices. The hardware environment of DVR (100) includes an input interface (102), tuner (105), MPEG-2 encoder (120), MPEG-2 decoder (110), external mass storage device (125), a central processing unit (CPU) (135), internal memory (127), operating system (140), and event stream generator (250). The system and method of controlling the playback function of the present invention is primarily implemented within event stream generator (250). Event stream generator (250) generates a new video stream for playback onto the television by incorporating the broadcasted event stream information into the selected recorded video stream.
