Media Hub Simultaneous Multi-Tuner Video Audio Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Set-top boxes with multiple tuners cannot simultaneously provide multimedia content from multiple TV channels to a display device and speakers, limiting users to watching only one channel at a time despite having multiple tuners.
Innovation Solution
A media hub device that allows users to view image data and hear audio data from multiple tuners simultaneously by tuning multiple channels and providing scaled image data and assigned audio channels for simultaneous display and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a set-top box includes multiple tuners, then the capability to receive multiple TV channels is improved, but the ability to simultaneously provide multimedia content from multiple channels to display devices is limited
Solution Approach 1:
The patent divides the multimedia content distribution into separate video and audio streams from different tuners. Each tuner's content is processed independently through scaling and audio channel assignment, allowing multiple channels to be simultaneously displayed without interference. This segmentation enables the set-top box to overcome the limitation of only providing content from one channel at a time.
2Productivity
If multiple tuners are used to record multiple TV programs, then the productivity of content recording is improved, but the simultaneous playback capability to multiple display devices is restricted
Solution Approach 1:
The patent introduces spatial dimensionality by assigning different audio channels (left, center, right, surround) to different tuner sources. This dimensional separation allows the system to simultaneously output multiple TV programs to the same display device or multiple display devices, transforming the limitation of single-channel playback into a multi-dimensional audio-visual experience.
3Reliability
If a set-top box provides content from one channel at a time, then the audio output quality is maintained, but the user experience of watching multiple programs simultaneously is limited
Solution Approach 1:
The patent applies different processing qualities to different audio streams based on their source and assignment. Each tuner's audio output is independently assigned to specific audio channels with appropriate scaling and positioning, allowing high-quality audio reproduction for each program while enabling simultaneous playback. This local quality approach maintains audio fidelity for each channel while providing enhanced user experience through multi-program viewing.
Data Source
AI summary
A device is configured to tune multiple tuners to multiple television channels. The device may receive image data and audio data for the television channels from the tuners. The device may provide the image data from the tuners for display on a display device and for display at a same time. The device may assign the audio data from a group of the tuners to respective audio channels. The device may provide the audio data from the group of tuners for output at the same time via the respective audio channels.
