Dual Tuner Playback Channel for Satellite and OTA Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite television systems lack access to local sub-channels, which are important for users seeking local news and weather information, due to customer interest, business, and regulatory challenges.
Innovation Solution
A dual tuner device configuration that communicates multiple streams to an external device, allowing for the reception of both satellite and over-the-air signals, enabling access to local content through a multiplexer system that manages and routes signals effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If satellite television systems use a single tuner for receiving satellite content, then the system is simple and cost-effective, but users cannot access local sub-channels that are not carried by the satellite provider
Solution Approach 1:
The patent implements a dual tuner system where the first tuner receives satellite broadcast content and the second tuner receives over-the-air local broadcast content. Both tuners share a common playback channel, allowing the system to universally handle multiple content sources through a single playback interface, thereby providing access to both satellite and local sub-channels without requiring separate playback paths.
Solution Approach 2:
The patent combines multiple data streams from different tuners (satellite and over-the-air) through a multiplexer that routes content to a shared playback channel. This merging approach consolidates the playback function into a single channel while maintaining the ability to receive and process multiple independent broadcast streams simultaneously.
2Loss of information
If satellite television systems provide only satellite content through a single tuner, then the system remains simple, but users lose access to local news and weather information available on local sub-channels
Solution Approach 1:
The dual tuner system enables the satellite receiver to universally access both national satellite content and local over-the-air content including news and weather sub-channels. The shared playback channel ensures that locally important information becomes available alongside satellite programming without requiring separate playback devices.
3Productivity
If the system uses separate playback channels for each tuner, then each content source can be processed independently, but the system complexity and resource requirements increase
Solution Approach 1:
The patent merges the playback function into a single shared channel that handles content from both tuners. The multiplexer manages the routing of different content streams to this common playback path, maintaining independent processing capabilities while consolidating the playback output to reduce system complexity and resource requirements.
Data Source
AI summary
A system and method for processing multiple streams over a single playback channel includes a receiving device and a tuner module having a first tuner and a second tuner. The first tuner has a first device node within the receiving device associated therewith. The second tuner has a second device node within the receiving device associated therewith. A multiplexer has a playback device module associated therewith. A tuner driver configures the playback device module for a first multiplexer channel and a second multiplexer channel. The tuner module communicates a first tuner signal and a second tuner signal to the receiving device. The playback device communicates first data signals from the first tuner through the first multiplexer channel to a first destination. The playback device communicates second data signals from the second tuner through the second multiplexer channel to a second destination.
