Dual-Tuner Data Processing Apparatus for Simultaneous TV Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing television systems using the Miracast™ standard cannot simultaneously play multiple television channels, limiting users to watching only the channel being played on the main television system when using handheld mobile devices.
Innovation Solution
Incorporating two tuners, a processor, a receiving element, and a transmitting element in a data processing apparatus that allows for the generation and transmission of video/audio data from different television channels, enabling simultaneous playback of multiple channels on both internal and external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single tuner is used in the television system, then the device complexity is reduced, but the capability to simultaneously play multiple television channels is limited
Solution Approach 1:
The television system is segmented into multiple independent tuner units (first tuner and second tuner), each capable of receiving and processing different television channels independently. This allows the system to simultaneously process multiple channels without interference, resolving the contradiction between versatility and complexity by dividing the functionality into separate modular components.
Solution Approach 2:
The television system is designed with multi-functionality to serve multiple purposes: it can simultaneously provide television signals to both the internal playback device and external electronic devices through different tuners. This universal design enables the system to handle various viewing scenarios (single channel, multiple channels, simultaneous playback) without requiring separate dedicated hardware for each function.
2Adaptability or versatility
If the television system transmits video/audio data to external electronic devices, then the sharing capability is enhanced, but the internal playback device cannot access different channels simultaneously
Solution Approach 1:
The signal transmission path is segmented into separate channels: one path from the first tuner to the internal playback device, and another path from the second tuner to external electronic devices. This segmentation allows independent access to different television channels simultaneously, enabling both internal and external devices to receive different content without conflict.
Solution Approach 2:
The processor acts as an intermediary that manages and coordinates the operations of multiple tuners, playback devices, and transmission elements. It receives data requests from external devices, controls the appropriate tuner to generate the requested video/audio data, and manages the simultaneous transmission to multiple destinations, thereby facilitating easy access to different channels while maintaining sharing capability.
Data Source
AI summary
A data processing apparatus supporting simultaneous playback includes a processor, two tuners, a receiving element and a transmitting element. The first tuner generates first television data transmitted via a first frequency range, and provides the first television data to an internal playback device. The second tuner generates second television data transmitted via a second frequency range. The receiving element receives a data request for a selected television channel from an external electronic device. In response to the data request, the processor controls the second tuner to generate the second television data including video/audio data of the selected television channel. When the internal playback device performs playback according to the first television data, the transmitting element transmits the video/audio data of the selected television channel to the external electronic device for playback.
