Voice Driven Cross Service Search on Second Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IPTV systems face challenges in user input, particularly on small devices like smartphones and tablets, due to the difficulty of typing search terms on virtual keyboards, which are not conducive to typing and require true calibration.
Innovation Solution
Implementing a system where a second display device acts as a voice input device to perform cross-service searches using voice commands, converting audio data to textual data, and transmitting results to a content playback device through a proxy server, allowing users to control IPTV systems via voice commands without the need for complex typing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual keyboard is used on a hand-held device for input, then the device can accept text input, but the typing process becomes significantly more difficult and time-consuming
Solution Approach 1:
The patent replaces the mechanical typing process on a virtual keyboard with a voice recognition system. The voice-to-text engine converts spoken words directly into text commands, eliminating the need for manual keyboard interaction on hand-held devices. This substitution dramatically reduces the time and effort required for text input while maintaining accurate communication with the IPTV system.
2Ease of operation
If a second display device is used for voice input, then user convenience is improved, but the system complexity increases
Solution Approach 1:
The patent leverages the existing multi-functionality of second display devices (smartphones, tablets) that users already possess. These devices serve dual purposes: as the primary interface for the IPTV system and as voice input devices. By utilizing the built-in microphone and processing capabilities of these ubiquitous devices, the system avoids adding dedicated voice input hardware, thereby reducing overall system complexity while maintaining enhanced user convenience.
3Ease of operation
If voice commands are implemented for search functions, then the ease of operation is improved, but the reliability of accurate command recognition may be compromised
Solution Approach 1:
The patent introduces a proxy server as an intermediary between the voice input device and the IPTV system. This proxy server receives voice commands, converts them to text through a voice-to-text engine, and then processes the text commands before executing them on the IPTV system. This intermediary layer allows for command validation, error correction, and standardized processing, thereby maintaining high reliability in command recognition while preserving the ease of voice-based operation.

AI summary
Apparatus and methods to implement a technique for using a second display with a network-enabled television. In one implementation, this feature allows the user to conveniently enter search terms and other commands for control of their IPTV device directly from a second display device using voice commands. Such is particularly convenient when the second display is a device such as a smart phone or tablet computer with limited display space for user data entry.
