Smart TV Dongle HDMI Input for Wireless Cable TV Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart HDMI TV dongles lack an HDMI input terminal, preventing the wireless sharing of high-definition cable TV programs or video from external high-definition cable TV set top boxes or video players with smartphones or tablets.
Innovation Solution
A method and device that utilize a Bluetooth learning remote controller to control a high-definition cable TV set top box, a smart TV dongle with dual HDMI terminals, and wireless communication protocols like WiFi Direct, Miracast, or Airplay to encode and transmit HDMI signals from the set top box to a smart terminal for playback, allowing control and viewing of TV programs on a smart device anywhere.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart HDMI TV dongle only provides a HDMI output terminal, then the smart phone or tablet computer can transmit programs to the TV dongle wirelessly, but the TV dongle cannot support external high-definition cable TV set top boxes or high-definition video players
Solution Approach 1:
The patent applies universality by enabling the TV dongle to perform multiple functions: it can both receive programs from smart devices and receive HDMI signals from external devices like cable TV set top boxes. The dongle acts as a universal receiver that handles both wireless program transmission and wired HDMI input, eliminating the need for separate devices for different functions.
Solution Approach 2:
The patent introduces a HDMI input terminal as an intermediary component that bridges external HDMI devices (cable TV set top boxes, video players) with the smart terminal system. This intermediary allows the dongle to capture HDMI signals from external sources and process them through its encoding and wireless transmission capabilities, enabling compatibility without direct connection between external devices and smart terminals.
2Adaptability or versatility
If the TV dongle receives HDMI signal from external devices, then high-definition cable TV programs can be shared wirelessly with smart phone or tablet computer, but the dongle needs additional HDMI input terminal which increases device complexity
Solution Approach 1:
The patent merges the HDMI input functionality with the existing TV dongle structure. Instead of creating a separate device for HDMI reception, the patent integrates the HDMI input terminal into the dongle itself, combining the functions of wireless transmission and wired HDMI reception in a single compact device. This merging reduces the need for multiple separate components while achieving wireless sharing of cable TV programs.
3Ease of operation
If users watch TV programs on fixed high-definition televisions, then high-definition cable TV programs can be watched with good quality, but other family members may be disturbed and the user will miss moments if leaving during programs
Solution Approach 1:
The patent segments the viewing experience by enabling multiple smart terminals (smartphones, tablets, computers) to simultaneously or alternatively receive and display the same cable TV program content. Instead of a single fixed viewing location, the system divides the content distribution to multiple portable devices, allowing different family members to view programs at different locations without disturbing each other.
Solution Approach 2:
The patent introduces dynamic viewing flexibility by allowing users to move between different locations while watching TV programs on portable smart devices. The wireless transmission capability enables the viewing experience to adapt to user movement, allowing individuals to leave and return without missing program moments, and enabling multiple users to view simultaneously at different dynamic locations throughout the house.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to watch high-definition cable TV programs on smart devices anywhere in the house without disturbing others, with seamless control and minimal delay, supporting protocols like WiFi Direct, Miracast, or Airplay for wireless transmission and playback.
Implementation Method 1
The Bluetooth learning remote controller is communicated with the high-definition cable TV set top box by utilizing infrared ray
Implementation Method 2
the smart TV dongle performing an audio and video encoding and a playing format packing on the HDMI signal and then transmitting the packed signal to the smart terminal by using a wireless manner
Data Source
AI summary
A method for watching high-definition cable TV programs includes: a blue-tooth learning remote controller learning remote-controller controlling instructions of a high-definition cable TV set top box, and uploading the learned instructions to a smart terminal such that the smart terminal controls the high-definition cable TV set top box; the smart terminal controlling the high-definition cable TV set top box to choose high-definition cable TV programs; the high-definition cable TV set top box outputting a HDMI signal; the smart TV dongle receiving the HDMI signal, and outputting the HDMI signal to a high-definition TV; the smart TV dongle performing an encoding and a packing on the HDMI signal and then transmitting the packed signal to the smart terminal by using a wireless manner; and the smart terminal performing a de-packing and a decoding on the received signal and then playing the decoded signal on the smart terminal.
