Digital TV Receiver IoT Control via Transport Stream Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoT control methods do not effectively leverage the interactive features of digital TV signals to synchronize control commands with broadcast content, limiting the immersive user experience and the potential for smart home entertainment environments.
Innovation Solution
The method involves using the Transport Stream (TS) in digital TV technology to transmit IoT control commands synchronized with video content, utilizing PES packets, time stamps, and existing digital TV infrastructure to filter and process these commands for IoT devices, allowing seamless control without requiring changes to the DTV standards or infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DTV signals use existing data broadcast mechanisms to transmit IoT control commands, then control synchronization with broadcast content is achieved, but the interactive features of digital TV remain underutilized
Solution Approach 1:
The patent applies universality by enabling the DTV system to serve multiple functions: traditional video/audio broadcasting and IoT device control. The transport stream is enhanced to carry both entertainment content and control commands through existing data broadcast mechanisms, allowing the same infrastructure to support both conventional TV viewing and smart home control synchronization
Solution Approach 2:
The patent implements preliminary action by pre-synchronizing control commands with broadcast content during the transport stream construction. Time stamps are embedded in advance within the stream, allowing the receiving device to anticipate and prepare for control actions before they are executed, ensuring seamless synchronization without real-time processing delays
2Productivity
If synchronized IoT control data is added to the DTV signal, then control commands can be transmitted through existing infrastructure, but the complexity of filtering and processing data increases at the receiver side
Solution Approach 1:
The patent applies segmentation by dividing the transport stream into distinct components: video data, audio data, and control command data. Each component is processed and filtered separately at the receiver, allowing the complex data stream to be managed through modular processing stages rather than requiring simultaneous analysis of all data types
Solution Approach 2:
The patent introduces an intermediary layer in the form of standardized data packets that bridge the broadcast infrastructure and IoT devices. These packets contain structured control commands with embedded time stamps and device identification, serving as a mediator that simplifies the interface between the complex broadcast system and diverse IoT devices, reducing receiver processing burden
3Ease of manufacture
If existing digital TV infrastructure is used for IoT control, then no changes to DTV standards are required, but the capability to control multiple IoT devices synchronized with content is limited
Solution Approach 1:
The patent enhances universality by designing the control command structure to support multiple device types and protocols within the same broadcast framework. The transport stream can carry parallel control streams for different IoT devices, each with appropriate time stamps and command parameters, allowing a single broadcast infrastructure to control diverse smart home ecosystems simultaneously
Solution Approach 2:
The patent adds a temporal dimension to the control capability by embedding time stamps within the transport stream structure. This allows control commands to be synchronized not only with content playback but also across multiple devices, creating a time-coordinated control environment that extends the basic broadcast function into the smart home control domain
Data Source
AI summary
Method to control IoT devices (e.g. smart lamps, smart air conditioner, etc.) through a smart DTV device. Main control is synchronized with the video scene of the transport stream (open/cable/satellite DTV channel) through data added by broadcaster. The broadcaster chooses the desired IoT devices that will be controlled by the channel and the effects that will be reproduced on all devices. The broadcaster can use some multiplexing tool to add the commands synchronized with the desirable video scene together with the other data present at TS flow. The broadcaster datacasts certain data to all home DTV appliances or receivers tuned to that channel. In the receiver side, this data is filtered, processed and transmitted to all IoT devices on the home network and, also paired with the TV receiver.
