Universal Transcoder Selecting Signal Multi-Format Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transcoding systems are inefficient as they can only send a service provider signal to one transcoder at a time, making it cumbersome to handle complex requirements for multiple signal outputs, and lack dynamic authentication for downstream receivers.
Innovation Solution
A system with a transcoder device that receives an input signal and uses a selecting signal to output the signal in multiple formats, featuring a receiver, decoder, transcoder, and transmitter portions, allowing remote configuration and authentication for secure distribution to various devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional integrated receiver decoders are used to transcode signals, then signal format conversion can be achieved, but the system complexity increases and efficiency decreases when handling multiple output formats
Solution Approach 1:
The patent implements a universal transcoder system that can output multiple formats (MPEG-2, MPEG-4, H.264, etc.) through a single device. The transcoder includes multiple transcoder portions, each capable of converting to different formats, allowing one system to serve multiple distribution channels (satellite, cable, internet, mobile) without requiring separate transcoding equipment for each format.
Solution Approach 2:
The transcoder system is divided into multiple independent transcoder portions (first transcoder portion, second transcoder portion, etc.), each handling a specific output format. This segmentation allows parallel processing of different formats from a single input signal, improving efficiency while maintaining the ability to handle multiple formats simultaneously.
2Reliability
If multiple versions of content are created and distributed securely, then content protection is improved, but the productivity and distribution efficiency decrease
Solution Approach 1:
The system performs preliminary transcoding of the content into multiple formats before distribution. The transcoder portions prepare all necessary format versions in advance, and the selecting signal mechanism pre-configures which formats will be distributed to which devices. This eliminates the need for real-time format conversion and reduces the burden of managing multiple content versions.
Solution Approach 2:
The patent introduces an intermediary selecting signal mechanism that sits between the content source and multiple distribution channels. This intermediary receives the original content, determines the appropriate output formats based on device capabilities, and routes the content through the appropriate transcoder portions. This mediator simplifies the distribution process by centralizing format selection and conversion logic.
3Adaptability or versatility
If third party tools are used for transcoding, then format conversion capability is achieved, but the device complexity and operational ease worsen
Solution Approach 1:
The patent combines multiple transcoder functions into a single integrated transcoder device. Instead of using separate third-party tools for each format conversion, the system merges MPEG-2, MPEG-4, H.264, and other transcoder capabilities into one unified device that can handle all format conversions internally. This integration simplifies operation by providing a single point of control for all transcoding needs.
4Device complexity
If a single transcoder handles one output format at a time, then the device complexity is reduced, but the productivity and speed of handling multiple formats decreases
Solution Approach 1:
The transcoder is segmented into multiple parallel transcoder portions, each dedicated to a specific output format. This allows the system to process multiple formats simultaneously from a single input signal, dramatically improving productivity. The selecting signal mechanism enables the system to activate only the necessary transcoder portions based on the required output formats, maintaining manageable complexity while achieving parallel processing capabilities.
Data Source
AI summary
A device is provided for use with an input signal and a selecting signal. The input signal has a first format, and the selecting signal has a first state and a second state. The device comprises a receiving portion and a transcoder portion. The receiving portion can receive the input signal and output a received signal. The transcoder portion is arranged to receive the selecting signal and can output a first transcoded signal when the selecting signal is in the first state and can output a second transcoded signal when the selecting signal is in the second state. The first transcoded signal is based on the received signal and is in a second format. The second transcoded signal is based on the received signal and is in a third format, wherein the first format is different from the second format, the first format is different from the third format and the second format is different from the third format.
