Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Receiving devices face challenges in decoding ultra-high definition moving images, such as 8K, in real time due to high processing loads, and existing methods require large circuit sizes and increased costs to support multiple multiplexing formats, making concurrent use difficult and costly.
Innovation Solution
A receiving device with a processor that demodulates and converts multiplexed data between different formats, using a converter to change the multiplexing format, and decoders to process the data in real time, allowing for efficient decoding and reduced costs by supporting multiple formats concurrently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple multiplexing formats are individually implemented in a receiving device, then support for various broadcast formats is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal converter that can convert between multiple multiplexing formats (MPEG-2 TS and MMT) using a single converter component. This multi-functional approach allows the receiving device to handle different broadcast formats without requiring separate dedicated circuits for each format, thereby reducing overall device complexity while maintaining versatility.
Solution Approach 2:
The converter acts as an intermediary component that mediates between different multiplexing formats. Instead of implementing separate processing paths for each format, the converter translates between formats centrally, reducing the need for multiple specialized circuits and lowering device complexity.
2Adaptability or versatility
If multiple multiplexing formats are individually implemented in a receiving device, then support for various broadcast formats is improved, but cost increases
Solution Approach 1:
By designing a universal converter that handles multiple multiplexing formats, the patent reduces the total component count and circuit complexity. This multi-functional design lowers manufacturing costs compared to implementing separate dedicated circuits for each format, while still providing broad format support.
3Device complexity
If one decoder is used for decoding ultra-high definition moving images, then device simplicity is maintained, but processing load becomes too high for real-time decoding
Solution Approach 1:
The patent segments the decoding process by dividing the multiplexed data into different streams that can be processed by multiple decoders simultaneously. This segmentation allows parallel decoding of different content or different multiplexing formats, distributing the processing load and enabling real-time decoding of ultra-high definition images without requiring a single overly complex decoder.

AI summary
A receiving device of the present disclosure includes: a first processor that (i) receives a broadcast signal obtained by modulating multiplexed data including at least first multiplexed data in a first multiplexing format, out of the first multiplexed data and second multiplexed data in a second multiplexing format different from the first multiplexing format, (ii) demodulates the broadcast signal received, and (iii) outputs the multiplexed data obtained as a result of the demodulation; and a converter that (i) converts, into the second multiplexing format, a multiplexing format of the first multiplexed data included in the multiplexed data that has been output, and (ii) outputs converted data obtained as a result of the conversion.
