Multi-Format UHD Transcoder for Uncompressed and Compressed Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems are unable to process both uncompressed and compressed ultra-high definition (UHD) digital broadcast content using a single HEVC transcoder and fail to provide input/output in various formats, including DVB-AVI and IP streams, leading to increased costs and inefficient management of broadcasting equipment.
Innovation Solution
An encoding and transcoding apparatus utilizing a multi-format ultra-high definition high-efficiency codec, which includes processors for handling uncompressed and compressed signals, an HEVC encoder, ASI processor, and IP converter to generate and transmit digital broadcast signals in ASI and IP streams, enabling efficient processing and format conversion of UHD content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional HEVC transcoders are used, then compression performance is improved, but the ability to process both uncompressed and compressed content in a single device is lost
Solution Approach 1:
The transcoding apparatus is designed to perform multiple functions within a single device, including processing both uncompressed and compressed UHD content, supporting various input/output formats (DVB-ASI, IP streams), and providing both encoding and transcoding capabilities. This multi-functional design resolves the contradiction by enabling one device to handle diverse content types and formats that previously required separate equipment.
2Productivity
If separate encoder and transcoder equipment are used, then processing capability is maintained, but equipment costs increase and management becomes difficult
Solution Approach 1:
The patent combines previously separate encoder and transcoder functions into a single integrated transcoding apparatus. This merging maintains full processing capability for both uncompressed and compressed content while reducing the number of required devices, thereby lowering equipment costs and simplifying management. The unified device architecture eliminates the need for multiple separate pieces of equipment.
Solution Approach 2:
The integrated apparatus provides universal functionality to handle various content types (uncompressed and compressed), multiple formats (DVB-ASI, IP streams), and different operations (encoding and transcoding). This multi-functionality ensures that processing capability is maintained across all operations while using a single device instead of multiple specialized devices.
3Adaptability or versatility
If multiple formats are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The transcoding apparatus is designed with universal support for multiple input and output formats including DVB-ASI and IP streams, as well as handling both uncompressed and compressed UHD content. This format versatility is achieved through a unified processing architecture that can adapt to different content types without requiring separate dedicated hardware for each format.
