Non-destructive File-based Mastering for Localized Broadcast Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating localized audio-video content for international markets require significant storage and recreate new versions for different broadcast standards, as they are locked to specific resolutions and aspect ratios, leading to inefficiencies and redundant content creation.
Innovation Solution
A non-destructive file-based mastering approach that utilizes metadata to derive localized versions from a domestic source, allowing for independent resolution and aspect ratio, and generates multiple deliverables from a single domestic source, reducing storage needs and enabling broader broadcast master creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full copies of each localized version are stored, then content availability for different broadcast standards is ensured, but storage space consumption increases significantly
Solution Approach 1:
The localized version is segmented into two components: a master copy at the original resolution and aspect ratio, and a separate set of instructions (metadata) containing edit decisions, time codes, and localization parameters. This segmentation allows the system to store only one master copy while generating multiple broadcast-standard-specific versions on-demand, dramatically reducing storage space while maintaining content availability.
Solution Approach 2:
Instead of storing multiple full copies of localized versions for different broadcast standards, the system creates copies only when needed by applying the stored instructions to the master copy. This on-demand copying approach eliminates the need for pre-storing multiple versions, reducing storage requirements while ensuring content availability when required.
2Manufacturing precision
If localized versions are created locked to specific resolutions and aspect ratios, then broadcast standard compliance is achieved, but flexibility for creating versions in different formats is lost
Solution Approach 1:
The system dynamically adapts the master copy to different broadcast standards by applying stored instructions with time codes and edit decisions that specify how to modify the content for each target format. This dynamic approach allows the same master copy to be flexibly transformed into multiple formats (different resolutions, aspect ratios, and broadcast standards) without being locked into a single configuration, thereby achieving both compliance and versatility.
Solution Approach 2:
The system changes key parameters (resolution, aspect ratio, frame rate) of the master copy based on stored instructions to generate versions compliant with different broadcast standards. By storing the original master at high quality and applying parameter transformations through the instructions, the system maintains manufacturing precision for each target standard while preserving adaptability across multiple formats.
3Manufacturing precision
If manual editing is performed for each localized version, then content localization accuracy is improved, but production time and complexity increase
Solution Approach 1:
The system performs preliminary action by capturing edit decisions, time codes, and localization instructions during the initial localization process and storing them as metadata. This preliminary capture of all necessary information allows subsequent versions to be generated automatically without requiring repeated manual editing, thereby maintaining localization accuracy while dramatically improving production efficiency for additional formats.
Solution Approach 2:
The system introduces an intermediary layer of stored instructions and metadata that mediates between the master copy and multiple target formats. This intermediary contains all the localization logic and edit decisions, allowing automatic generation of compliant versions without requiring manual intervention for each format, thus preserving localization accuracy while enhancing productivity.

AI summary
A method, system, apparatus, article of manufacture, and computer program product provide the ability to non-destructively generate a file based master A domestic source (audio and video content) with textless content (have portions of the domestic source that is devoid of text) is obtained A localized source (e g, localized audio-video) based on the domestic source is received The localized video is compared to the domestic source to determine differences The localized video is bladed and realigned with the domestic source. Metadata (of the differences) is transposed onto the domestic source. Texted portions in the domestic source are obscured with corresponding portions of the textless content. Texted material (based on the localized video and texted portions) is created The localized video content and the textless content are discarded The domestic source, localized audio content, created texted material, and metadata are combined into a playlist that represents a localized file based master
