Solution Overview

Problem

The task of locating specific content items within audio/video productions is labor-intensive and time-consuming due to the lack of efficient access methods, particularly with compressed signals stored on linear recording media like video tapes, where operators must review entire tapes to identify desired content.

Innovation Solution

An audio and/or video generation apparatus that includes a meta data generation processor to create and communicate meta data describing the content of audio/video signals separately from the recording medium, allowing for rapid identification and navigation of content items, and an integrated system for planning, acquisition, and editing of audio/video productions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If audio/video signals are recorded on linear recording media (video tapes), then the recording capacity and storage are improved, but the ability to rapidly locate and identify content items deteriorates

Engineering Contradiction:
Improverecording capacityVSAvoidtime to locate content items
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent extracts the identification information (meta data) from the audio/video signals and stores it separately in a database. This allows the actual video content to be stored efficiently on linear media while the identifying characteristics are maintained in a searchable format, enabling rapid content location without reviewing the entire tape.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a database as an intermediary between the linear recording media and the user. The database stores meta data that describes the content of the audio/video signals, acting as a mediator that enables users to search and locate specific content items without physically navigating through the entire recording medium.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If operators visually search through audio/video productions to locate content items, then the accuracy of content identification is improved, but the labor intensity and time consumption increase

Engineering Contradiction:
Improvecontent identification accuracyVSAvoidoperational simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system performs self-service by automatically generating and storing meta data that describes the content of audio/video signals. This eliminates the need for operators to manually review entire tapes, as the system has already created searchable identification information that can be queried automatically.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of visual searching through physical media with an automated information retrieval system. Instead of operators manually scanning tapes, users can query the database electronically to retrieve precise content identification results instantly.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the entire recording medium is reviewed to identify content items, then the completeness of content search is improved, but the productivity of the editing process deteriorates

Engineering Contradiction:
Improvesearch completenessVSAvoidediting speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary action by pre-processing the audio/video signals to extract and store identifying characteristics in the database before the actual editing process begins. This allows editors to search through pre-organized identification information rather than reviewing complete recordings, significantly improving editing speed while maintaining search reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the audio/video content into identifiable units by extracting specific characteristics (meta data) that describe each segment. This segmentation allows the system to store and retrieve individual content items independently, enabling editors to access specific segments without reviewing the entire recording medium.

Inventive Principle:
Principle #1Segmentation

AI summary

An audio and/or video generation apparatus comprises a recording processor which is operable to record audio and/or video signals on a recording medium, a meta data generation processor which is operable to generate meta data identifying the content of the audio/video signals, and a communications processor which arranged to communicate the meta data separately from the recording medium.Furthermore, the meta data generation processor may be operable to generate at least one sample image which is representative of a video image from the recorded video signals, and to associate the sample image with an address on the recording medium at which the video image is recorded. The video and/or audio generation apparatus provides an advantage in generating and utilising meta data to facilitate the generation of audio/video productions. Accordingly, a system for generating an audio and/or video production comprises an acquisition processor operable in use to receive instructions from a user which instructions are representative of a list of content items for the audio and/or video production. The audio and/or video generation apparatus is arranged in use to receive information representative of the list of content items, and to generate audio and/or video signals in accordance with the content items on the list. An ingestion processor may be provided to receive the list of content items, and the audio and/or video signals and to form the audio and/or video production by associating the audio and/or video signals with the list of content items.
