Media Object Sample Encapsulation for Efficient Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accessing and managing digital media content from devices like digital camcorders, as existing technologies lack efficient methods to represent and retrieve media objects without predefined samples, making it hard to view or manipulate content, especially when devices contain large quantities of media objects.
Innovation Solution
A system and method that encapsulates a representative sample of media objects, including metadata and properties, allowing for flexible identification and transmission of samples, even when the original content does not store such representations, ensuring compatibility with various playback devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complete media object is stored and transmitted, then the content is complete and accurate, but the transmission time and processing overhead increase significantly
Solution Approach 1:
The patent extracts a representative sample from the complete media object and stores it as a separate property in the media object metadata. This sample can be transmitted and viewed independently without requiring the entire media object, thus reducing transmission time while maintaining content representation accuracy.
Solution Approach 2:
The representative sample is generated and stored in advance as a property of the media object. When the media object needs to be accessed or transmitted, the pre-generated sample can be immediately used for preview or identification purposes without waiting for the complete media object to be processed or transmitted.
2Ease of operation
If a representative sample is generated and stored as a property, then content identification and preview become possible, but the media object structure becomes more complex
Solution Approach 1:
The representative sample property serves multiple functions: it enables content identification, provides preview capability, facilitates quick searching, and supports media object verification. This multi-functionality justifies the additional data structure complexity by delivering multiple operational benefits from a single added property.
3Ease of manufacture
If the first few frames are used as default sample, then sample generation is simple, but the sample may not be representative of the entire media content
Solution Approach 1:
The system automatically analyzes the media object content to identify and select the most representative sample without requiring manual intervention. The sample selection process self-adjusts based on content characteristics, balancing automation simplicity with representative accuracy.

AI summary
A system and related techniques relate to the retrieval of a media object list with associated properties from a media device such as a digital video camcorder, audio player or other source or device. According to embodiments the retrieved list or set of media objects and their attributes or properties, for example a song list along with song length, codec, artist and other information may be retrieved from the source device, along with a representative sample of the media or content of each object. So the title which identifies a song may be accompanied by a short sound clip of a representative sample of that song, or a title identifying a digital video movie may be accompanied by a short video clip of an introductory portion of that movie. According to the invention in one regard, that representative sample may be generated in the source device and encapsulated into the set of properties which are passed with the object identifier to an initiator device, such as a user's computer accessing a video camera for downloading. A media object which is stored in monolithic binary format with no predetermined internal samples may nevertheless be accessed and sampled to allow a user to view or listen to representative content, through encapsulation of a sample in the properties passed via an underlying media transport protocol.
