Video Dissemination Server Format Conversion

Solution Overview

Problem

The existing methods for transmitting video files over mobile communications networks are time-consuming and often result in compatibility issues due to different video file formats and operating systems, requiring users to open multiple applications and handle various formats manually.

Innovation Solution

A server system that stores video files and subscriber records, including format and access indicators, automatically generates and transmits video messages in compatible formats to mobile subscribers, reducing the need for multiple applications and ensuring format compatibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual video file transmission methods are used, then users can send video files, but the process is time-consuming and requires multiple applications

Engineering Contradiction:

Improvevideo transmission speedVSAvoidtime for file selection and format conversion

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The server pre-converts video files into multiple formats (MP4, AVI, WMV, FLV) and stores them in a database before receiving transmission requests. When a user sends a video, the system automatically selects the appropriate pre-converted format based on the recipient's device type, eliminating the need for real-time format conversion and manual file selection.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a server as an intermediary between the sender and recipient. The server receives the original video file, converts it into multiple compatible formats, stores the converted versions, and automatically transmits the appropriate format to the recipient's device. This intermediary handles all the complex format conversion and selection processes automatically.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If video files are transmitted in original format, then transmission is simple, but compatibility issues arise with different operating systems

Engineering Contradiction:

Improvevideo format compatibilityVSAvoidsystem complexity for format conversion

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The server pre-converts video files into multiple formats (MP4, AVI, WMV, FLV) and stores them in a database before receiving transmission requests. When a user sends a video, the system automatically selects the appropriate pre-converted format based on the recipient's device type, eliminating the need for real-time format conversion and manual file selection.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the parameter of video format by converting the original video into multiple different formats simultaneously. The server modifies the video's format parameter based on the target device's requirements, ensuring compatibility across different operating systems (iOS, Android, Windows Mobile) without adding complexity to the user's device.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If automatic format conversion is implemented, then compatibility is improved, but server processing requirements increase

Engineering Contradiction:

Improvevideo format compatibilityVSAvoidserver processing power

Core Design Contradiction:

Adaptability or versatilityVSPower

Solution Approach 1:

The server pre-converts video files into multiple formats (MP4, AVI, WMV, FLV) and stores them in a database before receiving transmission requests. When a user sends a video, the system automatically selects the appropriate pre-converted format based on the recipient's device type, eliminating the need for real-time format conversion and manual file selection.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of converting to all possible formats, the server converts to a limited set of common formats (MP4, AVI, WMV, FLV) that cover the majority of mobile devices. This partial conversion approach reduces server processing requirements while still achieving high compatibility across different operating systems and device types.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A server for disseminating a video file to mobile subscriber over a mobile communications network is disclosed. The server comprises a processor programmed for storing a record for each mobile subscriber, defining a criteria for selecting mobile subscribers for videos, wherein said criteria is based on data from a record for a mobile subscriber, selecting a group of mobile subscribers by identifying the records that match said criteria, generating, for each mobile subscriber of the group, a video message in a format that corresponds to the operating system indicator and the video format indicator for said mobile subscriber, and transmitting a video message to the mobile phone number in the record, wherein the video message is transmitted according to the method of access indicator for said mobile subscriber.
