Ad Mediation Server Real-Time Video Format Transcoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
A substantial percentage of video ad requests go unfulfilled due to available ad content being in formats incompatible with mobile devices, such as FLV format, which mobile devices like iPhones cannot support, leading to unsuccessful video ad delivery.
Innovation Solution
An ad mediation server recognizes incompatible ad formats and transcodes the ad content on-the-fly to a compatible format, providing a substitute URL for streaming to mobile devices, ensuring synchronization with the video player for seamless delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ad content is provided in existing formats (e.g., FLV), then the ad content can be stored and served, but mobile devices cannot play the ad content due to format incompatibility
Solution Approach 1:
The patent applies parameter changes by converting video content from one format (FLV) to another format (H.264/AAC) through transcoding. The transcoder changes the encoding parameters of the video content to match the capabilities of mobile devices, thereby resolving the format incompatibility issue while ensuring reliable ad delivery
Solution Approach 2:
The patent introduces a transcoder as an intermediary component between the ad content source and the mobile device. This transcoder mediates the format incompatibility by receiving FLV content and converting it to mobile-compatible formats, enabling successful ad delivery without requiring changes to either the content source or the device
2Adaptability or versatility
If ad content is transcoded in real-time, then format compatibility is achieved, but system complexity increases
Solution Approach 1:
The transcoder is designed as a universal component that can handle multiple input formats and output formats. By making the transcoder multi-functional, the system achieves format compatibility without requiring separate conversion components for each format pair, thereby limiting the increase in system complexity
3Adaptability or versatility
If ad content is transcoded in real-time, then format compatibility is achieved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-processing and buffering the video content before actual playback. The transcoder begins converting the content in advance, and the system buffers the transcoded output, so that when playback is requested, the content is already ready or nearly ready, reducing the perceived processing time
Solution Approach 2:
The transcoder operates continuously rather than in discrete batches. The transcoding process runs in parallel with other system operations, and the transcoder maintains a continuous pipeline of conversion, ensuring that format compatibility is achieved without interrupting the ad delivery workflow or causing significant delays
Data Source
AI summary
The technology disclosed relates to filling video ad requests with video ad content that begins in a format incompatible with the mobile device that is requesting the ad content. In particular, it relates to accessing available on ad content, transcoding the ad content to a video stream and publishing the video stream to the mobile device that requested the head content. This sometimes requires synchronization between a player on the mobile device and the video stream transcoder.
