Transcoded Search Resources for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current search engines face challenges in providing seamless and efficient loading of landing page content, particularly in reducing latency and bandwidth usage, while ensuring security and usability across different devices.
Innovation Solution
The system generates transcoded resources with above-the-fold and below-the-fold content, where the above-the-fold content is included in the search results page, allowing immediate display without additional network delays, and the below-the-fold content is loaded separately, optimizing bandwidth and security by using different browsing contexts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire landing page content is included in the search results page, then the user experience is improved with no loading delay, but the bandwidth usage and response time increase significantly
Solution Approach 1:
The landing page content is divided into above-the-fold and below-the-fold portions. Only the above-the-fold content is embedded in the search results page, while below-the-fold content remains on the original page and is loaded separately when needed. This segmentation reduces the amount of content transferred initially, improving response time while maintaining good user experience for the visible portion.
Solution Approach 2:
The above-the-fold content is extracted from the original landing page and embedded directly in the search results page. This extraction allows the most important content to be displayed immediately without waiting for the full page to load, while the remaining content is loaded on demand.
2Speed
If the entire landing page content is included in the search results page, then immediate display is achieved, but the bandwidth consumption increases
Solution Approach 1:
The content is segmented into above-the-fold and below-the-fold portions. Only the essential above-the-fold content is embedded in the search results, reducing bandwidth consumption. The below-the-fold content is loaded separately when users scroll or interact, optimizing bandwidth usage while maintaining loading speed for critical content.
3Loss of time
If above-the-fold content is embedded in the search results page, then latency is reduced, but the device complexity increases
Solution Approach 1:
The above-the-fold content is prepared and embedded in advance within the search results page structure. This preliminary action ensures that when the search results are displayed, the above-the-fold content is already available, reducing latency without requiring complex real-time processing.
Solution Approach 2:
The system acts as an intermediary by pre-processing and embedding the above-the-fold content during the search results generation process. This intermediary role simplifies the client-side complexity, as the embedding is handled server-side before delivery to the user's device.
4Productivity
If transcoded resources are generated and stored during indexing phase, then query response time is improved, but the preprocessing time and computational resources increase
Solution Approach 1:
The transcoding and content extraction are performed in advance during the indexing phase, before queries are submitted. This preliminary processing creates ready-to-use embedded content that can be quickly served during query responses, improving productivity at the cost of upfront computational resources.
Solution Approach 2:
The system dynamically balances computational resources between indexing and query processing. During indexing, computational resources are allocated to transcode and embed content. During query processing, these pre-processed resources are served efficiently. The system adapts resource allocation based on the operational phase to optimize overall performance.
Data Source
AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transcoding and providing resources. A query is received. A resource is generated, and the resource, when processed by a client device, causes the client device to perform various operations. The operations include displaying a search result having an associated landing page and detecting user interaction with the search result. The operations include, in response to detecting user interaction with the search result, displaying a first portion of the landing page that is embedded within the resource and requesting, over a network, a second portion of the landing page. The operations include receiving the second portion of the landing page, and loading the second portion of the landing page. The generated resource is provided in response to the query.
