Client Push Instruction for Omnidirectional Video Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in transmitting omnidirectional video data as clients may not support specific projection methods, leading to playback issues and increased load due to conversion processing, and servers may transmit unsuitable projected video data.
Innovation Solution
An information processing apparatus that generates and transmits a push instruction to a server, specifying suitable projection methods for the client, allowing the server to project and segment omnidirectional video data accordingly, ensuring the client can play back the data efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the server pushes omnidirectional video data to a client using a specific projection method, then the playback delay is reduced, but the client cannot play back the video data if it does not support the specific projection method
Solution Approach 1:
The client performs preliminary action by generating a push instruction that specifies the projection method it supports before receiving video data. This allows the server to prepare and push appropriately formatted data, reducing playback delay while ensuring compatibility through advance client capability declaration.
2Adaptability or versatility
If the client converts omnidirectional video data from one projection method to another, then the desired projection method is achieved, but the processing load on the client increases
Solution Approach 1:
Instead of the client converting received video data from one projection method to another (which increases processing load), the approach is inverted: the client specifies its supported projection method in the push instruction, and the server projects the data in the appropriate format before transmission. This eliminates the need for client-side conversion processing.
3Productivity
If the server transmits omnidirectional video data that has been projected using a specific projection method, then the data is ready for immediate playback, but the client cannot display the data if it does not support the specific projection method
Solution Approach 1:
The client provides feedback to the server by including projection method identification information in the push instruction. This feedback mechanism allows the server to adapt its data projection and transmission format to match the client's capabilities, ensuring both transmission efficiency and client compatibility.

AI summary
An information processing apparatus that receives image data from a server apparatus, comprising: a generation unit configured to generate a push instruction that includes identification information regarding one or more projection methods of a plurality of projection methods that are applicable to a projection target image; a transmitting unit configured to transmit a push instruction generated by the generation unit to the server apparatus; and a receiving unit configured to receive image data pushed from the server apparatus in response to a push instruction transmitted by the transmitting unit, the image data being generated by projecting a projection target image, using a projection method that is decided based on identification information that is included in the push instruction.
