Purpose For information
Attachments Output - Draft new Recommendation ITU-T H.CVR-MP “Functional requirements for cloud virtual reality systems supporting multi-path transmission”
Body 
ITU-T Study Group 21, Working Party 4 (WP4/21), Question 9 (Q9/21) would like
to inform you that ITU-T Q9/21 has created at its meeting in Geneva, 6-17 July
2026, the new work item ITU-T H.CVR-MP “Functional requirements for cloud
virtual reality systems supporting multi-path transmission”. It aims to specify
functional requirements for cloud virtual reality systems supporting multi-path
transmission. The scope of this draft new Recommendation includes:

   –    Overview;

   –    Service data processing requirements for cloud virtual reality systems
   supporting multi-path transmission;

   –    Network capability docking requirements for cloud virtual reality
   systems supporting multi-path transmission;

   –    Cooperation and management requirements for cloud virtual reality
   systems supporting multi-path transmission.

This work focuses on achieving coordinated optimization of the network layer,
transport layer, and application layer capabilities to overcome the
transmission bottlenecks and ensure a high‑quality, smooth, and reliable cloud
virtual reality user experience.

ITU-T SG21 kindly asks you to share with us any relevant work, if you have in
these matters. ITU-T SG21 looks forward to keeping continued collaboration with
your organization about multimedia and digital services standardization.
