Universal Mobile Telecommunications System (UMTS); LTE; Study on Surround Sound codec extension for Packet Switched Streaming (PSS) and Multimedia Broadcast/Multicast Service (MBMS) (V13.0.0; 3GPP TR 26.950 version 13.0.0 Release 13)
The present document investigates the potential user experience benefits of surround audio in 3GPP services. The investigation will be performed as follows: ? Identify and document relevant use cases for surround sound in 3GPP. ? Define design constraints that would need to be met by a surround audio codec extension method for adoption by 3GPP. ? Identify suitable testing methodology for surround sound in relevant use cases of the PSS and MBMS services. ? Define subjective minimum performance criteria that would need to be met in order to motivate the consideration of a surround audio coding extension for adoption by 3GPP. ? Validate the user benefits and the feasibility of the deployment of surround sound for the PSS and MBMS services according to the defined minimum performance criteria@ bit rate and design constraints for all the use cases (such as surround sound speaker set-up and headphone decoding mode) through evaluation of at least one example of surround sound coding methods which may be MPS.
