When bypass live broadcast of Real-Time Communication (TRTC) is enabled, the domain name does not necessarily need to be registered for use in all cases.
For instance, if you are using some cloud platforms' services that offer TRTC functionality within their own ecosystem and allow for direct configuration using internal identifiers or IP addresses without requiring a custom domain name registration through a third-party domain name registrar, then you might not need to register a separate domain name.
However, if you want your TRTC live broadcast to be accessible via a more user-friendly and memorable custom domain name, or if you need to integrate it with other external systems or services that rely on domain names for routing or identification, then registering a domain name would be necessary.
For example, if you are using Tencent Cloud's TRTC service and want to expose your live broadcast to users through a custom domain like "live.yourcompany.com", you would need to register "yourcompany.com" (or a subdomain of it) with a domain name registrar and then configure DNS records to point to Tencent Cloud's servers handling the TRTC traffic.
In summary, while it's not always mandatory to register a domain name for TRTC bypass live broadcast, doing so can provide benefits in terms of branding, user experience, and integration with other systems.
