    The Cloud Streaming Services console provides the Live Video Caster (LVC) system. This document describes how to use LVC for online broadcasting after activating the LVC feature.
    Billable items of LVC include broadcast output duration and third-party relay. Billing based on usage duration is supported. For more information, see Live Video Caster Pricing Overview.
    To avoid incurring unnecessary charges when you are not using a caster, click Stop for the caster on the Live Video Caster list page. For detailed procedures, see Caster Console Management.
    LVC is incompatible with Internet Explorer and Firefox browsers. Use LVC on Chrome.
