As　the　development　of　virtual　reality　technology　growing　rapidly,　the　demand　of　delivering　360-degree　panoramic　video　stream　becomes　an　important　task.　High　quality　panoramic　video　is　often　achieved　by　using　high　resolution　and　high　framerates　and　due　to　these　features,　delivering　high　quality　panoramic　video　has　considerable　data　flow,　consuming　large　data　bandwidth　and　computing　power.　To　address　this　problem,　we　introduce　a　novel　streaming　method,　reducing　streaming　data　flow　by　splitting　panoramic　video　into　blocks　and　selectively　deliver　the　blocks　users　see　in　the　panoramic　video　stream,　exploiting　the　fact　that　the　viewer　has　a　limited　field　of　view.　Results　show　that　our　method　effectively　reduces　the　bandwidth　when　delivering　panoramic　video　without　compromising　the　quality　of　the　panoramic　video　at　the　same　time.　©　2022　IEEE.
