Videos on mobile devices ò YouTube, Netflix, Facebook, Google,Vevo, Vimeo, are all reaching the mobile devices ò What about Digital Terrestrial Television? DTT2IP ? ò x
Our GOAL: DTT2IP
Implementation
Implementation RF DVB-T MPEG-2 TS IP MPEG-2 TS
Our contribution ò Have an open source solution, from which everybody can benefit ò Make available on any hardware platform: Linux / Windows PC (with VM installed) ò Synology NAS ò Raspberry Pi ò Wi-Fi router ò ò Provide good and stable TV services
DTT2IP - problems ò Which transport protocol to use: ò RTP/UDP vs. HTTP/TCP ò Architecture for the discovery protocol: ò SAT>IP/SSDP vs. DLNA/UPnP ò Client applications/decoders ò DVB features
DTT2IP v1.0 Unicasted RTP for transport protocol ò DVBlast(VLC) as a video streamer ò SAT>IP: 1. SSDP server for the discovery protocol ò 2. RTSP server for the management/control of DVBlast SSDP server UDP SSDP server DVBlast RTP stream RTSP
DTT2IP v1.0 - Results Pros Cons Multiple streaming to different users Unsupported / Poor video quality for HD TV programs Good video quality for SD TV programs Scanning for services takes long time DVB-T features (EPG, subtitles, No support for all devices (Windows Teletext) phones, TV sets, PC ) 2 Client applications available (Elgato No transcoding available and Tivizent) No multicast available
DTT2IP v2.0 Unicasted HTTP/TCP for the transport protocol ò MuMuDVB as a video streamer ò DLNA/UPnP server: 1. For the discovery on the network ò 2. For the management / control of MuMuDVB UDP TCP stream
DTT2IP v2.0 - Results Pros Cons Multiple streaming to different users More bandwidth (~240Kbps) Good quality for SD TV programs More overhead compared with RTP Improved quality for HD TV programs No DVB-T features Scanning of services is done only More processing power required once (~1min) Supported by all of the devices Transcoding now available More then 2 applications available
Future work ò Have a stable and compatible UPnP server ò Implement transcoding, and MPEG-DASH, HLS ò Have DLNA clients displaying DVB-T features (i.e. EPG, Subtitles, Teletext, HbbTV)
Question?
Thank you!
