  2. Demo: Bitstream/Baseband capturing system • Capturing system based on VLC media player • Captured data • RTP with depacketized time (not in PCAP format) • MPEG-2 TS • MPEG-2 PES (packetized ES) • Baseband with playback time VLC (sender) VLC (Receiver) Audio MPEG-2 Audio Decoder Audio Output Module UDP/IP⇒RTP RTP⇒ MPEG-2 TS MPEG-2 Demultiplexer MPEG-2 Video Decoder Video Output Module (DirectDraw) Video raw TS data (time-aligned) raw PES data (time-aligned) Baseband data (YUV 4:2:0) with timestamps raw RTP data with timestamps

  3. Demo: Bitstream/Baseband capturing system • Restrictions • Currently available only for MPEG-2/TS/RTP/UDP streaming • H.264 capturing: under development • Information related to audio is not captured at all • RAMDisk is required: need HUGE capacity for HD. VLC (sender) VLC (Receiver) Audio MPEG-2 Audio Decoder Audio Output Module RTP over UDP UDP/IP⇒RTP RTP⇒ MPEG-2 TS MPEG-2 Demultiplexer MPEG-2 Video Decoder Video Output Module (DirectDraw) Video raw TS data (time-aligned) raw PES data (time-aligned) Baseband data (YUV 4:2:0) with timestamps raw RTP data with timestamps
