JEG-Hybrid
2
JEG Full database AGH database with additional packet loss HRCs AGH database of coding conditions JEG264HMIX1
3
Database available Subjective database – PVSs – HMIX1 & HMIX 2 – PCAP – Subjective MOS + individual ratings – Objective MOS (Inigo)
4
Software tools VirtualBox image – Encoders jm, x264 – Decoders jm, ffmpeg – Packet loss generation Sirannon – Analysis H264AnnexBExtraction JM Inigo objective model
5
Limiting storage & transmission space Storage of PVSs – Lossless encoding (ffmpeg/x264) – MD5 sums for decoded files HMIX (XML) files – Bzip2 PCAP, uncompressed all part of the Virtualbox toolchain
6
SRC Selection SRCs – VQEG HDTV sequences – University of Vienna Gaming/user generated – Animated Sita Sings The Blues Elephants Dream Big Buck Bunny Selection of SRCs?
7
HRC Generation Encoding – List of parameters implemented at AGH Packet loss (who?) – Generate (realistic) scenarios – Obtain/apply packet traces – Decoding with different decoders Error concealment Delay handling
8
Evaluation Objective – Run FR models on our database (JEG264HMIX1) List of available models (who?) Statistical analysis Subjective – Selection of sequences for subjective evaluation
