JEG-Hybrid
JEG Full database
AGH database with additional packet loss HRCs
AGH database of coding conditions
JEG264HMIX1
Database available
• Subjective database– PVSs– HMIX1 & HMIX 2– PCAP– Subjective MOS + individual ratings– Objective MOS (Inigo)
Software tools
• VirtualBox image– Encoders • jm, x264
– Decoders • jm, ffmpeg
– Packet loss generation• Sirannon
– Analysis• H264AnnexBExtraction• JM• Inigo objective model
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
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?
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
Evaluation
• Objective– Run FR models on our database (JEG264HMIX1)• List of available models (who?)• Statistical analysis
• Subjective– Selection of sequences for subjective evaluation
