6 Run Encoding 6 Sample Batch File (e.g. Windows 7)./Encoding.cmd Description of Batch Command SET ProjectPath=###pathname to the software package### SET BinaryExecutable=###pathname to the encoder's binary executable### SET SeqPath=###pathname to the common test sequences### SET SeqID=###alias of test sequence to be encoded (will be described later)### SET TestCondition=###alias of common test condition (will be described later)### SET QP=###quantization parameters### SET FramesToBeEncoded=###the number of frames to be encoded### SET TransformSkip=###turn on/off transform skip (0:off; 1:on)### Output Files str.bin (bitstream) rec.yuv (reconstructed sequence)

9 Run Decoding 9 Sample Batch File (e.g. Windows 7)./Decoding_YUV.cmd for YUV sequences./decoding_rgb.cmd for RGB sequences Description of Batch Command SET DecoderBin=###pathname to the decoder's binary executable### SET Bitetream=###pathname to the bitstream to be decoded### SET OutputYuv=###pathname to the decoded sequence### Decoding Output dec.yuv (decoded sequence) for YUV sequences dec.rgb (decoded sequence) for RGB sequences Note that decoded sequence MUST be identical to rec.yuv

10 Example 10 Sample Case Bitstream to be decoded :.\str.bin Filename of decoded sequence to be:.\dec.yuv Sample Commands SET DecoderBin=.\HM 10.0+RExt 2.0\bin\vc9\x64\Release\TAppDecoder.exe SET Bitetream=.\str.bin SET OutputYuv=.\dec.yuv

13 Common Test Conditions (1/2) 13 Common Test Platform HM 1.0+RExt 2.0 Coding Structure and Profile All Intra and Main Profile: AILC Low Delay and Main Profile: LPLC E.g. SET TestCondition=AILC (see pp. 7) Quantization Parameters Main tier (MT) : 22, 27, 32, 37 High tier (HT) : 17, 22, 27, 37 Super high tier (SHT): 12, 17, 22, 27 Note that 6 QPs (12, 17, 22, 27, 32, 37) in total are required

22 Mandates (1/2) 22 #1. Generate Anchor Bitstream (10%) Produce anchor bitstreams under common test conditions Fill encoder s & decoder s reports into excel template Report bitrate & rate saving relative to raw data when PSNR approaches to (a) 40 and (b) 50 (note: you may need to observe the rate psnr curve) #2. Produce Perceptual Observations (40%) Identify visual artifacts at QP37 (Reference: JCTVC M0320) Identify at which rate point that the artifacts diminish Identify at which rate point that the decoded sequences are visually identical to their corresponding raw data

SET TransformSkip=0 (see pp. 7) Fill encoder s & decoder s reports into excel template Report BD rate savings Report bitrate & rate saving relative to raw data when PSNR approaches to (a) 40 and (b) 50 (note: you may need to observe the rate psnr curve) Repeat mandate #2

24 Submission Requirement 24 A Report Detailed discussion on the reported results is a MUST An Excel File All the cyan cells in the given template should ALL be filled General Information Due date: May 22, 2013 Penalty for overdue submission: 30% Note that generating 240 rate points (120 for each Mandate #1 & #3) will consume a huge amount of computation power Roughly 400 hours are required for a single computer equipped with Intel i7 860 CPU and 16GB RAM
