Review of M32174

• 
  [Technical review]
  
  • 
    It was reviewed in the Adhog meeting on Sunday
    
• 
  [Prior art review]
  
  • 
    Variable transform block size (Type-1 A)
    

• 
  The relevant prior art “adaptive transform coding using variable block size” was issued on 1989 and the patent described the use of variable transform block size and its signaling within intra mode.
  
• 
  It was reported that the use of variable transform block size was considered as Type-1 A technology.
  

• 
  Intra prediction (Type-1 B)
  

• 
  It was reported that the use of the directional intra prediction in video coding was disclosed on Oct. 1998.
  
• 
  The proponent had not found the relevant patents.
  
• 
  The use of variable transform block size was considered as Type-1 B technology.
  

• 
  Combination variable transform block size with intra prediction (Type-1 B)
  

• 
  The proponent had not found the relevant patents.
  
• 
  Although the use of variable block size was Type-1 A, the combination variable transform block size with intra prediction was considered as Type-1 B technology due to the intra prediction.
  

• 
  [Recommendation]
  
  • 
    To adopt the technology into ITM 8.0.
