The activities of ad hoc groups that had been established at the prior meeting are discussed in this section.

givenThe status was presented verbally – the work was generally agreed to be progressing as planned and expected, with (business as usual, no issues of major concern in the progress.)
JCTVC-J0002 JCT-VC AHG report: HEVC Draft and Test Model editing (AHG2) [B. Bross, K. McCann (co-chairs), W.-J. Han, I.-K. Kim, J.-R. Ohm, K. Sugimoto, G. J. Sullivan, T. Wiegand (vice-chairs)]

The seventh High Efficiency Video Coding (HEVC) test model (HM7) was developed from the sixth HEVC test model (HM6), following the decisions taken at the 9th JCT-VC meeting in Geneva (27 April to 7 May 2012).

Two editorial teams were formed to work on the two documents that were to be produced:

JCTVC-I1002 HEVC Test Model 7 (HM 7) Encoder Description

• 
  Il-Koo Kim
  
• 
  Ken McCann
  
• 
  Kazuo Sugimoto
  
• 
  Benjamin Bross
  
• 
  Woo-Jin Han
  

JCTVC-I1003 High Efficiency Video Coding (HEVC) text specification draft 7 [2]

• 
  Benjamin Bross
  
• 
  Woo-Jin Han
  
• 
  Jens-Rainer Ohm
  
• 
  Gary J. Sullivan
  
• 
  Thomas Wiegand
  

Editing JCTVC-I1003 was assigned a higher priority than editing JCTVC-I1002.

An issue tracker (http://hevc.kw.bbc.co.uk/trac) was used in order to facilitate the reporting of issues on the text of both documents.

One version of JCTVC-I1002 and eight successive versions of JCTVC-I1003 were published by the Editing AHG following the 9th JCT-VC meeting in Geneva.

The main changes in JCTVC-I1002 and JCTVC-I1003, relative to the previous JCTVC- H1002, were listed in the report.

The recommendations of the HEVC Draft and Test Model Editing AHG were to:

• 
  Approve the edited JCTVC-I1002 and JCTVC-I1003 documents as JCT-VC outputs
  
• 
  Continue to edit both documents to ensure that all agreed elements of HEVC are fully described
  
• 
  Encourage the use of the issue tracker (http://hevc.kw.bbc.co.uk/trac) to facilitate the reporting of issues with the text of either document
  
• 
  Compare the HEVC documents with the HEVC software and resolve any discrepancies that may exist, in collaboration with the Software AHG
  
• 
  Continue to improve the overall editorial quality of the HEVC draft text specification, to allow it to proceed to DIS ballot
  
• 
  Ensure that properly drafted candidate text for both the HEVC draft text specification and the HM Test Model (if appropriate) is available prior to making any decision to change the HEVC specification
  

The last item above was particularly noted, as a "ratcheting up" of the need for stability and focus on getting things complete, coherent and finalized.

The AHG recommendeds that text should be provided and approved before making a decision for inclusion, as in the previous period some text was arriving quite late in some cases. This was confirmed by group consensus.
