Mandate:

1. To collect and coordinate contributions of MPEG-4 video modules described in HDL from Part 2 and Part 10.
2. To continue the analysis of HDL modules for HW acceleration of MPEG-4 part 10 (AVC), to select relevant modules and coordinate development and submission of such selected modules.

4. To evaluate the interfaces of each module so that the specification of common interfaces might enable modules submitted in phase 1 to be directly reused for phase 2.
5. To continue the evaluation of tools suitable to support implementation of phase 2.
6. To proceed with the definition and possible extensions of the MPEG-4 Virtual H/W-S/W Socket that interfaces the HDL modules to the MPEG-4. generically optimized reference S/W part 7 and AVC part 10.
7. To proceed with functionality updates and releases of the MPEG-4 Integrated Framework that interfaces the HDL modules to the MPEG-4 generically optimized reference S/W part 7 and AVC part 10.  
8. To specify reference architectures showing the usage of MPEG-4 Part 9 Reference hardware descriptions in an example application.
9. To continue the development of the reference HW demonstrator.
10. To investigate answers to the call for proposals for reference IDCT implementations that are appropriate for hardware implementations.
