6. OBJECTIVE
The goal of this project is to compare the performance of the HEVC and H.264 decoders in various profiles, using different sequences and in different resolutions.

7. ABOUT HIGH EFFICIENCY VIDEO CODING (HEVC) [43]
HEVC is the latest video coding standard jointly presented by ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group.
The main advantage of HEVC is that it reduces the bit rate by 50% compared to the existing video coding standards at the same time giving equal perceptual quality.

12. How does an H.264 codec work ?
An H.264 video encoder carries out prediction, transform and encoding processes to produce a compressed H.264 bitstream. An H.264 video decoder carries out the complementary processes of decoding, inverse transform and reconstruction to produce a decoded video sequence.

15. PROFILES USED FOR COMPARISON
The profiles that will be used for comparison in HEVC will be all-intra, main and main 10.
The profiles that will be used for H.264 will be high and high 10.

16. VIDEO RESOLUTIONS USED FOR COMPARISON

17. SOME ADDITIONAL INFORMATION
HEVC decoders, that consume low power, have been implemented on hand held devices by few companies. [58]
When the same HEVC decoder implemented in HM, is made of low power decoder by modifying few components, then it can be used as low power decoder for handheld and mobile devices. [59]
