---->>>A) is h.264 and ---->>>B) is h.265<br />1)INTRODUCTION:<br />-->>A)MPEG 4 Part 10 AVC (Introduced in 2004).</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
-->>B)MPEG-H, HEVC, Part 2 (Approved in Jan 2013 ).</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
2) PROGRESSION:<br />-->>A)Successor to MPEG-2 Part .</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
-->>B)Successor to MPEG 4 AVC, H.264.</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
3) SPECIFICATION:<br />-->>A)Support Up to 4K (4,096×2,304)<br />             Supports up to 59.94 fps<br />             21 profiles ; 17 levels.</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
-->>B)Up to 8K UHDTV (8192×4320)<br />           -upports up to 300 fps<br />            3 approved profiles, draft for additional 5 ; 13 levels.</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
4) COMPRESSION MODEL:<br />-->>A)Hybrid spatial-temporal prediction model<br />         - Flexible partition of Macro Block (MB) , sub MB for motion estimation<br />         - Intra Prediction (extrapolate already decoded neighboring pixels for prediction)<br />         - Introduced multi-view extension<br />           9 directional modes for intra prediction<br />         - Macro Blocks structure with maximum size of 16x16<br />         - Entropy coding is CABAC and CAVLC.</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
-->>B)Enhanced Hybrid spatial-temporal prediction model<br />          - Flexible partitioning, introduces Coding Tree Units (Coding, Prediction and                               Transform Units -CU, PU, TU)<br />          - 35 directional modes for intra prediction<br />          - Superior parallel processing architecture, enhancements in multi-view coding                            extension<br />          - CTU supporting larger block structure (64x64) with more variable sub partition                        structures<br />          - Entropy coding is only CABAC.</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
5) DRAWBACKS:<br />-->>A)Unrealistic for UHD content delivery due to high bit rate requirements. Frame rate                  support restricted to 59.94.</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
-->>B)Computationally expensive (~ 300 % + ) due to larger prediction units and expensive              Motion Estimation (Intra prediction with more nodes, asymmetric partitions in Inter              Prediction).</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; margin-bottom: 1em; padding: 0px;">
6) KEY IMPROVEMENTS:<br />-->>A)- 40-50% bit rate reduction compared to MPEG-2<br />             - Led the growth of HD content delivery for Broadcast and Online.</div>
<div class="qtext_para" style="color: #333333; font-family: q_serif, Georgia, Times, "Times New Roman", serif; padding: 0px;">
-->>B)- 40-50% the bit rate reduction at the same visual quality compared to H.264<br />            - Potential to realize UHD, 2K, 4K for Broadcast and Online (OTT).<br />              This obove points will clarify you with both h.264 and h.265 , and according to me                   currently h.264 is over h.265.<br />Hope this helps you.<br />Thanks.</div>
