H.NGVC / H.265
H.265 or H.NGVC (Next-generation Video Coding) is a hypothetical future ITU-T recommendation for video compression coding under study for potential development by the ITU-T Video Coding Experts Group (VCEG). The study of potential technology advances which will enable creation of H.265 is a major part of the current work of VCEG. H.265 is a long-term video coding standard, launched by VCEG. As indicated in ITU-T SG16’s homepage, VCEG plans to complete the requirement definition and begin the detailed algorithm design for H.265 in the study period 2005-2009, and if the progress in contribution technology is sufficient, H.265 is expected to be finalized in 20010-2012.
Currently, H.265 hasn’t been formalized and VCEG keeps seeking proposals and information regarding the possibility of a major gain in performance to justify the step from H.264 to H.265. Though the necessary scope of H.265 is yet to be determined, it is agreed that among the goals will be [AA01]:
- simplicity and “back to basics” approach
- high coding efficiency, e.g., two times compared with H.264
- computational efficiency, considering both encoder and decoder
- loss/error robustness
- network friendliness
- other considerations as necessary
Backward/forward compatibility is not assumed to be required for H.265, as H.265 is a brand new standard instead of an extension of H.264. Although some agreements about the goals of an H.265 project have been reached, e.g. computational efficiency and high compression performance, the current state of technology does not yet seem mature for creation of an entirely new H.265 standard, and all contributions are modifications to KTA JM11, a reference H.264 encoder by the MPEG/VCEG Joint Video Team. In April 2009, the scope of the project was changed to H.NGVC, with a H.264+ standard being the most likely outcome.
The preliminary requirements for NGVC are bit rate reduction of 50% at the same subjective image quality and computational complexity comparing to H.264 High profile, with computational complexity ranging from 1/2 to 3 times as that of H.264. NGVC should be able to provide 25% bit rate reduction along with 50% reduction in complexity at the same perceived video quality as H.264 High profile.
Features:
- 2-D non-separable adaptive interpolation filter (AIF)
- Separable AIF
- Directional AIF
- "Supermacroblock" structure up to 64x64 with additional transforms
- Adaptive prediction error coding (APEC) in spatial and frequency domain
- Adaptive quantization matrix selection (AQMS)
- Competition-based scheme for motion vector selection and coding
- Mode-dependent KLT for intra coding

Code Quality Vs Time To Market
Having been in the software industry for quite some time, here is my take on this. There two kinds of companies working on softwares Product companies and Services companies. Product companies generate revenue by timely releases of their product to beat competitors. Although quality is important to them but it is not so important that they can spend months/years together to imrove the quality and there by lose their market share. Their strategy is to release the first/alpha version of the product and then fix the bugs based on customer experience. Services companies tend to rely a lot on the code quality as it is their measure of experience. Services company make revenues by servicing the clients and their profit is usually governed by how efficiently they can deliver the product thereby reducing the support/warranty time. This can only be achieved by making sure that the code passes all the acceptance criteria and has undergone several rounds of tests. To make sure that the above goes well, mainitaining the code quality becomes important.
If you have any thoughts on this please feel free to share the same.

Writing a Research Proposal
The proposal should ideally be limited to 300-500 words. This might change according to the university you apply. Each sentence and paragraph in the proposal should be to the point. The research title is important and should refelect the contents of the proposal.
The first para should state the problem that you intend to investigate. It should be concise. Remember if there is no clearly defined problem statement your proposal will become less focused and hence more descriptive.
The second para should define the causes and extent of the problem. Also include some background. It should also be clear as to who faces this problem and under what circumsatnces.
In the next paragraph justify why your topic of research is important to this field or how it will solve the stated problem.
The following paragraph should clearly state the aim of the proposed research. This should a specific statement of intent rather than generalised one.
This section is one of the important of all. In this para you should define the methodology you would follow to complete the project. Will the project involve literature survey, experiments, testings etc?
Finally the proposal should end with stating the expected outcomes of the proposed research.
List all the references at the end of the proposal.
All the best for your research proposal. Share you thoughts and let me know if that could be included or excluded to refine this structure further.

What a Weekend Of EPL!!!
Tevez and Bellamy scored a brace for the manchester blues to leap frog the spurs for the coveted fourth place in EPL. The first goal on the break by tevez was freakish to say the least. But this man is just amazing. Having been back in england only 24 hours before the kick-off and having spent most of the time by his pre-maturely born baby girl says a lot about this mans determination and hard work. Great loss to the reds and a great gain for the blues. Bellamy has been sublime this season. I thought he would head towards the exit door after few training ground bust-ups with Mancini. But he has been putting on good shows and is very popular with the city fans. Hope Mancini can persist with him for a long time.
Arsenal v Stoke was another match filled with controversies. I guess Arsenal sweat whenever they concede a throw in with-in the range if Delap's missiles as they don't have a clue to deal with his amazing throw-ins. Stoke scored on the 7th min comming from a peculiar source...yep Delap throw..showcross cusion header and pugh bungles it home. That was the last cheering moment for the home fans. Arsenal got back into the game with a beautiful header by Bendtner. Then the horror tackle on Ramsey by Shawcross (who had been picked into Capello's squad only hours before) which saw him being sent-off. Shawcross is not a malicious defender (shows by the way he his his face under the jersey after the tackle), but the timing on this tackle was horrific. It bought back the painful memories of long-term injuries to Eboue and Eduardo through such tackles.
Aaron ramsey will be out of the game atleast 6 months. This will give tremendous head ache to Wenger as Denilson (injured) and Wilshire (onloan @ Bolton) are not available. Arsenal did win the tie comfortably in the end but their travel back home would not have been that comfortable.
