PROJECT #5:

TITLE : HEVC

High Efficiency Video Coding (HEVC), is a video compression standard, one of several potential successors to the widely used AVC, HEVC offers about double the data compression ratio at the same level of video quality as the predecessor and supports high resolutions. Greater efficiency means video can be shown at the same quality while consuming less bandwidth, or bandwidth can be maintained to achieve greater quality.

MODULE #1: INTRA PREDICTION

Description:

In the video, intra-prediction is Predicting the samples for the starting frame of a group of pictures and also some coding blocks in an inter-frame of a video from neighbor blocks in a frame. The Prediction aims to predict the pixels for the current block of a frame without having the reference frame. Adding the predicted pixels with residual pixels to get the original pixels.

Responsibilities:

● Developed several modules for HEVC in C and ARM Assembly level Language.

● Involved in the Analysis, Design, and Implementation phases of the entire project.

● Integrated some modules in reference code to validate the performance.

● Optimized every module in various aspects.

● Analyzed and improved video performance using different tools (Cal grind, Vtune analyzer)

● Orchestrated with Instruments tools (Val grind, Visual Studio.,) extensively at the end of the development cycle to minimize memory leaks and assure overall project stability.

PROJECT #6:

Title : AVC Decoder (H264 Video Decoder)

Description:

H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding) is a video codec specification (ISO/IEC 14496-10). H.264 is used in applications like HD DVD, Blu-ray Discs, videos from YouTube, and the iTunes Store.

MODULE #1: CAVLC

Description:

CAVLC is a Lossless compression technique used in AVC to encode residual, Zig-Zag order, blocks of transform coefficient and is designed to take advantage of several characteristics of quantized blocks. It is supported in all H.264 profiles.

Responsibilities:

● Study of H264 video specification.

● Optimization of memory and MIPS.

● Implementation of CAVLC for H.264.

PROJECT #7:
