Job Responsibilities in Cradle Technologies, Pune:

1. Title: Involved in Implementation of Scalable Rate Control for H.264

Team Size: Two

Operating System: Windows

Language: C

Role: Coder & Individual Contributor.

Description:

This Project Implement Scalable Rate controls for H264 Encoder.

Each Encoded Frame of Video generates variable number of Bits. In order to transmit Variable bit rate on

CBR Channel buffering provided at both Encoder & Decoder end. The rate control module takes care such

that there should not be an Overflow and underflow at decoder & tries to achieve uniform quality by

dynamically adjusting Quantization step. The scalable rate control and frame level lookup table based

algorithms implemented.

The various phases were to implement rate control algorithm In reply to modified JM reference C code.

Later implementing in C code. The final phase was coding, integration & testing.

In addition, I carried out testing for different video sequences of different resolution fo r Variable Bit rate &

determination of tradeoffs between bit rate & video quality.

2. Title: Implementation of PMVFAST motion algorithm for H.264 codec.

This algorithm implemented for prediction of Motion estimation & then compensation of macro block to

achieve compression i.e. exploitation of temporal redundancy. The algorithm involved the LDS & SDS logic

based on the SAD computed. Implemented for the modes (16x16, 16x8, 8x16, and 8x8) & for full pel

Resolution.

Achievement :

Best Employee Award for 5MP Fisheye Camera Project.

Received Numerous client appreciation Mail.

Resolved many Technical issues during Execution Phase
