An innovative video coding standard as specified by ITU-T is popularly named as H.265/HEVC (High-Efficiency Video Coding) standard is supported by ISO/IEP Moving Picture Expert Group. The HEVC standard provides tree based structure for compression and individual prediction units (PU) are formed for further processing. HEVC has 35 modes from that 33 modes are angular for intra prediction. In HEVC standard, the individual PU are coded using integer transform, loop filtering and entropy coding. The HEVC standard provides higher compression ratio compared to existing standard.4G Wireless standard is designed to improve the QoS in the wireless cellular network. The paper is focused on compression ratio of HEVC standard and comparison with compression ratio of H.264/AVC is also given. The analysis of BER (Bit Error Rate) is presented by simulation model of transmitting video using H.265/HEVC compression standard over 4g channel.

We designed a SoC/ASIC to implement the low power, high performance H.264 encoder and decoder with a 32-bit RISC CPU on a single chip. We used the system modeling technique to develop the H.264 codec and high-speed RISC microprocessor cores. and adopted the transaction-level based verification technique to do the automatic self-checking, regression testing for the design. The SoC runs the H.264 codec in hardware. It incorporated standard peripheral interfaces, such as UART. USB. 100/10 Mbps Ethernet. IEEE 1394, ATAPI, and SVGA. It supports embedded real-time OS for PDA and wireless applications. It is implemented for complicated Linux operating systems used for personal video recorder, DVD recorder, game and set top boxes, digital camcorders, video conferencing kit, and network computers.
