These comparisons usually involve video encoding done for a range of application use-cases (live entertainment, video conferencing, films, etc.) and different bitrates corresponding to certain video test sequences. Several studies have compared the coding efficiency of the H.265 Main Profile (MP) to similar profiles from several existing video standards in use today, including H.264, MPEG-4 AVC, H.263, and H.262. This translates into an ability to encode ordecode video at the lowest possible bitrate while maintaining a defined level of video quality. Today, designing a video coding standard for both mobile and consumer devices is primarily aimed at achieving the highest coding efficiency possible. 3: MPEG-2, H.264 and HEVC/H.265 tools comparison To get a better understanding of the differences between MPEG-2, H.264 and H.265/HEVC, you can find a comparison of the tools employed by each standard in Figure 3.įig. This larger block size allows HEVC to achieve higher compression or higher resolution and improve parallel processing efficiency compared to H.264/MPEG-4 AVC. H.265 (HEVC): larger block sizes enhance encoding efficiency*. HEVC offers variable blocks that can handle up to 64×64 pixels, changing the size according to texture, while the previous generation H.264 standard relied on a macro-block size of a maximum of 16×16 pixels.įig. HEVC divides a frame into small blocks (referred to as "CU" – or "coding units") and the prediction and transformation coding of the images is conducted within each CU. H.265 video coding is an order of magnitude more complex than previous codec implementations.

Multi-stream and 4K are key drivers for hardware HEVC decode and encode, which Imagination's IP has already been designed for. 1: Ittiam demonstrated software-based HEVC decoding at the NAB Show 2013.įor the next generation of products, hardware-based HEVC decode and encode will be necessary to drive the requisite performance while keeping power consumption to a minimum. Companies that have demonstrated software-based implementations include NTT Docomo, Telestream/MulticoreWare, Vanguard Video Solutions, and Ittiam.įig.
#Remux vs hvec 10bit software#
To date, we've predominantly seen software decode solutions for consumer electronics, running entirely on the CPU or using GPU compute to accelerate HEVC decode. Several demonstrations of HEVC are in evidence across the industry.

H.265 is set to be rapidly adopted and deployed by manufacturers and content providers, especially for mobile video distribution and 4K Ultra-HD TV broadcast. It is a direct successor to the highly popular H.264 standard. H.265, also known as High Efficiency Video Coding (HEVC) is a video transcoding standard recently approved and ratified by ITU-T. H.265 (HEVC) – next-generation video coding Plus, with 'beyond real time' HD video handling, video encoders/decoders must provide enough performance for tomorrow's Ultra-HD 4Kx2K applications, such as display surfaces and mosaic screens. With the increasing availability of OLED displays and 10 bit monitors, which offer a wider color range, consumers are demanding higher color fidelity than ever before.
Today's increasingly demanding applications, such as Ultra-HD TV, wireless display, and high quality video capture are driving the need for new video encoding and decoding technologies. April, 2014: Pipeline The Emergence of H.265 (HEVC) and 10-Bit Color Formats
