What Is Codec H.265?

Wednesday, October 04, 2023 | Press Releases

As the business world becomes more digital, video has become an increasingly important tool for communicating with consumers, security surveillance, and sharing information for analysis. However, as high-definition and ultra-high-definition video becomes more popular, the technology used to provide it must evolve. This is where H.265 comes in.

But what is H.265? H.265 or high-efficiency video coding (HEVC), is a cutting-edge video compression standard designed to deliver higher-quality videos with reduced file size. To remain at the forefront and provide customers with top-notch video content, businesses, and streaming platforms should undoubtedly opt for HEVC.  We will break down all the technical details of H.265 and learn their advantages.

Historical Context of H.265

Before H.265, video codecs such as H.264 and MPEG-2 dominated the scene, but they had limitations in delivering high-quality videos with lower bandwidth requirements. H.265 was developed to overcome these challenges and set new standards in video compression technology.

How H.265 Works

How H265 Works

A H.265 encoder uses sophisticated algorithms to encode video data more efficiently. It divides frames into small blocks, analyzes their content, and compresses them better than previous codecs. This results in higher-resolution videos with reduced file sizes.

H.265 compression follows the same principles as H.264 in that, rather than encoding every pixel from every frame, bandwidth utilization is reduced by identifying static areas (that do not change from frame to frame) so that precise encoding can be given to areas that change.

The difference with H.265 is that the procedure is more aggressive. As part of the compression method, characteristics such as motion correction, spatial prediction, and sample adaptive offset (SAO) image filtering have all been strengthened, in addition to widening the areas inspected for changes or pattern comparison from 16 x 16 pixels to sizes up to 64 × 64.

Advantages of H.265

H.265, also known as High-Efficiency Video Coding (HEVC), offers several significant advantages over its predecessors and other video codecs:

Higher Compression Efficiency

H.265 provides better video compression, resulting in smaller file sizes while maintaining higher quality. This allows for efficient data storage and reduced bandwidth requirements for streaming.

Improved Video Quality

With H.265, videos can be streamed or stored at lower bitrates without compromising visual quality. It supports  sharper and more detailed images in HD or 4K resolutions.

Enhanced Streaming Experience

Due to its efficient compression, H.265 improves the streaming experience by reducing buffering and enabling smoother playback, especially in areas with limited internet bandwidth due to its lower bitrate requirements.

Reduced Data Usage

For mobile users and those on limited data plans, H.265 is a game-changer. It lowers data consumption during video streaming, allowing users to watch more content without exceeding data caps.

Versatility and Compatibility

H.265 is designed to be compatible with various devices and platforms, making it versatile for use across different industries, including video streaming, video conferencing, surveillance, and broadcasting.

Challenges and Limitations

H.265 comes with some challenges and limitations that you should know, such as:

  1. High computational demands for encoding and decoding.
  2. Limited support in older devices may cause compatibility issues.
  3. Decoder processing power makes software decoding more challenging

Despite challenges, H.265 remains crucial, but consider these limitations 

Adoption and Industry Impact

Adoption And Industry Impact

H.265 has gained traction, and its adoption has expanded in various industries, including streaming services, video surveillance, and 4K broadcasting. Its efficiency and improved quality made it a key player in the evolving video landscape.

Thanks to the power of H.265, content creators can now produce high-quality videos while significantly reducing their storage and bandwidth costs. This is especially beneficial for streaming services that handle large volumes of data from multiple sources. 

By enabling the delivery of 4K video with reduced file size, H.265 has revolutionized streaming experiences, paving the way for the next generation of content. 

Z3 Technology has board level solutions that support H.265 to small enclosed encoder systems. Whether you are looking to stream HD or 4K video Z3 has solutions that support HDMI, LVDS and HDMI cameras.
