Understanding H.265 Bonding

The shift in the transmission of video files wirelessly from analog to digital means video file transmissions have vastly improved, and the load capacity of bandwidth have greatly expanded. This is due to the fact that digital signals can be compressed nowadays, and thus, video digital signals can now be transmitted digitally. This compressing of digital files allows for better transmission because the capacity of bandwidth is now greatly expanded because of compression.

As video technology evolves and advances, it may engender some incremental problems. For example, the raw imagery from HD (High Definition) video camera is enormous and can only be transmitted conveniently by compressing the video file. By compressing the video files, the amount of data is reduced to a manageable level. Compression can be done either by reducing the video quality (which can result into a noisy or soft video imagery) or by using a “better” compression technique. This compression technique is similar to packing one hundred apples in a carton (each 80 pieces) without reducing the apples into a pulp. By arranging the apples inside the carton intelligently, it is possible to find ways to fit the apples while preserving the fruitiness of the apples.

How Does H.265 Work?

The introduction of HD or High Definition, 4K and the much later 8K or ultra-high definition video format had greatly improved the video imagery but also reduced the transfer rate than any other new ways of compression. One of the latest emerging technology that uses “better” compression technique is the HEVC or High-Efficiency Video Coding, otherwise known as H.265.

The H.265 video compression standard is widely believed as the successor to the present mainstream MPEG-4 AVC (Advanced Video Coding) or H.264 but offers about twice data compression ratio than its predecessor. The H.264 or MPEG-4 AVC is better known as the compression scheme of Blu-ray Disc.

The H.265 or HEVC is considered by many as an extension of the H.264, because the former shares the working principle of the latter. Both compression standard works by means of the so-called “motion compensated prediction” wherein each part of the video frame is compared to one another to search for redundant parts within the same frame (intra-prediction), and on other succeeding frames (inter-prediction). While the H.264 works up to 16×16 pixels, the H.265 can describe up to 64×64 pixels. Moreover, the H.265 hardware encoder provides better motion vectors as well as motion compensation filtration. However, despite the H.265 requirement for greater processing capability for video compression, the effects on the amount of computation required to decompress the video is negligible.

At present, the H.265 is slowly supplanting the older H.264 as the main video compression standard. Many well-known electronics manufacturers are switching to H.265 standards and many still are announcing the intention of providing support. Likewise, a number of broadcasting and film production companies are now using H.265 video formats. H265 Streaming device is likewise, gaining popularity in video streaming field because of better video transmissions.

The H.265 video compression format is still evolving and is being further developed. At present, there are at least four versions of H.265 and each of the succeeding version is a development of the preceding version. It can be expected that in the near future, further versions of H.265 may emerge along the way.
