Information on how to enable the new Blast Codec is covered in the next chapter, How to Configure Blast Extreme. Important : Many of the optimizations available to the other codecs have not yet been developed for the Blast Codec, including the ability to set custom image qualities. Blast Codec support for the encoder switch was added in Horizon 7.11.If testing reveals the Blast Codec is not yet able to fully support an application or use case, simply switch to one of the other three codecs for now. The Blast Codec should be evaluated for use whenever network bandwidth or display protocol CPU utilization is a primary concern.First introduced in Horizon 7.10, the Blast Codec is rapidly evolving but does not yet support all the optimizations and configuration options available to the other codecs.
It is designed to support the majority of customer use cases, including not just typical Windows and Linux apps like Microsoft Office, but also SaaS applications, line-of-business apps like Point of Sale, plus any that require low-motion, high-quality graphics support such as CATIA, Photoshop, and AutoCAD. The future successor to JPG/PNG, the Blast Codec provides a high-quality user experience while using significantly less CPU and network bandwidth required by other codecs. The latest innovation for Blast Extreme is the Blast Codec. Information on how to enable build-to-lossless mode is covered in the next chapter, How to Configure Blast Extreme. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. In this mode, the codec is able to support applications that require the display protocol to be lossless, ensuring nothing is lost in transmission. JPG/PNG can also be configured to use build-to-lossless mode. It is especially good at reproducing intricate fonts and other screen content with fine details, including still images and low-motion 3D modeling used by design and engineering applications. Used together, the JPG/PNG codec is ideally suited for typical Windows and Linux applications, including Microsoft Office. This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. Therefore, images compressed using JPG cannot be decoded and restored to the same quality they had before compression. While the JPG algorithm attempts to remove only redundant data, in practice other data is lost as well. This means that some of the original image data is discarded (lost) as part of the compression process. These formats employ compression to reduce the size of the content before it is transferred across the network.
JPG/PNGĪs its name implies, the JPG/PNG codec leverages two image formats, JPG and PNG, to encode and decode display content. Blast Extreme now supports four codecs: JPG/PNG, H.264, High Efficiency Video Coding (HEVC), and the new Blast Codec. The second key configurable component is the codec used to encode and decode the screen content transferred by Blast Extreme. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead.
