Nowadays, live  streaming has gradually become an important way for people to entertain  themselves in their daily lives. Whether we are watching streaming videos  online or watching live broadcasts, this requires the help of video streaming  protocols. Different devices are suited to different video streaming protocols;  for example, Apple devices are more suited to the HLS video streaming protocol.  Understanding the most popular HLS and DASH video streaming protocols can help  you choose the right one for your device. Furthermore, this can help you reduce  latency when watching videos online. So, what is HLS? What is DASH? What are  their characteristics and differences? Don't worry, this tutorial will tell you  all the answers.<\/p>\n<h2 id=\"part1\" class=\"title2\">Overview of Each Protocol<\/h2>\n<p>What does HLS mean? HLS is the abbreviation  of HTTP Live Streaming, which refers to the HTTP real-time streaming protocol.  HLS is an HTTP-based streaming media network transmission protocol developed by  Apple. It is mainly used to implement real-time or on-demand audio and video  streaming playback on the Internet. HLS can encode audio and video content and  split it into a series of short TS format media segments. It then generates an  M3U8 index file containing the URLs of these segments. When playing these  TS-formatted media segments, we can follow the instructions in this M3U8 index  file to play them sequentially. This allows for a better video viewing  experience with less demanding network conditions.<\/p>\n<p>DASH actually refers to Dynamic Adaptive  Streaming over HTTP. It's an adaptive streaming protocol developed by MPEG, the  international standards organization. Similar to HLS, DASH can encode audio and  video content and split it into multiple media segments with different bit  rates and resolutions. DASH then generates an MPD manifest file describing  these segments. This MPD file can be retrieved via HTTP. Based on current  network conditions and device capabilities, the most appropriate media segment  can be dynamically selected and downloaded for playback, achieving a smooth,  adaptive streaming experience.<\/p>\n<div class=\"tc2\"><a href=\"https:\/\/www.leawo.org\/entips\/wp-content\/uploads\/2025\/09\/what-is-hls-Overview.jpg\" class=\"highslide\" rel=\"highslide\"><img decoding=\"async\" data-src=\"https:\/\/www.leawo.org\/entips\/wp-content\/uploads\/2025\/09\/what-is-hls-Overview.jpg\" alt=\"what-is-hls-Overview\" width=\"650\" height=\"\" class=\"alignnone size-full wp-image-136102 lazyload\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 2000px; --smush-placeholder-aspect-ratio: 2000\/1111;\" \/><\/a><\/div>\n<h2 id=\"part2\" class=\"title2\">Key Differences Between HLS and DASH<\/h2>\n<p>Below, I will use a table to show the key  differences between HLS and DASH.<\/p>\n<div class=\"wp-table\">\n<table border=\"0\" cellspacing=\"0\" cellpadding=\"0\" width=\"100%\">\n<tr class=\"wp-jk\">\n<td width=\"184\">\n      Features <\/td>\n<td width=\"184\">\n<p align=\"center\">HLS<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">DASH<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"184\">\n<p align=\"center\">Created    by<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Apple    Inc.\u00a0\u00a0\u00a0\u00a0\u00a0 <\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">A    consortium of companies led by MPEG<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"184\">\n<p align=\"center\">Compatibility<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Strong    on Apple devices, widely compatible with Android<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Excellent    on Android, Windows, and other platforms<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"184\">\n<p align=\"center\">Transport    protocol<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">HTTP<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">HTTP<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"184\">\n<p align=\"center\">Video    codecs supported<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">H.264,    H.265<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Any    codec, commonly H.264, H.265<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"184\">\n<p align=\"center\">Audio    codecs supported<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">AAC,    AC-3, E-AC-3<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Encoding-agnostic<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"184\">\n<p align=\"center\">Encryption<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">AES-128,    FairPlay<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">AES-128,    Widevine, PlayReady, FairPlay, ClearKey<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"184\">\n<p align=\"center\">Latency<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Typically,    higher (6-30 seconds)<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Lower    latency achievable (2-10 seconds)<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"184\">\n<p align=\"center\">Segmentation<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Traditionally    uses MPEG-TS, newer versions support fMP4<\/p>\n<\/td>\n<td width=\"184\">\n<p align=\"center\">Primarily    uses fMP4, offering better efficiency and compatibility<\/p>\n<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<h2 id=\"part3\" class=\"title2\">Industry Adoption and Use Cases<\/h2>\n<p>You can learn about the industry adoption  and use cases of HLS and DASH through the following points<\/p>\n<h3 class=\"title6\">1. Device Compatibility<\/h3>\n<p>Currently, iOS and macOS devices support  HLS by default. Therefore, Apple devices can achieve optimal performance with  the HLS protocol. Of course, most Android devices also support the HLS  protocol.<\/p>\n<p>DASH demonstrates good compatibility with a  wide range of devices, including Android, Windows, and smart TVs. Therefore,  DASH is a popular choice for many devices.<\/p>\n<h3 class=\"title6\">2. On-Demand and Live Streaming<\/h3>\n<p>With support from Apple devices, the HLS  protocol efficiently delivers on-demand video to users. Therefore, HLS is  suitable for delivering on-demand content such as movies and TV shows. However,  HLS can incur higher latency when delivering live content.<\/p>\n<p>DASH is suitable for low-latency scenarios.  Furthermore, DASH has low network requirements. Even in poor network  conditions, DASH can still efficiently transmit data. Therefore, DASH is  suitable for delivering live content such as sports events and live news  broadcasts.<\/p>\n<h3 class=\"title6\">3. Content Protection and DRM<\/h3>\n<p>HLS can generate M3U8 links to index source  videos. Therefore, we can easily download unprotected M3U8 videos and <a href=\"https:\/\/www.leawo.org\/entips\/how-to-convert-m3u8-videos-to-mp4-1429.html?utm_source=leawo.org&utm_medium=250918_convert_m3u8_video_to_mp4&utm_campaign=1428\"title=\"convert  M3U8 videos to MP4\" target=\"_blank\">convert  M3U8 videos to MP4<\/a>. Furthermore, HLS supports Apple's FairPlay DRM,  effectively protecting videos.<\/p>\n<p>DASH generates MPD files to index the  source files. DASH primarily uses CENC to provide DRM protection for the source  videos.

Cost<\/h3>\n<p>Because HLS primarily transmits content for  Apple devices, HLS incurs lower operational costs. However, DASH has a wider  range of applications and uses a wider variety of encoders. Therefore, DASH  incurs higher operational costs. Future considerations are needed to reduce the  cost of using DASH.<\/p>\n<h3 class=\"title6\">2. DRM Protection<\/h3>\n<p>HLS primarily uses Apple's FairPlay DRM  protection technology. While HLS effectively protects video content, its scope  of application is relatively narrow and not widely adopted.<\/p>\n<p>DASH can protect video content using  various DRM technologies. However, this requires DASH to integrate these DRM  technologies, which is technically demanding and difficult to implement.<\/p>\n<h3 class=\"title6\">3. Implementation Requirements<\/h3>\n<p>HLS is primarily implemented on Apple  devices. Therefore, HLS has a large developer community, making implementation  easier.<\/p>\n<p>DASH is compatible with a wide range of  encoders and devices, offering greater flexibility. However, this also makes  implementation more complex.<\/p>\n<div class=\"tc2\"><a href=\"https:\/\/www.leawo.org\/entips\/wp-content\/uploads\/2025\/09\/what-is-hls-Challenges-and-Limitations.jpg\" class=\"highslide\" rel=\"highslide\"><img decoding=\"async\" data-src=\"https:\/\/www.leawo.org\/entips\/wp-content\/uploads\/2025\/09\/what-is-hls-Challenges-and-Limitations.jpg\" alt=\"Challenges-and-Limitations\" width=\"650\" height=\"\" class=\"alignnone size-full wp-image-136102 lazyload\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 686px; --smush-placeholder-aspect-ratio: 686\/323;\" \/><\/a><\/div>\n<h2 id=\"part6\" class=\"title2\">Tip: How to Download MPEG-DASH and HLS Streams<\/h2>\n<p>It's important to note that most video  streaming services currently use the HLS or DASH protocols.
