![]() ![]() HLS is another streaming protocol in wide use today. This prevents the video from stopping altogether if network bandwidth is suddenly reduced. A video player can switch from one quality level to another one in the middle of the video without interrupting playback. This happens during the encoding and segmentation processes. Several streaming protocols, including MPEG-DASH, HLS, and HDS, allow for adaptive bitrate streaming.Īdaptive bitrate streaming is possible because the origin server encodes video segments at several different quality levels. The video player automatically switches to a lower or higher quality picture in order to adjust to network conditions – for example, if the user currently has very little bandwidth, the video will play at a lower quality level that uses less bandwidth.Īdaptive bitrate streaming is the ability to adjust video quality in the middle of a stream as network conditions change. Decoding and playback: As a user's device receives the streamed data, it decodes the data and plays back the video.In almost all cases, a content delivery network (CDN) helps distribute the stream more efficiently. Delivery: When users start watching the stream, the encoded video segments are pushed out to client devices over the Internet.MPEG-DASH allows the use of any encoding standard. Then the segments are encoded, meaning formatted in a way that multiple devices can interpret. The server also creates an index file – like a table of contents for the video segments. Encoding and segmentation: The origin server divides the video file into smaller segments a few seconds in length.The main steps in the MPEG-DASH streaming process are: This ensures that the stream is rarely blocked by a firewall, which can block streaming protocols that use specialized or unusual ports. With HTTP, the stream goes to a standard port (port 80 or 443) that is almost always open. MPEG-DASH uses HTTP, which is an advantage because most of the Internet already uses HTTP. Web applications use HTTP to send data back and forth in a way that devices at both ends will be able to interpret this is sort of like two people from different parts of the world using a common language to communicate. HTTP is a layer 7 protocol for communicating over the Internet. ![]() This makes it possible to stream videos at different quality levels, and to switch in the middle of a video from one quality level to another one. MPEG-DASH is similar to HLS, another streaming protocol, in that it breaks videos down into smaller chunks and encodes those chunks at different quality levels. DASH stands for "Dynamic Adaptive Streaming over HTTP." Because it is based on HTTP, any origin server can be set up to serve MPEG-DASH streams. Video is streamed over the Internet so that the client device does not have to download the entire video file before playing it. Streaming is a way of delivering data over the Internet so that a device can start displaying the data before it fully loads.
