Nice to meet you. My name is Okuda, PM (Project Manager) of the Development Department.
In this article, I would like to introduce the video delivery system of learningBOX.
Our e-learning system is an LMS that allows anyone to easily create teaching materials and upload video content.
The delivery specifications are based on the "streaming method," which is also commonly used by delivery sites around the world.
There are several methods available for learningBOX, including streaming, so we will introduce them here.

5. Summary
What is the recommended video on demand (VOD) service for e-learning?
VOD stands for "video on demand." It is a service that allows you to watch movies and dramas at a fixed price over the Internet.
This service allows you to watch movies on PCs, smartphones, tablets, game consoles, and various other devices in your home via the Internet or mobile communication lines.
There are various types of VOD services, from those that specialize in movies to those that distribute mostly domestic dramas.
Youtube, for example, is a free video streaming service.
Video distribution on the Internet
Currently, video distribution over the Internet allows users to enjoy movies and dramas through subscription video services such as Netflix and Amazon Prime Video.
There are also many other types of video distribution services that allow users to participate and post their own videos, such as YouTube and Tik Tok, live streaming services such as Instalive, and webinars (webinars), which have a variety of audience sizes.
The devices on which videos can be viewed also vary widely, with most of them supporting viewing on PCs, tablets, and smartphones as standard.
Characteristics of Streaming Distribution and Download Distribution
There are two major types of on-demand delivery: streaming delivery and download delivery.
*On-demand delivery is a method in which content that has been created in advance and uploaded to a server is viewed at the timing requested by the viewer.
What is Streaming Delivery?
Streaming is a technology for comfortably viewing large files such as videos through communication lines. Since large data on the server is loaded little by little and played back sequentially, the viewer can watch without worrying about the time required for downloading or the HD capacity of the device.
What is download distribution?
Downloading is a method in which all data is downloaded to the terminal before playback begins. Before the spread of streaming, downloading was a common video delivery method.
In this method, the video or other data is downloaded from the distributor to the user's terminal and then played back.
Transition from downloading to streaming
Just as the U.S. music market shifted from downloading to streaming around 2015, streaming has become the mainstream trend in video distribution.
In the past, video data was downloaded completely to the device side, and the video file was played separately.
In the past, video data was downloaded completely to the terminal side, and video files were played back separately. In addition, some systems limit the playback player or use a system linked to DRM (Digital Rights Management) to playback the data.
However, with the spread of 4G and 5G lines and broadband, transmission speeds have improved year by year, and with the appearance of new streaming standards, there has been a shift to streaming distribution from the perspective of copyright protection by preventing content redistribution, as well as preventing storage pressure on terminals.
Of course, downloading has not disappeared, and there are still services that offer downloadable distribution.
In particular, in response to the needs for offline viewing, such as "I want to watch on my tablet or smartphone even when I am out of the house and cannot connect to the Internet," some subscription-based distribution services from various companies have prepared dedicated applications that allow downloading in a way that takes content protection into consideration.
Streaming technology used by learningBOX
Here we introduce the delivery method used by learningBOX.
In learningBOX, there are two versions of the Movie Player, version 1 and version 2, with different delivery formats.
Version 1 uses the "progressive download method" and version 2 uses the "HLS streaming method.
Let's take a look at the features of each.
Progressive Download Method
Progressive download, also called "pseudo-streaming," is a method in which content is actually temporarily stored in the cache of a PC or smartphone for playback. Even in poor communication environments, once the data is imported, it can be played back smoothly.
On the other hand, since the content remains temporarily on the device, there are concerns about copyright protection and hard disk space consumption.
HLS Streaming Method
Unlike the progressive download method described above, the "streaming method" only transfers the video being played to the user and does not leave data on the terminal.
Basically, as long as the Internet environment has sufficient transmission speed, smooth playback is possible, and the hard disk is not overwhelmed even during long playback times.
The HLS (=HTTP Live Streaming) format is a streaming transmission protocol developed by Apple Inc.
It is the most widely used streaming standard today.
You can check which version of learningBOX is currently specified in the "Learning Preferences" and you can change the version.
Please use it according to your environment.
Premium plans are recommended for viewing videos in high quality!
The quality of video playback varies depending on the learningBOX plan you use.
The higher the plan you subscribe to, the higher quality videos you can upload.
No matter how high the quality of the video data you have at hand, the quality may appear inferior if the plan you have subscribed to does not apply to your plan.
When using video materials, choose a plan that fits your environment so that learners can learn without stress.
