The word “Streaming” is self-descriptive. Streaming is method of viewing video or listening to music or audio content real time without downloading. A continuous transmission of audio or video files from server to client happens in Streaming. When the media files are played the on the client device are stored remotely and are transmitted in seconds time over the internet. Unlike the downloaded files users can Pause, fast forward and rewind in streaming unless it is live.

Difference between Streaming & Downloading

1Streaming:

  • Media files are accessed from server, provider or another device
  • Data is continuously used while streaming any media file. Hence more data is used.
  • No external space is required to store the files and the media is played continuously.
  • Typically content buffers for few seconds depending on the speed of the internet though buffering doesn’t happen all the time

2Downloading:

  • Media files are downloaded to another device, hard disk etc
  • Data is used once while downloading. Once downloaded the media file plays without using any data. Media can be played any number of times.
  • No buffering is involved but you will require to wait till the download is complete
  • Media can be transferred from one device to another depending on the copyright of the content.

How streaming works?

Media is broken into data packets in streaming. As the streaming starts, server starts sending the packets. The audio or the video player in the browser on the client device takes the flow of the packets and the audio or the video streams. For example, your computer or phone receives the beginning of the movie, you will start to watch the movie. As the movie continues the rest of the data get transmitted.

We have heard of many live streaming companies, for all these companies to stream the content they require server or cloud platforms to store the content. Big companies have their own content delivery network (CDN), a global network of storage servers store the cache content so it is quickly accessible. Having CDN will reduce the latency and bandwidth costs. Third party live streaming solution providers are available in the market to store the cache content of the companies.

The continuous flow of the media depends on the reliability of the internet with sufficient speed so that there is no buffer of the video that is played for the users. Minimum speed should be at least 2Mbps/sec for a good streaming experience without any buffer or low quality. When the connection is slow we see too many pauses, while the buffering happens on the device. Users have been casting and streaming online videos to their TV screens now a days.

There are different ways to stream videos

Streaming: The videos which are already shot and produced are uploaded to a video hosting platform.

VOD: Referred as Video On Demand. The users chooses what content they want to watch on demand. 3 types of VOD platforms are AVOD (Ad), SVOD (Subscription) and TVOD (Transactional).

Live Streaming: The videos are recorded and broadcasted in real time.

The files are sent in a compressed form and while viewing these are viewed in high quality (decompressed) form on your device.

Actual files are never received in live streaming as data is temporarily stored and displays the small amount of data on your device and then discards them as you continue to watch. Most of us use Instagram, Twitter and Facebook on your mobile devices these social media have the live streaming elements as Facebook Live, Twitter live and Instagram Live.
