What is times now live streaming?
Times now live Streaming refers to the way data is transmitted when someone views video online. It allows you to send a small amount of a video file at a time, often from remote storage locations. Client devices don’t need to download the whole video file before they can start playing it. Instead, they can send a small portion of the file over the internet.
Live streaming refers to the transmission of live video over the Internet in real-time, without it being first recorded and stored. Live streaming is possible for TV broadcasts, game streams and social media videos.
The difference between live streaming and regular streaming can be compared to an actor performing a monologue or improvising a speech. The first type of streaming is where the content is stored beforehand and then sent to the audience. The audience is able to receive the content at the exact moment the actor creates it, just as in live streaming.
Live streaming is a broadcast of live streams. These live streams are one-to-many connections that reach multiple users simultaneously. Skype, FaceTime, and Google Hangouts Meet use real-time communication protocols (RTC) instead of the protocols used in one-to-many stream broadcasts.
Raw video data is the visual information captured by a camcorder and used to start live streaming. This visual information is stored in the computing device that the camera is attached to. It is then represented as digital data, or 1s and zeros at the most basic level.

Next, the segmented data is compressed. By removing redundant visual information, the data is compressed. If the first frame shows a person speaking against a grey background and the subsequent frames have the same background, the grey background doesn’t need to render.
Video compression can be thought of as adding new furniture to your living room. You don’t have to purchase new furniture every time you add a chair or side table. It is possible to keep your room’s layout the same, but change one piece at a while, sometimes making more drastic changes as needed. It is not necessary to render every frame in a video stream. Only the movements of people’s mouths or their faces are needed.
Encoding refers to the process by which data is converted into a new format. The encoded video stream is converted into a digital format that can be read by a variety of devices. Common video encoding standards include:
Segmentation fo times now
Video contains a lot digital information. It takes longer to download a file than to download an image or a PDF. It is not practical to transmit all video data over the Internet at the same time, so streaming video is broken down into shorter segments that last a few seconds.
Distribution and caching of Live news (Times now)
After the live stream is compressed, encoded and segmented (which takes only a few seconds), it must be made available for the millions or even billions of viewers who are interested in it. A CDN is required to distribute the stream in order to preserve high quality and minimize latency, while simultaneously serving multiple viewers from different locations.
A CDN is a network of servers that caches and serves content for an origin server. A CDN provides faster performance because user requests don’t have to travel all that far to the origin server. Instead, they can be handled by a nearby CDN. This reduces the workload of the origin server by handling requests and delivering content this way. CDNs allow users to access content from all corners of the globe, as their servers are not concentrated in one area.
The CDN can also temporarily save each segment of the live streaming stream. This means that most viewers will receive the stream from the CDN cache and not from the origin server. The live stream is now closer to the real-time, even though it has a shorter round trip time (RTT), to and from origin server.
Video playback and decoding
The CDN broadcasts the live stream to all users who are viewing it. Every user’s device receives and decodes the segmented data. A media player, which can be either an app or a browser-based video player, interprets the data into visual information and plays the video.
Let’s say Alice creates a live stream using her smartphone. Bob, who lives across the country, joins the stream via his smartphone. Alice begins the live stream by turning her smartphone camera on herself, and then saying “Hello, World!” What is the best way to get that “Hello world” section of the video to Bob on the other side?
First, Alice’s phone will compress and encode that small segment of video. Alice may be filming in her kitchen and recording the first frame. Then, the next frames will record the remaining footage.
The app Alice uses will now send the compressed encoded version of Alice’s “Hello, World” to the CDN. Bob is fortunate that one of the CDN servers are only a few miles from his home so his request for the first segment is almost immediately answered. Depending on where they are located, other live stream viewers might experience less or more latency than Bob.
Bob’s phone decodes each video segment and reconstructs compressed data to show Alice’s kitchen wall in every frame. Finally, just a few seconds later, Alice’s face is displayed on Bob’s smartphone. Bob hears and sees her greeting.
What is the importance of a CDN for times now live streaming?
Bandwidth is the limit of data that can pass through a point on a network at any given time. This measurement is called “bandwidth”. A choke point is a place where data flow is slowed or stopped at excessive levels. A choke point is similar in nature to traffic slowdowns that can occur when too many cars try to use one-lane roads.
The stream will slow down if all viewers are receiving stream data from the source server. The choke point can be eliminated if stream delivery is shifted to a CDN.
Global content delivery: CDNs can deliver content to any global audience because they are available all over the globe. A New York origin server cannot serve content to a Milan audience. This is especially true for heavy content such as video. A CDN, however, can forward and serve content from any point in its network. This means that someone in Milan who is watching a stream live from New York can access the stream from Milan, rather than waiting for it from New York.
RTT and latency reduction: Using a CDN to deliver content worldwide reduces latency. This is because RTT (round trip time) is reduced. As a result, the request-response round trip for live streams is significantly shorter in both distance and time. The stream data and stream request no longer have to travel the same distance as the source. This helps to keep the stream “live” and reduces delays.
Workload: A server’s ability to respond to user requests for data requires some computing power. One server can be overwhelmed by responding to too many requests for video data. CDNs can use dozens to hundreds of servers, which can reduce the load on the origin server and keep it running.
