Video streaming over the internet is a task since video files are quite heavy in size. But how does the streaming happen if files are heavy? It is with the help of streaming technology which includes encoding via an encoder, transcoding with a transcoder, delivery through a content delivery network, management with a content management system, etc. The role of the video codec is quite crucial at first since it makes the file more manageable and therefore streamable. Let us understand what is video codec and how it helps in making the file more manageable and streamable.
What Is A Video Codec?
A video codec helps in compressing the RAW video files. It helps in streaming the content easily. Codec consists of both the encoder and the decoder. An encoder helps in compressing the video files and making them transferrable. On the other hand, a decoder is used for decoding the file and preparing the video for playback. Using a codec, all the unnecessary data is erased or removed, and the file is compressed. Video codec compresses the video file by compressing the frame of the video making a low file size and hence making the delivery easier and faster. Without a codec, it will be difficult to transfer the video file over the internet.
How Does The Video Codec Work?
As we stated above, raw video files are heavy in size. All of us are aware that video files are collections of still images that are used continuously to create movement. These files are often heavy to stream over the internet since it needs bandwidth and storage to deliver the video to the end audience. Video codec helps in compressing the file.
Compression can be divided into two different parts which are inter-frame and intra-frame compression.
In inter-frame compression, all the static parts are used in the consequent frames. For instance, if one person is speaking on a certain topic with a stationary background then there is no need to take all the frames of the stationary background. While on the other hand, in intra-frame compression, every frame is compressed.
Inter-frame compression is considered more efficient than intra-frame compression. Most of the codecs are optimized to get over all the redundant images in the file making the file short and delivery of the file instant.
In a current time of speed and intense competition in the video streaming arena, it becomes inevitable to deliver video content quickly. It brings a good user experience and video codec help in doing the same; quick delivery and better user experience. This, in all, brings more viewers to your platform since they do not have to face any lag while watching their favorite content.
Google Releases Lyra V2: A New Audio Codec
Google has recently released a new codec named Lyra V2, a better, faster, and more versatile speech Codec. The architecture of the new Lyra V2 brings scalable bitrate capabilities, provides better performance, provides wider platform support and generates a higher audio quality. With the release of Lyra V2, Google is trying to evolve with the community.
The Architecture Of Lyra V2
The latest release of the Lyra V2 is based on SoundStream, an end-to-end neutral audio codec. The architecture of the latest audio codec includes a residual vector quantizer Or RVQ which is present before and after the channel of transmission. RVQ quantizes the encoded content into a bit stream and thereafter reconstructs it at the decoder side.
This integration of RVQ into the codec infrastructure allows changing the bitrate of Lyra V2 at any time just by selecting the number of quantizers to use. To generate higher-quality audio more quantizers are used. This codec uses three different bitrates which include 3.2 kbps, 6 kbps, and 9.2 kbps which enables the developers to choose bitrates suitable for network conditions and other requirements. With this new architecture, the delay in the audio delivery is reduced from 100 ms from the previous version. It is most comparable to the most used codec Opus which has an approximate delay of 26.5 ms, 46.5 ms, and 66.5 ms.
This latest audio codec released by Google has the ability to encode and decode audio by 5x than the previous version. Apart from the speed and performance, the quality of the audio generated by this new audio codec has also improved. This model of V2 is exported in TensorFlow Lite. All this makes V2 a great alternative to other state-of-the-art audio codecs. It has the ability to be connected with more devices in bandwidth-constrained environments, making it an appropriate choice for higher audio quality requirements.
UniqCast IPTV/OTT/DVB Platform is now available in the Cloud
UniqCast, the market leader in providing end-to-end IPTV/OTT/DVB solutions has announced its availability on Cloud.

With this step, UniqCast is trying to make the deployment of new services or replacement of the existing ones quickly with the least investment and no risk. The availability to launch multi-screen applications in a day with a robust backend and anti-churn quality will be helpful for video streaming services to decrease churn and increase subscribers instantly, says Darko Robič, CEO at UniqCast.
Apple iPhone 14 launch event: Place, Time and Expectations
The wait for the latest Apple iPhone 14 is almost over. The Apple ‘Far Out’ event is going to be held tomorrow (September 7). The main highlight of the event will be the Apple iPhone 14 but it will probably not end there. Apple is expected to introduce a range of products in its upcoming event which includes the next-generation Apple Watch- Series 8, 8 Pro, and Apple Watch SE 2.
About the event
Apple is going to launch a series of products where the main focus and highlight will be the Apple iPhone 14 series. The event will be held tomorrow at 10:00 AM PT (10.30 pm IST). The event will be held at Apple Park, Cupertino. It will be the first in-person event after the pandemic. The ‘Far Out’ event will be live streamed on selected platforms which include Apple’s official website, companies official YouTube channel, and the Apple TV app. As an option available on the company’s website, users can add the event to their calendars as well. To proceed further, you can visit the official website: https://www.apple.com/
What to expect
The event is going to be highlighted with the Apple iPhone 14 series but that is not the end of the event. The company may launch a series of products including four variants of the iPhone 14 (most likely) which include the iPhone 14, iPhone 14 Plus, iPhone 14 Pro, and iPhone 14 Pro Max. This time, Apple is going to skip the mini variant as launched in iPhone 12 and 13.
