When it comes to digital outreach and audience impact, video content reigns supreme. Did you know...
- Every day, the average user watches 40 minutes of YouTube video on their device. Every day, 6 billion hours of YouTube video are watched.
Facebook videos are shared twice as much as text or image posts.
Facebook Live videos are watched three times longer than other videos.
Almost every online platform, big or small, is incorporating video chat or other interactivity to increase usage and user engagement. Otherwise, they risk losing relevance with each generation.
Consider one of the digital behemoths: Facebook. At their F8 Conference in 2018, Facebook announced the one-on-one and group video chat feature on Instagram Direct. This feature allows users to connect with each other via real-time video chat even if they are not physically present. There is no doubt that many popular social media platforms are focusing more on the integration of real-time audio and video technology into their platforms.
Omninos is already assisting many businesses in transforming their traditional applications to excel in the video revolution. These developers and businesses rely on Omninos to deliver an unrivalled level of excellence to their app. Here's just one example. Momo, China's most popular social and dating app, began to investigate a new use case for real-time audio and video communication features, which are becoming popular in the market, long before Instagram's announcement: "KTV Together."
KTV stands for Karaoke Television. It allows people to use a microphone to sing along with recorded music. KTV is deeply embedded in Southeast Asian culture. People used to need a karaoke box and a TV to get started. Because nearly everyone now owns a smartphone, online karaoke can be a new venture in the social media market—one that Omninos SDK is eager to assist you in discovering and dominating.
How Does "KTV Together" Function?
The following demonstration video demonstrates the specific workflow and basic features:
- After creating a chat room, the host can enable the KTV feature and grant microphone access.
The room host selects a song from the internet (through a karaoke database, such as Karafun). By following the video and subtitles, the participants and host can begin singing along with the songs.
Other members of the audience can send requests to take over the microphone, allowing them to sing a different song.
Singers can also change the background music and volume.
The current song can be played, paused, or skipped by the room host.
The Difficulties of Online KTV
KTV is very similar to the basic use case of live broadcasting. It does, however, present its own set of difficulties.
Online KTV Song Synchronization
Control emphasises participants singing "together." The chat room host can invite multiple listeners to sing, giving everyone a chance to shine.
The "microphone" access can be transferred to different audiences in sequence during this process. And the host can still control the song that is playing, such as playing or pausing it. However, when we use RTMP to send the data, the network delay is relatively high. When the host pauses or skips a song in good network conditions, it may take 3-4 seconds for the audience's client side to receive. Or the song may have already begun, but the next singer's client side has not yet begun. The delay may exceed 10 seconds if the network is poor.
Excellent sound and image quality
Singers want the best experience possible so that they can demonstrate their vocal abilities. If the platform cannot provide high-quality audio, the user experience will suffer. In this scenario, the image quality of the music video is equivalent to that of one-on-one or group communication. Jitter and blur are also issues in online karaoke apps. If developers want to build the platform entirely on their own, they must use the UDP protocol for transmission and optimise strategies for edge node deployment, network congestion, weak network transmission, and so on.
Simultaneously, good sound and image quality, as well as low latency, are variables at both ends of the spectrum. In addition to optimization strategy, developers must optimise codec algorithms to reduce audio and video delay at the client side as much as possible.
How Should We Approach It?
- The room host activates the "KTV together" feature and takes on the role of lead singer.
The client side of the host pulls and reads data from a third-party Karaoke database.
The audience makes a request for "microphone" access.
After the host approves the request, the audience can choose songs from the Karaoke database.
The host's voice and background music are sent to the cloud via UDP (Omninos's SD-RTN).
The UDP protocol sends audio and background music from the host to the audience.
The singer has access to the "microphone" when it is time for the next singer to sing. With the exception of music control access, the singer should have the same access as the host.
The Benefits of Using Omninos SDK for Your Online Karaoke App:
Experience high-quality audio and video.
In terms of audio frequency, the Omninos SDK offers industry-leading audio and video encoding/decoding technology, including 192kbps 44.1KHz sampling of high-quality audio, such as traditional KTV. To ensure video clarity on the client side, the SDK also supports 720p and 1080p high-definition image transmission.
Reduced Video/Audio Latency and Improved Synchronization
Audio and video data are transmitted through a private UDP protocol with lower latency using Omninos's SD-RTNTM real-time communication network. As a result, Omninos SDK can improve audio and video synchronisation between hosts and audiences. Simultaneously, SD-RTNTM has algorithms that optimise the routing path, avoiding network congestion and the impact of network failure.
SD-RTNTM has nearly 200 data centres worldwide and supports over 200 countries and regions. It has the potential to power a wide range of applications in the global market.
How will you implement Omninos SDK in your Karaoke app? Do you intend to build a new Karaoke function from the ground up, or will it be an add-on to your platform? We want to see your brainstorming genius and how you use Omninos to make your vision a reality.
Voice Control is supported.
In addition to the basic KTV features, Omninos's SDK allows developers to include host controls in their application, such as volume adjustment, song skipping, microphone access switching, and so on.
