E-Songbook is a device such as a phone or a tablet that connects to a karaoke player to select, reserve, and play the songs. Until now, the E-Songbook required an app to connect to a karaoke player. And since the app was hardware specific, a different E-Songbook or a different phone or tablet required a different app. This complexity discouraged customers from using them.

Requiring an app was also prone to connection failure, delays, and incompatibility. The connection failure came from non-standard app designs. The delays came from ever increasing song contents. The incompatibility came from exploding number of new phones and tablets each carrying different specs.

The built-in web server of the PlayCDG Online solves the problems of requiring an app by allowing all E-Songbook, phone or tablet to connect using a browser. For example, customers with iPhone or iPad can connect using the browser Apple Safari. Customers with Android phones or tablets can connect using the Google Chrome. The connection is made based on the TCP/IP worldwide network protocol, and it is fast, efficient, and the best of all, supports all E-Songbooks, phones, and tablets.

When connected, the Customer Interface that appears on the E-Songbook, phone or tablet is as follows.

Customer Interface

It has the controls to search, reserve, play the songs, and to change the pitch, tempo, and voice cancel. These controls are selectable in the option settings.

With the ease of connecting, there comes also the savings. The hosts no longer need to prepare the E-Songbooks customized with apps. The customers can now use their phones or tablets with ease. The savings will continue as the hosts also do not need to replace the E-Songbooks that are dropped or drowned.

Through the option setting, PlayCDG Online also provides multiple control levels for the customers and hosts to connect to the player.

  • The lowest level allows users to browse the song list but without the ability to reserve or play the songs.
  • The highest level grants full control, typically ssigned to the hosts.
These different levels can connect to the player simultanesouly, enabling the customers and hosts to login at their respective control levels.


A karaoke player typically plays the audio and video through the HDMI, VGA, or RCA outputs of the player. The video is sent to a stage TV and the audio is routed to the stage speakers.

PlayCDG Online, with a built-in web server, can stream the audio and video outputs simultaneously as it plays. This means it can stream the music and lyrics to the phones and tablets connected in the network server. These devices will then play the music and lyrics using their own speakers and displays effectively becoming mini satellite karaoke players.

With streaming, the customers have the advantage of not being tied to the stage TV or the speakers. They can move around, carrying the lyrics and music with them, and enjoy karaoke anywhere – whether it’s out on a balcony, by the pool, on deck, etc.
