Mobile Media Delivery & Patents

Nellymoser Awarded Multiple Patents

In its early history, Nellymoser developed technology that allows users to hum a melody into their mobile phone, convert the resulting audio into a series of discrete tones, and format and deliver the sequence to their device in the form of a ring or ringback tone. There were a number of technical challenges to overcome in order to make this possible.

Even the best singers do not produce sounds with pitches that match notes of the chromatic scale (the chromatic pitch determination problem) and often the boundaries between notes are blurred by co-articulated sounds (the note segmentation problem). In addition to these problems, it was necessary to create an intuitive and responsive interface that made it easy for users to get the results they desired with a minimal amount of effort (the mobile interface problem), and to deliver the ringtone to a variety of devices each with their own specific format (the mobile ecosystem fragmentation problem).

Nellymoser has been awarded three patents related to the technology to make this possible, and the company has been continuing to solve similar technology problems related to mobile content, mobile user interface, and mobile media delivery.

Nellymoser's strengths in mobile media delivery

The Nellymoser Platform has three different methods of delivering video and audio to mobile phones: RTSP-based and HTTP-based video and audio streaming, and HTTP-based video and audio downloads. Each of these solutions addresses a specific class of mobile phones and cellular network types.

Nellymoser's device database specifies the available and optimum video and audio formats and methods of media delivery for every mobile phone given the phone model and network type. The device database contains a wealth of expertise and knowledge gained through extensive testing of video and audio playback on the enormous number of supported handsets available to users.

For popular handsets, video and audio encoding is optimized for the network and for the handset's decoder, player, and speaker (or headset) in order to provide the best possible user experience. Tradeoffs between different media delivery methods involve a complex, multi-dimensional optimization of playback quality, bandwidth (which is related to cost of delivery), security, memory requirements, and processing speed requirements. Nellymoser has an additional five pending patents that pertain to performance-based techniques for optimizing interactive media systems and the associated client applications and client-server communication, and for optimizing content for delivery to mobile devices.

Nellymoser's expertise and knowledge of mobile services creation and media transcoding enable the company to keep ahead of and quickly adapt to the changing and extremely fragmented landscape of mobile devices, media formats, and networks.
