A short introduction into the digital video broadcasting should definitely help some of your to be more familier with what we are talking about when DMB, DVB-H or MediaFlo are mentioned.
The common between all the Digital Broadcasting technologies is that uses transmitters (towers or satellites) to send data to all the recipients that are in range. In a regular Wireless phone network, the transmitters and receivers have dedicated connection between them. In order for a Digital broadcasting to work, the mobile device which will receive the broadcasting needs to be equipped with the appropriate hardware and software.
DMB or Digital Media Broadcasting is a way of digitally transmitting data, TV or radio to mobile devices. The standard is based on Eureka-147 DAB standard but has added error-correction. The DMB systems are two types DMB-T (terrestrial) or DMB-S (satellite). DMB is currently tested in Europe and is actually been implemented and working in South Korea (DMB-S was launched in May, while DMB-T broadcasting started in December).
DVB-H (Digital Video Broadcasting HandHeld) is a competing to the DMB standard and is based on DVB-T (standard for broadcasting digital TV to non-hand held devices). Trials of DVB-H are also underway in many countries. In the US, Modeo, a subsidiary of Crown Castle is expected to launch their DVB-H network in selected cities in 2006. Nationwide deployment to the top 30 US markets is expected in 2007. Modeo's video services will broadcast in QVGA resolution (320x240 pixels) at up to 30 frames per second.
MediaFlo a standard developed by Qualcomm and will be the backbone for Verizon Wireless multicasting network. The service, which is expected to be launched some time next year, will be accessible for Verizon's subscribers through MediaFLO-enabled EV-DO handsets. The service is planned to be initially launched in approximately half of the EV-DO markets, covered by Verizon Wireless and then slowly to expand in order to cover all EV-DO areas.
Qualcomm's MediaFLO will aggregate and distribute the content that is available to all MediaFLO partners(like Verizon) and will provide seamless integration of this content with unique content that individual operators provide to maintain their competitive differentiation. The network will support 50-100 national and local content channels, including up to 15 live streaming channels and numerous clip-cast and audio channels. This content will be delivered in QVGA resolution at up to 30 frames per second.
