Home There are various flavours of Mobile TV, some using 3G (W-CDMA) & CDMAEvDO networks for video streaming and some using dedicated infrastructure using 'radio' frequencies. The main standards are DVB-H, TPtv, MediaFLO and HSPA(3G) DVB-H
The DVB-H specification was developed in June 2004 for accessing DVB services on handheld devices. Broadcasters initially supported the Quarter VGA (QVGA, 320 x 240 pixels) standard, while cellular phone carriers supported Quarter Common Intermediate Format (QCIF, 176 x 144 pixels) in 2002. DVB-H solves the rift between them. When the user watches a program on a mobile
phone, there will be two types of content on the mobile phone screen -- a
broadcast program (such as a drama) by a broadcast service provider, and
custom data relevant to the program (such as online shopping information as
to the shoes an actor in the drama is wearing) prepared by a telecom
carrier. Digital Audio Broadcasting (DAB) TPtv TDtv operates in the universal unpaired 3G spectrum bands
that are available across Europe and Asia at 1900MHz and 2010MHz. It allows
UMTS operators like Orange to fully utilise their existing spectrum and base
stations to offer subscribers attractive mobile TV and multimedia packages
without impacting other voice and data 3G services. W-CDMA MediaFLO It supports up to 20 streaming channels of QVGA (320x240 pixels) quality video at up to 30 frames per second, 10 stereo audio channels (HE AAC+ parametric stereo) and up to 800 minutes of stored Clipcast™ content per day (short-format video clips) and has an average channel switching time of 1.5 seconds without buffering or progress bars.
