This is where broadcasters and mobile (cell) telcos come together to provide consumers with access to video content on their mobile phones and tablet computers. This includes downloads to flash memory, 3G and 4G streaming and mobile on-demand broadcast TV. The landscape is complex as there are many competing formats including DVB-H, DVB-SH, MediaFLO, ISDB-T, S-DMB/T-DMB in different regions and backed by different hardware manufacturers, technology suppliers, content providers and mobile operators. Also there are any number of screen resolutions and aspect ratios to be catered for. China is adding its homegrown China Multimedia Mobile Broadcasting (CMMB). In Europe, the European Union has decided to support the DVB-H standard for mobile TV. DVB-H uses a separate broadcast network, rather than a phone network, to send TV content to phones or mobile devices.
