Abstract

According to the present invention there is provided a datacast distribution system which allows for the distribution of movies, music, games, application software, and the like using a new or existing terrestrial digital video broadcast (DVB-T) network.

Claims

1. A system for the distribution of content over a wireless link using new and existing terrestrial digital video broadcast networks, comprising:

one or more global caster modules, wherein each of the global caster modules receives content to distribute to all locations in a network;

one or more local caster modules, wherein each of the local caster modules receives content to distribute to only certain locations in said network; and

one or more datacast transmission devices associated with at least one of the modules, wherein the network utilizes bandwidth partitioning and allocation to optimize bandwidth by use of the global caster modules and the local caster modules,

wherein the partitioning is based on day-type profiles that are mapped to calendar dates,

wherein blocks are allocated based on bandwidth monitoring periods and deployment period blocks,

wherein a bandwidth monitoring period determines time when free bandwidth is available,

wherein based on the bandwidth available and day-type profiles one or more deployment blocks corresponding to one or more content providers are marked as reserved, and

wherein one or more assigned identifiers corresponding to one or more of the deployment blocks are forwarded to one or more of the content providers.

2. The system of claim 1, further comprising:

one or more broker modules, each broker module receiving content from at least one local caster module and at least one global caster module.

3. The system of claim 2, wherein:

each of said one or more transmission devices is associated with one or more of said broker modules.
