Qterics (formerly Broadcast Data Corporation and later UpdateLogic Incorporated ) is a company which has developed a system for datacasting firmware upgrades to digital television devices.
TV manufacturers work with UpdateLogic to schedule the network distribution of the software patch(es) and optimize the roll-out to ensure the TVs receive it.
The upgrades are transmitted repeatedly every day over a period of many months, in part so that the update is not missed due to a power outage, being unplugged (such as to prevent lightning damage while a resident is away, or perhaps being in storage), or due to data corruption or data loss caused by interference or weak signal strength in rural areas or mountainous terrain - which only occurs in the terrestrial broadcast distribution.
Software updates for television sets have fixed issues with video resolution, format compatibility, channel changing speed, V-chip ratings, user interface, timer controls, and more.
Devices such as Blu-ray players, mobile/handheld TVs, set-top boxes and gaming consoles are capable of using the service - since they are connected to the Internet, a cable network, and/or a digital TV antenna.
