Latest Patents
One of Arto Hamara's latest patents is titled "Methods and apparatus for signaling offsets and changes in digital broadcast networks." This patent describes systems and methods that enable receivers of digital broadband broadcast signals to determine the time of delivery and the version of a particular signaling table. The receiver can assess whether an update of the signaling table is necessary based on various factors, including specific changes applicable to mobile terminals in a DVB-H network. Additionally, the receiver has the capability to power down while waiting for the signaling table delivery, optimizing its energy usage.
Another significant patent is "Method, system and network entity for indicating hierarchical mode for transport streams carried in broadband transmission." This invention outlines a method for signaling a hierarchical priority mapping of a transport stream to a receiver. It allows for the separation of tuning information between different transport streams with varying priorities. In a wireless hierarchical broadband transmission, one signal can carry both low priority and high priority streams, each identified by its respective transport_stream_id. A priority flag is incorporated into the broadband transmission descriptor to indicate the hierarchy of the transport stream.
