  • Patent number: 8719859
    Abstract: A channel remapping pre-notification (RPN) message is transmitted in each of multiple frequencies prior to movement of data associated with one or more virtual channels to one or more different frequencies. The RPN message is also sent prior to transmission of a Virtual Channel Table (VCT) reflecting channel movement. If a receiving device is unable to find data associated with a selected channel subsequent to the channel movement, the stored RPN information can be used to identify a new frequency for that selected channel.

  • Patent number: 8677421
    Abstract: An object of the present invention is to provide a digital broadcast reception apparatus that allows a stable viewing even if a reception environment changes along with a movement. In the present invention, based on current position information indicating a current position detected by a current position detection section and broadcast area information stored in a broadcast area information storage section, a search-mode switching control section instructs a tuning control section to select a diversity operation mode if the current position is close to a boundary of a broadcast area, and select an independent reception operation mode if the current position is not close to the boundary of the broadcast area. In the diversity operation mode, a first system and a second system are tuned to the same physical channel, and cooperate with each other to demodulate a digital broadcast signal and a make an output through a diversity process.

  • Patent number: 8665380
    Abstract: In accord with embodiments and implementations consistent with the present invention, rather than perform a full scan of every frequency to find a channel, the tuner is programmed to find a reasonable sample of channels. For example, the tuner can search for at least two or three channels to determine the frequency plan of the channels (by virtue of detection of at least one channel) and then use one of the known plans to directly identify the frequency map. The process can then step quickly through each frequency, without optimizing or fine tuning each channel, to determine the existence of a channel. With this process the number of tunable channels is found quicker and the initial setup time is shortened. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
