摘要:
A method for operating an image display device, said method comprising a first step of verification during which each transponder in a preloaded transponder list in association with a satellite is successively verified such that a respective transponder's parameters are fed to a demodulator to verify whether signal lock is achievable, if signal lock is achieved, a first step of transponder information retrieval during which presence of network information tables (NIT) at the tuned frequency is checked and if transponder information is retrieved from the network information tables, a first step of transponder list update during which at least one transponder's parameters are compared to existing preloaded transponder parameters and at least one new transponder with new parameters is included in the transponder list in association with the given satellite.

A method of operating a radio in a vehicle includes tuning the radio to a first radio source. Information identifying the first radio source is transmitted from the vehicle to a remote processor. The processor monitors broadcast content of the first radio source on a web site. The processor identifies a second radio source having broadcast content matching the broadcast content of the first radio source. Information identifying the second radio source is transmitted from the processor to the vehicle. When a quality of a broadcast signal from the first radio source received at the vehicle falls below a threshold quality level, tuning of the radio is switched from the first radio source to the second radio source.

A method of generating television Audience Measurement System (AMS) reports and a system executing the method are disclosed. The method comprises the steps of receiving a plurality of encoded report payloads from a plurality of client devices, storing the encoded report payloads in a database, transferring at least one encoded report payload from the database into randomly addressable memory (RAM), decoding the at least one encoded report payload in RAM, parsing the decoded data in RAM with at least one matching algorithm to determine the occurrence of events, compiling a database of parsed data, and generating an AMS report from the database of parsed data.

A mobile service reception method and a mobile service receiver are provided. The mobile service reception method includes performing a channel scan operation comprising searching in one or more frequencies for a broadcast signal which includes mobile data for providing a mobile service and generating a list of a plurality of mobile services, selecting at least one mobile service from the list, and processing mobile data for the selected at least one mobile service by obtaining at least one parade through which the selected at least one mobile service is transmitted, wherein a parade forms one Reed Solomon (RS) frame or two RS frames.

A mobile terminal capable of receiving mobile broadcast services and a channel control method for the same are provided. The channel control method includes outputting broadcast data present in a frame received on a current channel during a frame transport interval, scanning, during a sleep interval after the frame transport interval, for at least one frequency corresponding to a preset preference channel, extracting channel information by parsing a frame carried by the scanned frequency, and storing the extracted channel information while updating existing channel information. Hence, the channel search time experienced by the user for viewing channel information may be shortened.
摘要:
A channel determination apparatus and method for a broadcast receiver are provided. The method includes estimating, when the broadcast receiver operates in a sleep state over a preset time period, inter-modulation distortion interference of a plurality of channels by scanning the channels, and receiving, when the sleep state is transitioned to an active state, broadcast data on a channel having the least inter-modulation distortion interference. Accordingly, the inter-modulation distortion interference of individual channels is taken into account to select an optimum channel, thereby resulting in improvement of channel determination accuracy.
摘要:
The determination and identification of channels in a signal is an important aspect of the operation of a signal receiver. A method (800) is described including the steps receiving (802) a signal containing a plurality of channels, filtering (806) the signal to produce an indicator of a channel band edge, and determining (818) a characteristic of the channel based on the indicator. Additionally, an apparatus (300) is described including a spectrum shift circuit (304) that receives an input signal and shifts the frequency spectrum of the signal, a filter (306) that filters the frequency shifted signal to produce an indicator of a band edge of a channel, and a signal analysis circuit (316, 318) that determines a characteristic of the channel based on the indicator of the band edge, the signal analysis circuit (316, 318) controlling the frequency shift in the spectrum shift circuit (304) based on the determined characteristic of the channel.
