Definitions

  • the present invention relates to a signal processing device having transponder list update function, the update function, when called, effecting updating of the transponder list in a periodical manner.
  • Digital and interactive TV systems provide a comprehensive amount of TV channels and programs leading to the general outcome that conventional methods for configuring the operation of the image display device from among a plurality of setting parameters may become inefficient to the extent that it is basically unperformable in a time-saving manner.
  • An image display device may receive programs via cable or satellite broadcasting in the form of separate subscription formats. Considering the fact that a large number of television and multimedia services are being made available to consumers, methods for enabling the host, i.e. an image display device such as a TV set with a digital receiver-decoder to satisfactorily process the received services are required.
  • a transponder typically receives a television signal on the ground from satellite uplink stations and processes the signal by encoding, amplifying and rebroadcasting the same. Satellite receivers then transmit the same to a digital receiver of an end-user so that it is decoded and displayed on an image display device.
  • an image display device can be factory-configured such that channel information is preloaded for a plurality of channels, in which case, the image display device will be ready for the first use.
  • users can initiate auto-scan function to automatically retrieve channel-specific information, based on a preloaded frequency range or transponder information.
  • the present invention therefore substantially facilitates maintenance of the channel information.
  • US2010211978 discloses a network-enabled image display device sending a geographic location to an Internet server and in response receiving back a list of TV service providers for the location. A user selects a provider and the server in response downloads the channel map pertaining to the selected provider.
  • the present invention provides a system and method by which a signal processing device is operable so as to automatically manage configuration of channel settings in a substantially facilitated and non-intrusive manner without requiring additional actions on the part of the user.
  • Primary object of the present invention is to provide a system and method by which management of channel information in an image display device is carried out automatically in a periodical manner by which inaccurate or outdated settings are clearable.
  • the present invention proposes a signal processing device in the form of a receiver or image display device.
  • the signal processing device receives a plurality of broadcasting services by means of at least one satellite tuner supplying transport streams to a digital TV processor.
  • the digital TV processor periodically updates the transponder list by connecting to a network resource such as a remote server through a network connection.
  • the updating operation is carried out even if there was no signal lock failure during the most recent auto-scan or blind scan operation.
  • the signal processing device also connects to the remote server each time before initiation of the manual or scheduled automatic scan function is to be effected.
  • the signal processing device also automatically connects to the remote server in a periodical manner to update the transponder list and automatically initiates channel scanning operation if an updated transponder list is available.
  • Fig. 1 demonstrates a general flow diagram according to which the signal processing device of the invention executes the method according to the present invention.
  • Fig. 2 demonstrates part of an exemplary xml file containing transponder parameters according to the present invention.
  • the present invention proposes a signal processing device in the form of an image display device or a set-top box receiving programs via satellite broadcasting for instance in the form of separate subscription formats.
  • a set-top box typically contains at least one tuner input, operating in connection with an image display device.
  • the image display device itself can receive programs using built-in satellite tuners.
  • Digital and interactive TV systems provide a comprehensive amount of TV channels and programs.
  • a conventional structure receiving program contents receives a transport stream via a tuner.
  • the receiver-decoder In order for viewing a first program content and processing a second program content, the receiver-decoder should have two tuners, which also enables various types of services including interactive functions such as picture-in-picture.
  • the tuners are typically connected to dish antennas collecting satellite signals to be focused by the parabolic curvature thereof.
  • signal received from a satellite dish is amplified by a low noise amplifier (LNA) and converted to IF signal (Intermediate frequency) in the form of a block of frequencies by a block converter (the LNB, low noise block downconverter), which can be then processed by the demodulators.
  • the demodulators typically output transport streams to the digital TV processor having an audio/video processing unit, which accordingly processes the transport streams and retrieves service data for all the channels.
  • the intermediate frequency is typically created by mixing the carrier signal with a local oscillator signal by heterodyning, which allows the signals in microwave frequencies to be sent over a length of cable.
  • the output of the mixer is an IF signal of a specific bandwidth that can be amplified.
  • transponder When processing the signal received from the satellite dish, specific transponder information of each channel is needed.
  • a transponder typically receives a television signal from the satellite uplink stations on the ground, encoding, amplifying and rebroadcasting the same.
  • Transponder parameters typically involve satellite name, transponder frequency in MHz, polarization, symbol rate in Ksym/s etc.
  • television broadcasting signals are searched and parameters such as frequency, symbol rate and polarization of a transponder are fed to the respective demodulator to verify whether signal lock is achieved.
  • a so-called blind search can be carried out in the manner that signals within the entire band are scanned or the signal processing device steps through a range of transponders.
  • the transponder list typically comprises transponders with different polarization (Vertical, horizontal) and low or high local oscillator frequencies.
  • the open standard Digital Satellite Equipment Control (DiSEqC) relies on DiSEqC messages carried on a modulated 22 kHZ tone in the form of sequences of short bursts communicated to the low noise block downconverter (LNB) by the receiver.
  • DiSEqC Digital Satellite Equipment Control
  • the image display device is factory-configured to have a satellite’s transponder list.
  • the actual transponder list of a satellite can expand in time so as to accommodate new entries along with old ones, a channel whose transponder information is not updated will typically be viewed as a blank screen during channel surfing.
  • the present invention proposes a system and a method for operating an image display device, having a transponder list updating function as delineated below.
  • the automatic function of the invention can be called on a periodical basis by setting a time interval such that an updated transponder list is obtained and channels that exhibit signal error are thereby automatically cleared.
  • the signal processing device of the present invention executes the method of updating the transponder list in the following manner:
  • the signal processing device is configured by the user to initiate automatic channel list retrieving function.
  • the signal processing device starts the channel information retrieving operation by way of connecting to a remote server through an Internet connection, the remote server containing an up-to-date list of transponders of the respective satellite.
  • the signal processing device carries out the transponder list updating operation irrespective of whether the most recent auto-scan or blind scan operation was terminated with no signal lock failure notifications. Therefore, the signal processing device periodically effectuates updating of the transponder list irrespective of the successful signal lock verification in relation to all of the present channels.
  • the signal processing device connects to the dedicated remote server each time before initiation of the manual or scheduled automatic scan function is to be effected. More preferably, the signal processing device automatically connects to the remote server in a periodical manner to update the transponder list and automatically initiates channel retrieving operation only if an updated transponder list is available.
  • the signal processing device keeps record of all of the previous transponder lists as downloaded from the remote server and in the event that an existing channel becomes unavailable and no transponder list update is available or a temporary interruption of Internet connectivity is in question, the transponder information stored in the earlier transponder lists is used to check whether older transponder parameters in relation to a given channel provide signal lock. This is especially advantageous in cases where new parameters are replaced by previous parameters, a situation observable on an infrequent basis.
  • the present invention ensures that the channel information retrieving operation carried out without intervention of the user is a stage during which the signal processing device also automatically updates transponders and accordingly retrieves associated channels.
  • the present invention proposes a signal processing device receiving a plurality of broadcasting services and comprising a digital TV processor and at least one tuner in association with a demodulator which supply transport streams, the signal processing device being further able to communicate with a display unit.
  • the digital TV processor is configured to periodically effect initiation of a transponder list updating operation by connecting to a dedicated remote server through a network connection irrespective of whether the most recent auto-scan or blind scan operation was terminated with no signal lock failure notifications or whether successful signal lock verification for all of the channels was obtained, whereby an updated transponder list is retrieved before a signal lock failure occurs.
  • the signal processing device connects to the remote server each time before initiation of the manual or scheduled automatic scan function is to be effected.
  • the signal processing device automatically connects to the remote server in a periodical manner to update the transponder list and automatically initiates channel retrieving operation if an updated transponder list is available.
  • the signal processing device keeps records of all of the previous transponder lists as downloaded from the remote server.
  • the signal processing device uses the transponder information stored in the earlier transponder lists to check whether older transponder parameters in relation to a given channel provide signal lock.
  • the signal processing device comprises at least one DVB-S or DVB-S2 tuner.
  • the signal processing device is an image display device or a set-top box.
  • the present invention ensures that configuration of channel information settings can be better managed in a less intrusive manner such that users are offered a less troublesome viewing experience without having to manually update transponders.
