Description

IMAGE DISPLAY DEVICE WITH TRANSPONDER LIST UPDATE FUNCTION
The present invention relates to an image display device having an automatic transponder list update function called in a periodical manner and requiring no user intervention.
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 unperformable in a time-saving manner.
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.
Assuming that a TV service may have hundreds of channels, configuring transponder information for a significant number of channels on a manual basis might take some serious time. It is to be noted that an image display device can be factory-configured such that transponder information is preloaded for a plurality of channels. In this case, the image display device will already be ready for the first use.
Alternatively, users can initiate auto-scan function to automatically retrieve channel-specific transponder information, also based on a preloaded transponder list. Since a satellite’s actual transponder list can change in a non-negligible frequency, a channel whose transponder information is not updated will be viewed, when channel surfing, as a blank screen and the channel-specific transponder information will continually be maintained in the transponder list. The situation may typically lead to an extent that an extensive amount of transponder information is not usable but preserved in the list. Further, it is also to be noted that unused transponder information is not be replaced as new entries are recorded.
Accordingly, configuration of transponder settings can be better managed and users can be offered a less troublesome viewing experience without having to manually delete and/or update unused transponder data on a continual basis. The present invention therefore solves the technical problem of accelerating management of transponder-related inaccurate or outdated data in association with a satellite’s transponder list in an automatic and periodical manner such that a given user needs not manually fiddle with the setting of each transponder.
Among others, one of the prior art disclosures in the technical field of the present invention can be referred to as US6055431, which defines a method controlling the operation of multiple beam antenna systems in communication satellite transponders. The method controls the coverage area assignments, frequency assignments, transmitted power level assignments, and component allocation assignments of these multiple beam antenna transponders in response to the existing and time varying demands for satellite resources. The method manages the operation of the satellite transponders to optimize the overall capacity of the communication satellite.
The present invention therefore provides a system and method by which an image display device is operable so as to automatically manage configuration of transponder settings as provided by the characterizing features defined in Claim 1.
Primary object of the present invention is to provide a system and method by which management of transponder-related inaccurate or outdated data of an image display device is carried out in an automatic and periodical manner.
The present invention proposes a method for operating an image display device, having an automatic transponder verification function. This function is automatically called, upon setting a time interval by the user such that the image display device periodically performs automatic transponder verification action such that transponder information in association with a respective satellite is processed and channels that exhibit no signal error are automatically cleared on confirmation.
According to the present invention, transponder information in respect of channels that have no signal error are automatically copied into an internal memory of the image display device in the form of a temporary channel list including removed channels and respective transponder information. The transponder information for each channel in said temporary channel list is then rechecked at the end of the subsequent time interval as set by the user.
Accompanying drawings are given solely for the purpose of exemplifying a system and method by which an image display device is operable to automatically manage configuration of transponder settings, whose advantages over prior art were outlined above and will be explained in brief hereinafter.
The drawings are not meant to delimit the scope of protection as identified in the claims nor should they be referred to alone in an effort to interpret the scope identified in said claims without recourse to the technical disclosure in the description of the present invention.
Fig. 1 demonstrates a general flow diagram according to which the image display device of the invention executes the method of clearing unused channel transponder information list.
The present invention proposes an image display device enabling a user to automatically configure transponder settings of a plurality of channels without having to manually spend a significant amount of time in an effort to individually configure transponder settings for each channel.
It is known that digital and interactive TV systems provide a comprehensive amount of TV channels and programs and each channel has specific transponder information, a transponder typically receiving a television signal from the satellite uplink stations on the ground and encoding, amplifying and rebroadcasting the same. Transponder parameters can typically involve satellite name, transponder frequency in MHz, polarization, symbol rate in Ksym/s etc.
An image display device can be factory-configured such that transponder information is preloaded for a plurality of channels. However, a satellite’s actual transponder list can change in time and it can expand to accommodate new entries along with old ones, a channel whose transponder information is not updated being typically viewed as a blank screen when channel surfing. In this case, the user can rearrange the transponder list by selecting a respective menu in the interface environment, which is not easily directly accessible in certain cases, and must repeat the same action each time an outdated entry is encountered.
To this end, the image display device of the present invention regularly initiates transponder information verifying function and determines channels that receive no signal. In this way, an automatic clearing function is performed such that non-verified transponder entries with no signal response are automatically deleted.
The proposed method of the invention is implemented in the following manner. The image display device is first configured by the user to fulfil automatic verification action on a periodical manner and the time interval for the automatic verification action is set. The image display device has an automatic clearing function by which outdated transponder entries in the transponder list in association with a respective satellite are cleared on confirmation and the respective channels are removed from the channel list.
In this way, no blank screen with the ‘no signal’ error message will be encountered. The removed channels and respective transponder information are, however, automatically copied to a temporary channel list and the transponder information for each channel in the list is rechecked at the end of the subsequent time interval as set by the user. In this regard, the invention also ensures that the channels with no signal error can be automatically relocated back.
In a nutshell, the present invention proposes a method for operating an image display device such that automatic transponder verification action is performed, the image display device comprising an internal memory, the method for operating the image display device comprising the steps of, a) receiving time interval information to fulfil automatic transponder verification action on a periodical manner, b) performing automatic transponder verification action such that channel-specific transponder information in association with a respective satellite is processed and channels that exhibit no signal error are automatically cleared on confirmation, upon which outdated transponder entries in the transponder list are deleted, c) automatically copying removed channels and respective transponder information to a temporary channel list stored on the internal memory and, d) rechecking the transponder information for each channel in the temporary channel list at the end of the subsequent time interval as set by the user.
According to an embodiment of the present invention, transponder information in respect of a channel which previously exhibited no signal error but presently functioning properly is carried over into the list of regular channels.
In a further embodiment of the present invention, transponder information in respect of channels which previously exhibited and presently exhibit no signal error are deleted at the end of the subsequent time interval.
In this regard, the present invention ensures that configuration of transponder settings is better managed and users are offered a more comfortable viewing experience where no channels with blank screen are encountered. Further, the users do not have to manually delete and/or update unused transponder data on a continual basis. The present invention therefore solves the technical problem of accelerating management of transponder-related inaccurate or outdated data in an automatic and periodical manner such that a given user needs not manually fiddle with the parameters of each transponder.
