Definitions

  • This invention relates to a method of displaying a message sent over a digital radio or television wireless transmission network. It may be deployed to allow messages sent from a mobile telephone to be displayed oh a digital radio or television receiver.
  • Digital radio receivers are typically low cost receivers for receiving and playing audio broadcast by digital radio stations.
  • DAB digital audio broadcasting, based on the Eureka- 47 standard
  • PAD program associated data
  • X-PAD X-PAD
  • PAD can include the following data types: DLS (dynamic label segment) and MOT (multimedia object transport).
  • DLS dynamic label segment
  • MOT multimedia object transport
  • the present invention which in one implementation makes use of the pre-existing PAD capabilities of DAB receivers, overcomes this limitation.
  • a method of displaying a message sent over a digital radio or television wireless transmission network comprising the steps of:
  • a low cost digital radio or television receiver can be used to display messages specifically for the user of that receiver.
  • a 'digital radio receiver' should be construed as a radio receiver designed to receive broadcast (i.e. one to many) audio such as music and news programs; such a receiver is not therefore primariyl a one to one radio based text or audio communications device, such as a pager or mobile telephone. But the present invention enables such a receiver to combine its primary role of receiving broadcast audio with a new role of receiving and displaying messages that may be one to one (or indeed also one to a group of individuals belonging to a common group).
  • a digital radio receiver is not limited to any specific digital radio system, and hence includes DAB, DRM, HD radio and any other digital radio system or standard.
  • a 'digital television receiver' should be construed as a television receiver designed to receive broadcast (i.e. one to many) television such as music and news programs; such a receiver is not therefore primariyl a one to one radio based text or audio communications device, such as a pager or mobile telephone.
  • a digital television receiver is not limited to any specific digital television system, and hence includes DVB, DNB-H and any other digital television system or standard. DETAILED DESCRIPTION
  • the core idea in one implementation is to be able to use the digital radio network to carry text messages that can be received and displayed by low-cost digital radio or television receivers.
  • the digital radio receiver is modified to hold an ID that is unique to each user or user group.
  • An infrastructure server holds a database mapping the details of individuals to their unique ID. It also contains-details about the interest groupings to which the individuals belong, if any (this is to enable one-to-many messaging) as well as preferred carriers and stations (e.g. BBC1 or Virgin Radio). Note that an individual can belong to many user groups.
  • the ID of the individual and any applicable user group(s) is entered into the radio by the end-user and stored in Non-Nolatile memory
  • An implementation at the infrastructure side would be envisaged to be connected to a mobile phone operator text-messaging gateway. Then, to send a message to someone or a specific group the present 'text to radio' implementation of the invention, an end user could simply send a text (e.g. SMS, or other similar or successor/ enhanced formats) in a normal manner from the mobile telephone, perhaps to a special 'virtual' telephone number provided by the operator.
  • a text e.g. SMS, or other similar or successor/ enhanced formats
  • the digital radio receiver There exist a number of scenarios for distribution to the digital radio receiver: 1. the text message could be targeted at an individual. In this case the receiver will display the message or a message received indication to allow the user to read the message. 2. the text message may be targeted at a specific user group (e.g. local church group).
  • the receiver will display the message or a message received indication to allow the user to read the message.
  • This scenario could be used for business applications where specific information is to be distributed, most likely time sensitive information.
  • the text message may be targeted at the listeners of a specific radio station and possibly a specific program (e.g. breakfast radio).
  • the message may be edited by the station and may be displayed through the DLS rather than a specific message 'window'.
  • the window can take many forms from a simple 1 line scrolling display to a graphics based rendering.
  • One possible address scheme would be to use mobile numbers as the ID, where one digit could be changed, or a prefix code used, to differentiate the 'text to radio' address from the conventional mobile number.
  • a specific group-related addressing scheme could be used, for example where the number contained the individual's ID as well as a set of 1 or more tags which define the relevant user groups which should obtain the text message.
  • the text message would be delivered by the mobile phone operator's gateway to the DAB broadcast infrastructure, where it would be encoded into a form suitable for carriage as a DAB data service. It is anticipated that the messages would be highly compressed; a range of scheme exist for such compression:
  • the message is specific to a particular radio station is could be carried in PAD or XPAD, or if it is to be distributed across an entire ensemble the FIC may be used although the available bandwidth will be limited. 2.
  • the methodology in 1 could be used or the DLS could be used. Indeed the DLS style scrolling could be multiplied on the screen such that the standard station DLS appears along with (for example above or below) the specific user group message.
  • a secondary channel For targeted listeners of specific radio stations a secondary channel, a dedicated packet channel or PAD /XPAD could be used.
  • a given target message may have to be sent out multiple times in order to maximise the probability of reception.
  • the receiver can respond in a number of ways.
  • One of the simplest would be to simply show the message repeatedly scrolling across the display of the receiver (DLS style) until the user presses a 'stop' button.
  • DAB radios have the ability to display rolling text (DLS) so this option should be relatively low cost to implement.
  • Another possibility would be for the receiver to use voice synthesis to 'speak' the message using the radio's speakers.
  • the receiver may take some action, such as changing channel, setting off an alarm, etc., when the message was received.
  • This option may be useful for emergency situations where all users local to an area need to take specific action, e.g. for a local transmission at a football ground when a fire breaks out or an emergency situation occurs iri a road or rail tunnel which has ' DAB ' rebroadcast.
  • the receiver is in effect acting to receive an emergency alarm message, it will also be useful for it to alert the user if radio reception drops below a threshold level so that it is not longer able to reliably receive the alarm message.
  • the receiver could store the message (if the receiver was fitted with memory) for later playback.
  • Subscription based services may require encryption so that group ID is not distributed freely.
  • An example of this would be to have a service locked to specific receiver platforms where the Group ID needs to interact with the unique identifying code within the radio before decryption and display can take place.
  • the text may also be converted to speech using a speech synthesiser.
  • This option should be user selectable and have an option to set the volume of the text to speech conversion.
  • An additional option would be to be able to set the relative levels of both the primary audio output and the synthesised speech. For example this would allow the primary audio to be reduced to say half the original volume or even muted while the text to speech audio is output.

Abstract

L'invention concerne un procédé d'affichage d'un message envoyé sur un réseau de transmission sans fil radio ou TV numérique. Ce procédé consiste (a) à recevoir le message au niveau d'un récepteur radio ou TV numérique possédant une ID unique, et (b) à n'afficher le message sur le récepteur que si l'ID unique correspond à un identificateur dans le message. Ainsi, un récepteur de radiodiffusion numérique de faible coût, tel qu'un récepteur DAB ou un récepteur de télévision numérique, peut être utilisé pour afficher les messages spécifiquement pour l'utilisateur du récepteur.
