CONTENT DISTRIBUTION SYSTEMS AND METHODS

FIELD OF THE INVENTION

The invention is in the field of content distribution.

BACKGROUND OF THE INVENTION

Historically dissemination of content was difficult. Printed books required the creator of the written content to hire a printer and/or publisher.

The development of recording technology made dissemination of sound based content feasible, but the creator of the sound content was still dependent upon a recording company and/or a music publisher/distributor.

Radio, and later television, opened channels of transient content distribution. Initially if you did not listen to/watch a broadcast, the content was unavailable.

The Internet caused an explosion in content distribution. It also empowered content creators to disseminate content independently.

Smartphones have proven to be another platform for content distribution in the form of ringtones and wallpapers.

SUMMARY OF THE INVENTION

A broad aspect of the invention relates to targeted content delivery by individuals. According to various exemplary embodiments of the invention the content being delivered includes audio and/or graphics and/or video and/or an applet.

One aspect of some embodiments of the invention relates to push of a ring-back tone while a call is being connected. These embodiments include presentation of content selected by a called party on a smart device of a calling party while the calling party is waiting for the call to be connected to the called party. In some exemplary embodiments of the invention, the content transfer is mediated by a remote server. Alternatively or additionally, in some embodiments the content selected by a called party is stored in advance on a server and retrieved by the calling party from the server using a unique identifier transmitted from the called party. In some embodiments the unique identifier is delivered with an applet that automatically downloads the content from the server based on the unique identifier.

According to another aspect of some embodiments of the invention a server receives a content item from a subscriber and links the content items to a telephone number of the subscriber in a database. In some embodiments a distribution mechanism of the server pushes the content item to a handset operated by a party calling the subscriber before the call is connected. In some exemplary embodiments of the invention, the distribution mechanism selects from a content item from many content items provided by the relevant subscriber according to distribution rules.

According to another aspect of some embodiments of the invention a server receives a content item from a first subscriber and links the content items to a telephone number of the subscriber in a database then pushes the content items linked with subscriber phone numbers to handsets of other subscribers (For example, subscribers in the contact list of the first subscriber) according to distribution rules. In some embodiments the pushed content items are unavailable to the owner of the handset until one of the other subscribers places a call to the first subscriber. Placement of the call unlocks the content item stored on the handset from which the call originated.

According to another aspect of some embodiments of the invention a handset of a subscriber receives and stores multiple content items pushed to it from a server. In some embodiments each content item is associated with a telephone number of a subscriber that uploaded it. In some embodiments an outgoing call from the subscriber causes presentation of a stored content item associated with the telephone number being called.

According to another aspect of some embodiments of the invention a calling party pushes a ringtone to a called party. According to these embodiments, the calling party transmits content to a called party concurrent with a phone call from the calling party to the called party. In some embodiments the content is presented on a handset of the called party before the call is connected. In some embodiments connection of the call cuts off the content.

For purposes of this specification and the accompanying claims, the term “ringtone” indicates content presented on a telephone handset (e.g. smartphone, phablet tablet or computer) to indicate an incoming call.

DETAILED DESCRIPTION OF EMBODIMENTS

The principles and operation of a system and/or method according to exemplary embodiments of the invention may be better understood with reference to the drawings and accompanying descriptions.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details set forth in the following description or exemplified by the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.

Embodiments of the invention relate to presentation of content on a telephone handset. For purposes of this specification and the accompanying claims, the term “telephone handset” includes any device capable of placing a telephone call. For purposes of this specification and the accompanying claims, the term “telephone call” indicates any transmission of a voice signal via a cellular network, VOIP or VOIP transmitted via cellular data service along at least a portion of its route.

In some embodiments ring-back content is selected by a called party and presented by a new protocol named Over IP (Internet Protocol) Ring Back Content (OIPRBC). This protocol makes presentation of visual content as part of “ring-back” possible for the first time. Addition of visual content is a significant improvement relative to conventional ring-back tones which are limited to audio. Alternatively or additionally, allowing a called party to set their own ring-back content is a significant departure from conventional practice in which the telephone service provider has exclusive control over ring-back tones.

In some embodiments ringtone content is selected by a calling party for presentation to a called party by a new protocol named Over IP (Internet Protocol) Ring Tone Content (OIPRTC). This protocol makes presentation of visual content as part of “ringtone” possible for the first time. Addition of visual content is a significant improvement relative to conventional ring tones which are limited to audio. Alternatively or additionally, allowing a calling party to set their own ringtone is a significant departure from conventional practice in which the called party has exclusive control over ringtones.

Specifically, some embodiments of the invention can be used to present content on a handset while a call is in the process of being connected. According to various exemplary embodiments of the invention content presentation is on the called party's handset and/or on the calling party's handset.

System Overview

FIG. 1 is a simplified system overview, indicated generally as 100, illustrating the operational context of various exemplary embodiments of the invention. Line CH-CH indicates the separation between voice channel (above the line) and data channel (below the line) for a conventional cellular telephone call. For video calls and/or VOW calls. The call itself is transmitted on a data channel, but the flow of data is similar.

FIG. 1 depicts a single calling party 110 and a single called party 120 for clarity of illustration, although a much larger number will be present in actual practice. “The word “party” is used to indicate the person holding the handset because the people view and/or hear presented content. However, the various functions described are performed exclusively by the handsets and/or servers. Alternatively or additionally, a single handset functions sometimes as a calling party and sometimes as a called party. In some embodiments handsets of calling party 110 and/or calling party 120 are configured with a software application that allows them to realize various features described hereinbelow.

In the depicted embodiment, calling party 110 places an outgoing call request 112 via a telephone server 150. Request 112 is routed to called party 120 as incoming call request 122. The incoming request 122 is either refused or answered 124 by called party 120. In case the call is answered server 150 connects 114 the call to calling party 110.

Some exemplary embodiments of the invention are based on the fact that the delay between outgoing call request 112 and connection 114 is significant. In the cellular telephone systems tested the average duration of delay was on 2.8 seconds for 20 MB network and 1.1 sec for 100 MB network. The distance between the devices has a negligible effect on the delay.

According to these embodiments, called party 120 pushes ring-back content 130 to the handset of calling party 110.

Alternatively or additionally, in some embodiments calling party 110 pushes ringtone content 140 to called party 120.

In some embodiments pushes content 130 and/or 140 involve direct transfer of the data file for the content between handsets 110 and 120 (in either direction). Alternatively or additionally, in some embodiments pushing of content is mediated by a content server 160.

In some embodiments calling party 110 and/or called party 120 upload content items (116 and 126 respectively) to server 160 for subsequent download 118 and 128 by called party and calling party respectively. According to various exemplary embodiments of the invention uploads (116 and/or 118) and/or downloads (126 and/or 128) are conducted in advance and/or in response to a specific call being placed.

In embodiments in which content server 160 is used for content transfer, content 130 and/or 140 is transmitted from handset to handset as a unique identifier (UID) for a content item. In some embodiments receipt of the UID at a receiving handset triggers download (126 or 128) and presentation of the content item specified by the UID.

In some embodiments owners of handsets (e.g. 110 and/or 120) subscribe to receive services provided via server 160. According to various exemplary embodiments of the invention subscription includes installation of software on the handset and/or sharing of a phone numbers and/or group tags from a contacts list with server 160 and/or provision of a user profile to server 160.

First Exemplary System

FIG. 2 is a schematic diagram of a system for providing ring-back content determined by a called party according to some exemplary embodiments of the invention indicated generally as 200.

Depicted exemplary system 200 includes a server 161 receiving a calling party's 110 phone number 110N and a called party's 120 phone number 120 when a telephone call is placed by the calling party's handset. In the depicted embodiment, a database 210 of content items uploaded to server 161 contains content items, each content item being associated with a telephone number of a party that uploaded it. In some embodiments database 210 resides in a cloud server.

Depicted exemplary system 200 also includes a content delivery mechanism 220a configured to push a unique identifier (UID) 230 of a specific content item uploaded to DB 210 by the called party to the calling party's handset 110 in response to receipt of 110N and 120N by server 161.

According to various exemplary embodiments of the invention the UID is a location in a local directory of calling party's handset 110 or a location in a remote directory (e.g. in DB 210). In some embodiments the UID is formatted as a phone number of a party that uploaded it plus a time/date stamp. In the depicted embodiment, content delivery mechanism 220a resides on server 161. In other exemplary embodiments of the invention, the content delivery mechanism resides on handset 120 belonging to the called party. In some embodiments server 161 is not operated by a service provider handling the telephone call from 110 to 120.

In some embodiments content delivery mechanism 220a pushes an applet 240 to the calling party's handset 110. Applet 240 causes automatic download and presentation of the specific content item indicated by UID 230. In other exemplary embodiments of the invention, software causing automatic download and presentation of the specific content item indicated by UID 230 is resident on handset 110.

In some embodiments an elapsed time between placement of the call by calling party 110 and onset of presentation of the specific content item indicated by UID 230 on said calling party's handset is less than 2 seconds, less than 1 second or less than 0.75 seconds or intermediate or shorter times. In contrast, for a called party aged 18 to 35 the average time for answering the phone is 8.66 seconds. For a called party aged 35 to 55 the average time for answering the phone is 12.33 seconds. This means that there are several seconds available for content presentation before the call is connected.
