Title: System and method for customized message playback

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS/INCORPORATION BY REFERENCE 
     None. 
     FIELD 
     Various embodiments of the disclosure relate to data communication and media processing. More specifically, various embodiments of the disclosure relate to a system and method for customized message playback. 
     BACKGROUND 
     Various electronic devices, such as security or surveillance systems, may be used in premises, such as a household, an office, or an industrial establishment, to secure entrances, occupants, and/or other valuable goods in the premises. The electronic devices may also serve to interface between visitors and occupants of the premises. For instance, when a visitor arrives at household premises, the visitor may press a doorbell button at an entrance of the premises, which may output a bell or tune from the doorbell to an occupant of the household premises. When the bell or tune is played, the occupant may become aware of the arrival of a visitor at the household premises. In certain scenarios, the doorbell may be integrated with the security or surveillance system of the premises. For example, a camera (such as a CCTV camera) associated with a surveillance system may capture images of the visitor. The captured images of the visitor may be displayed to the occupant of the premises via an electronic device situated inside the premises or associated with the occupant. However, such existing systems may not provide a user-centric experience customized to both the visitor and the occupant(s) of the premises. An advanced eco-system may be required to not only enhance security of the premises, but also provide a platform that may augment usability of a smart security system while providing an enhanced experience to the end-users. 
     Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

Further, the registration may enable the second electronic device  106   a  to transmit media items to other electronic devices for storage or play back on that electronic device. 
     In accordance with an embodiment, when the first user  104  visits the premises  120 , the first electronic device  102  may detect arrival of a visitor based on a pre-specified proximity of the first user  104  to the first electronic device  102 . In accordance with an embodiment, an input on the first electronic device  102 , such as a press a push button (not shown) may indicate an arrival of the first user  104  at the premises  120 . The first electronic device  102  may prompt the first user  104  to provide a voice sample through the microphone  214 . In addition, the image-capturing unit  212  may capture one or more images of the first user  104 . 
     In accordance with an embodiment, the user recognition circuitry  218  of the first electronic device  102  may be configured to determine one or more physiological and/or behavioral characteristics of the first user  104 . The one or more physiological and/or behavioral characteristics may be determined based on facial recognition, voice recognition, and visit trend analysis. The facial recognition, voice recognition, and visit trend analysis steps are illustrated in  FIG. 3 , as processing steps  302   a ,  302   b , and  302   c , respectively. 
     At processing step  302   a , the user recognition circuitry  218  of the first electronic device  102  may send the captured one or more images, such as facial images, of the first user  104  to the server  110  for analysis. The server  110  may store a repository of facial images of known users. The server  110  may apply one or more pattern detection or face detection techniques and/or one or more image processing techniques to identify one or more facial features of the first user  104 . Thereafter, the one or more facial features may be compared with pre-stored facial features in the repository of facial images to determine an identity of the first user  104 . 
     The user recognition circuitry  218  may receive the identified one or more facial features and determined identity of the first user  104  from the server  110 . In addition to the one or more facial images, the user recognition circuitry  218  may also transmit one or more full-length images (that capture complete body or a portion of the body) of the first user  104  to the server  110  for analysis. Based on the one or more full-length images, the server  110  may determine one or more other physiological and/or behavioral characteristics, such as a clothing pattern, an emotional state, a current activity of the first user  104 , and/or one or more objects held (such as books, knife, or other objects) or worn by the first user  104 . The clothing pattern may indicate a profession, such as a doctor, a postman, or age of the first user  104 . The server  110  may transmit these determined physiological and/or behavioral characteristics to the first electronic device  102 . 
     At processing step  302   b , the user recognition circuitry  218  may send the captured voice sample of the first user  104  to the server  110  for analysis. The server  110  may include a repository of voice samples of known users. The server  110  may apply one or more sound filters on the voice sample of the first user  104  to obtain an audio signature of the voice sample. Thereafter, the server  110  may compare the obtained audio signature of the voice sample of the first user  104  with pre-stored audio signatures of the voice samples of known users stored in the repository of voice samples. Based on the comparison of audio signatures, the server  110  may determine the identity of the first user  104 . The processor  202  of the first electronic device  102  may receive the identity of the first user  104  from the server  110 , via the first communication network  116 . The identity of the first user  104  may be determined and cross-checked based on a combination of facial recognition (based on the one or more facial images) and voice recognition (based on the voice sample). 
     At processing step  302   c , the user recognition circuitry  218  of the first electronic device  102  may transmit a request to the server  110 , via the one or more transceivers  206 , for analysis of a visit trend of the first user  104 . The request may include the identity of the first user  104 , current date and time, and the determined one or more physiological and/or behavioral characteristics of the first user  104  in the present visit to the premises  120 . The server  110  may include a repository of attributes of known users correlated with identity of the known users and visit history log of previous visits of the known users to the premises  120  and/or other premises of other known users. 
     On receipt of the request from the user recognition circuitry  218 , the server  110  may use the identity of the first user  104  to retrieve records associated with the first user  104  from the visit history repository. The retrieved records may include visit history log of the previous visits of the first user  104  to the premises  120  and the correlated one or more attributes of the first user  104 . In accordance with an embodiment, the server  110  may analyze the visit history log to determine past trends of the one or more physiological and/or behavioral characteristics of the first user  104 . Further, the server  110  may correlate the presently determined one or more physiological and/or behavioral characteristics of the first user  104 , received from the first electronic device  102 , with past trends determined from the analyzed visit history log. 
     Based on the correlation, the server  110  may determine one or more current attributes of the first user  104  in accordance with the received one or more physiological and/or behavioral characteristics of the first user  104 . The user recognition circuitry  218  and/or the processor  202  of the first electronic device  102  may receive the determined one or more attributes of the first user  104 , from the server  110 . Further, the server  110  may update visit history repository including the visit history log associated with the first user  104  to include details related to the current visit of the first user  104  to the premises  120 . The details related to the current visit of the first user  104  may include the determined one or more current attributes of the first user  104 . 
     At processing step  304 , the processor  202  of the first electronic device  102  may retrieve one or more media items from a plurality of media items based on the determined one or more current attributes of the first user  104 . In accordance with an embodiment, the server  110  may store a repository of media items including the plurality of media items. The processor  202  of the first electronic device  102  may send a query for retrieval of the one or more media items to server  110 . The query may include the determined one or more current attributes. Alternatively, the plurality of media items may be stored in the memory  204  of the first electronic device  102 . The processor  202  may retrieve the one or more media items from the memory  204 , in such a case. Examples of the one or more attributes may include, but not limited to, an identity of the first user  104 , a profession of the first user  104 , an event associated with the first user  104 , a date-of-interest associated the first user  104 . The one or more attributes may further include a type of relationship between the first user  104  and the second user  108   a , a visit history of the first user  104 . In addition, the one or more attributes may include a pre-configured schedule of visit of the first user  104  to the premises, and/or a purpose of visit of previous visits of the first user  104  to the premises  120  or other premises. 
     For example, the one or more attributes may indicate that the identity of the first user  104  is “Peter”. Thus, the one or more retrieved media items may be customized for “Peter”, such as a custom tone and a welcome message for “Peter”, based on the pre-specified preferences. In another example, if the first user  104  may be an individual with a profession of “postman” (determined based on the clothing pattern), the first user  104  may be greeted accordingly. Further, a custom media item may be retrieved and played back in this case, which may instruct the first user  104  to place the new mails and/or periodicals in a mailbox. A password or location of a key of the mail-box may be provided to the first user  104  through the custom message in case the first user  104  may be identified as a trusted/known postman based on the visit trend analysis. 
     In another example, if an event and/or date-of-interest associated with the first user  104  match with the current date and/or time of identification, a media item may be accordingly selected from the plurality of media items for play back to the first user  104 , via the speaker  216 . Examples of such events and/or date-of-interest may include, but not limited to, a birthday, an anniversary, and/or an academic or sports performance of the first user  104 . For instance, a birthday tune may be selected from the plurality of media items, in case the first user  104  has a birthday on the day of visit to the premises, a previous day (belated birthday), or a next day (upcoming birthday). 
     In another example, the media items retrieved from the plurality of media items may be based on a type of relationship between the first user  104  and the second user  108   a . For instance, three relationship types, such as family-and-friends, neighbors, and acquaintances/others, may be specified by the second user  108   a  via the user interface of the pre-installed application. Accordingly, different media items may be retrieved for the first user  104  who may belong to a particular relationship type. In addition, the retrieval of media items from the plurality of media items may also be based on the visit history of the first user  104 , pre-configured visit schedule, and/or purpose of previous visits of the first user  104  to the premises  120 . For instance, a technician of a consumer electronic good, such as a television, refrigerator, air conditioner, washing machine, and/or dish washer, may periodically visit the premises  120  to undertake service of the consumer electronic good installed in the premises  120 . The periodicity may be quarterly or annual based on service requirement of the consumer electronic good and a service contract of the second user  108   a  with the technician&#39;s organization. Thus, once the technician is recognized and visit schedule and purpose of visit of the technician correlate with details of previous visits stored in the visit history log, custom media items may be retrieved for the technician. For example, a welcome message followed by details associated with the relevant consumer electronic goods may be provided as an audio/video output to the technician through the first electronic device  102 . The details associated with the consumer electronic goods may be retrieved from the server  110 , which may store a repository that may maintain such information. 
     In accordance with an embodiment, once the one or more media items are retrieved at processing step  304 , the processor  202  may transmit the one or more media items to pre-registered one or more electronic devices. The second electronic device  106   a  may be an example of such electronic device, which may be pre-registered to receive custom messages and/or alerts from the first electronic device  102 . The processor  202  may transmit the retrieved one or more media items to the second electronic device  106   a , via the first communication network  116 , through the one or more transceivers  206 . The one or more media items may be transmitted for playback at the second electronic device  106   a.    
     At processing step  306   a , the processor  202  may playback a media item from the retrieved one or more media items for the first user  104  on the first electronic device  102 . The selection of the media item for the playback to the first user  104  may be based on one or more pre-configured instructions or preferences received from the second electronic device  106   a , during pre-registration of the second electronic device  106   a . Video content of the media item may be played back on the display screen  210 , while audio content of the media item may be played back through the speaker  216  of the first electronic device  102 . 
     For the second electronic device  106   a , at processing step  306   b , the second electronic device  106   a  may also receive at least one of the retrieved one or more media items for playback to the second user  108   a  (the occupant of the premises  120 ) on the second electronic device  106   a . The play back may be based on one or more pre-configured instructions or preferences of the second user  108   a  set during pre-registration of the second electronic device  106   a . The second electronic device  106   a  may playback the received media item to the second user  108   a , via a user interface of the application, of the second electronic device  106   a . In accordance with an embodiment, different media items from the retrieved one or more media items may be played back on the first electronic device  102  and the second electronic device  106   a.    
     In accordance with an embodiment, instead of (or in addition to) transmitting the one or more media items, the processor  202  may transmit an alert message to the second electronic device  106   a , at the processing step  304 . The alert message may include a first media item from the retrieved one or more media items. The first media item may be selected from the one or more retrieved media items based on the one or more attributes of the first user  104  and/or one or more pre-specified preferences of the second user  108   a .

One or more other network devices may be grouped into a second group associated with neighbors of the second user  108   a.    
     In addition, the second user  108   a  may specify rules related to selection or play back of media items for network devices that belong to different groups. For instance, messages/alerts related to a visit by a user (such as the first user  104 ) to the premises  120  of the second user  108   a  may also be sent to each network device that belongs to a friends and family group, such as the first set of network devices  514 . This may be the case when the second user  108   a  is out of station. Further, the messages/alerts related to a visit of the first user  104  of a specific type (such as a postman) may be sent to each network device that belongs to group of network devices belonging to neighbors of the second user  108   a . For instance, through the playback of custom messages/alerts, the neighbors may be requested to keep the mail and/or periodicals related to the occupants of the premises  120  of the second user  108   a.    
     In accordance with an embodiment, the first user  104  may visit the premises  120  of the second user  108   a  and use the first electronic device  102  installed in the premises to send a custom message/alert to the second user  108   a . The first electronic device  102  may determine one or more physiological and/or behavioral characteristics of the first user  104 . The first user  104  may be identified based on a combination of facial recognition (based on one or more facial images of the first user  104 ) and/or voice recognition (based on voice sample of the first user  104 ). The first electronic device  102  may then determine one or more attributes of the first user  104  based on the determined one or more physiological and/or behavioral characteristics, as explained in  FIGS. 1 and 3 . 
     In accordance with an embodiment, when the first user  104  visits the premises of the second user  108   a , first electronic device  102  may transmit a notification to the second electronic device  106   a  indicating arrival of a new user. The notification may further request the second electronic device  106   a  to transmit current location information associated with the second electronic device  106   a  to the first electronic device  102 . As shown in  FIG. 5 , at processing step  502 , the second electronic device  106   a  may transmit the current location information associated with the second electronic device  106   a  to the first electronic device  102 .

That is, the retrieved media item may include a custom greeting for the known user and the second user  108   a  and also indicate the type of the first user  104  and other attributes of the first user  104 . This retrieved media item may be sent to the network device (such as the first network device  112   a ) of the known user (such as the first remote user  114   a ). The reception and playback of the pre-specified media item by the first network device  112   a  is illustrated by processing step  510   c.    
     The playback of the pre-specified media item on the first network device  112   a  may be controlled based on pre-specified configuration instructions received along with the communicated media item, from the first electronic device  102 . In accordance with an embodiment, the pre-specified configuration instructions may be received from the second electronic device  106   a  (of second user  108   a ) during pre-registration of the first network device  112   a  and/or the second electronic device  106   a . For instance, the pre-specified configuration instructions may direct the first network device  112   a  to playback a portion of the received media item and then playback an alert tone. Further, the first network device  112   a  may be directed to send the received media item to an electronic device, such as a smartphone, of the first remote user  114   a  if no response is received from the first remote user  114   a  within a predefined time interval. 
     In accordance with an embodiment, another media item may be retrieved for play back on the first set of network devices  514 . The other media item may indicate the one or more attributes (such as type of the first user  104 , purpose of visit, etc.) and also include a custom message for users of the first set of network devices  514 . For instance, the custom message may include a preferred tune or greeting for each user of the first set of network devices  514 . The selection of first set of network devices  514  from the plurality of network devices  112  based on the location information of the second user  108   a  is explained above in processing step  506 . In accordance with an embodiment, the other media item may be selected from the one or more retrieved media items based on the current location information of the second user  108   a  and the determined one or more attributes of the first user  104 . For instance, the first set of network devices  514  include network devices of friends and family who may receive custom messages and alerts when the second user  108   a  is out of station.
