Abstract:
A method of coordinating the delivery of two independent messages, of different mediums, for simultaneous presentation is provided. The messages are communicated in a system capable of including coordination plans with the messages. The coordination plans include the identity of the independent messages, points in the messages where the coordination begins, and the duration of the presentation. Once linkage points in the first and second messages are defined, the relationship between messages is defined, so that independent messages 10 are displayed with predefined, meaningful timing. In communication system flexible enough to support real-time, two-way communications, such as wireless telephones, at least one of the messages to be coordinated can be received and presented in real-time. A system of coordinating two independent messages with a coordination plan message is also provided.

Description:
BACKGROUND AND SUMMARY OF THE INVENTION 
     This invention relates generally to communications and, more particularly, to a system and method of synchronizing a multi-media message communication. 
     A system is typically considered to have multi-media capabilities if it can simultaneously present different types of information mediums. Specialized computer applications have been developed for some systems to permit a user to integrate independent streams of information. Shelley et al., U.S. Pat. No. 5,345,551 disclose a system permitting a computer operator to manually synchronize information streams. Koval et al., U.S. Pat. No. 5,333,299 disclose a software program, stored in computer memory, capable of embedding synchronization signals into master and slave information streams. Neither system permits real-time synchronization of the independent data streams. The multiple information mediums must undergo a separate process of synchronization before the information is presented in the synchronized form. Further, neither system operates flexibly enough to support the convenient transfer of two-way messages between people. 
     Current mobile and land-line communication systems allow voice, data, and sometimes video information to be communicated in real-time, or near real-time. However these systems do not support the delivery of multi-media information streams, as only one type of information medium is communicated. That is, current communication systems do not simultaneously communicate multiple information mediums. Further, these system do not provide a means of synchronizing a second medium of information with a communicated medium of information. 
     It would be advantageous if multiple information mediums could be delivered in a format ready for presentation. 
     It would be advantageous if multiple information mediums could be delivered with synchronization instructions. 
     It would be advantageous if information coding, delivery system, and synchronization instructions could be embedded in a standard communication system, such as a telephone, or a network-linked computer. 
     It would be advantageous if at least one stream of information could be received, synchronized, and presented with a second stream of information in real-time. It would also be advantageous if the two streams of information could be of different medium types. 
     Accordingly, a method for presenting information from a first source, synchronously, with at least a second source of information is provided. The method comprises the steps of: 
     a) accepting instructions to control the acceptance and management of the first and second information sources; 
     b) accepting the first source of information; 
     c) accepting the second source of information; 
     d) in response to instructions accepted in Step a), synchronizing the information of the second source with information of the first source; and 
     e) presenting the synchronized information of both the first and second sources. 
     The information streams and management instructions are communicated in a variety of ways. For example, three distinct physical channels, or time multiplexed data groupings may be provided. In a TDMA system these channels may be different slots, and the function of the slots may be adaptive, changing in response to internal, or base directed software commands. In a CDMA system the three channels may be different orthogonal spreading codes. The three channels permit Steps a)-c) to include accepting the management instructions, and the first and second sources of information. 
     Step d) includes selecting a bit, or some other conveniently identified part of the first source of information as a coordination point which is synchronized to the starting bit of information in the second source. Then, Step e) includes presenting the starting bit in the second source in response to presenting the coordination point in the first source. That is, a point in the first source is chosen as a reference for synchronization. 
     To fine-tune the synchronization of the information streams a further step, following Step d), selects a delay to define the time duration between the coordination point in the first source and the starting bit in the second source. Then, Step e), delays the presentation of the starting bit in the second source from the presentation of the coordination point in the first source. Likewise, a time duration is selected for the presentation of the second source of information, and Step e) includes presenting the second source of information for the selected time duration. 
     Typically, the first source of information is a first communication medium type, and the second source is a different communication medium type. The management instructions are used to establish the first and second source medium types. The medium types are presented in Step e) in response to the communication medium types established. In this manner, the synchronization method is able to integrate different types of communication medium. Typically, the first and second communication medium types are selected from the group consisting of audio, audio/video, video, text, images, and data. For example, Step d) may include synchronizing the audio information of the second source with the audio/video information of the first source, so that a voice is dubbed over an audio/visual presentation. 
     Specifically, the management instructions may include a field devoted strictly to synchronization. This so-called Inter-Medium Coordination Management Field defines the synchronization of the first and second sources of information, with a series of sub-fields to define the medium types of each source, the identity of each source, the number of bits in the second source, the presentation length of the second source, the coordination point in the first source, and the delay between the coordination point and the beginning the second source presentation. 
     The method of the present invention is not necessarily limited to synchronizing two streams of information. In one aspect of the invention a Step c 1 ) accepts a third source of information and Step a) includes accepting management instructions to control the acceptance of the third source. Then, Step d) includes synchronizing the information in the third source with information in the first source, and Step e) includes presenting the synchronized information of the first, second, and third sources. 
     The present invention is useful in almost any communication system including, but not limited to, wireless systems such as those of the IS-95, W-CDMA, IS-136, and GSM standards. 
     A receiver has also been provided to synchronize at least two independent streams of information for real-time presentation. The receiver comprises at least a first communication channel having an input to accept at least a first stream of modulated information. The channel down-converts, demodulates, and decodes the information part of the received signal. The information is either received with embedded management instructions, or the instructions and information are received on separate channels. An instruction processor accepts management instructions. The instruction processor creates information stream management commands in response to the instructions. 
     A synchronizer, having a first input connected to the first communication channel output, accepts information streams. A second input connected to the instruction processor output accepts management commands. The synchronizer synchronizes the first and second information streams in real-time as the first information stream is accepted by the first communication channel. At least a first information presentation unit, having an input connected to the synchronizer output, presents the first stream of information simultaneously with the acceptance of the first stream of information by the first receiver channel. In this manner, two streams of information are synchronized for real-time presentation. A second presentation unit, having an input connected to the synchronizer output, presents the second medium type, when the two information streams are different medium types.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIG. 1 is a flow chart illustrating a method for synchronously presenting information. The present invention is useful in multi-media, e-mail, and wireless communications. Step  10  provides a wireless communication systems including at least one base station, the present method permits a mobile station to synchronize the presentation of a first communication stream to the presentation of at least a second communication stream. In some aspects of the invention, the first and second sources of information are provided by base station, e-mail sender, and memory. The wireless communication system is selected from the group consisting of IS-95, W-CDMA, IS-136, and GSM. 
     In an e-mail system, for example, a realtor may send a pre-existing video (with sound) clip of a listed house as one source of information. The realtor may choose to dub their voice over parts of the video to point out special features of interest to a specific client. The two independent mediums are sent to the client with the synchronization instructions. When the client opens their e-mail, the synchronization instructions automatically present the video and voice dubbing with the timing arranged by the sender (realtor). 
     In a wireless system, a client (receiver) has their telephone attached to auxiliary presentation equipment, such as a video monitor. As above, a video of a house is sent as one piece of data, and the realtor (sender) sends a voice commenting on features in the video. Technically, it is challenging to send both pieces of information and the synchronization instructions in real-time, so that the client sees the presentation of information at approximately the same time that it is sent. The sender may send the video at an earlier time, or access a video record stored in the memory of the client&#39;s receiver. Then, the sender can trigger the presentation of the previously sent video, and make comments on the video, creating synchronization commands. 
     Step  12  accepts instructions to control the acceptance and management of the first and second information sources. In a wireless system management fields of instructions are received to control the reception of the first and second communication streams. The management instructions are grouped into octets, fields, packets, or messages depending on the specific communication system. Hereafter, the term “management instructions” is intended to include any such possible grouping of data. Step  14  accepts the first source of information. In a wireless system, the first communication stream of information is received. Hereafter it is understood that the terms “communication streams” and “sources” are substantially interchangeable. Likewise, Step  16  accepts the second source of information. In a wireless system, the second communications stream of information is received. The order of steps  12 ,  14 , and  16  are somewhat arbitrary. In some aspects of the invention, the information is received before the management instructions. In other aspects, the information is received after the instructions. Further, the information and instruction segments are received in cycles or in changing order in response to the nature of the information or management considerations in the communication system. 
     Step  18 , in response to instructions accepted in Step  12 , synchronizes the information of the second source with information of the first source. Step  20  presents the synchronized information of both the first and second sources. Alternately, Steps  18  and  20  are considered to be combined so that the second communication stream of information is synchronously presented with the first communication stream of information in response to the instructions received in Step  12 . Step  22  is a product, where two independent information sources are synchronized, or two independent communication streams, or data sources are joined, or coordinated with the use of the accompanying coordination plans in Step  12 . 
     In one aspect of the invention, a memory device is provided in Step  10  to store information and management instructions. Then, further steps (not shown), following Step  18 , occur. Step  18   a  stores the synchronized information of the first and second sources in memory, and Step  18   b  accesses the information stored in Step  18   a . In this manner, the information of the first and second sources is synchronously presented after being stored. Alternately, the memory device stores information and management instructions. Then, further steps (not shown) preceding Step  18  occur. Step  16   a  stores, in memory, the information of the first and second sources accepted in Steps  14  and  16 , respectively, and the management instructions accepted in Step  12 . Step  16   b  accesses the information and management instructions stored in Step  16   a . In this manner, the information of the first and second sources is stored before processing into synchronously linked data sources. 
     In one aspect of the invention at least three communication channels are provided in Step  10 . The definition of communication channel, as used herein, is very broad. In one aspect of the invention, the channels are distinct physical channels, such as different carrier frequency bands. Alternately, the channels are a single carrier that is time multiplexed. Further, the channels may be different time slots of a single physical channel. In a CDMA system the channels are data sent on a single carrier, at the same time, with different orthogonal spreading codes. In some aspects of the invention, the definition of the channels is adaptive, as the use and characteristics of time multiplexed slots change in response to broadcast commands, or receiver logic. The channels are also combinations of physical, time, frequency, and orthogonally coded messages. In some aspects of the invention, the channels are also specified as higher layers of a layered hierarchical protocol structure such as Open System Interconnection (OSI) and Integrated Services Digital Network (ISDN) and are implemented in Software/firmware only to implement the time sharing of a physical channel. However defined, all three, or any combination of the information streams and management instructions are carried on one, two, or three channels. Steps  12 - 16  include accepting the management instructions, and the first and second sources of information on the three communication channels, however the channels have been defined. 
     Typically, the communications are digitally formatted, although the present invention&#39;s method also applies to analog formats. Whether the communication is organized in octets, packets, fields, messages or other groupings, the ultimate basis of information transfer is usually the bit. Given the nature of modern communications, even the analog Advanced Mobile Phone Service (AMPS) wireless system uses receiver equipment which digitizes data at some point in the receiving process. Step  18  includes selecting a bit in the first source of information as a coordination point synchronized to the starting point of information in the second source. For example, the coordination point could be the rising edge of the first bit in a specified field. Step  20  includes presenting the starting point in the second source in response to presenting the is coordination point in the first source. It is assumed for the purposes of this discussion that the location of the starting point in the second stream is a predetermined bit location, in accordance with a format known to all the communication players in the system. For example, the starting point is the first bit of the information to be presented in the second stream strip. Alternately, the starting point is a bit in the second stream of bits preceding, or subsequent to the actual bits of information to be presented. In some aspects of the invention, the starting point is defined by the management instructions in the same manner that the coordination point is defined. Regardless of the exact location of the coordination point in the first stream and the starting point in the second stream, once references are taken in the two streams, it becomes possible to synchronize the streams. 
     Generally, the information streams and the management instructions are communicated in a serial order, so that a first bit precedes a second bit in time. However the method of the present invention applies equally well to parallel data transfer systems where a number of bits arrive simultaneously. Even in parallel processing systems, groupings of data are handled in a serial sequence. Steps  14  and  16  include accepting, respectively, first and second sources of information in a sequentially order, and Step  12  includes accepting sequentially ordered fields as the management instructions. Then, Step  18  includes selecting a coordination point in a sequence of bits in the first source. 
     The method includes further steps, following Step  18 . Step  18   c , in response to instructions from the management fields accepted in Step  12 , selects a delay which defines the time duration between the coordination point in the first source and the starting point, or bit in the second source. Step  20 , in response to the time duration selected in Step  18   c , includes delaying the presentation of the starting point in the second source from the presentation of the coordination point in the first source. The synchronized presentations are finely adjusted with a delay, after coarse adjustment with the coordination point. 
     Step  18   d , in response to instructions from the management fields accepted in Step  12 , selects a duration for the presentation of the second source of information. Then, Step  20  includes presenting the second source of information for the time duration selected in Step  18   d . Once the starting point, delay, and duration are known, the synchronization of the second information stream to the first information stream is completely described. 
     In some aspects of the invention, the first source provided in steps  10  is a first predetermined communication medium type and the second source is a second predetermined communication medium type. Further steps, then, follow Step  16 . Step  18   e  establishes the first source first communication medium type in response to accepting the management fields in Step  12 . Step  18   f  establishes the second source second communication medium type in response to accepting the management fields in Step  12 . Then, Step  20  includes presenting information fields of the first source in response to the communication medium type established in Step  18   e , and also includes presenting information fields of the second source in response to the communication medium type established in Step  18   f . In this manner, the synchronization method is able to integrate different types of communication medium. 
     The first and second communication medium types provided in Step  10  are selected from the group consisting of audio, audio/video, video, images, text, and data. The method includes broadcast quality audio as well as compression schemes such as a variety of vocoders, Adaptive Delta Modulation (ADPCM), and μ-law PCM, as are well known in the art. The audio/video medium includes full motion, slow motion, and slow scan video. Data medium includes images, animation, text, moving images, graphs, and abstract pictures. In some aspects of the invention, Step  10  provides a receiver, audio/video information as the first medium type, and audio information as the second medium type. Steps  12 - 16  include accepting the management fields and first and second source information fields, respectively, with the receiver. For example, when Step  10  provides a audio/video first medium type and an audio second medium type, Step  18  includes synchronizing the audio information of the second source with the audio/video information of the first source. In this manner, a voice is dubbed over an audio/visual presentation. 
     Step  10  provides for a plurality of information streams, with each source having a unique message identification number. For example, each information stream is given an identification number in an octet of data before, or after the information. In some aspects of the invention the information is also supplied with the management instructions. The identification number is supplied with the management channel, and the correlation between each information stream and identification number is made through timing relationships. Then, Step  12  includes accepting a first source message identification number and a second source message identification number in the management fields. Step  14  includes selecting the source with the first source message identification number, and Step  16  includes selecting the source with the second source message identification number. 
     FIG. 2 is a example of management instructions organized in accordance with IS-95 standards (prior art). Although the IS-95 is specifically described, the method applies equally well any communication system, especially one which communication system data and management instructions. The functions of the pre-existing field names and assignment values in the Channel Assignment Message are defined in section 7.7.2.3.2.8 of IS-95, Revision B. The pre-existing values of ASSIGN_MODE are “000” to “101”, representing a traffic channel assignment, paging channel assignment, acquire analog system assignment, analog voice channel assignment, extended traffic channel assignment, extended paging channel assignment. To implement a new field to control synchronization, a new ASSIGN_MODE with a value greater than “101” is created, such as “110” to define the synchronization field and function. 
     FIG. 3 is an example of the synchronization field, called the Inter-Medium Coordination Field, part of the Channel Assignment Message, organized in accordance with IS-95 standards. Returning to FIG. 1, Step  12 , in response to receiving the management fields, identifies an Inter-Medium Coordination Field in a message, such as the Channel Assignment Message. In this manner, synchronization is conducted in the context of established communication management protocols. Step  12  includes accepting an Inter-Medium Coordination Management Field to define the synchronization of the first and second sources of information. These sub-fields, or sub-steps (not shown) identify the first and second information streams, the coordination point, the duration, and the medium types (also see FIG.  3 ). 
     Step  12   a  accepts a first sub-field (S 1 _MEDIUM_ID) to define the first source first medium type. In the IS-95 example of FIG. 3, the S 1 _MEDIUM_ID field is ½ of an octet in length. Step  12   b  accepts a second (S 1 _MESSAGE_ID) sub-field to define the first source message identification number, whereby a specific sequence of information is identified as the first source in Step  14 . In the IS-95 example, S 1 _MESSAGE_ID has a length of 1 octet to identify the first communication stream. Step  12   c  accepts a third sub-field to define the second source second medium type. In the IS-95 example, S 2 _MEDIUM_ID is a field of ½ an octet to identify the second communication stream medium type. 
     Step  12   d  accepts a fourth sub-field to define the second source message identification number, whereby a specific sequence of information is identified as the second source. In the IS-95 example, S 2 _MESSAGE_ID is a field of 1 octet to identify the second communication stream in Step  16 . Step  12   e  accepts a fifth sub-field to define the size of the second source information stream. Typically, the number of bits or octets in the second source of information, whereby the amount of information in the second source is defined. In the IS-95 example, a S 2 _LENGTH field has a length of 1 octet identifies the number of octets in the second communications stream. 
     Step  12   f  accepts a sixth sub-field to define the presentation duration of the second source. In the IS-95 example, S 2 _RUN_LENGTH field has a length of 1 octet to identify the presentation time duration of the second communications stream. Step  12   g  accepts a seventh sub-field to define the coordination point in the first source of information from which the synchronization of the second source is referenced. In the IS-95 example, COORD_PT_ID_IN_S 1  is a field of ½ an octet to identify a reference point in the first communications stream to synchronize the second communication stream with the first information stream. 
     Step  12   h  accepts an eighth sub-field to define the delay between the coordination point established in sub-field  12   g  and the start of the presentation of the second source information stream. In the IS-95 example, START_OF_PLAY_DELAY is a field of 1 octet to identify a time delay, from the presentation of the coordination point until the presentation of the first information stream with the second communications stream. 
     In some aspects of the invention three, or more information streams are synchronized. A further step, precedes Step  18 . Step  16   c  (not shown) accepts a third source of information, and Step  12  includes accepting management instructions to control the acceptance of the third source. Then, Step  18  includes synchronizing the information in the third source with information in the first source, and Step  20  includes presenting the synchronized information of the first, second, and third sources. Alternately, Step  18  includes synchronizing the information in the third source with information in the second source, and Step  20  includes presenting the synchronized information of the first, second, and third sources. 
     In some aspects of the invention, only one information stream is communicated. That is, the user already has the second information stream on hand, or in memory. A first information stream is communicated and synchronized with the information stream already on hand. A memory device is provided in Step  10  for the storage of sources of information, and Step  16  includes accepting the second source from memory. For example, a sender chooses an image residing in memory with the receiver for a visual background to an audio message. 
     In one aspect of the invention, at least one information stream is received and presented in real-time. Alternately, at least one information stream is received in real-time, but the user is presented the synchronized information at a later time. For example, when the user checks their e-mail. In another aspect of the method, the information streams and instructions are stored by the sender. The information streams and instructions are sent, synchronized, and presented to the user at the user&#39;s command. Once again, a user checking e-mail is an appropriate example. In such as system, a further step, preceding Step  12 , is required. Step  10   a  signals the base station to transmit communications including information sources and management instructions, whereby the information streams and management instructions are stored at the base station, and retrieved by the mobile station in real-time. 
     FIG. 4 is a flow chart illustrating another aspect of the method for presenting information synchronously. Step  60  provides a first source of information and at least a second source of information. Step  62  accepts the first source of information with embedded management information instructions. Step  64  accepts the second source of information. Step  66 , in response to instructions accepted in Step  62 , synchronizes the information of the second source with information of the first source. Step  68  is a product, where two independent data sources are coordinated with accompanying synchronization plans. 
     FIG. 5 is a schematic representation of a receiver  100  to synchronize at least two independent streams of information for real-time presentation. Receiver  100  comprises at least a first communication channel  102  having an input on line  104  to accept at least a first stream of coded information. Line  104  is operatively connected to antenna  106  in wireless communication embodiments of the invention. Alternately, line  104  is operatively connected to a physical line  108  such as coaxial line, or fiber optic cable for computer/e-mail embodiments. First channel  102  represents a wireless receiver circuitry or any other circuitry which receives modulated carrier signals, coded digital signals, or organized data for processing. Hereafter, first channel  102  will be said to decode information. First channel  102  has an output on line  110  to provide decoded information streams. 
     An instruction processor  112 , having an input on line  110 , accepts management instructions. Instruction processor  112  creates information stream management commands in response to the instructions, and has an output on line  114  to provide management commands. 
     A synchronizer  116 , having a first input operatively connected on line  110  to first communication channel  102  output, accepts information streams. A second input operatively connected to instruction processor  112  output on line  114  accepts management commands. Synchronizer  116  synchronizing the first and second information streams as the first information stream is accepted, or received by first communication channel  102 , in response to management commands, and provides the synchronized information streams at an output on line  118 . 
     At least a first information presentation unit  120 , having an input operatively connected to said synchronizer output on line  118 , presents the first stream of information simultaneously with the acceptance of the first stream of information by first receiver channel  102 . In this manner, two streams of information are synchronized for real-time presentation. As is well known in the art, even in real-time communication systems, information is not presented at exactly the same time that it is received, as there is some processing delay. However, the presentation is substantially simultaneous, and appears to be exact realtime to the user. 
     Typically, the first stream of information is a first medium type and the second stream of information is a second medium type. First presentation unit  120  presents at least the first medium type. Receiver  100  further comprises a second presentation unit  122  having an input operatively connected to synchronizer  116  output on line  118  to present presentation unit  120  presents at least the first medium type. Receiver  100  further comprises a second presentation unit  122  having an input operatively connected to synchronizer  116  output on line  118  to present the second medium type. In this manner, the first and second streams of information are synchronously presented. 
     In one aspect of the invention, the first and second information streams, and the management instructions are all accepted on first  102 , second  124 , and third  126  communication channels, respectively. As described above in the description of FIG. 1, the definition of the word channel is intended to be broad, to cover CDMA orthogonal coding, time multiplexing, as well as any construction and categorization of data by receiver  100 , and the communication system being used, in software. For convenience and clarity, first  102 , second  124 , and third  126  channels are depicted in FIG. 5 as physical channels. The output of first  102  and second  124  communication channels are operatively connected to synthesizer  116  input to provide decoded information. Third channel  126  output is operatively connected to instruction processor  112  input on line  128  to provide decoded management instructions. 
     Synchronizer  116  selects a point in the first stream of information as a coordination point, to reference the start of the presentation of the second stream of information with the first stream of information, in response to information stream management commands received on line  114 . In this manner, a point in the first stream is chosen as a reference for synchronization. 
     Synchronizer  116  selects, in response to management commands on line  114 , a delay which defines the time from the coordination point in the first stream of information to the start of the synchronized presentation of the second stream of information. Further, synchronizer  116  selects, in response to management commands on line  114 , a duration for the presentation of the second stream of information. 
     As demonstrated above in the discussion of FIGS. 1-3, the streams of information and management instructions are organized sequentially, and the management instructions include an Inter-Medium Coordination Field sub-fields as follows: 
     a first sub-field to define the first information stream medium type; 
     a second sub-field to define the first information stream message identification number, whereby a specific stream of information is identified as the first stream; 
     a third sub-field to define the second information stream medium type; 
     a fourth sub-field to define the second information stream message identification number, whereby a specific stream of information is identified as the second stream; 
     a fifth sub-field to define the size the second information stream, whereby the amount of information in the second stream is defined; 
     a sixth sub-field to define the presentation duration of the second information stream; 
     a seventh sub-field to define the coordination point in the first stream of information from which the synchronization of the second stream of information is referenced; 
     an eighth sub-field to define the delay between the coordination point established in the seventh sub-field and the start of the presentation of the second stream of information. 
     In some aspects of the invention, receiver  100  further comprises a first memory device  130  having an input operatively connected to synchronizer  116  output on line  118 . First memory device  130  stores the synchronized information streams. First memory  130  has an output operatively connected to the input of first presentation device  120  on line  118 , whereby the information of the first and second streams is synchronously presented after being stored. Alternately, a second memory device  132  having an input operatively connected to at least first communication channel  102  output on line  110 . In some aspects of the invention, line  110  operatively connects the outputs of second channel  124  to an input of memory  132  on line  110 , as shown in FIG.  5 . FIG. 5 also shows an output of third channel  126  operatively connected to an input of memory  132  on a line  134 . Second memory device  132  stores the first and second information streams and management instructions. Second memory device  132  has outputs operatively connected to the inputs of synchronizer  116  on line  114  and said instruction processor  112  on line  128 , whereby the information of the first and second streams is synchronized and presented after being stored. 
     The first and second medium types are selected from the group consisting of audio, audio/video, video, text, image, and data. For example, the first medium type is audio/video information and the second medium type is audio information. Then, first presentation unit  120  is a video monitor, with speaker, to present audio information from the second stream synchronized with audio/visual information from the first stream. Alternately, the second stream on audio information is presented on a separate speaker, on second presentation unit  122 . 
     In some aspects of the invention, receiver  100  synchronizes information from a third stream of information (a fourth physical channel is not shown). Then, instruction processor  112  creates commands to manage the third stream of information, and synchronizer  116  synchronizes the third stream of information with the first and second streams in response to the management commands on line  114 . 
     In some aspects of the invention, receiver  100  further comprising an information storage unit, or third memory  136  having an output on line  110  to provide the second stream of information, whereby information in memory is synchronized with real-time information.
