Abstract
At one of the timings: during a period between the moment when one of terminals which performs transmission calls out a communication partner and the moment of response and at the timing after the communication between the terminals is complete; a server reads out content data from a database, converts the read out content data according to the conversion information based on reproduction at the terminal, and transmits the converted content data to the terminal. At this timing, the terminal reproduces the content data transmitted from the server.
Claims22
A method of providing a multimedia service in a multimedia communication system comprising a plurality of terminals and a server, the server being connected to said plurality of terminals, said sever processing call process signals of said plurality of terminals, and including a database in which are stored content data;
- said method comprising steps wherein:
- said server reads said content data from said database at either the timings of:
- (a) the interval from the time a call is made by a terminal, that performs call origination among said plurality of terminals, to a terminal among said plurality of terminals that is the communication partner of said terminal that performs call origination, until the terminal responds;
- or
- (b) after completion of communication between said terminals;
- at said timing, said server either converts syntax of content data that have been read or converts content data that have been read based on conversion information of at least one of:
- encoding method, encoding bit rate, frame rate, image size, profile, level, encoding options, encoding frame type composition, video packet size, intraframe spacing, intra-macroblock number, and quantization value that accord with reproduction in said terminals;
- at said timing, said server transmits said content data that have been converted to said terminals;
- and
- at said timing, said terminals reproduce content data that have been transmitted from said server.
A method of providing multimedia service in a multimedia communication system made up from a plurality of terminals and a server, said server being connected to said plurality of terminals, said server processing call process signals of said plurality of terminals, and having a database that stores content data;
- said method comprising steps wherein:
- said server reads said content data from said database in accordance with either:
- (a) a read signal that corresponds to a key that is entered, when said read signal is transmitted to said server by an origination-side terminal that is the terminal that performs call origination of said plurality of terminals;
- or
- (b) a read signal that corresponds to a key that is entered, when said read signal is transmitted to said sender by a termination-side terminal that is the terminal that is the communication partner of said origination-side terminal of said plurality of terminals;
- said server either converts syntax of said content data that were read or converts said content data that were read based on conversion information of at least one of:
- encoding method, encoding bit rate, frame rate, image size, profile, level, encoding options, encoding frame type composition, video packet size, intraframe spacing, intra-macroblock number, and quantization value that accord with reproduction in said terminals;
- said server transmits said content data that have been converted to said terminals;
- and
- said terminals reproduce content data that have been transmitted from said server.
A method of providing a multimedia service in a multimedia communication system that is made up from a plurality of terminals and a server, said server being connected to said plurality of terminals, said server processing call process signals of said plurality of terminals, and having a database in which are stored character strings that can be displayed on said terminals;
- said method comprising steps wherein:
- said server reads said character string from said database in accordance with either:
- (a) a read signal that corresponds to a key that is entered, when said read signal is transmitted to said sender by an origination-side terminal that is the terminal that performs call origination of said plurality of terminals;
- or
- (b) a read signal that corresponds to a key that is entered, when said read signal is transmitted to said sender by a termination-side terminal that is the terminal that is the communication partner of said origination-side terminal of said plurality of terminals;
- said server inserts said character string that was read into image data that are transmitted and received between said origination-side terminal and said termination-side terminal;
- said server either converts syntax of said image data into which said character string was inserted or converts said image data into which said character string was inserted based on conversion information of at least one of:
- encoding method, encoding bit rate, frame rate, image size, profile, level, encoding options, encoding frame type composition, video packet size, intraframe spacing, intra-macroblock number, and quantization value that accord with reproduction in said terminals;
- said server transmits said image data that were converted to said terminals;
- and
- said terminals reproduce image data into which said character string was inserted, that were converted, and that have been transmitted from said server.
