Abstract
In a network system for sending data to a plurality of terminals, a data processing apparatus has a plurality of coding units that code outgoing data including at least video or voice data for transmission to terminals over a network. The data processing apparatus obtains information about the terminals, groups the terminals according to the information, and transmits the coded outgoing data obtained from each coding unit to a different group of terminals. Appropriate grouping of the terminals conserves both network and coding resources and enables the quality of the data transmitted to the terminals to be improved at a low cost.
Claims19
A data processing apparatus for coding outgoing data including video and/or voice information and transmitting the coded data to a plurality of terminals, the data processing apparatus comprising:
- a plurality of coding units for coding the outgoing data to generate coded outgoing data;
- a terminal information management unit for managing terminal information related to communication features of each of the plurality of terminals;
- a terminal grouping unit for grouping the plurality of terminals into a plurality of groups corresponding to respective coding units in the plurality of coding units, on the basis of the terminal information managed by the terminal information management unit;
- and
- a data transmitting unit for transmitting, to each one of the groups of terminals, the coded outgoing data coded by the corresponding one of the coding units.
A data processing method for coding outgoing data including video and/or voice information and transmitting the coded data to a plurality of terminals, the data processing method comprising:
- using a plurality of coding units to code the outgoing data and generate coded outgoing data;
- managing terminal information related to communication features of each of the plurality of terminals;
- grouping the plurality of terminals into a plurality of groups corresponding to respective coding units in the plurality of coding units, on the basis of the terminal information;
- and
- transmitting, to each one of the groups of terminals, the coded outgoing data coded by the corresponding one of the coding units.
