Transmission apparatus, reception apparatus and transmission/reception apparatus for image and/or audio data and other than image and/or audio data
First Claim
1. A transmission apparatus including at least one processor for transmitting data in a predetermined protocol, said transmission apparatus comprising:
- first communication-protocol-processing means for carrying out necessary processing in accordance with a predetermined communication protocol on image and/or audio information as data to be transmitted by using hardware;
second communication-protocol-processing means for carrying out necessary processing in accordance with the predetermined communication protocol on predetermined information other than said image and/or audio information as data to be transmitted by using software, the second communication-protocol processing means carrying out the necessary processing at a speed lower than that of the first communication-protocol processing means;
transmission means for outputting and transmitting data being transmitted; and
connection-switching means capable of selecting said first communication-protocol-processing means or said second communication-protocol-processing means as means to be connected to said transmission means, based on an amount of data received per unit time, so as to select transmitted data processed by said first communication-protocol-processing means, taking precedence of transmitted data processed by said second communication -protocol- processing means,wherein an amount of data per unit time processed by the first communication-protocol-processing means is required to exceed a predetermined value to sustain a time-series continuity, while an amount of data per unit time of the second communication-protocol-processing means has no such a requirement.

Abstract
The present invention provides a transmission/reception apparatus capable of achieving both a high processing speed and good extensibility in performing communication protocol processes. Used for transmitting data in accordance with a predetermined communication protocol and receiving data transmitted in accordance with the predetermined communication protocol, the transmission/reception apparatus has a configuration capable of executing communication protocol processes by using hardware (in first and second communication-protocol-processing units) and software (in first and second control units). The hardware or the software can be selected properly in accordance with the type of data. For example, a communication protocol process for data regarded as a heavy processing load can be carried out by using the hardware at the high processing speed whereas a communication protocol process for data regarded as a light processing load can be carried out by using the software, which offers the good extensibility.
