A communication apparatus () includes: a communication unit () connectable to one end of a cable (); a first detection unit () which detects a maximum transmission capability of an external device based on a communication standard with which the external device complies, the external device being connected to an other end of the cable () connected to the communication unit (); a second detection unit () which detects a maximum transmission capability of the cable () connected to the communication unit (); and an alert output unit () which outputs an alert when the maximum transmission capability of the cable () is smaller than the maximum transmission capability of the external device, the maximum transmission capability of the cable having been detected by the second detection unit (), and the maximum transmission capability of the external device having been detected by the first detection unit ().

Communication apparatus, television receiver, video signal processing apparatus, communication method, program, and integrated circuit

A communication device includes: a wireless communication unit configured to perform data transmission and receiving with another communication device via a wireless network; and a communication control unit electrically connected with the wireless communication unit via a media independent interface (MII) bus and configured to control the wireless communication unit using a management data input-output/management data clock (MDIO/MDC) included in the MII bus.

A wireless video terminal (17) creates a control signal for requesting video data. This control signal includes the type of the requested video data, a method of transmitting the video data, a position registration request and the like. The wireless video terminal (17) requests the video data by transmitting this control signal to a video server (11) through a base-station for control-data (19) and a network (13). The video server (11) transmits the requested video data to the wireless video terminal (17) requesting the video data through a designated channel, via the network (13), a router for video-data (14) and a base-station for video-data (15).

Wireless video distribution system which avoids communication path

A ring network concentrator for dynamically changing the design of a network system depending on conditions of a ring network attached to the network concentrator. The ring network concentrator partitions traffic of a ring trunk network into a plurality of ring networks by dynamically changing connection patterns at configuration switches. The configuration switches connect ports, media access control units, and internal paths according to a communication protocol of a packet to be transferred and a traffic amount.
