It is assumed that a reception processing unit receives a broadcast program in accordance with tuning based on the user's specification. In this state, a non-viewable state detection processing unit monitors occurrence of a non-viewable state from an acquisition state of reception data. When the non-viewable state occurs due to a certain factor, a non-viewable state accumulation unit accumulates information on the non-viewable state. When the factor of a viewing interruption is solved and a user makes a request for service provision, the processing unit connects to a distribution apparatus to report content of the non-viewable state, and receives distribution of a relevant content, thereby the processing unit becomes able to recontinue interrupted broadcast content.

In a transport stream distribution system, a transmission rate control unit takes in an IP packet output from an IP transmission processing unit, obtains a TTS to be added to an arbitrary TS packet in the IP packet, and compares the TTS with a time stamp generated internally to determine whether both of them coincide with each other or not. And if they coincide with each other, the system takes in a TTS of the next TS packet, and otherwise, the system obtains a difference between a time indicating the TTS and the time indicating the internally generated time stamp to calculate a transmission rate correction value equivalent to the value of the difference, and issues the calculated correction value to the processing unit to correct a transmission rate.

File sharing system

A broadcast signal received by a broadcast signal reception unit is separated into program contents and program information by a broadcast signal separation unit. The separated program contents is converted into Internet Protocol (IP) packets by a contents transmission unit then distributed to an IP network. A program information transmission unit converts the separated program information into the IP packets then distributes the IP packets by setting an IP connection differing from that of the transmission unit. A terminal device receives the program contents by a contents reception unit to supply it to a program contents reproduction unit. The program information received by a program information reception unit is stored in a program information memory and output to a display in response to an output request.

An exchange system which comprises a plurality of line setting processors and a line-setting-signal path management processor for connecting the line setting signal paths of lines to the plurality of line setting processors. Each of the line setting processors judges whether or not the associated line is activated. When a line setting processor determines that the line is activated, it informs the line-setting-signal path management processor of this fact. The line-setting-signal path management processor determines, on the basis of the loads of the line setting processors, a suitable one of the line setting processors to be connected to the line setting signal paths of the activated line, and connects the suitable line setting processor to the line setting signal paths. Communication of necessary data is carried out between the line-setting-signal path management processor and the plurality of line setting processors so that even when a new line setting processor is added in the system, a maintenance operator can avoid complicated load estimation.

A packet exchange network comprises a plurality of packet exchange nodes connected through trunk lines and terminals connected to the packet exchange nodes each of which is provided a packet storage buffer for storing received packets. When the buffer cannot store every incoming packet due to 'traffic congestion,' some of the packets are discarded from the buffer by examining and registering the number of relay packet exchange nodes through which the packet passes during the communication at the time of setting a call to start a packet communication and by positively changing a discard rate of packets to be discarded at each relay packet exchange node on the basis of the registered packet exchange node number, so that all the packets have substantially the same discard rate regardless of the relay packet exchange node number.

A data transmission control system in which each terminal sends to a node connected to the terminal a call setting signal including data transmission band parameters such as best and worst band values and call priority required for call setting. Each node manages the data transmission band parameters for each call, the node when detecting generation of a call with high priority calculates a new data transmission band of an associated call with low priority as necessary, and sends a control signal for change of the data transmission band to the terminal handling the associated call even during communication of the associated call. The terminal changes the current data transmission band to the data transmission band indicated by the control signal to thereby control the data transmission band even when the terminal is in a communication state, whereby line traffic can be flattened and line operating efficiency can be increased.
