BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a data transmission method for transmitting/receiving data on a network comprised of plural interconnected electronic equipment, and to an electronic equipment in such network. [0003] 2. Description of Prior Art [0004] In recent years, it is contemplated to interconnect variable equipment having ports for external communication, such as a set top box, oriented to e.g., digital satellite broadcasting, to construct a network, which is to be used. [0005] In such network system, each equipment packetizes e.g., MPEG data, over a network cable, such as serial buses, and transmits the packetized data as a transport stream. Meanwhile, in the above-described network system, there lacks support in the meaning of advising other equipment of discontinuity points in the stream, such as data transition points. [0006] Thus, if, in such network system, in communication between optional equipment, an unpredictable unusual stream which will cause changes in the time axis is suddenly inputted to a demultiplexer or decoder in the receiving side equipment, hang-up is occasionally produced in the demultiplexer or decoder. Also, in such network system, there is raised such a problem that an equipment which has received the unusual stream displays a noisy picture or destructs a speaker. SUMMARY OF THE INVENTION [0007] It is therefore an object of the present invention to provide a data transmission method for data transmission/reception in a network system in which there is no risk of an equipment displaying a noisy picture on data reception or outputting an abnormal sound which might destroy a speaker. [0008] It is another object of the present invention to provide an equipment in such network system. [0009] In one aspect, the present invention provides a method for transmitting data in which the data is transmitted/received on a network in which a plurality of electronic equipment are interconnected over a serial bus interface; and which includes a detection step of detecting the timing of inserting discontinuity information data indicating discontinuity of the contents into contents of the data to be recorded and/or reproduced for a recording medium and a step of inserting the discontinuity information data into the data on detection of the timing of inserting the discontinuity information data in the detection step. [0010] In this data transmitting method, the discontinuity information data of the data recorded and/or reproduced for the recording medium is inserted to indicate that the time axis of the data contents is being changed. [0011] In the method for transmitting data in which the data is transmitted/received on a network in which a plurality of electronic equipment are interconnected over a serial bus interface, according to the present invention, discontinuity information data indicating discontinuity of contents of data recorded and/or reproduced for the recording medium is inserted into the data on detection of the timing of insertion of the discontinuity information data. By so doing, the electronic equipment receiving the data outputted to outside is able to comprehend that the time axis of the data contents is changing to render it possible to evade hang-up of each component as well as to evade displaying a noisy picture or outputting an unusual sound which possibly destructs a speaker. [0012] In another aspect, the present invention provides a method for transmitting data in which the data is transmitted/received on a network in which a plurality of electronic equipment are interconnected over a serial bus interface and which includes a detection step of detecting the timing of inserting discontinuity information data indicating the discontinuity of the contents into contents received from outside through a communication medium different from the serial bus interface, and a step of inserting the discontinuity information data into the data on detection of the timing of inserting the discontinuity information data in the detection step. [0013] In this data transmitting method, the discontinuity information data of the data received from outside over a communication medium different from the serial bus interface is inserted to indicate that the time axis of the data contents is being changed. [0014] In the method for transmitting data in which the data is transmitted/received on a network in which a plurality of electronic equipment are interconnected over a serial bus interface, according to the present invention, discontinuity information data indicating discontinuity of contents of data received from outside over a communication medium different from the serial bus interface is inserted into the data on detection of the timing of insertion of the discontinuity information data. By so doing, the electronic equipment receiving the data outputted to outside is able to comprehend that the time axis of the data contents is changing to render it possible to evade hang-up of each component as well as to evade-displaying a noisy picture or outputting an unusual sound which might destruct the speaker. [0015] In still another aspect, the present invention provides an electronic equipment in which the data is transmitted/received on a network constructed by interconnecting a plurality of electronic equipment over a serial bus interface, and which includes means for generating discontinuity information data indicating discontinuity of the data, means for detecting the timing of inserting the discontinuity information data into contents of the data to be recorded and/or reproduced for a recording medium and means for inserting the discontinuity information data into the data on detection of the timing of inserting the discontinuity information data by the detection means. [0016] In the electronic equipment according to the present invention, the discontinuity information data of the data received from outside over a communication medium different from the serial bus interface is generated and inserted to indicate that the time axis of the data contents is being changed. [0017] In the electronic equipment of the present invention, in which the data is transmitted/received on a network constructed by interconnecting a plurality of electronic equipment over a serial bus interface, there is provided means for generating discontinuity information data of the data recorded on the recording medium, and the discontinuity information data generated by this generating means and which indicates discontinuity in the data contents is inserted into the data on detection of the timing for inserting the discontinuity information data. By so doing, the electronic equipment receiving the data outputted to outside is able to comprehend that the time axis of the data contents is changing to render it possible to evade hang-up of each component as well as to evade displaying a noisy picture or outputting an unusual sound which might destruct the speaker. [0018] In yet another aspect, the present invention provides an electronic-equipment in which the data is transmitted/received on a network constructed by interconnecting a plurality of electronic equipment over a serial bus interface, and-which includes tuning means for tuning data received from outside over a communication medium different from the serial bus interface and generating means for generating discontinuity information data of data received through the serial bus interface and/or the tuning means. The generating means inserts the generated discontinuity information data into contents of data received through the tuning means. [0019] In this electronic equipment, the discontinuity information data of the data received from outside over a communication medium different from the serial bus interface is generated and inserted to indicate that the time axis of the data contents is being changed. [0020] In the electronic equipment of the present invention, in which the data is transmitted/received on a network constructed by interconnecting a plurality of electronic equipment over a serial bus interface, there are provided tuning means for tuning data received from outside over a communication medium different from the serial bus interface and generating means for generating discontinuity information data of data received through the serial bus interface and/or the tuning means. The discontinuity information data generated by the generating means is introduced into the contents of data received by the tuning means. By so doing, the electronic equipment receiving the data outputted to outside is able to comprehend that the time axis of the data contents is changing to render it possible to evade bang-up of each component as well as to evade displaying a noisy picture or outputting an unusual sound which might destruct the speaker.
