Problems solved by technology

Also, since OSG production is dependent on the VCR manufacturer, it is difficult to consistently deliver the same OSG
Although the ATV analyzes the program guide information in the transmitted MPEG2-TS and displays the analyzed program guide information on the OSG display, and the user enters the program number using the remote controller 11 of the ATV, the program number cannot be transmitted to the HD-VCR 20 , because the command to transfer the program number to the HD-VCR 20 is not defined

Embodiment Construction

[0034] For convenience of description, an advanced television (ATV) is taken as an example of an MPEG2-TS broadcast signal receiver, and a high-definition video cassette recorder (HD-VCR) is taken as an example of an MPEG2-TS recording / playback device. However, any equipment having a digital interface capable of transmitting / receiving MPEG2-TS can be substituted for ATV, and any MPEG2-TS recording / playback device can be substituted for HD-VCR, as will be seen in the following description.

[0035] In addition, only the HD-VCR 200 and the ATV 100 are connected by the IEEE 1394 cable 300 in order to simplify the structure of the multimedia system shown in FIG. 2 . However, other digital audiovisual equipment may also be connected to the ATV 100 and / or HD-VCR 200 by the IEEE 1394 cable 300 . In the multimedia system of FIG. 2, a remote controller (ATV remote controller) of an ATV is used. In recording mode, a multi-program MPEG2-TS is transmitted from ATV 100 to HD-VCR 200 . In...

Abstract

A multimedia system and method for transmitting and receiving program information are provided. There is a digital audio-visual device in the multimedia system, including: a receiver with a digital interface, used to receive the transport stream and generate a program information control command according to the program information received from the user, and used to transmit via the digital interface The control command and a multi-program transport stream. Other devices in the multimedia system can be controlled without adding additional hardware to the receiver.

Description

[0001] This application is a divisional application of the Chinese patent application No. 97118638.3 filed on September 22, 1997, entitled "Multimedia System and Method for Transmitting and Receiving Program Numbers". field of invention [0002] The present invention relates to digital audio-visual (A / V) equipment, and more particularly to a multimedia system for connecting several digital audio-visual equipment to each other with a digital interface. Background technique [0003] In digital audio-visual equipment, one device can be controlled by other devices, which is not possible in traditional analog audio-visual equipment. As an example, the High-Definition Digital Video Cassette Recorder (HD-DVCR) Consortium defines a command set called AV / CCTS (Audio-Visual Control Command and The 1394 serial bus is transmitted to the target control device (referred to as the "local device"). The IEEE 1394 serial bus described here is a standard related to high-speed data transmissio...
