Problems solved by technology

However, the digital TV 200 connected to the DVD player 100 through a digital interface such as the IEEE 1394 standard may not equip a processing capacity corresponding to the data processing capacity and the operation features of the DVD player 100, and may not support the characteristics of contents of the DVD in which aforementioned additional information and data for new functions are recorded.
Moreover, a low-price digital TV may not have information on its processing capacity and operational features, or may not support the negotiating function for mutual exchange of the feature information.
Accordingly, the video and audio data normally reproduced from a DVD by the DVD player may be presented abnormally in the digital TV.

Embodiment Construction

[0036]In order that the invention may be fully understood, preferred embodiments thereof will now be described with reference to the accompanying drawings.

[0037]FIG. 2 is block diagrams of a DVD player and a digital TV which the feature-dependent operating method between equippments connected each other through a digital interface is applied to. The DVD player 100 comprises an optical pickup 2 for detecting data recorded in a DVD 1; a demodulator 3 for demodulating and error-correcting the detected data; a scrambler 4 (or a copy protecting equipment) for scrambling data outputted from the demodulator 3 with copy protecting codes; a path selector 5 for selecting one or two output path for data scrambled with the copy protecting codes; a data parser 6 for parsing data streams, that is, PS received through the path selector 5 into presentation and navigation data and then parsing the presentation data into audio, video and sub-picture data again; decoders 7, 8, and 9 for decoding the p...

Abstract

The present invention relates to a method and apparatus for accomplishing a requested operation selectively based upon features of other equipment between equippments connected through a digital interface such as the IEEE 1394. The feature-dependent operating apparatus consists of a connector sending and receiving data through the digital interface; a memory storing feature information of a connected equipment received through the connector; a pickup detecting video and / or audio data from a data storage medium; a controller controlling the pickup to detect data from the data storage medium based on the stored feature information, converting the format of the detected data into a format specified in the stored feature information, and generating an advisory message informing a mismatch between the format of data to offer and the format specified in the feature information; and a data sender transmitting data detected by the pickup or the generated message to the connected equipment through the digital interface. This feature-dependent operating apparatus is able to adjust functions and processing capacity of a equipment to the maximal or universal capacity of the connected equipment automatically, or to inform a viewer of the cause of possible malfunction if the features of the connected equipment are not same, when data by a requested operation are to be transmitted to the connected equipment, thereby improving the convenience of a viewer.
