Embodiment Construction

[0019] The present invention is explained in detail by taking an example of a sub-picture decoding unit of a DVD playback apparatus. In this exemplary embodiment, a rectangular detail area on the display is regarded as a sprite. The embodiments described herein assume that the television receiver is a display, in which case the control commands relate to commands that produce sprite displays on the television receiver. The sprites are displayed on the screen of the television receiver, which may include, for example, rectangular details in an image provided for displaying subtitles of a foreign language film. Of course, other applications for such sub-pictures are also conceivable. For example, error messages can also be displayed on the screen in this way, or they can be displayed after the user of the device calls up specific operating instructions. In this case, operating instructions can be stored in the device to be executed. For example, if the device to be operated i...

Abstract

An apparatus for processing a sequence of control commands for a unit (40) to be controlled is proposed. In this case, the apparatus has first decoding means (22) which are designed to decode a predetermined set of control commands. In this case, this predetermined set of control commands also contains an end command (CMD-END), which indicates the end of a control command sequence. In order also to be able to process control command sequences having control commands which are not contained in the predetermined set, the apparatus has further decoding means (23) which are designed in such a way that when an unknown control command (SET-BAREA) arrives, they react in the same way as when the end command (CMD-END) from the predetermined set of control commands arrives. Undefined states are thereby prevented. The proposal also encompasses a method for generating a sequence of control commands for a unit to be controlled, and a storage medium for storing control commands for a unit to be controlled.

Description

[0001] This application is a divisional application of an invention patent application with an application date of December 16, 1997, an application number of 97125481.8, and an invention title of "Control command sequence processing device and generation method and control command storage medium". technical field [0002] The invention relates to a device for processing a control command sequence for a controlled unit, a method for generating a control command sequence for the controlled unit, and a storage medium for storing the control command of the controlled unit. Background technique [0003] The invention is based on a device for processing the sequence of control commands of a controlled unit. Such a device is known at present because DVD (Digital Versatile Disc) playback devices newly added to the market have so-called sub-picture decoding units (Sub-picture Decoder), these sub-picture decoding units are designed accor...
