Embodiment Construction

[0034] figure 1 shows a continuous stream F of digital video data used to encode a document c . and receive the stream F c A user equipped with a display terminal 112 connected to the decoder 100 can interrupt the display of the document when he is away and resume the display when he returns so that he can see the entire document.

[0035] Similarly, the user can speed up playback of the document to avoid the annoying segment, or reverse the display orientation of the document to view the segment again.

[0036] In order to perform such operations, the decoder 100 may comprise means 102 for storing digital video data; and means 104 for reading these stored data, such as application programs, for controlling the storage of data in the memory unit of the decoder. 108 and read the header 106 of the data. For example, the storage unit of the decoder is constituted by a recording medium such as a hard disk or an optical disk.

[0037] Also, the decoder includes a write pointer...

Abstract

The invention relates to a method of delayed reading digital video data stored in a file (200) on a recording medium (108). According to the method, a fixed amount of storage resources of a recording medium (108) is allocated to files (200) storing these data. Applied to the digital decoder.

Description

technical field [0001] The present invention relates to a method and device for delay reading digital video data. [0002] Video files encoded in the form of digital data offer a large number of processing possibilities. [0003] More specifically, the present invention relates to delayed reading of data recorded on a recording medium, which consists in recording a program on the recording medium in a file while simultaneously reading out the program with a certain delay. This application allows the user to suspend the read-out of a program when the user desires, and to resume the read-out from the point where the user paused the program. Background technique [0004] Known devices capable of implementing a method of delayed readout, in particular of the digital television decoder type, exhibit a number of drawbacks. [0005] Among these known devices, some propose methods in which the amount of storage resources that can be allocated to files other than delayed readout fi...
