Problems solved by technology

Thus, increasing the complexity of the mechanism capable of exploiting the recorded data
[0020] Moreover, in the absence of time stamps associated with the subtitle data, the described problems associated with normal reading speeds are additionally exacerbated in slow motion mode, since the delay between displaying the subtitle and displaying the corresponding video image becomes more Big

Embodiment Construction

[0082] exist figure 1 In the illustrated modules are functional units which may or may not correspond to physically distinguishable units. For example, these modules or some of these modules can be combined together to form a single component, or to construct functions of the same software. Rather, certain modules may be constituted by separate physical entities.

[0083] Video decoding system 10 ( figure 1 ), such as a TV-type system equipped with a PVR designed to receive audio-visual programs received in the form of a stream F and either transmit them directly to the TV viewer or record them in a storage space 15 so that they can be accessed later These programs are reproduced, and the two operations described can be performed simultaneously. exist figure 1 , only the functionality associated with the record is shown.

[0084] In addition to a storage space 15 such as a hard disk, the video decoding system 10 includes:

Abstract

The present invention relates to a device (1) and a process for the read-synchronization of video data and of ancillary data, these data being recorded in a storage space (15) in multiplexed and chronological form. The synchronization device comprises modules for inputting (2) and demultiplexing (3) the recorded data, the video and ancillary data being respectively transmitted to video reading (20) and ancillary (30) assemblies, which read and communicate these data. It also comprises an apprising module (4) capable of obtaining information from the video reading assembly (20) as regards instants of communication of video data, and an adaptation module (5) designed to adjust instants of communication by the ancillary reading assembly (30) of the ancillary data, as a function of the information obtained by the apprising module (4). Applications to subtitling and to interactivity.

Description

technical field [0001] The present invention relates to a device and method for synchronously reading video data and auxiliary data and related products, and these data are recorded in a storage space in the form of multiplexing and time sequence. In particular, the invention applies to the synchronization management of teletext broadcast subtitles in record read control mode ("playback"). Background technique [0002] In digital television decoders associated with the memory function, audio, video, teletext / subtitle type and such as Other types of various streams described in particular in the MPEG (Motion Pictures Experts Group) and DVB (Digital Video Broadcasting) standards. Digital TV decoders such as are equipped with a Personal Video Receiver or PVR (Personal Video Recorder Standard) equipped with a built-in hard disk on which the stream is stored. [0003] Such various streams are usually transported in an MPEG transport stream, demultiplexed by a demultiplexer, and...
