Embodiment Construction

[0035] In this example, according to the MPEG 2 standard, the reception of satellite-based digital television packets consists in selecting the frequency (selection of transmission), receiving the corresponding compressed signal and transmission signal, and then, demodulating this signal, which is the "tuner" Features. The demodulated information is a transport stream (or TS in the MPEG2 standard), which consists of a string of packets converting several programs at a time.

[0036] The MPEG-2 Systems standard defines rules for multiplexing and identifying packets. Therefore, the next step is to select the packets corresponding to the desired program, which is a multiplexing function. This produces "Video", "Audio" and "Auxiliary Data" packets (these ancillary data are standardized and not to be confused with the additional data or auxiliary information of the present invention).

[0037] For each type of data, there is a corresponding special decoding:

[0038] --Video dec...

Abstract

A process for switching television programmes is characterized in that it detects (8, 9) and then stores (10) the appended data of intra type of programmes other than the selected programme, selects (10) and decodes (12), upon a command (14) for the switching over to a new programme, the stored appended data relating to this new programme, and temporarily transmits (13), while awaiting the decoding and transmission of the current data of the new programme, the decoded appended data. Applications relate for example to the perusing of programmes.

Description

technical field [0001] The invention relates to a method and device for quickly switching digital television programs. Background technique [0002] With the advent of digital television some years ago, the habits of television viewers have changed. Having already embraced the pay-per-view concept, he could be offered dozens of television programs by setting up satellite reception. The hallmark "number" associated with this new technology reassures consumers. For a large part of the public, especially since the advent of the CD, "digital" has become synonymous with "quality". [0003] However, potential purchasers of digital devices need not be aware of certain limitations regarding this new system. Due to the satellite reception, some functions of his equipment were no longer possible, for example, showing one program while recording another. He also has to wait a few seconds to switch from one program to another. [0004] Indeed, when the TV viewer indicates with the ...
