Problems solved by technology

At the receiver level, the application cannot parameterize the display according to the user's wishes
As a result, the mosaic image includes thumbnails of all programs transmitted, including those that the user never selects, and, moreover, in an order that most likely does not match user preferences

Embodiment Construction

[0030] use figure 1 , the operation of the audio-visual receiver 1 connected to the display device 2 will be described first. The audiovisual receiver (e.g. a decoder, also called "set-top box") comprises a central processing unit 3 linked to a program memory 12, receiving means such as a demodulator 4, and means for receiving audio from a transmission network via a receiving antenna. / Demultiplexer for video data. Preferably, the receiver 1 is of the digital type and receives digital audiovisual services, however the invention can also be used in receivers of the analog type which receive channels transmitted by microwave channels. As a variant, the receiver 1 can be provided with an interface 5 to communicate with a broadband access digital network 6, making it possible to transmit audio / video data in real time. For example, the network is the Internet. The central processing unit must have high processing power to perform fast image processing, eg 200Mips. The receiver ...

Abstract

This invention permits a mosaic image to be presented to the user of an audiovisual receiver. The method includes a conceptual phase of a list of at least one audiovisual channel in order to display its contents in a mosaic image. The list is then sent to a server that broadcasts visual data associated with each channel on the list. The visual data are aggregated to comprise a mosaic image that is then displayed on the receiver. According to a first embodiment, the mosaic image is made in the receiver. According to another embodiment, the mosaic image is created in the server before being broadcast. According to an improvement, a channel is graphically highlighted in the mosaic image, and the receiver receives either the audio flow, video flow, or both from the channel highlighted. The invention also concerns the receiver capable of implementing the process.

Description

technical field [0001] The present invention relates to a method of displaying a user-personalized mosaic image in an audiovisual receiver, and an audiovisual receiver provided with such a display method. Background technique [0002] Currently, digital delivery networks transmit audiovisual programs desired to be viewed on audiovisual receivers, in particular service information enabling the selection of programs, for example by using electronic program guides. Patent FR2 713 427, filed by the applicant and published on June 9, 1995, describes a method of displaying a mosaic image and using this image to select a program. According to this prior art, the transmitter transmits a mosaic image comprising small images or "thumbnails" and a mapping table, each thumbnail graphically identifying the currently transmitted program, the mapping table making it possible to map the transmitted The program is associated with the position of the thumbnail in the mosaic image. Typically...
