Method for rendering a multimedia content and a navigation interface on a screen

An entity for managing, in a reader terminal, streaming of a televisual content, called a main content, and of a navigation interface concomitantly from a telecommunication network, the navigation interface comprising regions including contents representative of real-time televisual contents available for selection, which contents are called secondary contents, the main content being streamed in the form of chunks having a plurality of time-variable encoding bit rates including a lower bit rate and a higher bit rate, an encoding bit rate for the main content being selected as a function of an available bandwidth of the telecommunication network, wherein a secondary content of the secondary contents available for selection has a plurality of image qualities, and wherein the entity comprises:

• processor;
• and
• a non-transitory computer-readable medium comprising instructions stored thereon which when executed by the processor configure the entity to:
• prior to receiving a command to display the navigation interface, define an encoding-bit-rate threshold value, which is higher than the lower bit rate and is not to be crossed when streaming the main content and the navigation interface concomitantly, the encoding-bit-rate threshold value being chosen among the plurality of time variable encoding bit rates independently of the available bandwidth of the telecommunication network;
• receive the command to display the navigation interface;
• define an image quality chosen among said plurality of image qualities, said image quality being chosen such that the encoding bit rate-used for the streaming of the main content remains higher than said defined threshold value;
• and
• transmit a request to access the secondary content of the interface, the request including a datum representative of the defined image quality;
• and
• receiving both main content with a bit rate higher than said threshold value and the secondary content with the defined image quality.

A non-transitory computer-readable data medium on which at least one sequence of program-code instructions has been stored, which when executed by a processor of a multimedia-stream reader terminal configure the multimedia-stream reader terminal to manage streaming of a televisual content, called a main content, and of a navigation interface concomitantly from a telecommunication network, the navigation interface comprising regions including contents representative of real-time televisual contents available for selection, which are called secondary contents, the main content being streamed in the form of chunks having a plurality of time-variable encoding bit rates including a lower bit rate and a higher bit rate, an encoding bit rate for the main content being selected as a function of an available bandwidth of the telecommunication network, wherein to a secondary content of the secondary contents available for selection has a plurality of image qualities, and wherein the managing comprises:

• prior to receiving a command to display the navigation interface, defining an encoding-bit-rate threshold value, which is higher than the lower bit rate and is not to be crossed when streaming the main content and the navigation interface concomitantly, the encoding-bit-rate threshold value being chosen among the plurality of time variable encoding bit rates independently of the available bandwidth of telecommunication network;
• receiving the command to display the navigation interface;
• and
• defining an image quality chosen among said plurality of image qualities, said image quality being chosen such that the encoding bit rate-used for the streaming of the main content remains higher than said defined threshold value;
• transmitting a request to access the secondary content of the interface, the request including a datum representative of the defined image quality;
• and
• receiving both main content with a bit rate higher than said threshold value and the secondary content with the defined image quality.
