The disclosure relates to a method and apparatus including setting a memory swap size limit, the limit being lower than a memory swap size defining a maximum size of a part of said memory resources used for swap, obtaining a score for at least one running program, a high score corresponding to a low priority level, obtaining monitoring information representative of a monitored activity of the program during a time period and of a learnt user's habit of use of the program, including a number of times the program gained the focus within the time period. The disclosure also includes deriving a score delta from information with a decrement value to the score delta at each focus gained by the program, adjusting the score by adding the delta, and terminating execution when memory swap size limit is reached and the adjusted score reaches a memory swap size limit threshold.

After a stream transition event such as a channel change, a drift between audio and video presentation time stamps in an audio/video stream is determined. The thus determined drift serves to compute a duration of a slow video motion start sequence with a given slow video rate, so that video can be shown early without yet being synchronized with audio. The slow video motion start enables the audio to catch up with the video and allows to ensure a synchronization of audio with video after the duration of the slow video motion start sequence, where after video and audio are synchronized and evolve normally. The present principles use a single decoder clock that is fed to the audio and video decoders, the decoder clock fed to the video decoder being offset with a decreasing value during the period of slow video motion.

Method for decoding an audio/video stream and corresponding device

A method for managing cache memory in a user device is disclosed. The method comprises stagewise excluding adding data to the cache memory as cache memory fill level increases, the stagewise excluding comprising determining, for each successive stage of cache memory fill level, exclusion of the data from being added to the cache memory according to rules of exclusion of adding of data to the cache memory that are increasingly restrictive.

Method of optimization of cache memory management and corresponding apparatus

A method, arrangement and device comprising the arrangement enabling to determine if audio data is present in a digital audio/video stream. If presence of audio data is determined and audio is muted and/or below a determined level, a visual indication is generated which indicates the presence of audio data in the digital audio/video stream.

Method for audio detection and corresponding device

The invention proposes a method of display of a user interface, that comprises the following steps: a step of display in foreground of a first user interface generated from stored display elements, comprising a first set of display elements providing access to first services, a reception step of a second set of display elements giving access to second services, and a display step of a second user interface in foreground, replacing the first user interface. The invention also relates to a method of transmission of a set of display elements giving access to services, that comprises the following steps: a transmission step of a first set of display elements, giving access to services, and a transmission step of a second set of display elements, giving access to services, and destined to be stored.

Method of display of a user interface and corresponding transmission method

The present invention generally relates to digital communications, and more particularly, to a technique for processing data in a digital communication device so as to reduce channel change times. To this effect, the invention comprises a specific sequencing and arrangement of operations that are required to be executed in the digital communication device during a channel change.

Method of digital audio/video channel change and corresponding apparatus

A digital decoder for television receiver, comprises an input (E) for receiving a digital audio/video signal (SAV), means for demodulating and decoding the input signal into an output signal intended for the television receiver, and a first buffer memory () into which the input signal is diverted after demodulation (SD) when the decoder is placed in a so-called 'live' mode of operation. In a so-called 'playback' mode of operation, the signal recorded in the first buffer memory constitutes the output signal. This decoder comprises a second buffer memory () into which the demodulated input signal (SD) is diverted when the decoder is placed in the &#x201c;playback&#x201d; mode, the signal recorded in the second buffer memory () constituting the output signal when the decoder is switched from the &#x201c;playback&#x201d; mode to another so-called &#x201c;return to live&#x201d; mode of operation. In the &#x201c;return to live&#x201d; mode, the user views at high speed the video portion recorded in the second buffer memory before the decoder switches back to the &#x201c;live&#x201d; mode.

Digital decoder having a so-called 'playback' mode of operation and comprising two buffer memories

The present invention relates to a method used to indicate a service interruption source, in a client device of said service comprising an interface to a first network, said device being connected to a remote server by means of a gateway to which said device is connected by means of said first network; comprising the steps for starting up a downloading session from said remote server of a content, the end of the session requiring an acknowledgement from the user, detecting the connection loss between the device and the gateway, detecting the connection recovery between the device and the gateway, sending information (S) to the server indicating the device disconnection period.

Method for indicating a service interruption source

A digital decoder for television receiver, comprises an input (E) for receiving a digital audio/video signal (SAV), means for demodulating and decoding the input signal into an output signal intended for the television receiver, and a first buffer memory () into which the input signal is diverted after demodulation (SO) when the decoder is placed in a so-called 'live' mode of operation. In a so-called 'replay' mode of operation, the signal recorded in the first buffer memory constitutes the output signal. This decoder comprises a second buffer memory () into which the demodulated input signal (SO) is diverted when the decoder is placed in the &#x201c;replay&#x201d; mode, the signal recorded in the second buffer memory () constituting the output signal when the decoder is switched from the &#x201c;replay&#x201d; mode to another so-called &#x201c;return to live&#x201d; mode of operation. In the &#x201c;return to live&#x201d; mode, the user views at high speed the video portion recorded in the second buffer memory before the decoder switches back to the &#x201c;live&#x201d; mode.

Method for receiving audio and/or video services and an automatic selection step of audio or audio/video services. In order to optimise access to varied services, the method comprises:

Method for selecting an audio and/or video service received

The invention relates to a method of sending commands to a VOD server, e.g. using RTSP, which is local to the client, said commands comprising a reference to the relative current position. The current relative position is maintained by the receiver on the basis of PTS received in the MPEG stream, without sending a request to the server or relying on the existence of a descriptor in the stream that can be used to deal with jumps in PTS included in the stream.

Method of sending a command to a digital data flow server and apparatus used to implement said method

The present invention relates to the domain of reception and transmission of data streams, for example audio and video. More specifically, the invention relates to the optional use of an error correction stream associated with a data stream.

Method for receiving data streams and corresponding method for transmission

The present invention relates to a method for recovering a downloading section that has been interrupted, in a device comprising an interface with a network enabling access to a remote server and means for implementing a downloading session with the said server, comprising the steps for starting up a downloading session of a content from the remote server, by means of more than one signalling channel with at least the said server, detecting a premature interruption of the downloading session, verifying the availability of all the channels, as long as one of the channels is unavailable, the session is not recovered and when all the channels are again available, the session is recovered.
