Abstract: A method for conflict recognition on DiSEqC protocol, the method comprising the steps of generating a command to be sent to a DiSEqC device; requesting a tuner to send the command to the DiSEqC device; the method further comprises: after the step of generating the command and prior to the step of requesting a tuner to send the command, executing the following steps: sending a ODU_PowerOFF DiSEqC command from the tuner to the DiSEqC device; stopping the tuner in case the ODU_PowerOFF DiSEqC command results in unlocking the tuner; sending a “ODU_Channel_change” DiSEqC command from the tuner in order to request to retune the DiSEqC device to new parameters; assuming lack of conflict in case the tuner is locked according to the requested parameters.

Abstract: The present invention relates to a memory card (201) for a digital television decoder, which has a memory block (202) with a separate data memory area (205). The separate data memory area (205) can have the size from ten megabytes to a few gigabytes and can be used for storing audio/video data, audio data or application programs for the digital television decoder. The card also comprises a conditional access circuit (207) for descrambling of data stored in the separate data memory area (205), and a controller (206) for controlling the data flow inside the card. The controller (206) allows replay of data from the separate data memory when the conditions for replay of data, stored separately for each data file, are met.
