摘要： A system and method for switching between a plurality of audio settings is disclosed. The system includes: an audio processing system for receiving audio data from an audio data source, including: a central processing unit (CPU) for storing a plurality of volume settings; and a toggle switch for toggling between the plurality of volume settings to select a volume setting. The audio system also includes a displaying device for displaying audio data received from the audio processing system according to the selected volume setting. The method includes: assigning a first volume setting for an audio data and saving the first volume setting; assigning a second volume setting for the audio data and saving the second volume setting; and toggling between the first volume setting and the second volume setting so the audio data is played at either the first volume setting or the second volume setting.

摘要： A personal video recorder (PVR) system includes a processing unit, a system memory coupled to the processing unit by a system memory bus, and an insertion module being coupled to the processing unit for inserting a packet into a PVR bit stream according to packet information. During a packet insertion operation, the processing unit is for reading data from the system memory, processing the data to generate the packet insertion information, and directly transferring the packet insertion information to the insertion module. By directly transferring the packet insertion information generated by the processing unit to the insertion module, memory bandwidth requirements of the system memory are reduced, and data access of the system memory is improved.

摘要： A method of processing a transport stream having a plurality of packets to output a protected transport stream includes providing a set of secret keys having a predetermined number of secret keys; generating a key indication value; selecting a secret key from the set of secret keys according to the key indication value to form a selected secret key; generating an encrypted packet based on the selected secret key and a packet in the transport stream by: encrypting the payload of the packet according to the selected secret key, and storing the key indication value in the sync field; and generating the protected transport stream based on the encrypted packet. Where each packet comprising a packet header and a payload, the packet header comprising a sync field, and the sync field carrying a preset sync pattern.

摘要： A demodulated signal in a digital media system includes an audio bitstream that is transmitted to an audio decoder and program information that includes program content category. A plurality of customizable sets of data that identify desired modifications to audio characteristics are respectively associated with specific program content categories. Program content category information is obtained from the received program information and the audio modification data set associated with that program content category is applied to the decoded audio signal before output.
