摘要： Techniques for a personalized Bluetooth headset and a voice interaction control method thereof are described. According to one aspect of the present invention, the Bluetooth headset is configured to create and maintain a voice-based table. Each item in the table includes a phone number paired with a set of audio data (e.g., a voice or a predefined audio), where the audio data is created by a user. When a paired mobile device receives a call, the table is searched per the caller number. A corresponding audio is played back first when an item is located in the table. As such a user of the Bluetooth headset knows who is calling and determines whether the call shall be answered or not.

摘要： Techniques pertaining to the transmission of digital data via a conventional transmission medium (e.g., a coaxial cable for TV) specifically for analog composite video signals are disclosed. To retrofit in an existing system not designed for transmitting digital signals or data, the techniques are provided to convert the data into an analog signal that is transmitted over a coaxial cable, where the analog signal, when received, is decomposed to recover the data. According to one aspect of the present invention, videos in high quality (e.g. high definition or HD format) from HD cameras are used in the conventional surveillance system, where the transmission medium for the analogy videos is already installed.

摘要： Techniques for controlling a personalized Bluetooth device (e.g., headset) and a voice interaction control method thereof are described. According to one aspect of the present invention, the Bluetooth device is caused to maintain a voice contact list. Each item in the voice contact list corresponds to a phone number associated with a set of audio data (e.g., a voice or a predefined audio). Instead of dialing a phone number on a calling device (e.g., a cellular phone) being paired with the Bluetooth device, a user can speak to the Bluetooth device that is caused to search a corresponding phone number in the voice contact list. The number is then sent to the calling device to make a call.
