A method of displaying characters is adapted to a displaying device. First, the displaying device receives and analyzes a frame to obtain subtitle data including a first character. Then, the subtitle data is analyzed to obtain at least one first location of the first character on the frame. Finally, the first character is displayed at the at least one first location in a first time period.

Method and device of displaying characters

A data processing apparatus including a register bank, a shadow register and an arithmetic operation unit. The register bank includes a number of registers respectively for storing a number of operands wherein the registers are n-bit registers, and n is a nature number. The shadow register stores a first backup operand for making a backup of a first operand, which is stored in a first one of the registers in response to first control signal. The arithmetic operation unit performs at least an arithmetic operation on the operands to obtain operational data, and stores the operational data in the first register in response to an arithmetic operation command.

Data processing apparatus with shadow register and method thereof

A method for determining a sound standard for an input sound signal includes the following steps. Firstly, the input sound signal is filtered to obtain a first filtered signal corresponding to a first frequency and a second filtered signal corresponding to a second frequency. Next, the first filtered signal is frequency-demodulated to obtain a first demodulated filtered signal, and whether the input sound signal contains a FM analog component corresponding to the first frequency is determined accordingly. Next, the second filtered signal is decoded according to a digital sound standard to obtain a bit stream. Then, the bit steam is interpreted according to the digital sound standard, and whether the input sound contains a digital component corresponding to the digital sound standard is determined accordingly. Then, whether the input sound signal matches one of known sound standards is determined based on the determined results above.

One embodiment of the present invention sets forth a method of generating a packet identifier table that comprises reading a packet identifier value from a received transport stream packet, identifying a type of data contained in the received transport stream packet, and generating a table with mapping information between the packet identifier value and the identified type of data.

Method and system for generating a packet identifier table from a received transport stream

A method for receiving a station signal is provided. First, a radio frequency signal is received and converted to a first IF signal. Next, the first IF signal is demodulated to a baseband signal and a demodulation signal is obtained, the demodulation signal being a result of differentiating a phase of the baseband signal. Then a determination as to whether a DC level of the demodulation signal has an S-curve characteristic at a specific frequency is made according to the demodulation signal. If so, the specific frequency is determined as a first station frequency, a first station signal is obtained from the radio frequency signal according to the first station frequency.
