摘要:
The timing synchronization module includes a phase locked loop (PLL) and a synchronization processing unit. The PLL receives an output-end clock signal. When the PLL receives the output-end clock signal for the first time, the PLL generates a reception-end clock signal according to the output-end clock signal. The synchronization processing unit receives a procedure clock signal and the reception-end clock signal. The output-end clock signal has M clocks after the reception-end clock signal is generated, while the reception-end clock signal has N clocks as generated. When the difference value of M and N is larger than a preset value, the synchronization processing unit removes the media signal corresponding to the procedure clock signal and generates the reception-end clock signal again. When the difference value is smaller than the preset value, the synchronization processing unit controls media signal playing according to the reception-end clock signal and the procedure clock signal.

An image saving method and a computer-readable medium thereof. First, an image with a first image resolution is saved to a memory unit. Next, a parameter corresponding to the image is requested to be inputted. Then, a saving status of the memory unit is judged. Finally, when the saving status of the memory unit approaches a threshold value, the image with the first image resolution is automatically downsized to a downsized image with a second image resolution according to the parameter.

The connecting port is used for connecting to the first display, the signal processing unit is used for generating a first video signal, the microcontroller is used for generating a control signal and transmitting the control signal to the signal processing unit for generating a second video signal, and the switching unit is used for triggering the signal processing unit to selectively transmit the first video signal and the second video signal to the connecting port and the second display.
摘要:
A method for adaptive encoding a video signal and an apparatus therefor. A predetermined frame resolution and quantizer step size are provided. A first input frame of the video signal is subsequently sampled and encoded based on the predetermined frame resolution and the quantizer step size, respectively. If the size of the encoded first input frame is substantially greater than a first predetermined encoding size, the predetermined frame resolution is reduced and the first input frame is sampled accordingly. The method further includes reducing the predetermined frame resolution if the time period spent in encoding is substantially greater than a predetermined encoding time. The method reduces packet loss or delay during transfer at constant bit rate.

An apparatus for processing an input file is provided. The apparatus includes a transforming module, a combining module, and a transmitting module. The transforming module transforms the input file into an output file in a VOB (video object) format. The combining module first generates an information file corresponding to the output file and then combines the output file with the information file to generate a combined file. The transmitting module is used for transmitting the combined file generated by the combining module.

A display system controlled based on users' behavior is provided. The display system is used for displaying an image. The display system includes a timer, an analyzing module, and a projecting apparatus. The timer is used for counting a current time. The analyzing module generates at least one standby time period based on a set of predetermined information, wherein the set of predetermined information relates to users' behavior. The projecting apparatus for projecting the image is selectively in a projecting mode, a standby mode and a turning-off mode. When the current time is in the at least one standby time period, the projecting apparatus is selectively in the projecting mode and the standby mode.

A method for message compression comprises receiving a first text message, acquiring at least one frequent character combination in the first text message, calculating frequencies for the frequent character combination and characters occurring in the first text message, generating multiple representative codes respectively for the frequent character combination and characters, and encoding the first text message to a second text message.
摘要:
A cooler is applied in an electronic apparatus. The electronic apparatus comprises a shell. The shell comprises a cooling opening. The cooler comprises a case and a cooling fan. The case has a connecting opening. The four walls around the connecting opening comprise at least one joint for jointing the cooling opening in a jointing direction. The cooling fan is located in one side of the walls and eliminates the heat in the shell in a cooling direction. The cooling direction is vertical to the jointing direction.
