摘要:
An HDTV signal (dot density: 2N dots/line) is converted into a luminance signal and a line sequential color signal, and the resulting signals are both subjected to vertical interpolation and vertical filtering to derive a sequential scanning luminance signal and a sequential scanning color signal. The resulting sequential scanning luminance signal and sequential scanning color signal are subjected to frame thinning to reduce the frequency thereof to a half. Then, subsampling is performed to reduce the dot density to N dots/line. Next, dot rearranging for distributing adjacent dots to adjacent lines is performed to double the number of frames, whereby the dot density of each frame is reduced to N/2 dots/line. These consequently derived frames are encoded for recording. In this manner, the frequency bandwidth required to a recording medium for recording HDTV signals can be reduced.

A video signal recording and reproducing system enables recording and reproducing of a video signal with high quality. The system includes a recording system for recording the video signal on a record medium by means of a median filter and a reproducing system for reproducing the video signal from the record medium. The recording system separates a brightness signal and a color signal from an interlaced scanning signal. The recording system divides picture elements of each line into two phases by sorting the elements such that an element is put into one phase and the next element into the other. The recording system then carries out two-dimensional subsampling to the brightness signal and the color signal to reduce the amount of data. Then, the recording system compresses and time-division multiplexes the brightness signal and the color signal to provide a video signal to be recorded onto a record medium. The reproducing system separates the brightness signal and the color signal from a video signal read out from the record medium, and then interpolates picture elements into the two signals to obtain sequential scanning RGB signals for 525 scanning lines.

There are provided a versatile power meter, a power measurement method, a program and a recording medium. The power meter includes a first measurement unit 7 that measures a force applied to a first pedal B322 and calculates predetermined first information (power and/or torque) on the first pedal B322, and a second measurement unit 6 that measures a force applied to a second pedal B321 and calculate second information (power and/or torque) on the second pedal B321, which is the same kind of the first information. The first measurement unit 7 transmits first information data indicating the first information to the second measurement unit 6, and the second measurement unit 6 adds the first information to the second measurement information and transmits an added value data indicating an added vale obtained by adding the first information to the second information.

An apparatus is provided that warns a vehicle of a harsh braking-applied vehicle based on information sent from the harsh braking-applied vehicle. The apparatus includes a reception device, a position detection device, a forward side vehicle judgment device, and a warning device. The reception device receives the information indicating that harsh braking has been applied to the harsh braking-applied vehicle and information indicating a position of the harsh braking-applied vehicle. The position detection device detects a position of the vehicle to be warned, and the forward side vehicle judgment device determines if the harsh braking-applied vehicle is in front of the vehicle to be warned based on the positions of the harsh braking-applied vehicle and the vehicle to be warned. The warning device warns the vehicle to be warned when the harsh braking-applied vehicle is in front of the vehicle to be warned.
