Abstract: According to one embodiment, a video display apparatus includes a display screen generator, a waiting time determination module, and a display. The display screen generator generates a first screen and a second screen from predetermined information. The waiting time determination module determines an estimated waiting time. The display compares the estimated waiting time with a reference time, displays the first screen when the estimated waiting time is shorter than the reference time, and displays the second screen when the estimated waiting time is longer than the reference time.

Abstract: A biological information processing apparatus obtains a pulse wave signal indicating a pulse wave of a subject, and acceleration measured according to body motion of the subject and calculates an amount of body motion of the subject using the acceleration. By using at least one of the body motion amount and the acceleration, the apparatus approximates a heart rate of the subject and sets a parameter to be used for detection of a pulse interval using the heart rate. Then, the apparatus detects each pulse interval using a pulse waveform indicated by the pulse wave signal and the parameter.
