Abstract: According to an embodiment, an encoding device includes an encoder. The encoder is configured to generate a video stream. The video stream includes at least a first image group including a plurality of images encoded at a first bit rate and a second image group including a plurality of images. The first image group includes an intra-coded image. The plurality of images of the second image group are associated with the intra-coded image serving as a reference image to decode an inter-coded image, and are encoded at a second bit rate different from the first bit rate and having reproduction timing in synchronization with the plurality of images of the first image group.

Abstract: A portable motion recorder (10) determines an amount of energy necessary for the daily basal metabolism of a user and the amount of energy consumed by the user for metabolism for living activities on the basis of measured data measured by a pedometer included therein and user's basic personal data entered by operating an input unit (12). Data provided by the portable motion recorder (10) is displayed on a display unit (16). The portable motion recorder (10) receives measured data measured by exercise machines (20, 30, 40) from the same. Comprehensive evaluation of energy consumed by the user is made on the basis of energy necessary for user's daily basal metabolism, energy consumed by the user for metabolism for living activities, and energy consumed by exercise using the exercise machines (20, 30, 40). The result of comprehensive evaluation as information about the user's health maintenance condition is displayed on the display unit (16).
