An importance level determination unit receives: input from a camera of frames of moving images taken; input from a switch connected to a server which is operated manually by hand; and voice input from a microphone. Based on these it determines the importance level of each image frame. An encoder compresses and encodes the image frames obtained by the camera and generates moving picture streams. A packetizer packetizes the moving picture streams and gives them to a tag attachment unit. The tag attachment unit attaches the importance level set for the respective image frames to packet headers of the moving picture streams as a priority tag. A transmission unit transmits packets with a priority tag to a network which includes a router with a packet priority control function.

Disclosed is a pneumatic tire including a straight main groove and two wave-shaped main grooves arranged in the center area of a tread, and diagonal grooves arranged in each shoulder area ranging from each wave-shaped main groove to the outer side of the tire, and extending obliquely outward from the wave-shaped main groove to a direction reverse to the tire rotational direction, the rotational direction being specified for the tire. Each diagonal groove is formed to have a convex protruding toward the outer side of the tire, and the extending end portion of the diagonal groove terminates in the shoulder area. Thus, each shoulder area is provided with a non-block pattern in which a land section continues in the tire circumferential direction. Thereby, the pneumatic tire has increased driving stability and uneven wear resistance while substantially maintaining good drainage performance and noise performance against columnar resonance.

A tread surface the tire rotational direction of which is specified in one direction has a center region and shoulder regions on both sides of the center region. Blocks are defined in at least one of the shoulder regions by at least one first circumferential groove which extends in a circumferential direction of the tire, and first lateral grooves which extend in a widthwise direction of the tire and are disposed at predetermined intervals in the tire circumferential direction. Each block includes a tire rotational direction side groove wall surface having an inclination angle α, and a tire reverse rotation direction side groove wall surface having an inclination angle β, and the inclination angle β is greater than the inclination angle α. Each block has a tire rotational direction side edge portion which is chamfered.

Disclosed is a pneumatic radial tire allowed to compatibly enhance its high-speed durability and to reduce road noise. In the tire, a plurality of belt layers 3 are arranged on an outer periphery of a carcass layer 2, and a belt reinforcement layer 4, which is formed of reinforcing cords spirally wound up substantially in a circumferential direction, is arranged in the vicinity of the belt layers. While an overhanging length L, by which the belt reinforcement layer 4 overhangs from an end of a maximum-width portion of the belt layers, is set in a range of 5 to 20 mm, an intermediate elongation of the reinforcing cords of the belt reinforcement layer 4 under a load of 67 N is set in a range of 1.5 to 5.5%.
