In one embodiment, the method of multicast includes assigning a pilot sequence to each program from among a plurality of programs such that each program has a unique pilot sequence. Digital images may be processed by first creating a histogram that identifies the intensity of components of the digital image. Such structured remote control unit can offer an electronic program guide service and other services, introducing them not on the TV display but on the display of the unit on hand. Next, the polysaccharide material is mixed with an ionic liquid to form a polysaccharide solution. The movable unit is configured to move between a near position and a far position where is away from the near position with respect to the main body. Responsibilities for configuring, provisioning and forwarding over a transport LAN segment are divided between layer 2 and 3 service provider edge devices, where the layer 3 edge device handles discovery and tunneling responsibilities, the layer 2 edge device handles learning and flooding responsibilities, and information can be exchanged between the layer 2 and 3 edge devices.
