The present invention encompasses methods and systems of transcoding frame-based video to frame free video is provided. The method comprises receiving a frame-based video stream, upconverting the received frame-based video stream to produce an upconverted frame-based video stream at a higher frame rate than the received frame-based video stream, and modulating the upconverted frame-based video stream using discrete time sigma delta modulation to produce a frame free video stream. In addition, complimentary methods and systems are disclosed for transcoding frame free video to frame-based video.

An access point is configured to communicate with a wireless client device over a plurality of wireless communication channels. The wireless client device has an active operation state and a standby operation state. The access point detects a property of each of a first wireless communication channel and a second wireless communication channel, and applies a policy to the detected properties to select one of the first wireless communication channel and the second wireless communication channel. While the wireless client device is in the active operation state, the access point steers the client device to communicate with the access point over the selected channel.

There is provided an image processing apparatus and method allowing suppression of a decrease in coding efficiency. Coded data obtained by coding a captured image captured by a moving body with an image capturing section is transcoded on the basis of positional information indicating a position where the captured image has been generated. For example, the positional information includes at least one of GPS information indicating the position of the moving body or IMU information indicating movement of the moving body, and captured images are coded in frame images of a moving image on the basis of the information. For example, the present disclosure can be applied to an image processing apparatus, an image coding apparatus, a communication apparatus, an information processing apparatus, an image capturing apparatus, or the like.
