A mobile telephone receives, constructs and displays an image from a server over a mobile telephone network. The server determines the parameters for data transfer from the server to the mobile telephone, the capabilities of the mobile telephone, transfer task requirements, and apportions the processing between the server and the mobile telephone for each of a plurality of elements in each image, thereby to meet the task requirement, which can include being within a predetermined time for task completion, or being the fastest means for task completion. Parameters for data transfer from server to telephone include server transmission bandwidth, phone reception bandwidth, data channel bandwidth, transmission protocol, and channel accessibility. Phone capabilities include the data processing speed, the available memory, display size, and the data processing software available; Task requirements include the maximum transmission time and the minimum display resolution of the image.

A method of decoding video, comprising: receiving an encoded bit stream representing frames of video, each of the frames comprising blocks of pixels; for a current block to be decoded, obtaining a vanishing point from the encoded bit stream and calculating pixel values of the current block to be decoded by performing intra-prediction based on a prediction line originating in the vanishing point; and providing decoded video based on the calculated pixel values. A method of encoding video, an encoder, and a decoder are also disclosed.

A device, method and program may properly perform gamut conversion of content and be applied to a gamut conversion device. A restoration conversion state confirming unit performs confirmation such as gamut conversion state of image data read out from an optical disc and the existence or not of restoration metadata. An information exchange unit communicates with an output device via a communication unit and performs information exchange such as the existence or not of restoration processing functionality and gamut conversion functionality and the like. A determining unit determines whether or not restoration processing is performed with a playing device based on information obtained by the restoration conversion state confirming unit and the information exchange unit. Similarly, the determining unit determines whether or not to perform gamut conversion processing with the playing device based on information obtained by the restoration conversion state confirming unit and the information exchange unit.

An image forming apparatus includes: a key receiving a copy-start instruction and an input of a number of copies depending on a number of times that the key is operated; a scanner reading an image of a document and generating image data relating to the image; a printer recording the image on a sheet; a memory; and a controller. The controller controls the scanner and the printer to execute, depending on the number of times that the key is operated: (1) direct copy of storing parts of the image data relating to the image successively in the memory, and of reading the parts of the image data from the memory to record the image data on the sheet, or (2) memory copy of storing entirety of the image data in the memory, and of successively reading parts of the stored image data to record the image on the sheet.

An information processing apparatus includes a wireless interface configured to perform communication with an image forming apparatus, and at least one controller configured to function as a unit configured to acquire device information of the image forming apparatus from the image forming apparatus through the wireless interface, and a unit configured to selectively accept one of a first instruction to transmit the acquired device information to an external destination and a second instruction not to transmit the acquired device information to the external destination. The controller also functions as a unit configured to transmit, in a state where the first instruction has been accepted, the acquired device information to the external destination, and hold, in a state where the second instruction has been accepted, the acquired device information without transmitting the acquired device information to the external destination.
