Portable video programs

Abstract: A method consistent with certain embodiments provides portable delivery of television programs to a portable wireless device (PWD) involves using the PWD to capture a sample of a program being played by a television; transmitting attributes of the captured sample to a service provider so that the service provider can identify the program being played by the television; and receiving the television program at the PWD from the service provider via a wireless transmission. This abstract is not to be considered limiting, since other embodiments deviate from the features described in this abstract.

Power transmission device, power transmission method, program, power receiving device and power transfer system

Abstract: There is provided a power transmission device including a communication part that performs communication with an external power transmission device that transmits power, a power transmission part that transmits power to a power receiving device that receives the transmitted power in a non-contact manner, a determination part that determines whether power can be transmitted, based on external power transmission information received by the communication part indicating a start of power transmission by the external power transmission device, and a power transmission control part that controls the power transmission part to selectively transmit power based on a determination result from the determination part.

Network distribution and management of interactive video and multi-media containers

Abstract: Interactive interfaces to video information provide a displayed view of a quasi-object called a root image. The root image consists of a plurality of basic frames selected from the video information, arranged such that their respective x and y directions are aligned with the x and y directions in the root image and the z direction in the root image corresponds to time, such that base frames are spaced apart in the z direction of the root image in accordance with their time separation. The displayed view of the root image changes in accordance with a designated viewing position, as if the root image were a three-dimensional object. The user can manipulate the displayed image by designating different viewing positions, selecting portions of the video information for playback and by special effects, such as cutting open the quasi-object for a better view. A toolkit permits interface designers to design such interfaces, notably so as to control the types of interaction which will be possible between the interface and an end user. Implementations of the interfaces including editors and viewers are also disclosed.

Midori: A Block Cipher for Low Energy

Abstract: In the past few years, lightweight cryptography has become a popular research discipline with a number of ciphers and hash functions proposed. The designers' focus has been predominantly to minimize the hardware area, while other goals such as low latency have been addressed rather recently only. However, the optimization goal of low energy for block cipher design has not been explicitly addressed so far. At the same time, it is a crucial measure of goodness for an algorithm. Indeed, a cipher optimized with respect to energy has wide applications, especially in constrained environments running on a tight power/energy budget such as medical implants. This paper presents the block cipher Midorii¾?The name of the cipher is the Japanese translation for the word Green. that is optimized with respect to the energy consumed by the circuit per bt in encryption or decryption operation. We deliberate on the design choices that lead to low energy consumption in an electrical circuit, and try to optimize each component of the circuit as well as its entire architecture for energy. An added motivation is to make both encryption and decryption functionalities available by small tweak in the circuit that would not incur significant area or energy overheads. We propose two energy-efficient block ciphers Midori128i¾?and Midori64i¾?with block sizes equal to 128 and 64 bits respectively. These ciphers have the added property that a circuit that provides both the functionalities of encryption and decryption can be designed with very little overhead in terms of area and energy. We compare our results with other ciphers with similar characteristics: it was found that the energy consumptions ofi¾?Midori64i¾? and Midori128i¾? are by far better when compared ciphers like PRINCE and NOEKEON.
