摘要:
There is provided a transmission system which realizes more flexible resource allocation. A resource management means 12, upon receipt of a resource allocation request including a minimum bandwidth and a maximum bandwidth, reduces allocated resources stored in an allocated-resource request table 13 to the corresponding minimum bandwidths. As such, the request is accepted with higher probability. When releasing an allocated resource, the resource management means 12 increases the allocated-resources of the allocated-resource requests to bandwidths within a range of the corresponding maximum bandwidths. Accordingly, the resources are utilized more effectively. When releasing the resource, the resource management means 12 notifies, by broadcast, all the communication apparatuses that free resources are increased. Thus, for the communication apparatus whose request has been rejected, the resource is allocatable.
摘要:
First through third light reception elements 111–113 receive infrared data D from an operation input transmission section 2, and output the received data to an operation input permission determination section 12a. The operation input permission determination section 12a distinguishes among the first through third infrared light reception elements 111–113, thereby determining in which space an operation input has been performed, and analyzes the description of the operation input, thereby determining whether to accept the operation input. A calculation processing section 13a performs various processes based on the description of the operation input from the operation input permission determination section 12a, a processing result of a position detection section 17, and map data stored in a map data storage section 16. A drawing processing section 14a performs a process of outputting a processing result of the calculation processing section 13a to first and second displays 3 and 4.

A display system (100) is provided which includes two display devices (101a and 101b); a coupling section (102) for coupling the two display devices such that one display device can be displaced relative to the other display device; a detection section (111-114) for detecting a value by which a position of the one display device relative to the other display device can be identified; and a display control section (115) for generating an image to be displayed on each of the one and the other display devices, based on the position detected by the detection section. The one and the other display devices display their respective images generated by the display control section.
摘要:
A control device determines whether an image generated by merging several concurrently picked-up images has consistent image quality on a display device. If determined No, image quality parameters set in each image pickup device are so controlled as to make the image quality of the merged image consistent. Therefore, the merged image can assuredly have consistent image quality. Further, a signal processing device detects, based on positions of nodes and attributes of cameras, a connection indicating which node is connected to which camera and with what attribute. The signal processing device in advance stores every detectable connection and a plurality of image processing programs corresponding to each connection, and selects and carries out one of the image processing programs corresponding to the detected connection.
摘要:
A first initialization pattern signal is a signal in which a maximum signal level and a minimum signal level appear alternately, and a second initialization pattern signal is a signal in which all signal levels appear in a predetermined arrangement. In a ring-shaped network including plural stages of data transmission apparatuses (100), a transmission unit (110) of each data transmission apparatus outputs the first initialization pattern signal successively to a next-stage data transmission apparatus at turn-on of power or immediately after reset, and a reception unit (120) establishes clock synchronization on the basis of the first initialization pattern signal received. When synchronization is established in all of the data transmission apparatuses, the transmission unit (110) outputs the second initialization pattern signal successively to the next-stage data transmission apparatus, and the reception unit (120) sets evaluation levels for the respective signal levels on the basis of the received second initialization pattern signal, and transmission/reception of data is started when evaluation levels are set in all of the data transmission apparatuses.

摘要:
A moving picture compressed signal changeover apparatus changes over from a first moving picture compressed signal containing intra-frame coded frames, forward prediction coded frames and bidirectional prediction coded frames to a second moving picture compressed signal containing intra-frame coded frames, forward prediction coded frames and bidirectional prediction coded frames such that a frame of the first moving picture compressed signal occurring just before an intra-frame coded frame or a forward prediction coded frame of the first moving picture compressed signal is connected to an intra-frame coded frame of the second moving picture compressed signal. A predetermined signal which is different from the first and second moving picture compressed signals may be inserted between the connected frames of the first and second moving picture compressed signals. Alternatively, at least one of the first and second moving picture compressed signals may be delayed so as to adjust a connecting timing.
