摘要:
An apparatus and method for managing a preference channel are provided which can reduce a delay time when a channel change is made between preference channels, by storing a preference channel directly selected by a mobile terminal user in a mobile broadcast system. A mobile terminal receives and demultiplexes multiplexed logical channels on which data streams are transmitted from a service provider through a communication network. Preference channels of the demultiplexed logical channels are dynamically allocated to decoding buffers using stored information. A decoding time at which data of the decoding buffers is accessed and decoded is computed using reference information. A decoding operation is performed at the computed decoding time, and decoded channel-by-channel elementary streams are stored in a memory. The decoded channel-by-channel elementary streams stored in the memory are displayed on a screen of the mobile terminal.

A sensing method of an image sensor. The image sensor includes: a light receiving device; a signal conversion unit including a transfer transistor having a plurality of transfer gates and for converting photocharges generated by the light receiving device into a voltage to output the voltage; and a sensing control unit for generating at least two reset signals and/or at least two transfer signals applied to the transfer gates of the transfer transistor during a one-time photosensing cycle. The image sensor is obtained by changing the structure and driving method of a transfer transistor of a typical 4-transistor CMOS image sensor and employs a deep depletion operation and a multiple reset operation, thereby reducing an image lag and increasing the well capacity of the light receiving device.

Provided is a 4-transistor CMOS image in which a driving condition or a pixel structure is changed so that a transfer transistor in a pixel operates in a pinch-off condition during reset and transfer operations in order to reduce dark current and fixed-pattern noise caused by a change in an operation condition of the transfer transistor and inter-pixel characteristic discrepancy. The image sensor includes a photosensitive pixel including a transfer transistor for transferring photon-induced charges created in a photodiode; and a voltage control unit for controlling a turn-on voltage applied to a gate of the transfer transistor to be lower than a floating diffusion node voltage plus the threshold voltage of the transfer transistor during a partial or entire section of a turn-on section of the transfer transistor such that the transfer transistor operates in a pseudo pinch-off mode.

摘要:
Provided are an image sensor and a driving circuit of a transfer transistor for charge transfer in a light receiving unit realized in the image sensor, in which a pixel is insufficiently reset to be always operated in a pseudo pinch-off condition, unlike a conventional reset method in which a pixel structure of a 4-transistor CMOS image sensor or its analogue has to be depleted, thereby reducing a reset voltage of a photodiode and reducing a dark current and fixed pattern noise generated due to discordance of characteristics between pixels.The image sensor includes a conversion module for lowering a turn-on voltage of a signal or changing its waveform, a module for providing a negative voltage if necessary, and at least one module for limiting the slope of an output signal, and the characteristics of the image sensor are improved by operating the transfer transistor in the pseudo pinch-off mode.
摘要:
Provided is a light sensing pixel including an image sensor. In a general four-transistor Complementary Metal-Oxide Semiconductor (CMOS) image sensor, unlike a conventional structure, a transfer transistor in a pixel includes a depletion region separated from a channel that is not influenced by a turn-on voltage of the transfer transistor regardless of a driving voltage or a driving method when a photodiode is reset and transferred. As a result, dark current or fixed pattern noise, caused by a change in operating condition of the transfer transistor and inconsistent characteristics between the pixels, is reduced.The image sensor includes a light sensing pixel that includes the transfer transistor for transferring a light-induced charge generated by the photodiode. The light sensing pixel, to dispose the depletion region between the channel of the transfer transistor and a diffusion node, i.e., to operate in the similar pinch-off state, may have a structure in which an insulating layer of the diffusion node side is thicker than a gate insulating layer adjacent to the photodiode in the transfer transistor. That is, the insulating layer of the transfer transistor has steps or a gradual change in thickness. Also, the light sensing pixel may have a structure in which pocket/halo implant using electrically the same material as a doping material of a substrate is performed between the channel of the transfer transistor and the diffusion node.

摘要:
A method, apparatus and system are provided for controlling a scene structure of a mobile terminal for receiving and displaying data streams in a mobile broadcast system. When logical channels are multiplexed into one physical channel, the multiplexed channels are sequentially decoded and are displayed on an image. A channel circulation scene alternately displays the channels on one image in designated order. In a combination scene structure, a new node is added to a conventional Lightweight Application Scene Representation (LASeR) technology. To compose a scene, fields for time information and scene transition effect are provided. A delay time due to a channel change is reduced. A multi-channel image is effectively provided to address a problem when a user retrieves service content while directly switching a channel. The terminal dynamically composes the multi-channel image using stream source node information from a service provider without an additional mosaic channel.
