The primary issue regarding the transmission of digital video to automobiles is limited bandwidth. To help combat bandwidth issues, compression techniques have been developed to reduce the high bit rate required for transmission and storage. However, methods for improving the perceived quality of digital imagery, particularly at low bit rates, are critical. The present invention discloses a technique that will improve the perceived quality of digital imagery to the viewer by using selective post-processing of decompressed digital video. The human visual system (HVS) is very sensitive to human eyes and faces. Regions of interest (ROI), such as human eyes or faces, are selectively post-processed in appropriate video frames prior to being displayed to the viewer. If a subject's eyes are sharp, the viewer will perceive good image quality, despite poor rendition elsewhere. If the subject's eyes are blurry or poorly rendered, the frame will appear poor to the viewer, despite sharpness elsewhere.

As the number of contents which a user can access (TV programs, images stored on HDD or Internet news) is increasing, the contents a viewer wishes to view is becoming increasingly diverse, and consequently the question of how to view these contents efficiently is now a major problem. In other words, this huge volume of broadcast content also contains information which the user does not require, and it is difficult to efficiently acquire only the required information without any error. To resolve this problem, there are therefore provided an information reading apparatus comprising a receiving means which receives first and second broadcast signals, an information reading means which displays and reads the first broadcast signal received by the receiving means as first image information, a storage means which stores the second image information contained in the second broadcast signal, and an extraction means which extracts a part of the second image information stored by the storage means, wherein the information display means displays a part of the image in the second image information extracted by the extraction means superimposed on the image of the first image information, and reads it.

The invention provides primary access server determination method and device for dual-machine redundancy backup. The method comprises the following steps of: respectively associating two sets of BFDs (Bidirectional Forwarding Detection) between a first access server and a second access server; lowering the priority of the access server by one series from the current configuration priority when a set of BFDs associated with the first access server and/or the second access server are switched off; and lowering the priority of the access server by two series from the predetermined reference priority when the two sets of BFDs associated with the first access server and/or the second access server are switched off, wherein the access server the current priority of which is high is used as the primary access server. In the invention, through associating the proper dual BFDs for the primary access server and the standby access server and setting up the reference priority used as the reference, the condition that the priorities of the primary access server and the standby access server are same cannot be generated, thereby avoiding the dual-primary problem in the dual-machine hot backup.
