  • Patent number: 10594437
    Abstract: The present disclosure relates to a receiving apparatus and a method therefor which are capable of decreasing a processing load and efficiently improving reproduction quality. A packet accumulating unit stores packets and packet type, and another packet information. A statistics information accumulating unit accumulates statistics information (e.g., an error ratio, performance (processing condition) of the receiving apparatus, a condition of a stream, and a condition of a buffer). A packet-correcting-method selecting unit selects a packet correcting method from a packet correction table generated in accordance with the packet information and packet identification/statistics information from the statistics information accumulating unit, and supplies a packet to be corrected to a packet correcting unit in a case where the packet in process is determined to be a target of correction. For example, the present disclosure can be applied to a communication system that transmits and receives data.

When extended control with various contents can be executed by an apparatus at the time of playback, an extended attribute section in which extended control is valid is specified in accordance with the contents of the extended control. When an extended attribute section is to be uniformly specified for playback paths of the TS-VOB, a section marker for specifying a location of the extended attribute section of the TS-VOB is generated in VOB information. When an extended attribute section is to be individually specified for one playback path, a section marker specifying a location of the extended attribute section of the playback path is generated in PGC information. The generated VOB information and PGC information are written to the DVD.

In one alternative implementation, a down-sampling rate N is determined, and a time T to reconcile the recording device system time with the reference time is calculated based upon the down-sampling rate N and the difference time D. In another alternative implementation, a time T is determined, and a down-sampling rate N to reconcile the recording device system time with the reference time is calculated based upon the time T and the difference time D. In both alternative implementations, the images recorded by the recording device are down-sampled at 1/N of the original rate, and the down-sampled images are stored.

    Abstract: A memory addressing method is suitable for systems performing data compression and/or expansion such as audio and/or video systems having a variable speed data reproduction capability. According to an exemplary embodiment, a method for processing a signal such as an audio or video signal in a signal reproduction device begins by receiving the signal. The received signal is processed in dependence upon a mode of operation of the signal reproduction device representing a speed at which the received signal is to be reproduced by the signal reproduction device. The received signal is speed converted and then stored in a memory of the signal reproduction device when the signal reproduction device is in a first mode of operation. The received signal is stored in the memory of the signal reproduction device without being speed converted when the signal reproduction device is in a second mode of operation.
