摘要:
A Viterbi decoding apparatus for decoding received data by Viterbi decoding comprising a state metric memory circuit, a path memory circuit, and a path decode word decision circuit. The state metric memory circuit stores state metric information obtained by ACS (Adder, Comparator, Selector) processing. The path memory circuit stores path selection information provided by the ACS processing. The path decode word decision circuit weights a plurality of bits with a path decode word of each state according to its degree of likelihood based on state metric information supplied from the state metric memory circuit, cumulatively adding each path decode word obtained by the weighting operation, and comparing a cumulative value obtained by the cumulative adding operation with a preset threshold value to determine decode words. This setup provides sufficiently reliable decode words by a small amount of hardware and in a short processing time to decode, within an average information rate, convolutional codes having information amounting to 30 Mbps or more used in high-definition TV etc.

A probe transmitting section (216) in a packet receiving terminal (210) sends a probe packet to a second radio channel (320) at fixed intervals. A probe analyzing section (117) in a packet sending terminal (110) detects a burst loss on the basis of a state of reception of the probe packet. When a burst loss detection is detected, a predictive retransmission control section (118) predicts that a data packet transmitted during the period of the detected burst loss among data packets sent from a priority processing transmission buffer (115) to a first radio channel (310) is a data packet lost on a receiving side, reads the data packet from a retransmission buffer (114), and then sends the data packet to the priority processing transmission buffer (115). A real-time property can be ensured while a packet loss is overcome in a radio environment.

A picture transmitting apparatus transmits, to a picture receiving apparatus, a picture as a predetermined area of an omnidirectional picture. The picture receiving apparatus displays a portion of the transmitted picture which corresponds to a viewpoint. When the viewpoint is moved, information of the movement is transmitted from the picture receiving apparatus to the picture transmitting apparatus, and a picture corresponding to the new viewpoint is transmitted from the picture transmitting apparatus to the picture receiving apparatus. The picture receiving apparatus displays a portion of the received picture which corresponds to the viewpoint.

The present technology relates to an information processing apparatus and an information processing method that can reproduce high-quality stereoscopic images with low delay.An interpolation data storing unit (112) stores received L image data and R image data as interpolation data. A line-based multiple data link managing unit (105) manages a management table in which the numbers of packet errors in the L image data and the R image data of each line block and the like are registered. Based on the management table, an image data input switching unit (106) outputs the reception data when both of the numbers of packet errors in the L image data and the R image data contained in the reception data are smaller than a threshold value, and outputs interpolation data that corresponds to the reception data, is stored in the interpolation data storing unit (112), and has a smaller number of errors than a threshold value when both of the numbers of errors are not smaller than the threshold value. The present invention can be applied to a relay device that receives stereoscopic image data, for example.
