Patent ID: 8335264

Claim:
An image information transmission apparatus, comprising: a stream transmitting section configured to output encoded stream data; a division instructing section configured to generate dividing point information for designating a dividing point of the encoded stream data; and a parallel stream transmitting section configured to divide encoded stream data that is output by the stream transmitting section and side information necessary for decoding from halfway along a stream that is extracted based on the encoded stream data into a predetermined number of parts at dividing points that are designated by the dividing point information, perform parallelization thereof, and transmit data obtained as a result thereof to a stream decoding section on a receiving side, wherein the parallel stream transmitting section further includes: a stream dividing section configured to divide input encoded stream data into a predetermined number of parts at dividing points that are designated by the dividing point information from the division instructing section and sequentially output data obtained as a result, and at the same time to sequentially output side information that is divided into a predetermined number of parts that is the same as the number of divisions and is extracted based on the encoded stream data; a storage section configured to sequentially store encoded stream data and side information that are sequentially divided at the stream dividing section; a parallel controller configured to perform control for causing encoded stream data and side information to be sequentially divided at the stream dividing section and sequentially stored at the storage section; and an output section configured to parallelize and output a predetermined number of pieces of encoded stream data and side information that are stored in the storage section.
