摘要:
To reduce operation load associated with encoding. There is provided a program causing a computer (10) to perform a procedure. The computer includes memory (11) storing segments (31-A, ...) created by dividing transmission data (31) and encoding information (32) including encoding patterns (32-1, ...) representing combinations of the segments. The procedure includes generating, for each encoding pattern, an encoded data piece (34-1, ...) by performing an operation (33) on the combination of the segments corresponding to the encoding pattern, and storing the encoded data piece in the memory; and performing, when part (35) of the segment combination represented by a second pattern, which is an encoding pattern corresponding to targets of the operation, includes the segment combination represented by a first pattern, which is the encoding pattern corresponding to an encoded data piece (34-2) stored in the memory, the operation using the encoded data piece corresponding to the first pattern.
摘要:
The present invention relates to a method for creating a correction matrix for errors in transmitting multimedia data packets at non-constant rate between a sender terminal and at least one receiver terminal, said multimedia data packets constituting elements of said correction matrix. Such a method of creating a correction matrix is particular in that the correction matrix has dimensions which are determined as a function of a maximum rate of said multimedia data packets at the input of said sender terminal, and in that said multimedia data packets are arrayed in the correction matrix at regular time intervals, an absence of a multimedia data packet noted for a given time interval being represented in said correction matrix by a void.
摘要:
The Mojette Transform is applied to the storage of data. The data is organized in k data chunks for which m parity projections are generated using the Mojette Transform. In case of an update of one or more data chunks, a partial update (instead of a complete regeneration) of the parity projections is performed.
摘要:
A picture decoding apparatus and picture decoding method are disclosed where header data is decoded using either fixed or variable length decoding, whereas the picture signal is decoded using arithmetic decoding.
摘要:
A frame coding unit (13) generates individual picture signal Information from a moving picture signal Vin, and outputs a frame code value InfVal_F which Is a numeric value to be obtained as a result of coding picture signal information of each frame. A variable length coding unit (16) decomposes the frame code value InfVal_F Into unit frame code values Val_F which are basic units of coding, converts the unit frame code values Val_F, into frame code words Code_F using only a single code table (16a), and constructs a frame stream by combining the converted frame code words Code_F. A multiplexing unit (17) multiplexes a header stream which is constructed through a method equivalent to a conventional method and the frame stream and constructs a picture coded signal Str.
