Abstract
The present technology relates to a recording apparatus, a recording method, and a program capable of avoiding a buffer overflow at the time of reproduction. Each packet is separated from a packet string, and information indicating an arrival timing of each packet is output. The packet is divided into divided packets having a size which does not cause a buffer overflow, and a packet arrival time of each divided packet is embedded in a header of the divided packet. The present technology is applied to the recording apparatus.
Claims14
A recording apparatus comprising:
- an electronic processor;
- and
- a memory including a multiplexing/separating program, a packet dividing program, a packet arrival time generating program, and a packet arrival time applying program, the multiplexing/separating program, the packet dividing program, the packet arrival time generating program, and the packet arrival time applying program being executable by the electronic processor to perform a set of operations comprising
- separating each packet from a packet string,
- dividing a packet that is separated from the packet string into divided packets, each divided packet of the divided packets having a predetermined size,
- generating a packet arrival time associated with the each divided packet, and
- embedding the packet arrival times that are generated in corresponding headers of the divided packets,
- wherein the memory further includes a recording program,
- wherein the electronic processor is further configured to execute the recording program,
- wherein the set of operations further includes recording the divided packets in which the packet arrival times are embedded in the corresponding headers to a recording medium,
- wherein the predetermined size corresponds to a size of an additional buffer which is added to be a data buffer size same as that at the time of receiving, viewing, and listening by a reproducing apparatus, for reproducing the divided packets that are recorded to the recording medium, to avoid a buffer overflow,
- wherein the predetermined size is (Rp/(Rp-Rr) x (size of the buffer)),
- wherein a reading maximum rate at the time when the reproducing apparatus reproduces the each divided packet is the Rp, and
- wherein a reading maximum rate at the time when the each divided packet is recorded is the Rr.

A recording method comprising:
- separating, with an electronic processor, each packet from a packet string;
- dividing, with the electronic processor, a packet that is separated from the packet string into divided packets, each divided packet of the divided packets having a predetermined size;
- generating, with the electronic processor, a packet arrival time associated with the each divided packet;
- embedding, with the electronic processor, the packet arrival times that are generated in corresponding headers of the divided packets;
- and
- controlling, with the electronic processor, a recording medium to record the divided packets in which the packet arrival times are embedded in the corresponding headers,
- wherein the predetermined size corresponds to a size of an additional buffer which is added to be a data buffer size same as that at the time of receiving, viewing, and listening by a reproducing apparatus, for reproducing the divided packets that are recorded to the recording medium, to avoid a buffer overflow,
- wherein the predetermined size is (Rp/(Rp-Rr) x (size of the buffer)),
- wherein a reading maximum rate at the time when the reproducing apparatus reproduces the each divided packet is the Rp, and
- wherein a reading maximum rate at the time when the each divided packet is recorded is the Rr.
