CONTROL METHOD FOR AN INFORMATION PROCESSING DEVICE
A count value of a clock for reproduction is stamped in a receive packet of a program A from a tuner as a first time stamp, and a first operation for synchronously reproducing the receive packet is switched to a second operation for synchronously recording the receive packet based on the first time stamp and PCR added to the receive packet. In this case, a count value of a clock for recording is stamped in the receive packet as a second time stamp, and after all the receive packets, which are stored in a first buffer for temporarily storing a receive packet received by the one tuner, and in which the first time stamp is stamped, are output, the first receive packet is synchronously recorded based on the second time stamp stamped in the receive packet and PCR.
1 . A control method for an information processing device, wherein
a count value of a clock for reproduction is stamped in a first receive packet received from one tuner as a first time stamp, and when a first operation for synchronously reproducing the first receive packet is switched to a second operation for synchronously recording the first receive packet based on the first time stamp and first time information added to the first receive packet, a count value of a clock for recording is stamped in the first receive packet as a second time stamp, and
after all the first receive packets, which are stored in a first buffer for temporarily storing a receive packet received by the one tuner, and in which the first time stamp is stamped, are output, the first receive packet is synchronously recorded based on the second time stamp stamped in the first receive packet and the first time information.
2 . The control method for an information processing device according to claim 1 , wherein if the second operation is an operation of synchronously recording and also synchronously reproducing the first receive packet based on the second time stamp and the first time information, the first receive packet is synchronously reproduced based on the second time stamp stamped in the first receive packet and the first time information after all the first receive packets, which are stored in the first buffer and in which the first time stamp is stamped, are output.
3 . The control method for the information processing device according to claim 1 , wherein if the first operation is an operation of synchronously reproducing the first receive packet based on the first time stamp and the first time information, and is an operation of stamping a count value of a clock for recording in a second receive packet received from another tuner as a third time stamp, and of synchronously recording the second receive packet based on the third time stamp and the second time information added to the second receive packet, and if the second operation is an operation of synchronously recording and synchronously reproducing the first receive packet based on the second time stamp and the first time information, then the first receive packet is synchronously reproduced based on the second time stamp stamped in the first receive packet and the first time information after all of the first receive packets, which are stored in the first buffer and in which the first time stamp is stamped, are all output.
4 . The control method for the information processing device according to claim 1 , wherein if the first operation is an operation of synchronously reproducing the first receive packet based on the first time stamp and the first time information, and is an operation of stamping a count value of a clock for recording in a second receive packet received from another tuner as a third time stamp, and of synchronously recording the second receive packet based on the third time stamp and second time information added to the second receive packet, and if the second operation is an operation of recording the first receive packet and is an operation of reproducing the second receive packet, then a count value of the clock for reproduction is stamped in the second receive packet as a fourth time stamp, and
the second receive packet is synchronously reproduced based on the fourth time stamp, which is stamped in the second receive packet and the second time information, after all of the second receive packets, which are stored in the second buffer for temporarily storing receive packets from the another tuner and in which the third time stamp is stamped, are output.
5 . A control method for an information processing device, wherein
a count value of a clock for recording is stamped in a first receive packet received from one tuner as a first time stamp, and when a first operation for synchronously recording the first receive packet is switched to a second operation for synchronously reproducing the first receive packet based on the first time stamp and first time information added to the first receive packet, a count value of a clock for reproducing is stamped in the first receive packet as a second time stamp, and
the first receive packet is synchronously reproduced based on the second time stamp stamped in the first receive packet and the first time information, after all of the first receive packets, which are stored in a first buffer for temporarily storing a receive packet received by the one tuner and in which the first time stamp is stamped, are output.
6 . The control method for the information processing device according to claim 5 , wherein
if the first operation is an operation of synchronously recording and also synchronously reproducing the first receive packet based on the first time stamp and the first time information added to the first receive packet, and if the second operation is an operation of synchronously reproducing a first receive packet, then a count value of a clock for reproduction is stamped in the first receive packet as the second time stamp, and
the first receive packet is synchronously reproduced based on the second time stamp and the first time information, after all of the first receive packets, which are stored in the first buffer and in which the first time stamp is stamped, are output.
7 . The control method for the information processing device according to claim 5 , wherein if the first operation is an operation of stamping a count value of a clock for reproduction in the first receive packet as the first time stamp and synchronously recording and reproducing the first receive packet, and if the second operation is an operation of reproducing the first receive packet and is an operation of stamping a count value of a clock for recording in a second receive packet received from another tuner as a third time stamp, and synchronously recording the second receive packet based on the third time stamp and second time information added to the second receive packet, then the first receive packet is synchronously recorded based on the third time stamp stamped in the second receive packet, which is stored in a second buffer for temporarily storing a receive packet received by the another tuner and second time information.
