摘要： A method and an apparatus for playout scheduling in a Voice over Internet Protocol (VoIP) system are provided. The method includes acquiring Pulse Code Modulation (PCM) samples by decoding a received packet; setting a first scale ratio according to a length of PCM samples stored in a playout buffer based on a preset scale ratio table; setting a second scale ratio by predicting a packet delay; setting a final scale ratio using the first scale ratio and the second scale ratio; and adjusting the length of the acquired PCM samples at the final scale ratio.

摘要： Provided is a method of sharing a storage space. The method includes posting a storage space to a sharing platform by a space provider, connecting to the sharing platform where the space user finds the storage space by a space user, transmitting a lease request to the space provider, determining the lease request by the space provider, and making a payment by the space user. In addition, in order to post an advertisement for the storage space, the space provider may capture an image of the storage space, connects to the sharing platform where the space provider posts the storage space, input storage space information, and upload the image of the storage space.

摘要： Provided is a method of reporting traffic violations using a vehicle black box image. The method of reporting traffic violations using a vehicle black box image includes preparing an image of the traffic violation, connecting to a website where a user reports the traffic violation and inputting traffic violation information. The image may be prepared by capturing the image of the traffic violation by a vehicle black box and storing the image in a separate storage medium other than the vehicle black box.
