Abstract: According to the present invention, a method for a travel time predicting apparatus to predict a travel time by using a travel time prediction model, including generating a first prediction model for prediction of a travel time of a vehicle that will pass through a specific area by using first traffic data that are related to a travel speed at the specific area; generating a second prediction model by modifying the first prediction model that relates to the travel speed at the specific area and is different from the first traffic data; and predicting a travel time of the vehicle that will pass through the specific area by using the second prediction model can be provided so that a travel time at which a specific vehicle passes a specific area can be more precisely predicted compared to a conventional art and predicted travel time information can be promptly and precisely provided to the user.

Abstract: Provided is an apparatus and method for coding and decoding multi-object audio signals with various channels and providing backward compatibility with a conventional spatial audio coding (SAC) bitstream. The apparatus includes: an audio object coding unit for coding audio-object signals inputted to the coding apparatus based on a spatial cue and creating rendering information for the coded audio-object signals, where the rendering information provides a coding apparatus including spatial cue information for audio-object signals; channel information of the audio-object signals; and identification information of the audio-object signals, and used in coding and decoding of the audio signals.
