Abstract
Provided are an apparatus and methods for recovering video information when operating in an area that impairs an electromagnetic field of a transmit/receive signal during a video telephony of a portable terminal. A method of which includes determining a number of buffers for storing intra coded (I) frames to be received, transmitting the number of the buffers to a counterpart terminal together with a VFU signal, acquiring video information by storing I frames received from the counterpart terminal, and generating video frames using the acquired video information.
Claims20
A method for recovering video information of a video communication service in a terminal, the method comprising:
- determining a number of buffers for storing intra coded (I) frames to be received;
- transmitting, to a counterpart terminal, the number of buffers for storing the I frames;
- receiving a plurality of the same I frames according to the determined number of the buffers from the counterpart terminal;
- acquiring video information by storing I frames received from the counterpart terminal;
- and
- generating video frames using the acquired video information.
A method for recovering video information of a video communication service in a terminal, the method comprising:
- receiving a Video Fast Update (VFU) signal comprising a number of buffers for storing intra coded (I) frames, from a counterpart terminal;
- generating a plurality of the same I frames according to the received signal;
- and
- transmitting to the counterpart terminal as many generated the same I frames as the number of the buffers.
An apparatus for recovering video information of a video communication service in a portable terminal, the apparatus comprising:
- a video communication manager for determining a number of buffers for storing intra coded (I) frames, for operatively transmitting, to a counterpart terminal, the number of buffers for storing the I frames, and for generating video frames by acquiring video information from the I frames;
- and
- a Micro-Processor Unit (MPU) for controlling reception of a plurality of the same I frames according to the determined number of the buffers from the counterpart terminal.
An apparatus for recovering video information of a video communication service in a portable terminal, the apparatus comprising:
- a video communication manager for, in response to receiving a Video Fast Update (VFU) signal which comprises a number of buffers for storing intra coded (I) frames, generating a plurality of the same I frames and transmitting to a counterpart terminal as many generated I frames as the number of the buffers.
A mobile communication system for recovering video information of a video service, the system comprising:
- a first terminal for generating video frames by acquiring video information from intra coded (I) frames;
- and
- a second terminal for, in response to receiving a signal requesting transmission of the I frames, generating and transmitting a plurality of the I frames to the first terminal.
