摘要:
The present invention can reliably adjust the lip-sync between an video and audio at a decoder side, without making the viewer feel strangeness.In this invention, the encoded video frames to which video time-stamps VTS are attached and the encoded audio frames to which audio time-stamps ATS are attached, all received, are decoded, generating a plurality of video frames VF1 and a plurality of audio frames AF1. The video frames VF1 and audio frames AF1 are accumulated. Renderers 37 and 77 calculate the time difference resulting from a gap between the reference clock for the encoder side and the system time clock stc for the decoder side. In accordance with the time difference, the timing of outputting the plurality of video frames, one by one, on the basis of a timing of outputting the plurality of audio frames, one by one. Hence, the lip-sync can be achieved, while maintaining the continuity of the audio.

This invention realizes correct adjustment of lip-syncing of video and audio on a decoder side. According to this invention, a plurality of encoded video frames given video time stamps VTS and a plurality of encoded audio frames given audio time stamps ATS are received and decoded from an encoder side, and the resultant plurality of video frames VF1 and plurality of audio frames AF1 are stored, a time difference which occurs due to a difference between the clock frequency of the reference clock of the encoder side and the clock frequency of the system time clock stc of the decoder side is calculated by a renderer 37, 67, and video frame output timing for sequentially outputting the plurality of video frames VF1 frame by frame is adjusted based on audio frame output timing for sequentially outputting the plurality of audio frames AF1 frame by frame, according to the time difference, resulting in realizing the lip-syncing with keeping sound continuousness.

A signal from a tuner is outputted to a primary display. An analog signal from another tuner is digitally compressed, subjected to an encrypting process, transmitted to a secondary display by a wireless LAN, and displayed by an LCD of the secondary display. An output of a digital tuner is displayed by the primary display. A video signal of 480I is transmitted to the secondary display. A signal inputted through the Internet is decoded and sent to the primary display. The signal is sent to the secondary display in the compressed state without being decoded and the decoding process is executed in the secondary display.

The present invention realizes a video coding apparatus that is simple in configuration and can avoid video display quality deterioration due to an overrun of video coding processing. The video coding apparatus is provided with a coding means for bringing video into coding processing on a frame basis with a first coding processing method; a processing time detecting means for detecting coding actual processing time required for coding processing on the frame; a delay calculating means for calculating processing delay time of coding processing on the frame based on coding predicted processing time given to the coding processing and the coding actual processing time; a coding load controlling means for, in a case where the processing delay time on the frame is greater than or equal to a predetermined threshold value, causing a subsequent frame to undergo coding processing with a second coding processing method bearing coding processing load lower than in said first coding processing method, and thereby processing time of frames after occurrence of an overrun is shortened for recovery from the overrun so that a frame skip due to occurrence of an overrun is prevented to enable avoidance of video quality deterioration.

An analog signal from a tuner 22b is digitally compressed, subjected to an encrypting process, transmitted to a secondary display 3 by a wireless LAN, and displayed by an LCD 46 of the secondary display 3. An output of a digital tuner 23 is displayed by the primary display 2. A video signal of 480I is transmitted to the secondary display 3. A signal inputted through the Internet is decoded and sent to the primary display 2. The signal is sent to the secondary display 3 as it is in the compressed state without being decoded and the decoding process is executed in the secondary display 3.
