Abstract

A video recording and playback apparatus which can perform the recording operation and the playback operation without a synchronous conversion circuit is provided, even if recording and playback are asynchronous. An SDI signal containing video content is coded by input processing unit 141, and the coded video data is temporarily held by input buffer 142. The coded video data is read from input buffer 142, is outputted and is stored in storage processing unit 15. Other coded video data stored in storage processing unit 15 is read and is held temporarily in output buffer 161. Reading-out of the coded video data from input buffer 142 does not synchronize with an input synchronizing signal and is performed according to the cycle of the synchronizing signal generated by external synchronizing signal detector unit 12, and the coded video data read out is transmitted to storage processing unit 15.

Dependent claims

A video recording and playback apparatus, comprising:

an input processing unit configured to receive data containing video data having a 1st synchronizing signal inputted at a 1st rate, to code said video data received and to output coded video data;
an input buffer configured to hold temporarily said coded video data outputted by said input processing unit and to output said coded video data held at a 2nd rate faster than said 1st rate;
a storage processing unit configured to store said coded video data outputted from said input buffer and to read out coded other video data stored at a 3rd rate faster than said 1st rate;
an output buffer configured to hold temporarily said coded other video data read out from said storage processing unit and to output said coded other video data;
and
an output processing unit configured to receive a 2nd synchronizing signal and said coded other video data outputted from said output buffer, to decode said coded other video data according to a cycle of said 2nd synchronizing signal and to output said other video data decoded.
