Abstract (en)
[origin: WO9912332A2] A video recorder comprises an input (14) for receiving a digital television signal which is fed via an interface circuit (15) to a buffer RAM and error correction circuit (16). A control and timing circuit (13) passes this signal from the buffer RAM (16) to a tape encoder (17) which converts the code n-bits at a time into a 2" level code thus reducing the data rate by I/n. This reduces the data rate to one which can be recorded by a VHS recorder. On replay the inverse operation is carried out using the tape decoder (19), buffer RAM and error correction circuit (16) and output interface (20) to provide a replayed digital television signal at an output (21). A further embodiment includes a digital video encoder/decoder to enable analogue television signals to be recorded in digital form.
