摘要： Methods and systems for a personal video recorder (PVR) software buffer management to support the software passage are disclosed. A first plurality of receive buffer descriptors may be allocated for recording at least one received packet in at least a portion of a shared memory. The received packet may be recorded in the shared memory utilizing at least one of the allocated first plurality of receive buffer descriptors. A plurality of playback buffer descriptors may be allocated for playback of the recorded received packet from the shared memory. A first portion of the received packet may be simultaneously played back from the shared memory while recording a second portion of the received packet in the shared memory. If at least one of the recorded received packet is consumed, the playback buffer descriptors corresponding to a number of the consumed received packet may be de-allocated.
