Embodiment Construction

[0019] An apparatus 100 for recording during pause and replay functionality using rewritable disk media 102 according to the inventive arrangements is illustrated in block diagram form in FIG. 1 . The rewritable disc medium 102 is embodied as a rewritable DVD. The device 100 is capable of writing to or reading from a rewritable DVD 102 . The device includes a mechanical assembly 104 , a control portion 120 , a video / audio input processing path 140 and a video / audio output processing path 170 . The assignment of most blocks to different sections or paths is self-evident, while the assignment of some blocks is for convenience purposes and is not critical to the understanding of the operation of the device.

[0020] The mechanical assembly 104 includes a motor 106 for rotating the DVD 102 and a pickup assembly 108 used to move over the rotating disc. A laser on the pickup assembly burns spots on the spiral track on the disc or illuminates spots already burned on the track for r...

Abstract

A method for recording a program during pausing and playing back the program utilizing a disk medium, comprising the steps of: upon initiating a pause, recording the program onto a disk medium as a first pattern of recorded segments alternating with a second pattern of unrecorded segments; jumping back to the first recorded segment of the first pattern upon termination of the pause; and, alternately playing back the recorded segments of the first pattern and recording the program onto the unrecorded segments of the second pattern. An apparatus for implementing the method can comprise a controller having: a first mode of operation for recording the first pattern initiated responsive to a command to initiate a pause; a second mode of operation initiated responsive to a command to terminate said pause and jump back; and, a third mode of operation for playing back the first pattern and recording the second pattern.

Description

technical field [0001] The present invention generally relates to methods and apparatus for providing advanced working features for audio and / or video programs recorded on disc media such as recordable digital video discs. Background technique [0002] Various devices have been developed to enable consumers to record video and audio programs for later presentation. Such devices include video tape recorders, video cassette recorders, recordable compact discs, and most recently recordable digital video discs (DVDs). A DVD can only be recorded once, and what follows is essentially a DVD read-only memory, acronym DVD-R. This acronym is also commonly used to refer to write-once or recording-once technology. Several formats exist for DVDs to be recorded on, erased or re-recorded, ie overwritten or rewritten. They are acronym DVD-RAM, DVD-RW and DVD+RW. Up to now, no unified industry standard has been accepted. The acronyms DVD-RAM, DVD-RW, and DVD+RW are also used generically...
