Definitions

  • the present invention relates to a personal video recorder.
  • the aim of the present invention is the realization of a personal video recorder which can record into the external memory in a fast and secure manner.
  • the personal video recorder realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a control unit which provides the TS packets containing the voice and image signals that belong to the channel to be recorded to be encrypted by means of an encryptor without applying any decoding and encoding operations and the encrypted TS packets to be recorded into the external memory.
  • the demux filter records the TS packets containing the voice and image signals that belong to the channel to be recorded into the memory unit. After reading and encrypting the TS packets recorded in the memory unit, the encryptor records the encrypted TS packets into the memory unit. The portable media driver reads the encrypted TS packets recorded in the memory unit and records them into the external memory.
  • TS packets containing voice and image signals that belong to the channel to be recorded are recorded into and read from a dedicated first memory area in the memory unit by the demux filter, encryptor and portable media driver simultaneously.
  • the personal video recorder of the present invention is suitable for being used as a television or receiver.
  • the TS packets containing the voice and image signals that belong to the channel to be recorded are recorded into the external memory without applying any decoding and encoding operations.
  • the personal video recorder of the present invention records the images in the broadcast signals, multangular images in 3D broadcasts, voices (the voice data containing more than one language, music etc. for the same channel), subtitles (can be in multiple languages), channel/broadcast data packets (teletext, electronic program guide etc.) that belong to the channel to be recorded into the external memory as TS packets and can play the recorded TS packets.
  • Pw The TS packets containing the voice and image signals that belong to the channel to be watched (K2)
  • F2 A second memory area dedicated for recording the TS packets containing the voice and image signals that belong to the channel to be watched (K1) (Pw)
  • the user desires to record a channel (K1) from the digital broadcast signals reaching the personal video recorder (1) and received by the receiver (2), he/she transmits the data of channel to be recorded (K1) to the control unit (10) by means of an interface (not shown in the figure).
  • the data of channel to be recorded (K1) is transmitted to the demux filter (4) by means of the control unit (10).
  • the demux filter (4) rules out the incoming TS packets according to their headers and records the TS packets containing the voice and image signals that belong to the channel to be recorded (K1) (Pr) into the memory unit (5).
  • the encryptor (7) After reading and encrypting the TS packets (Pr) recorded in the memory unit (5), the encryptor (7) records the encrypted TS packets (Pe) into the memory unit (5).
  • the portable media driver (9) reads the encrypted TS packets (Pe) recorded in the memory unit (5) and records them into the external memory.
  • the broadcast signals received by the personal video recorder (1) are in DVB format.
  • the encrypted TS packets (Pe) read from the external memory by means of the portable media driver (9) are decrypted by the encryptor (7) and recorded into the memory unit (5).
  • the TS packets (Pr) recorded in the memory unit (5) are read by the decoder (6) and converted to a suitable format in order to be supplied to the output means (8).
  • the encrypted TS packets (Pe) recorded in the external memory and containing the voice and image signals that belong to the channel to be recorded (K1) can only be watched in the personal video recorder (1) wherein the recording operation is performed.
  • the portable media driver (9) receives the encrypted TS packets (Pe) from the first memory area (F1) and records them into the external memory.
  • the operations of reading the voice and image signals, which belong to the channel to be recorded (K1), by the demux filter (4), encryptor (7) and portable media driver (9) simultaneously from the first memory area (F1) and recording them are directed by means of the control unit (10).
  • the memory unit (5) is a RAM (Random Access Memory).
  • the data of channel to be watched (K2) is transmitted to the demux filter (4) by means of the control unit (10).
  • the demux filter (4) rules out the incoming TS packets according to their headers and records the TS packets containing the voice and image signals that belong to the channel to be recorded (K1) (Pr) and the TS packets containing the voice and image signals that belong to the channel to be watched (K2) (Pw) into the memory unit (5).
  • the TS packets (Pw) which are recorded in the memory unit (5) and which belong to the channel to be watched (K2) are read by the decoder (6) and converted to a suitable format in order to be supplied to the output means (8).
  • the memory unit (5) comprises a second memory area (F2) which is different than the first memory area dedicated for recording the TS packets containing the voice and image signals that belong to the channel to be recorded (K1) (Pr) (F1), and wherein the TS packets containing the voice and image signals that belong to the channel to be watched (K2) (Pw) are recorded.
  • F2 second memory area
  • the personal video recorder (1) is a set-top-box.
