Abstract: According to one embodiment, an input analog video signal is digitized, and an OSD signal to which a second scaling process is performed is added to the digital video signal to which a first scaling process is performed. At this point, display modes of the digital video signal and the OSD signal are changed by causing pieces of scaling data, supplied for the first and second scaling processes, to be variable based on a predetermined operation.

Abstract: According to one embodiment, a heat radiating apparatus comprises a shielding case having holding panels thereof arranged at locations substantially opposite to a circuit component to extend from a flat panel of the shielding case, which extends substantially parallel to a circuit board, towards the circuit board so as to cover the surface of the circuit board on which a circuit component is mounted. The head radiating apparatus further comprises a heat sink attached to the holding panels of the shielding case for coming into direct contact with the heat conductive sheet on the circuit component when the circuit board is covered with the shielding case.

Abstract: According to one embodiment, an input analog video signal is digitized, and an OSD signal to which a second scaling process is performed is added to the digital video signal to which a first scaling process is performed. At this point, scaling data corresponding to the number of pixels of a panel in which the OSD signal is displayed is supplied in order to perform the second scaling process.

Abstract: According to one embodiment, when a digital video signal is inputted, a decoding process is performed to the digital video signal to add a digitized OSD signal, a first scaling process is performed to the digital video signal, and the digital video signal is outputted. When an analog video signal is inputted, the analog video signal is digitized to perform the first scaling process, and the OSD signal to which a second scaling process is performed is added to the digitized video signal. The second scaling process is lower than the first scaling process in quality.

Abstract: According to one embodiment, fixing plates are formed to a shield case which covers a circuit board including a circuit component. When a heat sink, which has bent heat dissipation plates and can be accommodated in a shield case, is attached to the fixing plates and the surface of the circuit board is covered by the shield case, the heat sink comes into contact with the heat conduction sheet attached to the circuit component.

Abstract: When the low bit rate coding is effected in a recording system 1A, a signal is coded and recorded in a hierarchical structure. On the reproduction side, the type of a recorded signal (the low bit rate coded signal of the hierarchical structure, non-hierarchical structure, conventional analog recording or the like) is determined by a determination system 1E and the operation modes of a digital signal processing system 1G and an analog signal processing system 1F are set. The analog signal processing system processes a reproduced signal when it is analog signal. The digital signal processing system processes a reproduced signal when it is a digital signal or when a reproduced output from the analog signal processing system is processed in a digital manner.

Abstract: A video data recording/reproducing apparatus is designed to effect the high density recording for low bit rate coded data, correct the error with high reliability and reproduce only the main signal. For this purpose, an error correction circuit corrects the error in a transmission path by use of a parity code added by a parity adding circuit on the transmission side. A switch selects one of outputs of the parity adding circuit and error correction circuit according to whether the parity code is contained in the transmission data or not. A recording/reproducing circuit causes an output of the switch to be recorded. At the time of reproducing operation, the error correction circuit corrects the error in the recording/reproducing operation by use of the parity code contained in the reproduced signal.
