Live & Play Function*

The PDW-F800/700 camcorder has a Live & Play function

that allows users to check both playback signals

(images already recorded) and incoming camera

signals (images seen through the viewfinder)

simultaneously, and sequentially output them without

any switching noise. Both signals are fed to their

respective output and viewfinder connectors

independently, and can be viewed at the same time.

This allows users to frame the next shot, adjust the

exposure, and then focus the lens while the camcorder

is playing back the pre-recordings from the disc. For

instance, the camcorder can be used to perform the

following three stages of a news broadcast:

1. The introduction to a news report (Output of incoming

camera signals)

2. Pre-recorded clips (Output of playback signals)

3. The conclusion of the report (Output of incoming

camera signals)

*1: Only one of the following functions can work at any one time:

1. Live & Play function

2. Focus Magnification

3. Letter Box mode in SD down-conversion

4. In-phase output between HD and SD.

Affordable MPEG TS Option for Field and

Satellite Transmission

The HDCA-702 MPEG TS Adaptor, which can be docked

onto the PDW-F800/700 camcorder, transmits an MPEG

Transport Stream (TS) of MPEG-2 MP@HL via DVB-ASI

output. Transmission can be simultaneous with the

PDW-F800/700 recording to disc. The bit rate is

selectable from 15 Mbps to 43.25 Mbps in 10-kbps steps,

which is suitable for material transmission via microwave

and satellite modulators. The frame pixel size is 1440 x

1080 or 1280 x 720. When the bit rate is 35 Mbps or

higher, 1920 x 1080 mode can be selected instead of

1440 x 1080. In addition, the HDCA-702 can output

MPEG-2 MP@H-14 (HDV 1080) at a rate of 25 Mbps over

the i.LINK connector.

Shockless Gain Control

A wide choice of gain and an easy-to-use control system

are remarkable features of the PDW-700 camcorder. By

setting gain to the gain selector or assignable switches,

the user can easily access the desired gain.

And the transition to each gain value is extremely

smooth thus eliminating undesirable abrupt changes to

the overall image.
