A recording system for an emergency response unit includes a first data collection device configured to record a first video, audio or data segment with an incident identifier and transmit a message including the incident identifier. A second data collection device may receive the message and, as appropriate, record at least a second video, audio or data segment with the incident identifier, allowing the first segment and the second segment to be associated using the incident identifier. In other embodiments, a first recording device may begin recording video, audio or legal evidence data with an incident identifier, and a control system may receive a message including the incident identifier from the first recording device, identify one or more additional recording devices located within a certain distance of the first recording device, and obtain recordings from the one or more additional recording devices.

An example method includes, based on an adjustment to a first displayed volume control, instructing the first playback device to adjust playback volume level; based on an adjustment to a second displayed volume control, instructing the second playback device to adjust playback volume level; after sending the commands, instructing the first and/or second playback device to process an audio stream into a first and/or second channel and to reproduce a respective one of the first and second channel, wherein the grouped first and second playback devices provide multi-channel sound; and based on an adjustment to a third displayed volume control, instructing the first and/or second playback device to adjust a group volume level for both the first and second playback devices.

According to one embodiment, a disk device includes a housing including a sidewall, a magnetic disk, a wireless communication device including a first communication antenna, and a first insulating member. The sidewall includes a first through portion. The first insulating member closes the first through portion. The first communication antenna is located in the first through portion, is disposed spaced from the housing, and wirelessly communicates with an outside of the housing.

Embodiments are described herein that provide a media playback system controller with multiple graphical interfaces. In one aspect, a method is provided that involves (a) causing a graphical display to provide a first graphical interface including at least (i) a first input region and (ii) a first representation of a media item, (b) receiving a first input data indicating a selection within the first input region, (c) based on the received first input data, causing the graphical display to provide a second graphical interface including at least (i) an active region, (ii) an inactive region, and (iii) a second representation of the media item, (d) receiving a second input data indicating a selection within the active region, and (e) based on the received second input data, causing the graphical display to provide one or more media playback controls.

A method of scanning content comprises receiving an input signal indicating that content being displayed is to be scanned, sensing a duration of the received input signal, and scanning the content at a rate based at least in part on the sensed duration of the received input.

A multimedia visual progress indication system that provides a cache bar that is overlaid onto the program material or displayed on a dedicated display. A cache bar indicates the length of a recording session or the length of stored program material and expands to the right when material is being recorded. Index and/or bookmark indicators are displayed next to the cache bar. A position indicator moves within the cache bar and tells the user visually where his current position is within the program material. Numeric time or counter mark of the current position is displayed in the vicinity of the cache bar. The trick play bar and its associated components are displayed for a predetermined time period.

An example method includes, based on an adjustment to a first displayed volume control, instructing the first playback device to adjust playback volume level; based on an adjustment to a second displayed volume control, instructing the second playback device to adjust playback volume level; after sending the commands, instructing the first and/or second playback device to process an audio stream into a first and/or second channel and to reproduce a respective one of the first and second channel, wherein the grouped first and second playback devices provide multi-channel sound; and based on an adjustment to a third displayed volume control, instructing the first and/or second playback device to adjust a group volume level for both the first and second playback devices.
